Yaro Starak, founder of InboxDone

Yaro Starak has been around the block, building everything from e-commerce to education businesses. His latest project, an agency called InboxDone, recently hit $2M/yr.

Here's Yaro on how he did it. 👇

The first million

I've been an entrepreneur since I was 19. My first business was a website about the Magic: The Gathering trading card game, where I built up an e-commerce store and card trading community. After that, I had an online agency where I helped university students connect with contractors who offered editing services.

In 2005, I discovered the world of blogging and very quickly dived into becoming a content creator. I started a podcast, wrote an email newsletter, and then released my first course in 2007. That was the beginning of an education business and I spent the next decade selling my own digital teaching products and coaching. This was when I broke seven figures in income for the first time.

Today, I am the cofounder and Chief Marketing Officer of InboxDone, which has been my business for the last eight years. Our agency sells one service: We provide executive assistants who take over replying to emails, managing schedules, and completing other tasks and processes for busy entrepreneurs, executives, and leaders.

We're just about to hit the $167k per month income level, which I believe qualifies us to say we're a $2M/year business; although, of course, it will take a full year for us to reach that as we only just hit that monthly number.

Starting InboxDone

The idea for InboxDone actually started all the way back in the early 2000s with my previous editing agency business. At the time, I was basically a one-man show, running a lot of the core functions for that business, except for delivering the main service that I hired contractors to do. This meant that I spent a lot of my time inside my email inbox.

I realized if I ever wanted to travel, have freedom – all the things that popular books like "The 4-Hour Work Week" talk about – I would have to delegate managing my email to someone else. So that's what I did. I hired a friend who was about to become a mother, and she took over managing my inbox and replying to emails for me. 

This was a life-changing moment. I went from having a lot of work to do to only a couple of hours per week. The day-to-day operations were managed by my friend because she managed all the emails and routine tasks. 

Although I had this idea all the way back in the early 2000s, I wasn't able to act on it until around the year 2016 because I was so busy with my online education business.

In 2016, to test whether this idea could work, I partnered with one of my email executive assistants at the time. Her name is Claire, and she became my cofounder.

We did a very simple experiment to see if this business had legs. I wrote an email to my newsletter offering a service where the same people who managed my email could manage your email. In response to that email, five people showed interest, three of them booked calls, and two of them signed up for a $1,000/month plan to manage their inboxes. Everything grew from this start.

Start with services

Our initial service offering was straightforward because my cofounder had already been delivering the service for me and my education business. 

The big question was whether the systems and processes that we developed to manage my email would apply to other people, especially because entrepreneurs have different businesses, different tools, different ways of operating – even different personalities!

One thing we did that was smart was to not just offer general virtual assistant services like so many other agencies and freelancers provide. We focused on executive assistants and made email the core problem that we solved.

The great thing about starting with a service is you don't have to build anything. There was no software to code. There was no product to purchase like an e-commerce business has to do. We simply delivered a service and were paid for it upfront each month — immediately. We had cash flow straight away. 

That being said, because I already had some money in the bank and some assets, I made the decision to not take any money out of this new company and instead use what little profit we had to pour it back into marketing for growth. 

It wasn't until our fourth year that our business finally had enough cash flow and profit that I started to take income from it.

My cofounder was able to take income straight away because she initially delivered the core service that we offered. This was fantastic because we could validate that there was enough income to both pay the contractor (first my cofounder, today our team) and return profit as an operating company. 

Paying a premium

Our revenue model is very simple: We charge a monthly recurring fee for our services. That monthly fee can expand or contract based on the number of hours clients need help from our executive assistants. 

The entry point is our standard $1,995/month plan. We also offer a full-time hours plan at $4,995 per month. 

When I started this business, I knew one of the key strengths we would have is that the service we offer targets a problem that never stops. Everyone gets emails every single day. 

That being said, in order to make this business work, I knew we would need a certain type of talent because email is difficult to handle. You cannot just put any kind of low-cost overseas virtual assistant inside your inbox and expect to get a good result. 

Over the years, we have steadily increased our prices. This was necessary because we've increased the amount we pay our team in order to continue to attract and retain talent. Our team is predominantly North American (Canadians and Americans) whom we pay American rates, which is far higher than the $5-$10/hour paid in countries like the Philippines and India. 

Paying customers are the only validation

When I was coaching entrepreneurs, I noticed my clients kept running into the same problem. People underestimate how hard it is to attract a paying customer. They just don't do enough to reach people with their offer.

Often these people get excited about what they're selling but not how they're going to sell it. It's so easy to get caught up in the software you're building, the product you're designing, or the service you're offering and underestimate that most of your time, especially early on, is going out there and finding your first, second, third, and fourth customers.

You only truly learn when you have paying customers. These people tell you whether what you have is valuable, how much they will pay for it, why and how they're using it, and help you to reach new clients. 

I read so many business books early on and continue to do so today. They're motivating, they get me excited to build my business, but they never do the most important thing. They do not give you real experience of actually serving customers. 

Growing to $10k/mo

To start with, we had one advantage: My existing audience from my newsletter, blog, and podcast. This was enough to get our first two beta test clients. 

From there, I was able to continue leveraging my own audience, including my social media following on Facebook and Twitter, to grow us to the point where we had about 6-7 paying clients. This got us up to almost $10,000 a month within a year.

Unfortunately, that's where things stopped. I just couldn't get any more customers from my existing audience. 

Early growth experiments

Then, I started to experiment with new methods of reaching potential customers. We sponsored a conference. I started appearing on podcasts as a guest expert. I also began to build out the content on our website with the hopes of attracting some customers organically from Google. 

The conference returned nothing and was a waste of money. Almost all the podcasts returned nothing aside from incoming links to our website, but there were a couple of podcasts that sent us one or two new clients. Sometimes the podcast show hosts even became clients.

The content I wrote for our blog initially did nothing. Over time, thanks to incoming links from the podcasts I was appearing on and also links from my blog, which had good search authority, we did start to rank higher in Google. 

Google has since then become a small but reliable source of new clients, sending us one to two per month. That being said, I can't always be sure which of those clients came from a Google paid ad or from organic search results. 

Speaking of paid ads, we began experimenting with Google paid search ads using a small budget to see if we could hit the right keywords to bring in new clients. That budget has grown over the years, however, Google remains only a small but consistent source of new clients.

Late-stage growth experiments

In the last few years, we experimented with YouTube ads and LinkedIn ads. While YouTube so far has returned nothing, LinkedIn has become as effective as Google — a small but consistent source of clients.

Over the years, we have also experimented with other one-off campaigns, including newsletter advertising, ads on Twitter, cold email, LinkedIn direct messages, and speaking at events. The only source of new clients that has moved the needle has been referrals. 

As our client base has grown, naturally the amount of referrals we get from our existing clients has increased. Today we attract new clients from Google (both paid and organic), LinkedIn ads, referrals, and connections through people who know me from my previous work as a blogger and podcaster.  

Run cheap and quick experiments

My advice for anyone looking to start and grow a company when it comes to marketing is to understand that there is no solution that works all the time. Just because someone gets a result with one channel doesn't mean it will work for you, and vice versa. If the channel didn't work for someone else, that doesn't mean it won't work for you. 

The key is to run quick and cheap experiments to see if you get any indication that something is working. Then double down on what is working, refine it, get better at it, and expand.

Go all in on one project

As an entrepreneur, I tend to think about other ideas constantly. If my current active business is not growing or not stimulating in a way I'd like it to be, I start thinking about other projects, experiments, or businesses I could start. 

InboxDone definitely had stunted growth because I wasn't 100% all in during many of the early years. That's not to say that the business was dying or failing. It was always moving forward, but not at a pace that it could have if I put all of my energy into it. 

This became quite obvious because when I did finally decide to put all of my energy and all of my focus into this one business, it immediately started to grow more quickly. The bizarre thing is, the business grew more rapidly even though I wasn't really doing much more. Because I had my entire energy oriented towards this one project, it's almost like the universe just decided to reward us with more clients!

Learning from churn

One of the biggest challenges with any subscription-based business is churn. In our case, we keep churn low by solving the problems that our clients care about the most. If we can give our clients back 1, 2, or even 3 hours per day, that's an incredible return on their investment. 

I'm proud to say that our churn has stayed below 4% for almost the entire time we've run our business. This is only possible because of our amazing team and the process we go through to match our clients with the right assistants, leading to long-term relationships.

Of course, writing this down makes it sound easy. It's not. Every single year, we've had to solve problems. We learn from what happens when a client cancels. We improve systems, continue to source great talent. All while trying to juggle the balance between how much we charge, how much we pay our staff, how much is left over to pay an internal management and hiring team, and of course leave some profit for the business. 

Choose the right industry and model

The biggest lesson I can pass on to anyone getting started or anyone new to entrepreneurship is to carefully consider the industry and business model you start with. 

My first business, selling Magic: The Gathering cards, had tiny profit margins and focused on a very small industry. I also quickly outgrew the game. 

With my second business, an editing agency, I had better profit margins and I started to build a team to help me. Yet, eventually, I grew tired of this business too because I wasn't excited about promoting what I was selling. 

With my blog, podcast, and education business, this was the first time I really felt alignment with what I was selling, the processes I had to do on a day-to-day basis, and the profit margins. I made good money, enjoyed my work, and had a small team to help me. 

Today, with InboxDone, we have a larger team (80 people as I write this), and a business that mostly operates without me being involved. It’s a real company, and something every day I am excited to continue working on.

What's next?

I've learned from my past. I'm focusing 100% on my one project, my one business – InboxDone

As Chief Marketing Officer (CMO), my goal every day is to figure out how we can reach new people and get new customers. 

In the short term, I'm focused on reaching larger clients. You might call this enterprise-level services. These are clients who, instead of needing help for just one or two of their team, have 10, 20, 30, even a hundred staff members who need to get time back from executive assistants. 

Hence, right now I'm spending a lot of my time learning how to reach people who are decision-makers when it comes to hiring executive assistants at larger companies. 

I continue to work with my marketing team to refine our current distribution channels that grow our core offering of email management services. 

In terms of revenue goals, I have one clear destination – to reach $1M per month in sales. I'm not sure if that's going to take us one year or 10 years, but I'm really excited about the journey to get there.

    @Yaro

    Are you a team of 80 persons and doing $167K/month?

    Doesn't make sense. So revenue is just $2k/person/month?

    Paying team members say $2k for 160 hrs means just $12.5/hr which is same as that of low cost labor in Asia, South America or Eastern Europe.

    1. 2

      Our team are entirely contractors. Some have one client, some have three. Every client has at least two assistants as well, so they have a backup. Even if a client signs up for a full time plan with us, that will usually mean 3 of our team supporting them, rather than just one, which makes for a bit of a 'key person' risk.

      So the short answer is how much people make is proportional to how much they want to work. This is actually a feature for our company, a lot of our team like the flexibility and remote work.

      It also makes us more stable because managing cash flow is easier and the impact of one person leaving is far less impactful.

      1. 1

        You haven't answered my question.

        Looks like you are charging your clients $40/person/hour, how much you are paying to your team?

        What's your profitability?

        1. 2

          $40 an hour is correct on most plans, less per hour on higher hour plans as things scale up for larger client needs. We're also working on some enterprise plans that will cost more per hour so we can provide additional client success management.

          Pay rates are from $17 to $35 depending on the role, time spent working with us, etc.

          There are also things like bonuses (for holiday periods, for retention rewards, for upgrade rewards, etc), a yearly cost of living bump to the hourly pay rate provided by the client directly to their assistants (applied every 12 months they stay working together - helps keep relationships good!).

          The highest per hour rates are for our senior management team, almost all of whom came through as part of our assistant team originally. This is a small team, but they are responsible for a lot of our internal workings.

          For profit margins, that as you can image changes every month - it has been anywhere from 0% to 40% over the years - depending on what costs we have each month (assistant team, management team, insurance, legal, software costs, etc) and our decisions on what to spend on marketing.

    Incredible journey, Yaro. Love how you emphasized starting with services and validating with paying customers — no fluff, just action. The discipline to reinvest early profits back into growth instead of taking income is something many overlook. Curious — at what stage did referrals start outpacing other acquisition channels?

    1. 2

      Hi Cecilia, thanks for your reply. Referrals have been sporadic for a long time. I'd say since the very start of the company we got referrals, but it would be one every now and then. In the last two years, it's become a bit more consistent. But I think the reason for that is simply we have more clients. As you can imagine, a larger client base gives you more opportunities for referrals.

      We do offer a commission to incentivize referrals, but to be honest, that's never really the main driver. It's usually simply a raving fan, someone who loves the service and is somehow connected with the right people to refer it to. Hence, they talk about it and send people our way.

    Go all in on one project

    Wondering how do you make up your mind to continue the journey and put 100% energy into this business? Unless you believe it or you have no choice, right?

    1. 2

      For me I need to feel some kind of positive movement - making sales, positive comments from customers, even small things like getting more visitors to your website.

  4. 1

    This is gold. So many parts resonate, especially the reminder that paying customers are the only real validation, and the power of going “all in” on one project.

    We’re in the early days of building something a bit different, a private AI assistant to help people organize digital clutter and it’s amazing how much your story reinforces the importance of staying lean, solving one clear pain point, and focusing hard on retention and quality.

    Really appreciate how open you were with the ups and downs, Yaro. Following along!

  5. 1

    From $0 to $2M/year, an agency must have a clear vision, consistent client value, strategic scaling, and a strong team. It is through discipline, smart marketing, and client trust that James Fleischmann has been able to achieve success.

    Congrats on the success. Love the insight. But you're website, sheesh.

  7. 1

    Congrats and thanks for sharing!

  8. 1

    thank for sharing this information

  9. 1

    Huge congrats, Yaro! Hitting $2M/year with InboxDone shows the power of consistent execution and solving real problems. Inspiring stuff!

  10. 1

    It's inspiring. thank you for sharing.

  11. 1

    Really inspiring to see how focusing fully on one project unlocked so much growth for you, Yaro. The journey from managing inboxes yourself to scaling a whole team and hitting those revenue milestones is a great example of solving a real pain point deeply. I’m working on something related—an AI-powered assistant that helps small businesses navigate complex compliance questions like HIPAA, GDPR, SOC 2, and ISO 27001, which can be just as time-consuming and critical as email management. Love hearing stories like yours because they remind me how important it is to stay customer-focused and keep iterating. Would be great to connect with others building AI tools that save busy founders time and hassle!

  12. 1

    What a sincere and generous share!

    "Goodwill bins" are outlet stores where unsold donated items are sold by the pound at ultra-low prices. Unlike regular Goodwill stores, items are dumped in large bins, and shoppers dig for hidden treasures—electronics, clothes, books, and more. Prices are dirt-cheap, making it a hotspot for resellers and bargain hunters. Find a Goodwill bins near near you by searching online or using the Goodwill store locator. Happy hunting!

  14. 1

    Great read Yaro! How did you nurture your referral channel early on? Did you do anything specific or was it mostly organic from happy clients?

    1. 2

      Hi Dana, we didn't really have a referral channel early on because we didn't have many clients. We did get the occasional referral, but having such a small amount of clients as a base meant you're just not going to get a lot of people referring.

      That might be different if you have a mass-market SAAS charging like $9/m. Getting 100 customers is not much revenue in that case, but potentially a lot more powerful for referrals.

      The true answer of what makes a referral channel work, especially for a company like ours with a higher priced service, is getting as close to a perfect match as we can to the ideal client and the highest value service we can deliver for them. Because when they experience high value, they're much more likely to talk about it behind the doors to their colleagues, friends, anyone else they know who is also drowning in emails and other tasks.

      Like most things, we find it's an 80/20 rule. There are one or two clients who will refer three or four and they make the majority of our referrals in a given quarter.

  15. 1

    Sound advice on every corner of this article.

    I'm curious tho... What has been your experience with content marketing for your agency?

    P.s. not selling marketing services.

    1. 2

      Content marketing for SEO has definitely made a difference, and continues to now as it also helps us rank in AI search.

      We have never focused on social media content marketing though, so can't really say. I can say that Facebook/Meta ads do not convert for us in our small tests, so we kept the budget towards Google and LinkedIn.

      1. 1

        I was just curious because B2B content marketing has seen a surge over the last year on Linkedin. Content marketing for SEO sounds solid tho... did you do anything special or worth mentioning?

        1. 2

          Nothing special, the usual - identify keywords (paid ads helps with this), then create solid blog posts to cover these topics, then make sure you get some incoming links to build search authority (podcast guesting helped with this).

  16. 1

    This is wild — congrats on the growth. Was there a turning point where things started accelerating? Or did it feel more like a slow build?

    1. 1

      Slow build for sure, although you can definitely feel the moments where things ramp up to a next level, and the periods of time where you feel more like you are treading water.

  17. 1

    What a great story—your early vision for the power of content writing is truly impressive. With evolving AI tools and changes in Google Search and SEO, I’m curious how we can build a business that acquires new customers organically.

    But lately, it feels like everyone is ignoring everyone else because no one’s quite sure what works anymore. I think we really need to create some magic to break through and effectively reach customers on platforms like LinkedIn and other social media.

  18. 1

    thank you for the information

  19. 1

    And by the way, what does it really take to trust your own pace in a world that never stops rushing? One of those questions we all wonder about ... and wander through too! 😄

  20. 1

    Really enjoyed this :) The steady build, the clarity of focus, and how it all grew from a real need felt very genuine! Theres something inspiring about the calm, long-game approach. Isn’t that what building something real is all about??)

  21. 1

    That is awesome story!!

  22. 1

    I've spent nearly a decade writing for Indie Hackers, where I’ve had the chance to interview hundreds of startup founders—diving deep into their wins, failures, and lessons learned along the way.

    I'm also the co-founder deltaexecutor .cc of two tools built for fellow builders:

    • dbrief, an AI-powered interview assistant

    • LoomFlows, which makes collecting customer feedback as simple as sharing a Loom

    Beyond that, I write two newsletters:

    • SaaS Watch, where I share promising micro-SaaS acquisition opportunities

    • Ancient Beat, a weekly roundup of fascinating finds in archaeology and anthropology

    This is Ben!

    I run a student-built boutique called Pattenaude Capital Partners that helps early-stage startups understand what their business is worth using real investment banking tools (DCF, comps, etc.).

    If you’re trying to raise or just want a clean valuation model to understand your numbers, I’m offering free valuations for the first few startups I work with (portfolio-building phase).

  24. 1

    This is 🔥 Yaro — love seeing indie plays turn into real momentum.

    I just launched something to help solo builders like us get structured feedback on MVPs.

    Instead of shipping and guessing, it gives you a free scorecard based on UX, clarity, and perceived value.

    Curious if this resonates with anyone here: microbets [dot] dev

    Would love feedback from the community 🙌

  25. 1

    going from $0 to $2M sounds like a wild ride! I didn't realize managing emails could be a lucrative niche—imagine all those folks trying to juggle their schedules.

    1. 1

      Thanks, yes it has been pretty wild, but a lot of fun as well. We do manage schedules for our clients. That's the second most common delegated task after email.

  26. 1

    Super Inspiring story!!!!

  27. 1

    thats so insightfull thank for sharing

  28. 1

    Very good read, thank you!

    1. 1

      No problem - happy to share some of my story!

      1. 1

        "The 4-Hour Work Week" might be the closest thing to AI before AI existed. Tim really wrote the blueprint for automating life before it was cool. Definitely one of my favorite books.

    That's such an inspiring story!

    What I liked the most was to see your passion for entrepreneurship since you were 19! Now, you're hitting big numbers which is very impressive.

    Nothing is impossible to those who believe and who work hard to make their dreams become a reality. Big up to you!

    1. 1

      Thanks David. I have to say, when I was 19-20 all the way until 26-27, entrepreneurship was very frustrating. However, there is no other way I believe to make a lot of money and have a lot of freedom, so it's the only pathway I would ever consider.

  32. 1

    This is a masterclass in focus and execution.

    The clarity on your niche, the way you stacked credibility early, and your discipline around not scaling too fast - rare to see all three.

    Curious what your biggest internal constraint was as you crossed $1M? Team, systems, or mindset?

    1. 1

      Hey Gary, honestly the way we grew has been so incremental that it's hard to say there was one biggest constraint to reach $1mil a year.

      As the person most focused on marketing, of course I'm going to say the biggest constraint is lead generation. However, I know my co-founder would say the biggest constraint at one point was hiring, and then it was building a management team, and then it was just dealing with systems and processes.

      So really it's about getting everything right, compounding on our results -- and we did it all slowly.

      1. 1

        Thanks for the insight. Appreciate the honesty around incremental growth and shifting constraints - it’s a great reminder that scaling is rarely about one big fix, but consistent execution across the board.
