Where do filings name Sean Klimczak on the board?

0 filed

No board seat is on record for this partner. That is a gap in what we have read, not a statement about their boards.

The company and date are what the SEC filing shows, not a statement of investment thesis. A partner can sit on a board for reasons that say nothing about what their firm funds today. The sector is not a filing value: it is Lev’s own classification of each company, shown only when we found a specific, checkable source for it; otherwise it reads “Not yet classified.” “Also on the board from” names another tracked firm with a partner on the same board, both with a clean identity match. It is not a claim either firm led or co-led the round, and “None on file” means no other tracked firm’s partner shares this specific board seat, not that no one else invested. Sorted newest first by default; click a column to change it. Something wrong? Tell us.

What sectors do their boards fall in?

Too few filings to infer a focus. 0 of 0 filed seats classified so far.

Built from SEC Form D filings, which cover US private placements: most US venture activity, 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 the date it last filed, and an absence here is our gap, not a fact about the investor.

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