Apex Space

Apex designs and manufactures productized, configurable satellite bus platforms intended to shorten spacecraft delivery timelines from years to weeks. The company positions scaled satellite manufacturing — rather than launch access — as the remaining bottleneck in deploying proliferated, attritable constellations, and addresses it with standardized bus designs that customers configure using pre-engineered configuration packages rather than commissioning bespoke spacecraft.

The product portfolio spans three lines supporting missions in LEO, MEO and GEO. Aries supports payloads up to 150 kg (100 kg on SpaceX rideshare) with 175+ W payload orbit-average power at five-year end-of-life, and in a variant up to 120 kg on a 15-inch ESPA port with 125+ W. Nova supports up to 300 kg of payload, with additional capacity in dedicated launch configurations, and 1 kW payload power at seven-year end-of-life; it is offered in Mini and XL variants. Comet supports payloads up to 3,000 kg with 8 kW payload orbit-average power and 20 kW peak, across multiple launch configurations. Alongside the buses, Apex offers end-to-end mission services covering space vehicle analysis, payload integration and on-orbit commissioning.

Manufacturing is centred on Factory One in Los Angeles, California, described as already in rate production with peak annual capacity of more than 200 buses per year. The facility includes a cell-based subassembly production floor, a linear integration cleanroom and a 66,000-lbf vibration table, and is planned to exceed 100,000 square feet by the end of 2026 to add bus assembly, vertical integration, platform R&D and mission-services capacity. Production is coordinated by a proprietary operating system called Octopus, which links inventory management, production scheduling and assembly work instructions in a single environment.

Business model

Apex sells standardized satellite bus platforms that customers configure to mission requirements, supplemented by end-to-end mission services spanning vehicle analysis, payload integration and on-orbit commissioning. Buses are marketed with configuration packages and a self-serve online configuration flow.

Traction

The company states that buses are being built and delivered to customers at rate, that Factory One is already in rate production with peak capacity of over 200 buses per year, and that it serves a range of government and commercial customers.

Latest developments

Apex announced additional fundraising at a $2.3 billion valuation to scale high-rate satellite production for proliferated constellations, and plans to expand Factory One beyond 100,000 square feet by the end of 2026.
