Principal at Haun Ventures
Check size: No reliable Mark-specific ticket range is public. Haun invests from seed through scale from two fund families and announced $1 billion of new early- and later-stage capital in May 2026; the firm does not publish a standard ticket on the cited first-party pages.
Mark combines a builder's understanding of smart contracts and token incentives with early-stage investing. Current evidence points to founders building useful crypto businesses rather than chasing market hype, especially institutional-grade market infrastructure where fragmented liquidity, execution, financing or coordination can be unified into a superior workflow.
Use Haun's public founder route. Lead with the hard-earned market insight, the repeated workflow that exposed it and why your team uniquely understands both the technical and commercial system. For market infrastructure, quantify venue fragmentation, liquidity, order size, slippage, financing, settlement and customer demand. For token networks, explain the useful contribution, incentive budget, retention after rewards and defenses against low-quality participation.
Builders with earned, boots-on-the-ground insight; deep technical and market expertise; products born from repeated use of the problem; crypto businesses with credible customers rather than narrative momentum; infrastructure that lets institutions trade or transact at size; and token mechanisms that coordinate large contributor networks around useful output.
No personal pass list is published. Inference from his own announcement and River Markets memo: hype without a great underlying business, teams without firsthand customer or trading insight, shallow market infrastructure that ignores liquidity fragmentation and execution quality, token incentives without useful work, and founders unable to meet the higher quality bar created by institutional adoption.
Prefer founders who discovered the problem through years of building, trading or serving customers and can distinguish the real bottleneck from the visible symptom.
For market infrastructure, map liquidity across venues, order routing, slippage, financing, clearing, settlement and risk into one end-to-end workflow.
Separate a durable product, customer and revenue system from cycle-driven attention; require the company to remain compelling when the narrative cools.
Show that token rewards recruit and retain contributors who produce valuable output at scale, rather than temporarily renting mercenary participation.
As institutional prediction-market volume grows across fragmented venues, traders need a prime-brokerage layer that unifies liquidity, financing, clearing and execution; founders with years of direct trading iteration have earned the right insight.
