How to Get Your First 100 SaaS Customers Without Guessing Where to Start.
Getting your first 100 customers sounds simple.
Until you actually try.
You have a product.
You have a landing page.
Maybe you even have a few competitors.
But then comes the question:
Where do the first 100 customers actually come from?
Do you start with SEO?
Post on X?
Launch on Product Hunt?
Make TikToks?
Run ads?
Send cold emails?
Try everything?
That's where most founders start guessing.
And that's exactly the problem we're trying to solve with Fountrail.
The first 100 customers are not 100 random people
When you're building a SaaS, it's tempting to think:
"I just need more traffic."
But traffic isn't the same as customers.
You can get thousands of visitors and still struggle to get your first paying users.
The real challenge is figuring out:
- Who actually needs your product?
- Where do those people spend time?
- What problem are they trying to solve?
- How do they currently solve it?
- What would make them switch?
- Which marketing channel should you test first?
The answers are different for every product.
A B2B analytics tool and a calorie-tracking app probably shouldn't use the same acquisition strategy.
Yet founders often start with the same generic advice:
"Post on Twitter."
"Do SEO."
"Make content."
"Run ads."
Useful advice?
Sometimes.
A strategy?
Not really.
What if you could research the path before spending months on it?
Imagine you're launching a new SaaS.
Your goal: 100 customers.
Before spending weeks creating content or running ads, you want to understand your market.
You open Fountrail.
1. Find your competitors
Start by identifying products that solve similar problems.
Not just the biggest companies.
Also smaller SaaS products targeting specific audiences.
The goal is to understand who you're actually competing with.
2. Understand how they attract users
Look at their positioning, marketing channels, content, and other available market signals.
Are they investing in SEO?
Building an audience on social media?
Using communities?
Running paid acquisition?
The goal isn't to copy everything they do.
It's to discover possible opportunities worth investigating.
3. Find gaps and opportunities
Competitor research becomes more useful when you connect it to customer needs.
What do users complain about?
What are competitors missing?
Where is the messaging unclear?
Which audiences seem underserved?
Not every complaint is an opportunity.
But some can help you rethink your positioning or product.
4. Turn research into a marketing plan
This is the part that matters most.
You don't just want a list of competitors.
You want to start answering:
What should I test first to get my first 100 customers?
For example:
- Which audience should I target?
- Which acquisition channels deserve an experiment?
- What kind of content should I create?
- What should my landing page communicate?
- Which competitors should I study more closely?
- What should I avoid spending time on?
That's the direction we're building toward with Fountrail.
The goal isn't to predict your first 100 customers
Let's be realistic.
No tool can guarantee that you'll get 100 customers.
And competitor data alone won't build your product or sell it.
But good research can help you make more informed decisions.
Instead of randomly trying five channels, you can start with a clearer hypothesis.
Instead of copying a competitor's marketing, you can investigate why their approach might work.
Instead of spending months building features, you can look for evidence that the problem is worth solving.
The goal is not to remove uncertainty. It's to reduce avoidable guessing.
This is what we're building with Fountrail
Fountrail is a platform for founders who want to research markets, analyze competitors, and build a more actionable startup strategy.
We're especially interested in helping founders answer questions like:
"I have a product. Now how do I get my first 100 customers?"
Not with generic growth advice.
But with research, context, and a clearer starting point for experimentation.
We're still early, and we're figuring out how to make this genuinely useful.
How would you get your first 100 customers?
If you were launching a new SaaS today, what would you want to know before starting your marketing?
Would you research:
- Competitors?
- Customer pain points?
- Acquisition channels?
- Pricing?
- Positioning?
- Content strategies?
Or would you just start posting and see what happens?
I'm curious what other indie hackers think.
What's the biggest challenge you've faced getting your first 100 customers?
And if you could have one piece of research before launching, what would it be?
This is a really good distinction. Especially the part about finding where buyers already show intent.
A competitor’s homepage tells you how they want to be perceived. Support forums, reviews, and migration questions often reveal what users actually struggle with.
That’s the kind of signal we want Fountrail to help founders uncover.
The goal isn’t just to find 10 channels to try. It’s to understand:
Then turn those signals into a focused first acquisition experiment.
Less guessing. More evidence behind the first 100 customers.
That’s a fair question. We’re still early, so I don’t want to pretend we have documented cases of founders changing acquisition experiments because of Fountrail yet.
But that’s exactly the outcome we want to create.
For example, a founder plans to start with paid ads, but competitor research shows that similar products are growing through SEO or communities. That should trigger a rethink before spending money.
The goal isn’t just to show founders where the market is. It’s to help them decide where to take their first step.
And eventually, measure whether that first step changed because of Fountrail.
The research angle is clear, but the real test seems to be decision change. Have founders actually changed their first acquisition experiment because of Fountrail?
I reckon the useful research for the first 100 customers is less “what channels exist?” and more “where is the buyer already showing intent?”
Competitor research helps, but it can also pull founders toward copying visible marketing instead of finding the smaller, messier places where the problem is being discussed. Support forums, review complaints, integration requests, migration questions, job posts, niche communities. Those are often better clues than a competitor’s homepage.
The one piece of research I’d want before launching is a map of repeated pain signals: who is complaining, what words they use, what workaround they’re already paying for, and where they go when the workaround breaks.
That would make the first channel test much less random.
