David Donabedian is a Partner at Longwood Fund who focuses specifically on NewCo Formation, where he conceives, creates, and staffs new biotech companies from the ground up rather than only investing in existing ones. While serving as a Longwood executive partner, he has repeatedly stepped in as founding or interim CEO for Longwood-originated companies, including co-founding and leading Newleos Therapeutics, reflecting a hands-on builder-operator style uncommon among many VCs.

Longwood Fund operates as a small, disciplined biotech venture fund where partners actively co-found and operationally lead companies rather than just taking board seats, having co-founded 25+ companies that created $170B+ in market value and 5,000+ jobs in Boston. The fund runs its own major industry conference platform (Longwood Healthcare Leaders) that convenes top pharma CEOs, FDA leaders, and investors as an off-the-record networking forum tightly coupled to their deal-making ecosystem.
