Manifund's early Timaeus grant yielded 53x return, proving donation timing beats destination

Manifund, a platform for regranting AI safety donations, makes the case that the for-profit venture capital model—where early investors back promising projects and reap outsized rewards—should apply to nonprofit funding. They argue that "funder chicken" (waiting for others to fund) slows down critical research, whereas fast, early grants can have outsized impact. Their proof point is Timaeus, a developmental interpretability research project that received its first $143k from Manifund regrantors in August 2023.

That initial funding helped Timaeus launch months earlier than otherwise possible. Over the next two years, Timaeus secured additional grants from Survival and Flourishing Fund and two larger grants from Coefficient Giving ($2m and $1.5m). In June 2026, Timaeus merged into Resolution, which received a $160m grant from Coefficient Giving—their largest AI safety grant ever. Conservative estimates attribute 20% of Resolution's funding to Timaeus, yielding a 53x return on Manifund's 2023 stake. Manifund notes that this single grant would repay their entire $5.2m regranting budget. They conclude that donors should identify early-stage projects with good taste and fund them quickly, as speed can be as valuable as the amount given.
