POST A — Story Fourteen months ago my SaaS made $38. Not $38k. Thirty-eight dollars. I almost shut it down that week. Last month it crossed $10k in monthly recurring revenue. Nothing changed overnight. Everything changed slowly. The hardest part was never the code. It was watching people cancel and not knowing why. So I did the unglamorous thing. I emailed every churned user by hand. Most ignored me. A few replied. Those few replies rebuilt the product. Churn dropped. Trust grew. Revenue followed. I used to think growth was about getting new users. It was mostly about keeping the ones I had. If I could tell my $38 self one thing, it would be this. Talk to the people leaving before you chase the people arriving. What is the one metric you actually track every single day? #solopreneur #saas #buildinpublic #startups POST B — Contrarian take Most founders are addicted to the wrong number. New signups feel amazing. They mean nothing. I grew my solo SaaS to $10k MRR, and signups lied to me the whole way. Here is the uncomfortable truth. A signup is a promise. Retention is the proof. For a year I celebrated green charts going up. Meanwhile the back door was wide open. People joined on Monday and vanished by Friday. I was filling a leaking bucket and calling it growth. The month I stopped obsessing over acquisition, things shifted. I pointed every hour at the users already paying me. Better onboarding. Faster replies. Fewer features. Revenue climbed because people stopped leaving. Vanity metrics make you feel like a founder. Retention makes you one. Stop asking how many signed up this week. Start asking how many are still here next month. Which number are you secretly optimizing for? #saas #solopreneur #startups #growth POST C — How-to I hit $10k MRR on a solo SaaS in 14 months. Here are 5 things I would do again from day one. 1. Email every new user personally. It does not scale. That is the point. 2. Track retention before revenue. Revenue is a lagging story. Retention is the plot. 3. Ship fewer features, finish more of them. Half-built features confuse people and cause churn. 4. Write down why each user canceled. Patterns show up fast when you stop guessing. 5. Charge earlier than feels comfortable. Free users give feedback. Paying users give truth. None of this is clever. All of it is boring and repeatable. That is exactly why most founders skip it. I skipped it too, for almost a year. The day I stopped looking for hacks, the business started working.
