YC Roaster

Hall of Roasts

The most brutal and funniest YC application roasts of the month, picked by AI from hundreds of submissions.

Jun 1 – Jul 1, 2026

Most Brutal 🔥

#1
Outflow Labs, Inc.
Layer 1 blockchain minting tokens from cryptographically verified solar energy generation using hardware-level signing at point of production.
5.7
“After a year full-time and five YC applications, you have $4 in revenue and zero corporate buyers, no validator interest, and no proof anyone wants cryptographically verified RECs.”

Impressive builder with real domain expertise, but you have not proven a single corporate buyer will pay for this.

Why featured: Five YC rejections, one year full-time, $4 revenue—surgical takedown of blockchain delusion.

#2
Dip Panda
Autonomous robotic inspection systems for greenhouses and industrial facilities.
3.3
“Solo founder with no prototype, no customers, no co-founder, working on two startups at once.”

Big idea, zero execution. Come back when you ship a prototype and land one real paid pilot.

Why featured: No prototype, no customers, no cofounder, two startups—brutally efficient kill shot.

#3
CanyonRift
AI agents that automate prior authorization evidence prep for hospitals by reading clinical notes and finding missing proof before submission.
6.9
“You built a working prototype in one month with synthetic data, but you have zero real users, no revenue, and you're solo in healthcare with no domain expertise.”

Fast builder attacking massive pain, but no market pull yet and desperately need a healthcare cofounder yesterday.

Why featured: Solo founder, no domain expertise, synthetic data only—exposes healthcare hubris sharply.

#4
GainGo
Security-hardened Chromium browser built exclusively for Indian retail investors, integrating trading, research, and market data.
6.9
“Impressive technical execution, but zero revenue, no signed partners, and no proof users will actually switch from Chrome.”

Sharp insight and rare technical chops, but needs one paying partner and real engagement metrics to prove this isn't just a feature.

Why featured: Zero revenue, no partners, no switching proof—dismantles impressive tech without market validation.

Funniest 😂
