[Kacper Kapuściak @kacperkapusciak]

Extremally happy how the @TesterArmy booth turned out at next.appcon 2026!

Huge kudos to @ws_strzelczyk and @b_szafranow for sweating every last detail 🥹

We’re still here today and on Friday so come say hi to the crew!

[TesterArmy (YC P26) @TesterArmy]

Day one at @nextappdevcon Berlin. Stand 4.

We brought hoodies, tees and a few prizes that are worth the walk.

None of it is free. You have to play our game and earn it.

Our agents catch bugs for a living. Come and show them how it is done.

I designed the website. I built it. I shipped it.
