What has Pioneer Square Labs raised?

0 vehicles

No fund filing is on record for this firm. That is a gap in what we have read, not a statement about whether the firm has raised.

Amounts are Item 13 as filed: the target is the whole offering, and the amount sold is cumulative across amendments rather than a final close. Form D carries no per-investor amount, so a firm’s own cheque is not recoverable here.

Who at Pioneer Square Labs can lead a round?

0 named

0 partners are named across this firm’s filings, 0 of them on a fund it is deploying now.

Activity is filed board seats in the last 24 months: 4+ Active, 2–3 Selective, 1 Slowing, none Quiet. On a firm it is the total across its partners, so an active firm may be four partners taking one seat each rather than one person moving fast. It undercounts partners who invest without taking a board seat, and Form D lags a closing by weeks — so Quiet means the paperwork is quiet, not the person.

Built from SEC Form D filings, which cover US private placements — so this is most US venture activity and not all of it. For 2025 the corpus reaches 77% of deals, 62% of dollars and 53% of funds. Corpus read through 2026 Q2. A firm with no recent filing shows as the date it last filed: an absence here is our gap, not a fact about the investor. Funds that don't file, file late, or raise outside the US aren't here at all.

SEC filings are US Government works in the public domain. Think something here is wrong? Tell us — the filing settles it.
