Scores, Space (of 10)

Darker bar: ahead of the other company on that measure.

Positioning

Aerospacelab is a Belgian venture-backed satellite maker whose MEGAFACTORY (opening 2026) is billed as Europe's largest satellite production site (capacity 500 satellites a year), on top of existing own-design bus production heritage. It is part of the 2026 European capacity race (with EnduroSat and Muon), betting on EU sovereignty demand (IRIS2, defense constellations), with US expansion underway. Revenue is estimated at 10-100m.

Positioning

K2 Space is a US satellite maker executing a bigger-is-better thesis (its Gravitas demonstrator launched March 2026 with claimed most-powerful Hall thrusters in space, plus Mega- and 100kW Giga-class buses) from a Torrance factory designed for up to 100 large satellites a year. It has converted to anchor contracts: an SES initial tranche of 30 MEO satellites (its largest disclosed commercial win), buses for Anduril in the Golden Dome interceptor program, and a Space Force Protected Tactical Satcom bus role. It raised >$1B (a Series D in July 2026 at $6.8B, 2.3x in seven months) with >$1B in signed contracts; recognized revenue is estimated at 10-100m.
