I Spent $0 on Ads. Here’s How Authentic Conversations on Threads Built My Profitable SaaS

My ad spend for bolta.ai is, and has always been, $0.

That’s not a humblebrag for a long time, it was a necessity. As a bootstrapped founder, I didn’t have a marketing budget. What I had was a belief that the best way to sell a product to a community is to first become a genuine member of it.

Traditional marketing felt like shouting at people from a distance. I wanted to have conversations. So, I made a bet that I could build a profitable SaaS by treating Threads not as a broadcast channel, but as a giant, digital coffee shop and It worked.

This is the story of how I turned authentic, one-on-one conversations into a real business, and how I built my own tool, bolta.ai, to manage the process without burning out.

The Anti-Marketing Strategy: Just Show Up and Be Human
In the early days, my strategy had one rule: Don't sell anything.

Instead, I focused on two things:

Listening: I spent hours just reading conversations between other founders on Threads. What were they struggling with? What tools did they hate? What were their small, daily frustrations?

Helping: When I saw a question I could answer, I’d jump in with a detailed, helpful response. No links, no pitches. If someone was celebrating a small win, I’d be the first to congratulate them. If they were venting about a problem, I’d share a similar experience.

This wasn't about lead generation; it was about building trust. I wasn't a brand; I was Lucia, the founder who was also trying to figure things out. People started recognizing me. We’d have back-and-forth discussions in the replies. These weren't "leads" they were peers.

The Turning Point: When My Process Became My Product
The "conversation-first" approach was incredibly effective. People started asking me what I was working on. When I told them I was building a Threads scheduling tool, they were eager to try it because they already trusted me.

But this created a new, massive problem.

The very strategy that was building my business was becoming unsustainable. I was spending so much time crafting posts, remembering to publish them, and engaging in conversations that I had no time left to actually build the product or support my first few users.

I was on the verge of burnout, trapped by the success of my own manual process.

This is where bolta.ai was truly born. It wasn't just a product idea anymore; it was a lifeline I needed to build for myself. I needed a way to automate the consistency of my presence so I could focus my energy on the authenticity of my conversations.

How I Use bolta.ai to Manage an "Authentic" Workflow
People think automation and authenticity are enemies. They’re not. You just have to automate the right things. I don't use bolta.ai to fake conversations. I use it to start them.

Here’s my exact weekly workflow:

Batch the Conversation Starters: On Sunday, I spend about an hour writing out a handful of "pillar" posts for the week. These are the types of high-value content I was writing manually before: a tactical tip, a lesson from a recent failure, or an open-ended question for other founders.

Schedule Everything in bolta.ai: I load all these posts into bolta.ai and schedule them to go out at optimal times during the week.

Focus on the Replies: Now, my job isn't to post anymore. My job is to engage. When bolta.ai publishes a thread, my phone lights up with notifications. That’s when my real work begins. I jump into the replies, answer every question, and have real, human conversations.

bolta.ai handles the tedious, repetitive task of posting, which frees up my mind and my time to be fully present for the community interaction. It’s the engine that ensures I show up consistently, so I can focus on being authentic when it matters most.

Your Takeaway: Automate the Task, Not the Relationship
Building a business without a budget forces you to be creative. For me, it meant realizing that the most powerful marketing isn't marketing at all—it's genuine human connection.

If you’re a founder trying to grow, my advice is this:

Stop broadcasting, start conversing. Find where your people are and become one of them.
Listen more than you talk. Your best product ideas will come from the problems you hear people discussing every day.

Automate for consistency, not for fakery. Use tools to handle the repetitive parts of your workflow so you can save your energy for the human parts.
This is how I built a profitable SaaS with a $0 ad spend. I just talked to people, listened to their problems, and built a tool to solve the biggest one I had.
