4 SEC Form D filings this week ($753M combined) — a free B2B buying-intent signal most people ignore

This week alone, four companies filed SEC Form D notices totaling $753M: Emerald AI ($90.2M), Core Automation ($432.1M), ThreatLocker ($189.2M), and Valoros ($31.4M).

Form D is filed with the SEC within 15 days of a private round closing — public, factual, free, and available days-to-weeks before it hits TechCrunch or a press release. For anyone selling into funded companies, that's the window where budget is freshest and almost nobody else is reaching out yet.

I built Funding Signals to turn raw EDGAR Form D filings into a scored, enriched lead feed (company, industry, amount, contacts): https://fundingsignals.net/?utm_source=indiehackers&utm_medium=post

Free tier if you want to see this week's filings for your own niche. Happy to answer questions about how the scoring/enrichment works.

    This is a really interesting signal. Most people obsess over press releases and Crunchbase updates, but by the time those hit, the window is already smaller. Form D feels like a genuinely useful early indicator for anyone selling into newly funded companies.

    The timing is what makes this interesting.

    A public signal is valuable on its own, but the window in which people can actually act on it is a different question entirely.
