Thirdeye is the adversarial PM agent that weaponizes Lenny's entire podcast archive to run automated pre-mortems on your product ideas — before you waste months building the wrong thing.
No sign-up required. Just paste your idea and brace for impact.
Not another AI yes-man. A structured adversarial framework backed by real expert knowledge.
Your idea is matched against 300+ Lenny podcast transcripts using vector search to find the most relevant expert warnings and failure patterns.
The agent runs a structured pre-mortem: identifying the cognitive trap, projecting a 12-month failure timeline, and citing exact expert evidence.
Every verdict is backed by real insights from Shreyas Doshi, Marty Cagan, Teresa Torres, April Dunford, and 300+ other world-class product thinkers.
Thirdeye doesn't just say "nice idea." It makes a call.
The idea is fundamentally flawed. Killing it frees resources for better bets.
One core insight is salvageable. The execution strategy needs a complete reframe.
The idea has merit but requires 2-3 non-negotiable changes before shipping.
How much truth can you handle?
Firm but constructive. At least one salvageable insight guaranteed.
Default mode. Merciless. KILL unless evidence strongly suggests otherwise.
Obliterate every assumption. Find every failure mode. No mercy whatsoever.
Use it before you ship. Your future self will thank you.
