We are veteran technologists and serial entrepreneurs who have spent decades building modular, scalable, mission-critical systems — first on Earth, now in space.
Thomas Leavitt (CEO) co-founded the world’s first self-service web hosting company in 1994. Spent the next 25 years building IT infrastructure that served millions without breaking. Now applying the exact same playbook—standardization, plug-and-play, ruthless iteration—to spacecraft. Because someone finally has to.
John McEntee (CTO) is a startup-veteran solutions architect who has designed and produced reliable deep-tech hardware and manufacturing systems in aerospace, semiconductors, biotechnology, robotics, and photovoltaics. Holder of 17 granted patents, he has a demonstrated track record of taking complex ideas from whiteboard to volume production.
Together we became obsessed with removing the biggest barrier to space innovation: the complexity and cost of building spacecraft.
Space.Org’s Cluster Modularity radically simplifies design, integration, and testing. Standardized, flight-qualified modules snap together like building blocks — the same philosophy that powered the Internet’s infrastructure revolution is now making spacecraft as composable as cloud services.
Our web-based design platform seamlessly integrates with our online multi-vendor marketplace, where vetted partners offer instruments, software, and services, letting customers mix-and-match to create bespoke missions faster and cheaper than ever before.
Spark a new generation of entrepreneurs, researchers, and builders to launch missions that were previously impossible or unaffordable — fast-tracking the New Space economy and unlocking countless applications, many yet to be imagined.
