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 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.
