Haun VenturesCheck size: No reliable Mark-specific ticket range is public. Haun invests from seed through scale and announced $1 billion of new early- and later-stage capital in May 2026; the cited first-party pages do not state a standard check.
Mark combines smart-contract and token-incentive building experience with early-stage investing. Current evidence favors useful crypto businesses rather than hype, particularly institutional market infrastructure that resolves fragmented liquidity, execution, financing or coordination into a better workflow.
Founders with earned, boots-on-the-ground insight; deep technical and market expertise; products born from repeated use of the problem; credible customers rather than narrative momentum; institutional-grade infrastructure; and token mechanisms that coordinate contributors around useful output.
No personal pass list is public. Inference from first-party evidence: hype without a durable business, teams lacking firsthand customer insight, infrastructure that ignores liquidity fragmentation or execution quality, token rewards without useful work and founders unable to satisfy the rising quality bar of institutional adoption.
Use Haun's public founder route. Lead with the earned insight and why this team understands the whole technical and commercial system. For markets, quantify fragmentation, liquidity, order size, slippage, financing, settlement and demand. For token networks, explain useful contribution, incentive cost, retained participation and abuse resistance.
Prefer founders who discovered the problem through years of building, trading or serving customers and can distinguish the real bottleneck from its visible symptom.
Map liquidity, order routing, slippage, financing, clearing, settlement and risk across venues into one end-to-end workflow.
Require a durable product, customer and revenue system that remains compelling after the cycle-driven narrative cools.
Show that rewards recruit and retain contributors who create valuable output rather than temporarily renting participation.
Growing institutional prediction markets need prime-brokerage infrastructure that unifies fragmented liquidity, financing, clearing and execution, and direct trading experience is strong evidence of founder insight.
