One government form in. A whole company out.
A Form D is dense, all caps and easy to miss. We pull out the amount, the round and the address, then link the people who signed it.

Ask the way you’d ask an analyst.
Search reads what a company does, not just its name. You get companies back, not links, sorted by how much they raised.

Every filing names a person.
Usually the founder, CEO or CFO. We link 1,789 signers to the companies they raised for, so a company search becomes a people search.
Where it lands
Capital has an address.
Each company sits at the business address on its filing, not a state average. Filter down to a single metro.
What this is, and what it isn't.
What is a Form D?
The notice a company files with the SEC when it sells securities without registering them, which is the standard route for private fundraising in the US. It is due within 15 days of the first sale and becomes public immediately.
How current is the data?
The most recent round in the directory is from September 2026. We backfill from EDGAR on a schedule rather than streaming filings in real time, so treat tinytech as a research tool, not a live alerting feed.
Why is an amount sometimes missing?
Form D lets a filer declare an indefinite offering amount, and some filings leave the figure blank. Where there is no reliable number we show a dash rather than guessing, and those rounds are excluded from every total on this page.
Is it free?
Yes. The directory, company pages, people pages, and search are open with no account required. Signing in adds saved companies. There is no card on file and nothing to cancel.
Does a filing mean a company is doing well?
No. A Form D records that a company raised money, nothing more. tinytech is a directory of public filings, not investment advice, and nothing here is a recommendation to buy or sell anything.
1,757 companies are already in there.
Open the directory and search it. No account, no card, nothing to cancel.
