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. The filing carries no per-investor amount, so a firm’s own cheque is not recoverable here.
3 partners are named across this firm’s filings, 3 of them on a fund it is deploying now.
| Partner | Activity | Categories | Board seats | Last 24mo |
|---|---|---|---|---|
| Matthew Blumberg | Slowing | Sales & marketing tech, Crypto & web3, HR & future of work | 5 | 1 |
| Jack Sinclair | Quiet | Consumer apps & internet | 3 | 0 |
| Jennifer Lawton | Quiet | Robotics & hardware, Education | 6 | 0 |
Activity is filed board seats in the last 24 months: 4+ Active, 2–3 Selective, 1 Slowing, none Quiet. A firm's tier totals its partners, so an active firm may be four partners with one seat each. It undercounts partners who invest without taking a board seat, and filings lag a closing by weeks, so Quiet means the paperwork is quiet, not the person.
Classified sectors of Bolster Ventures’s own portfolio companies, based on 9 with a verified or cited source.
Not a filing value: this is Lev’s own classification of each company, one company one vote regardless of how many of Bolster Ventures’s partners are named on its board, shown only when we found a specific, checkable source. Companies with no source read as unclassified and are left out of the shares above.

A shared board seat: a company where filings name a Bolster Ventures partner and a partner at the other firm, both with a clean identity match. Not a claim either firm led or co-led the round, only that both are named on the same board.
