Hey everyone
I built Compounder because I kept wanting a simple answer to one question: what are investors like Buffett, Ackman, and Li Lu actually holding right now?
That info is public funds file it with the SEC every quarter but it's scattered across messy filings or stuck behind paywalls. So I made the clean, free version I wished existed.
It shows each investor's full portfolio, what they bought and sold each quarter, and which stocks multiple funds are buying at the same time. Data comes straight from SEC 13F filings.
It's my first project as an indie developer, built mostly with AI after hours, so it's still rough in spots. That's exactly why I'm here. Two things I'd genuinely love feedback on:
Is it clear what you're looking at when you land on an investor's page?
What's missing that would make it actually useful to you?
It's a data/education tool, not investment advice.
