Julie Grant co-founded and served as founding CEO of Day One Biopharmaceuticals at Canaan Partners, taking an unusually hands-on operator role for a venture investor by building the company around pediatric oncology and challenging the industry norm of prioritizing adult cancers over children. She functions as an incubator of life science startups within Canaan, founding multiple companies and advancing rapidly from associate to general partner while combining her scientific background with policy influence through roles like her appointment to the National Cancer Advisory Board.

Notable Investments
Canaan Partners originated from a 1987 management buyout of GE's venture unit and maintains a deliberately balanced 60/40 split between technology and healthcare, with both sides built to produce de novo company formation rather than just following later-stage trends. The firm runs an atypically transparent, debate-driven investment process where deals are scored 1–4 by every partner with results displayed publicly, and has executed multiple full generational transitions where none of the original partners remain after 37+ years.
