Built this solo. It watches SEC filings for executive and board changes, extracts the data, and shows it in real time. 2,100+ changes in the last 30 days. The comp data is interesting: average new CEO total comp is $8.4M across 284 appointments. The /explore page is fully open, no login needed.

Interesting. How do you yourself use this(I am assuming of course you built it out of a need to want to have to track this data)?

How does the comp extraction work? 8-K prose has no standard format so curious whether you're running it through an LLM or using a rules-based parser, and how you handle amendments where the actual figures show up in a later filing.

The site fails to load...it just gets stuck in a fetching state. Another downside of vibe programming.

Given this is failing due to HN hug of death, might I suggest that you do a periodic batch, save the results and serve static?

Sites going down under load is hardly a new phenomenon.

Interesting, you should save part of the data to do some caching and avoid api requests for old positions.

What would also be very interesting is a graph of relationships and movements. Let's see just how incestuous the boards really are, and what's going on with serial CEOs who move from one business to the next.

The 8-K text gets run through an LLM to extract the structured fields. It handles the variation in format pretty well. For amendments, the system picks up the amended filing and updates the record — the comp figures sometimes only appear in the amendment.
