I used to think staying invisible was the safer move. Let the product do the talking, no personal baggage attached to it. That was my plan for the first year of building.

Then I watched two founders in my own network launch almost identical tools within a month of each other. Same market, similar pricing. The one who'd been posting his half-baked thoughts and failures on Twitter for a year got 10x the traction on launch day. The other one, better product honestly, got maybe 40 upvotes and went quiet.

That messed with my head a bit, not gonna lie.

Hey, I'm Wiki, an MD turned founder

I launched a consumer health app 3 days ago and I'm at ~100 users, all organic. I know that's a modest number, but it feels like a decent start for the first few days. I'm not planning to do paid acquisition if possible, I care more about building a community around the product than buying installs.
