Founder, SlideGMM AI

Henry Yos

I've been building presentation tooling for 8 years and reviewing pitch decks for early-stage founders for almost as long. Before SlideGMM I worked on internal slide-generation tools at two SaaS startups (one acquired, one still running) and helped portfolio companies at a small accelerator with their fundraise decks. I've personally raised three rounds and reviewed 1,000+ decks across Seed, Series A, and Series B stages. SlideGMM exists because I got tired of fighting Gamma's PowerPoint export and wanted a tool that produced .pptx files VCs could actually edit.
