I built Parsefin because I use tools like Dataroma and WhaleWisdom to follow what well-known investors are doing, but I was frustrated by the limited number of pre-selected investors available and terrible websites. Going to the SEC's website directly is also inefficient since you have to search for funds one-by-one, and you don't see the time series data.
What Parsefin does:
Parsefin parses SEC 13F/G/D portfolio disclosure filings and aggregates portfolio changes for hedge funds and other investors (like Tiger Global, Coatue, Berkshire, Druckenmiller, A16z public holdings, etc.) into clean views. If you create a (free) account, you can follow a custom list of funds rather than just the default list you see when logged-out.
What I focused on improving vs. legacy:
* Customization: follow any fund you want rather than just a pre-set list
* Estimates of fund performance
* Modern, clean interface with search, keyboard navigation, etc.
Stack is just Next.js / React + PostgreSQL hosted on Vercel + Supabase with GH Actions.
Feel free to use if helpful and would love any feedback
