Brooks Hosfield is a Partner at SciFi VC who previously served as Chief of Staff to Affirm's founder Max Levchin from early-stage through IPO, then built and ran Affirm Ventures as its head. He approaches investing like a product manager, working closely with founders on how financing strategy, go-to-market plans, and product roadmaps connect together rather than treating capital as separate from operations.

Notable Investments
SciFi VC is the personal venture fund of PayPal cofounder Max Levchin and his wife Nellie, built on Max's hands-on operating history in fintech and payments to give founders a specific "PayPal/Affirm playbook" operator-turned-VC rather than a purely financial sponsor. The fund focuses on companies whose competitive advantages come from hard technical feats, network effects, and complex highly regulated industries, positioning itself at the intersection of frontier science and financial engineering rather than as a standard fintech fund.
