🎧 START pod: Jack Brown, Founder, Lark: “The E2E testing layer for AI-driven development.”
Description
The way to make software faster was always: make the code happen faster
AI solved that
Cursor, Claude Code, Replit...
Building is nearly instant now
So what's slow?
Knowing if it actually works.
When AI writes your feature, someone still has to answer: did it break everything else?
That's the new bottleneck. Not creation. Validation
Jack Brown is building Lark to solve exactly this.
An AI QA engineer that writes tests, keeps them updated, and continuously validates
There's the building, and then there's the thing that lives on after the building
Lark is focused on that second half
