Los Altos, California-based space technology company Antaris™ announced today the initial close of a $28 million Series A funding round to accelerate the development of its artificial intelligence-powered satellite platforms.
WestWave Capital led the investment round, with significant strategic participation from Lockheed Martin Ventures and a coalition of new and existing investors.
The capital injection aims to scale the Antaris Intelligence™ platform, a cloud-based system designed to simplify the design, simulation, manufacturing, and operation of intelligence, surveillance, and reconnaissance (ISR) and communications satellites.
The Shift Toward Software-Defined Space
The global aerospace industry currently faces mounting pressure to reduce the time and capital required to deploy orbital assets.
Traditional satellite development relies heavily on sequential hardware testing, which often delays launch schedules, inflates budgets, and limits mission flexibility.
Antaris addresses these systemic bottlenecks by introducing terrestrial cloud computing methodologies to the space domain, engineering what industry experts classify as “software-defined space missions.”
By utilizing a cloud-based software approach, operators can decouple their mission software development from physical hardware procurement.
This separation grants customers unparalleled flexibility, allowing them to dynamically manage their supply web, avoid vendor lock-in, and achieve a faster time-to-orbit with lower lifetime operating costs.
Virtualizing the Orbital Environment
Antaris will deploy the newly secured $28 million to fund the rapid expansion of its Antaris Intelligence™ platform, which powers the entire lifecycle of a satellite mission.
At the center of this proprietary technology sits the TrueTwin™ simulation environment.
TrueTwin enables aerospace engineering teams to virtually “fly” complete missions before committing to specific hardware components or finalizing manufacturing contracts.
This foundational virtualization supports advanced artificial intelligence and machine learning (AI/ML) capabilities across the entire mission lifecycle.
Specific applications of this AI integration include predictive design modeling, automated anomaly detection, complex constellation orchestration, and fully autonomous on-orbit operations.
Defense Contracts and International Momentum
The Series A funding follows a breakout year of rapid expansion for Antaris, driven largely by commercial and government adoption of its Full Mission Virtualization™ platform.
The company reported strong, sustained demand from the U.S. Department of Defense, which utilizes the platform to support critical national security and warfighter satellite missions.
For the defense sector, the ability to rapidly iterate satellite designs and simulate threat responses in a virtual environment is rapidly becoming a baseline operational requirement.
Beyond domestic defense contracts, Antaris is localizing satellite manufacturing partnerships across allied nations to build sovereign aerospace capabilities.
The company recently signed a Memorandum of Agreement (MOA) with SARsatX to develop a 16-satellite constellation in the Kingdom of Saudi Arabia.
Antaris also confirmed initial explorations into the Japanese aerospace market, working alongside sovereign governments and commercial partners to build regional ISR and communications networks.
Industry Leaders on AI-Native Missions
Executives involved in the funding round emphasize that the investment signals a fundamental shift in how the aerospace sector approaches mission engineering.
“This investment validates our vision for software-defined space missions,” said Tom Barton, CEO and Co-Founder of Antaris.
Barton noted that the company is now positioned to push the boundaries of AI-native mission design, providing operators with the speed, resilience, and confidence required in both contested and commercial space sectors.
Karthik Govindhasamy, CTO and Co-Founder of Antaris, highlighted the evolution of digital twin technology beyond basic modeling.
“Virtualizing every system element is no longer just about simulation,” Govindhasamy stated.
He explained that virtualization now serves as the baseline for AI-driven autonomy, offering mission teams a safer and more efficient pathway to software-defined space operations.
Gaurav Manglik, General Partner at WestWave Capital, brings deep experience in scaling high-growth AI companies and has officially joined the Antaris Board of Directors.
“What Antaris is building represents more than incremental efficiency,” Manglik said. “Antaris is pioneering a new model for how space missions are designed, tested, and operated, and in doing so, they’re setting the pace for both government and commercial operators.”
Strategic Implications and Market Trajectory
The backing of major defense contractors like Lockheed Martin Ventures, alongside a specialized investor syndicate including Streamlined, Acequia, HCVC, E2MC, and Possible Ventures, highlights the growing strategic importance of AI in orbital operations.
Antaris plans to immediately deploy the new capital to expand its engineering, product development, and go-to-market teams to meet rising global demand.
The company will also focus on broadening its global satellite manufacturing partnerships within regional and sovereign jurisdictions to fortify localized supply chains.
As the orbital environment becomes increasingly congested and geopolitically contested, the ability to rapidly design, simulate, and launch autonomous satellite constellations will serve as a critical differentiator for national security.
Industry observers and defense analysts will be watching closely as Antaris executes its 16-satellite Saudi Arabian constellation and further penetrates the Asian aerospace market over the coming fiscal year.
