Michelle Volz launches PAX, a $50M early-stage fund for hard tech and American dynamism founders

Summary

Michelle Volz has launched PAX, a $50M early-stage venture fund targeting hard tech, defense, and foundational infrastructure companies. Volz previously worked on Andreessen Horowitz's American Dynamism team. Target check sizes are $1–2M at pre-seed and seed.

Investment thesis

PAX moves earlier than the American Dynamism playbook typically has. Volz argues that hard tech founders face a fundraising challenge that software pattern recognition does not fit: fewer obvious proof points, longer timelines to revenue, and later-stage investors applying the wrong benchmarks. Her framework for tracking early progress runs across three dimensions: people, product, and traction. On people, that means hiring domain experts such as mechanical engineers, government sales leads, and software talent. On product, tangible milestones like test events or early user access. On traction, some signal of commercial demand, whether contracts, LOIs, or anything that shows a customer will pay. She draws a line between companies facing genuine science risk, with fusion as the extreme case, and the broader hard tech landscape, where customer demand usually exists and founders can demonstrate it.

LP dynamics

Volz says LP interest in hard tech lags founder activity by a considerable margin. Founders are leading indicators, VCs lag, and LPs lag further still. The education burden during fundraising was higher than expected. Even with the American Dynamism narrative established in venture circles, many LPs were unfamiliar with the category and pointed to the limited exit track record as a concern. A SpaceX IPO, currently discussed at a valuation around $1.75 trillion, would in her view be a category-defining liquidity event that changes LP sentiment substantially. On fund timelines, the standard ten-to-twelve-year pitch applies, though Volz notes the dynamic inverts with the best assets: LPs in a genuinely compounding position often prefer to hold rather than take early distributions.

Geography

Volz is deploying across five markets: San Francisco, LA, Austin, New York, and DC. Austin is the biggest surprise. She was initially skeptical and now sees a high concentration of strong companies there. DC is generating more deal flow than expected, driven largely by founders spinning out of companies like Palantir that relocated employees close to government customers. Engineers with families and homes in DC tend to stay, making it a viable base from which to build.

Small fund alignment

The $1–2M check size is deliberately calibrated. At that scale, each investment is significant enough to keep Volz highly motivated to help a company reach its next round, and small enough that she will not be participating in that next round. That removes the conflict of interest that can make advice from multi-stage funds awkward. She can be fully aligned with the founder on fundraising strategy without managing a position.

Sourcing edge

At the early stage, Volz says the bet is almost entirely on people. She favors founders who have worked inside the industries they are building in and who can function as magnets for capital and talent before hard proof points exist. The emerging talent pools she watches are the alumni networks from SpaceX, Palantir, and Anduril, companies that hired exceptional people, scaled fast, and are now producing founders who want to apply that experience to their own companies.
