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.

What sectors do Third Rock Ventures's boards fall in?
49 companies
Classified sectors of Third Rock Ventures’s own portfolio companies, based on 49 with a verified or cited source.
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.

Not a filing value: this is Lev’s own classification of each company, one company one vote regardless of how many of Third Rock 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 Third Rock 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.
