Astranis builds small, software-defined geostationary communications satellites - about the size of a washing machine - that deliver dedicated broadband to underserved regions and governments. Founded in 2015 in San Francisco, the company designs, manufactures and operates its MicroGEO platform entirely in-house at Historic Pier 70.
Loft Orbital is a San Francisco-based space infrastructure company that flies customer payloads on standardized satellites - selling space access the way AWS sells compute. Customers skip the spacecraft-building part and ship hardware, software, or on-demand data tasks to orbit on Loft's YAM satellites.
Muon Space is a Mountain View-based end-to-end space systems company that designs, builds, and operates mission-optimized satellite constellations for climate, defense, and Earth intelligence customers. Its Halo platform pairs the modular MuSat spacecraft bus with MuOS middleware and the MuSim digital twin, anchoring high-profile programs like Google's FireSat wildfire constellation and a $44.6M U.S. Space Force environmental monitoring agreement.
John Gedmark is the CEO and Co-founder of Astranis Space Technologies, a San Francisco-based aerospace company building next-generation geostationary satellites. He previously helped shape the commercial space industry as co-founder and executive director of the Commercial Spaceflight Federation, where he influenced President Obama's 2010 decision to use commercial space transportation for NASA missions - a shift worth over $10 billion to the industry. At Astranis, he has led the company from a Y Combinator startup to a $2.8 billion valuation with a $1+ billion backlog, operating a fleet of MicroGEO satellites that bring dedicated broadband to underserved regions across Alaska, the Philippines, Mexico, and beyond.
Jonny Dyer is the Co-Founder and CEO of Muon Space, a Mountain View-based end-to-end satellite constellation company building mission-optimized spacecraft for Earth intelligence, wildfire detection, and national security. A Stanford mechanical engineer who pitched varsity baseball and co-authored rocket propulsion models, he turned Skybox Imaging into Google's $500M acquisition, ran Google Maps' data collection fleet, led Lyft's autonomous vehicle platform, and then founded Muon in 2021. The company has raised $146M in Series B funding and operates a growing constellation including FireSat - a 50-satellite wildfire-monitoring system developed with Earth Fire Alliance.
Astro Digital designs, builds and operates small-satellite systems delivered as turn-key 'Mission-as-a-Service' offerings - covering spacecraft bus, payload integration, launch, ground network and mission operations - for earth observation, communications, science and in-orbit demonstration customers from LEO to GEO.
Chris Biddy is the Co-Founder and CEO of Astro Digital, a California-founded aerospace company that has delivered 35+ satellites and operates 10+ missions in orbit. A mechanical engineer by training (M.S., Cal Poly San Luis Obispo), Biddy steered Astro Digital from an Earth observation startup into a full Mission-as-a-Service platform - cutting the cost, schedule risk, and complexity barrier for organizations wanting to put hardware in space. He previously led engineering at Canopus Systems, and has been active in the commercial smallsat movement since its early commercial days.
Christian Keil is an Investing Partner at Andreessen Horowitz on the American Dynamism team, backing startups that build for the national interest - from aerospace to defense to infrastructure. Before turning investor, he spent seven years as a top executive at Astranis, the satellite company he helped scale from a 50-person R&D shop to a 500-person aerospace-grade factory with over $1 billion in sales. He may be the only venture capitalist who has personally bought a dedicated Falcon 9 rocket. A proud Midwesterner who moved to Silicon Valley in 2017, Keil writes, podcasts, and thinks deeply about what it means to build things that matter for America.
Wardstone is a Y Combinator F25 defense startup building a global constellation of satellites equipped with space-based interceptors to kinetically destroy hypersonic and ballistic missiles. Founded by brothers Sebastian and Tobias Fischer, the company is pursuing America's Golden Dome initiative - a layered missile defense system that can engage threats in space before they reach US soil. With a $5M seed round and three successful automated intercept demonstrations during YC, Wardstone is positioning itself as a next-generation missile defense contractor targeting a $40B/year market.
