Jack Dreifuss is a solo GP at Impatient Ventures who came to venture capital through an unusual path as a former professional poker player and competitive strategy gamer, followed by operator roles including two successful exits as CRO at SimpleLegal and CSO at Bolt, plus experience as a twice venture-backed founder. He focuses specifically on mission-critical infrastructure for automated bits and automated atoms like AI-orchestrated chip factories and unmanned naval ships, while running multiple businesses simultaneously including an early-stage consulting practice and performance marketing agency alongside his fund.
What they've been talking about across their social media accounts

- Deep interest in American dynamism and the resurgence of domestic manufacturing. Actively celebrates startups contributing to this space, pointing to a vertically integrated and data-driven oatmeal brand that successfully scaled and secured a large funding round as a prime example of this trend in action.
- Ongoing investment and advisory work across e-commerce tools, data science, and secure cryptocurrency infrastructure. Openly champions the milestones of backed startups, specifically highlighting an SMS marketing platform that recently raised funding and acquired a competitor, while also backing compliant crypto companies to partner with the government on stablecoins.
- Dedication to building out a new firm called Impatient Ventures while closely tracking broader market dynamics. Shows a practical approach to understanding the current fundraising climate by asking peers to share real examples of withdrawn term sheets to conduct market research.
- Appreciation for founders who possess strong self awareness, clear communication skills, and a healthy relationship with risk. Advises that writing is crucial for aligning team perspectives and frequently shares philosophical views on keeping ego in check while recognizing that taking risks is a fundamental part of human behavior.
Video Interview
On the screening question he asks every founder
"If this startup crashes and burns and doesn't work, what are you going to do next? It's really important for me to know that they don't already have a concocted plan B... there is no plan B. There's just a new plan A."
On the harsh reality of why VCs actually pass
Investors pass because of the business because that's what they say. But they're really passing because of you and that's okay. It's a harsh reality.
On staying yourself through the fundraising grind
"If you can relentlessly demonstrate the most authentic version of yourself and you are the leader that you think you are, the right things will show up. The gravity and the magnetism of that energy will carry forward because we're instinctual creatures. We feel first and then we think second."
On why sloppy cold emails can backfire
"How you do one thing is how you do everything. And I think that if you're thinking that you can just go the sort of like very wide, unpersonalized approach to cold emailing, like you've already failed."
On what the first slide of your deck has to accomplish
"If you can't tell me what you're doing in the first slide and I don't understand it, it's probably a bad deal or I'm too stupid to get it anyway."
