Post Description

I built this, and it’s currently just a closed-source, self-hosted engine running 24/7 on my PC, so it has basically zero “users” or, in general, anyone I know is interested in the project. You type in a private US company and it shows the filings it was legally required to submit, with most linked back to the original government source. It currently joins 16 government sources and around 17 million records.

I also already know the data itself is already public so how am I exepcting users, the point is the aggregation and linking everything back to the government source. What’s currently on the website is only a read-only slice of what I have running privately. It also computes things like risk tiers, financial trends such as operating-margin trajectories, watchlists/event streams, and as-of views showing what was knowable at a specific point in time. Some of those parts are still early and incomplete due to the project’s immaturity, and I intentionally left them out of the public demo for now due to posting "risk" tiers/labels on companies is kind of complicated as well. I might consider adding them to the existing demo companies if it is safe for me to do so though.

And i'm trying to scale it beyond that though, if I get any positive signs or in general anyone intersted in my project, or I simply shut it down and I might open-source the code. Would appreicate guidance/feedback, Also, if there is a company that is missing, drop It's name, I'll search it on my end and reply to you with it's record.

Billiver – Free financial data for 3k US companies from SEC filings

Data-first move I appreciate: EDGAR-sourced, normalized financials plus 13F aggregation and a 'cluster buying' insider flag give immediate, actionable entry points for dividend and value investors. The UI is tidy and scannable — lists, recent updates and investor portfolios are surfaced clearly — but there’s nothing radically new here (no backtesting, unclear export/API options), so it’s a very useful tool for DIY research rather than a replacement for paid terminals.
