Based in Los Altos, California, Antaris develops a cloud-based software platform that utilizes artificial intelligence and digital twins to design, simulate, and operate satellites. The company licenses its proprietary TrueTwin simulation environment and SatOS flight software to space mission operators, enabling them to test spacecraft virtually before physical manufacturing. Antaris has raised approximately $35.7 million in total venture funding, highlighted by a $28 million Series A round led by WestWave Capital alongside investments from Lockheed Martin Ventures. The enterprise recently secured a $1.7 million contract from the United States Space Force and successfully partnered with the Indian Space Research Organisation to launch a new demonstration satellite after a ten-month development cycle. Founded in 2021 by Tom Barton, Karthik Govindhasamy, and Shankar Sivaprakasam, the firm also signed an agreement to support a sixteen-satellite constellation for SARsatX.

# Antaris: Space Mission Virtualization Platform
Antaris is a software platform company dedicated to simplifying satellite design, simulation, and operations.[1][2] Founded in 2021 and headquartered in Los Altos, California, Antaris addresses a fundamental challenge in the space industry: getting satellites to orbit has historically been difficult, expensive, and time-consuming.[2] The company's cloud-based mission modeling platform claims to cut time-to-orbit by 2X and reduce lifetime mission costs by 10X by virtualizing every phase of the satellite mission lifecycle.[2]
The platform serves government and commercial space operators who need to design, launch, and operate satellite constellations—from single-payload missions to complex multi-vendor architectures.[2] Rather than building satellites themselves, Antaris provides the software infrastructure that makes satellite missions faster, more affordable, and less risky to execute.
Antaris was incorporated in 2021 with Tom Barton as CEO and co-founder.[1] The company emerged during a period of accelerating commercial space activity, when the traditional barriers to satellite deployment—lengthy timelines and prohibitive costs—were becoming increasingly untenable for both government agencies and private operators seeking to launch constellations at scale.[2]
The founding insight was straightforward: if you could virtualize the entire mission lifecycle through software, you could compress development cycles and reduce the experimentation costs that plague traditional space programs. This "new space" approach applies software-first thinking to problems that had historically been solved through hardware iteration and lengthy ground testing.
Antaris operates at the intersection of two powerful trends: the commercialization of space and the software-first transformation of traditionally hardware-centric industries.[2] The company rides the wave of declining launch costs (driven by reusable rockets) and increasing demand for satellite constellations from both government (national security, climate monitoring) and commercial operators (communications, Earth observation).
The timing is critical. As launch capacity becomes less constrained, the bottleneck has shifted upstream to mission design and integration—precisely where Antaris intervenes. By reducing time-to-orbit and costs, the company enables a new class of space operators who previously lacked the resources or expertise to manage complex satellite programs. This democratization of space access mirrors how cloud infrastructure democratized computing in the 2000s.
Antaris's open, integration-friendly approach also positions it as infrastructure for the emerging space ecosystem rather than a vertical player, giving it potential network effects as more operators standardize on its platform.
Antaris is well-positioned to become the operating system layer for commercial and government satellite operations—analogous to how Figma transformed design or how Stripe abstracted payment complexity. The company's success depends on achieving critical mass adoption among constellation operators and proving that software-driven mission management genuinely delivers the claimed 2X and 10X improvements.
The next phase will likely involve deepening integrations with launch providers, ground station networks, and payload manufacturers to create a more complete end-to-end ecosystem. As satellite constellations become increasingly complex and multi-national, demand for standardized, interoperable mission software should accelerate. Antaris's bet is that the future of space belongs to operators who can iterate quickly and affordably—and that software, not hardware, is the lever that makes that possible.
