Case Study: How Felix Heikka Looped His Way to $10k/Month with AICofounder

Felix Heikka and David Heikka has shipped both flops and winners. The flops? Painful. Months of grinding, crickets on launch day, and the sinking feeling of “uh oh, no one actually wants this.”

The winners? Way more fun. And the secret wasn’t magical copywriting, or ads, or even being some kind of growth genius. Nope. The difference was simple: validating the problem before building.

Here’s how They looped their way to $10k/month with AICofounder, using three tight TenK 6 loops.

🎯 Loop 1: “Do people even care about this problem?”

They started with a hunch: founders don’t have a structured way to validate ideas. They just kind of wing it, waste time, and pray. (Been there.)

Instead of jumping into code, he ran the first TenK 6 loop:

• List 5 possible founder pains → wasted time, validation chaos, no user input, bloated MVPs, no feedback.
• Pick 1 → “no structured way to validate ideas” felt the strongest.
• Ship 1 → They made a survey + posted it to r/SaaS and r/indiehackers. But here’s the trick: They offered feedback in return. That bribe made it easy to get responses.
• Ask 3 → 8–10 founders filled it out.
• Measure 1 → most said “yes, this hurts” and “yes, I’d use a solution.”
• Share 1 → They shared the learnings and gave themself the green light. 🚦

🛠 Loop 2: “Okay, let’s actually build something”

Now came the fun part—building. But not feature-creep building. Loop-style building.

• List 5 → five possible features users mentioned.
• Pick 1 → the bare minimum. No fluff.
• Ship 1 → MVP in 30 days. (Because who wants to drag it out?)
• Ask 3 → They showed it back to the survey folks.
• Measure 1 → people said “yeah, I’d try this.”
• Share 1 → They announced the MVP and started onboarding testers.

📈 Loop 3: “Time to get people in the door”

With something live, They needed real users. Cue marketing loop.

• List 5 → possible channels: Reddit, X, IH, LinkedIn, newsletters.
• Pick 1 → focused on Reddit + X (where founders already hang out).
• Ship 1 → daily grind: 5 posts + 50 replies on X, then recycling the best stuff onto Reddit.
• Ask 3 → They DM’d users for blunt feedback.
• Measure 1 → target was 20 active users in 2 weeks. Result? 100 users. 💥
• Share 1 → They documented progress publicly, which pulled in even more users.

🚀 The Aftermath

Those three loops alone got AICofounder from “just an idea” → MVP → $10k+/month in revenue. After that, growth became easier. Why? Because the loops never stopped—users shaped the product every cycle.

The takeaway: if you’re stuck wondering whether to build, stop guessing. Run a loop.

👉 That’s exactly what the TenK 6 is for—List, Pick, Ship, Ask, Measure, Share. Their story is proof it works.
