Venture Partner at Craft Ventures
Check size: No personal check-size range is published. Craft attributes investments from seed through growth to Jeff, but public round totals are company financings and not his personal allocation authority.
Jeff specializes in marketplaces, particularly vertical models that go deeper than horizontal incumbents. He evaluates density, liquidity, trust, network effects, take rate, gross profit, and capital-efficient growth, and has extended that operating lens into payments and AI applications. His recent Venture Partner transition preserves an early-stage, marketplace-oriented role while Craft's broader strategy shifts toward later stages and other categories.
Map the two or more sides of the market, the acute vertical problem, trust mechanism, initial liquidity strategy, acquisition loops, match or fill rate, repeat usage, take rate, contribution and gross margins, geographic or category sequencing, and the network effect. Present burn multiple using annualized gross-profit growth, account for seasonality, and show why expansion strengthens rather than dilutes density.
Founders who understand a vertical's participants and trust constraints, start with focused geographic or category density, create clear value for both sides, and demonstrate strong product-market fit before expanding. He values network effects, thoughtful market sequencing, fast execution, large category ambition, and efficient growth measured on gross profit rather than vanity GMV.
His writing warns against horizontal marketplace clones, premature geographic or category expansion before liquidity, growth-at-all-costs, burn multiples above sustainable levels, misleading marketplace accounting, and models without a compelling value proposition for both supply and demand.
Divide net cash burn by annualized gross-profit growth, use year-over-year periods for seasonal businesses, and normalize on gross profit to avoid distortions from take rate, margins, and P&L presentation.
Launch with a narrow category and geography, prove repeat liquidity and value for both sides, expand only where participant demand pulls the marketplace, and protect density during each step.

Marketplace capital efficiency should be measured using cash burn divided by annualized gross-profit growth, with yearly periods used when seasonality makes quarterly comparisons misleading.
A labor marketplace can compound by establishing density in a few geographies and job types, expanding only on customer demand, and delivering flexibility to both businesses and workers.
A post-purchase utility can use merchant integrations and consumer order aggregation as a wedge into a broader ecommerce discovery and transaction platform.
Horizontal marketplaces are repeatedly unbundled by vertical specialists that solve a specific category's workflow, trust, and matching problems more deeply.
