Ethan Ha

I'm Ethan. I'm 19.

I build alone — not as a manifesto, because I can't pay a team and I don't want to split control. If this was going to work, I had to start from zero.

What I've shipped

  • 4 shipped software products: Insidr, Probly, Haunt, Cobble
  • 2 other product experiments: Roomhack (Shopify, paused), TeamFragile (physical, still in manufacturing)

Insidr is the bar: lean, mostly runs itself, handles refunds and support, cheap to keep alive.
