YC Pitch Deck Agent

The YC Pitch Deck Agent interviews a founder for missing facts and prepares a Y Combinator-style application deck: 10 main slides plus appendix, as a structured deck_spec.json and a short review.md. It follows Seibel's six points, the Aaron Harris slide order and Kevin Hale's design rules (large type, one idea per slide, no decoration). Seven prompt-based tools guide the pipeline: intake validation, slide-order planning, deck-spec building, a 15-rule linter (no invented numbers, a real milestone in the Ask, bottom-up market math, honest competitors, consistent figures), review writing, an optional Demo Day cut and a fact-check plan for time-sensitive YC facts. What it does not do: the tools return text and JSON only. The .pptx file is built by your own client (for example Claude with a PPTX skill or code execution), the web searches for deadlines and the standard deal are run by your client, and the lint gate is a rule the agent follows, not code that blocks it. If your client cannot build PPTX files, you still get the JSON spec and the review. Built for founders at any stage up to seed applying to Y Combinator. Not a financial model, legal advice or fundraising strategy tool.
