Ryan Kriser is a venture capital investor at Helios Capital who has built his entire career around the commercial space sector, serving not only as an investor but also as Chairman of Space for Humanity, board member of Radian Aerospace, and advisor to multiple leading space companies like Voyager Space. Unlike typical VCs, he invests through a single-family office with permanent capital that allows him to back long-term, capital-intensive space infrastructure and propulsion companies across pre-seed to Series A stages.
What they've been talking about across their social media accounts

- Enthusiasm for the commercial space sector and defense technology, particularly the shift toward fixed-price contracts over traditional cost-plus models. He actively supports the idea that space exploration is on the verge of an acceleration curve similar to the recent AI boom, citing rapid orbital reusability and NASA's embracing of innovative startups as key indicators of this shift.
- Strong belief in American dynamism and the revitalization of the country's industrial base. He frequently frames building startups as a patriotic act essential for national dominance, expressing a conviction that the next few years will see a massive resurgence in American capability and infrastructure.
- Admiration for high-agency, visionary leadership, specifically holding up Elon Musk as a primary example of how to operate. He tends to view the convergence of bold political leadership and aggressive technological innovation as the necessary path forward, suggesting a preference for founders who can articulate a grand vision for the future, such as the technological singularity or rapid advancements in air mobility like Archer.
