Who backs Boston Electrometallurgical Corp
Form D names a startup's officers and directors, not its investors. The dashboard infers them — the venture funds whose own filings and people overlap this company's rounds — and lays every Form D and amendment it filed beside the totals above.
- Inferred investors — the funds and firms behind it, from co-filings and shared people
- Every Form D and amendment as filed, with what each one stated
- Its rounds in sequence: the gap between them and whether they grew
- Everyone its filings name, linked to their other companies, with its addresses and phone numbers
Part of the Venture plan — $140/mo at launch pricing ($350 list)
