Founder story
ExploreYC was built in 2026 by developer Konstantin Borimechkov. Tired of manually cross-referencing YC directories, Crunchbase, and LinkedIn to see if startup ideas had been attempted before, he built ExploreYC. He turned scattered accelerator research into an open-source platform offering semantic search, API access, and market intelligence across 11,000+ startups.
