Jeff Fluhr co-founded and led StubHub through the dot-com crash, giving him direct experience building a major marketplace during severe downturns that he now uses to advise founders on operating through tough economic cycles.

Notable Investments
Craft Ventures is founded and led by repeat unicorn founders from the "PayPal Mafia" and other iconic startups, including David Sacks of PayPal/Yammer/Zenefits, giving the fund an unusually dense operator-founder pedigree relative to most VC firms. The fund has popularized a detailed, metrics-driven B2B SaaS "playbook" and publishes a transparent "investment framework" with specific quantitative efficiency benchmarks that founders can reverse-engineer, functioning as much as an operator-education brand as a capital provider.
