What we learned from Developer Tools YC applications

“This is not an application, it is a form template with a name and tagline typed in.”

0.0/10·Cannot evaluate an application that does not exist. Fill out the form, then reapply.

“Solo non-technical founder built v1 with Claude Code in a week, no paying customers, not full-time yet, and looking for a technical cofounder.”

7.2/10·Sharp insight and real velocity, but execution risk is high. Next 60 days determine if this is real pull or well-articulated vaporware.

“You're a solo founder with zero users building three-sided infrastructure that only works if EU regulators force adoption on your exact timeline.”

4.7/10·Impressive technical architecture and rollup experience, but show me one paying customer and a co-founder before the runway burns.

“Zero traction evidence, no working prototype, no users, no revenue, just a pitch deck with unproven $50/mo pricing assumptions.”

3.9/10·Strong market and real pain point, but you give me almost no evidence that you can actually execute or ship.

“You have an MVP and a thesis, but 10 free users from conference demos is not traction, and your routing intelligence is still theoretical.”

7.0/10·Smart team with excellent timing attacking real infrastructure pain, but you need 50 daily active users and first revenue in 90 days or you're dead.

“Benchmark speedups are dramatic, but you haven't proven real customer workloads see the same gains or that this isn't a consultancy in disguise.”

7.9/10·Strong technical team with real velocity, but the next month is critical to prove production workloads validate your thesis.
