Backing founders
building at the frontier.
8:28 Fund invests in exceptional teams at the edge of AI, deep tech, and quantum — emerging from the Boston ecosystem.
We back the exceptional.
We invest in founders building at the frontier of AI, deep tech, and quantum — operator-led, Boston ecosystem focused, and purpose-driven.
Founder-first conviction at pre-seed and seed.
Operator experience, technical depth, hands-on partnership.
Anchored in the Boston and New England ecosystem.
Built with intention.
"The best companies are built by founders with clarity of purpose — and capital, when deployed with intention, compounds beyond returns."
8:28 is built on long-term conviction. We believe in backing people who are building for what matters — with patience, partnership, and a view measured in decades, not cycles.
We move at the pace of trust. We hold our partnerships across market cycles. And we invest with the confidence that exceptional founders, given time and support, reshape industries.
Where we invest.
