ThesisCheck: Verify stock theses against source evidence

Hey Product Hunt, I’m Janis, the solo founder building ThesisCheck. Stock theses usually contain a mix of facts, assumptions, projections and narrative. The hard part is separating what is actually supported by source evidence from what only sounds convincing. ThesisCheck takes a ticker, listing market and investment thesis, then builds a verified-claims ledger from filings, transcripts, market data and issuer materials. The output shows which claims are supported, contradicted or missing evidence. It also discloses source and retrieval gaps instead of hiding them. ThesisCheck does not give buy, sell, hold, price-target or portfolio advice. It is built to pressure-test investment reasoning, not replace it. I’d value feedback from investors, analysts, finance creators and anyone who reads or writes stock research.
