Sơn on building Perfeat solo

Robin — Thirty days building Perfeat alone. Worth it?

Yeah. When it’s just one person, scope is the whole game. The first week I wrote down everything I thought the app needed, then deleted most of it. What survived was: log a meal, rate it, see it later. Everything else was a distraction wearing a feature costume.

Robin — What did you cut that hurt the most?

Social. I wanted people to share meals, follow each other, the whole thing. It’s seductive because it feels like growth. But it’s a second product. I shelved it and the diary got better immediately.

Robin — How do you decide what’s in versus out, with no one to argue with?

I ask whether it helps the next meal get logged faster. If it doesn’t, it waits. Having no co-founder means no one talks me into the fun-but-wrong thing — but it also means no one stops me, so the rule has to be strict.

Robin — What’s next for it?

Get it stable in real hands, watch where people actually stop, and only then add. The fastest way to ruin a small product is to treat it like a big one.
