The acquisition follows BigBear.ai’s previously disclosed definitive agreement announced alongside the Company’s third quarter 2025 financial results and further strengthens its position as a trusted provider of secure, production-ready AI at scale. Ask Sage supports more than 100,000 users across 16,000 government teams and hundreds of commercial organizations, delivering generative AI capabilities that are operational within the most demanding security and compliance frameworks.
“Completing the acquisition of Ask Sage marks a significant milestone for BigBear.ai and accelerates our vision of delivering mission-ready AI that customers can deploy with confidence,” said Kevin McAleenan, CEO of BigBear.ai. “Ask Sage is already operating at scale in mission-critical environments, and together we are bringing to market a secure, integrated AI platform that unifies data, software, and mission services in one place.”
With the integration of Ask Sage, BigBear.ai expands its AI portfolio to include secure generative AI workflows that complement its existing mission solutions and services. The combined platform enables government and enterprise customers to incorporate AI while maintaining control over data sovereignty, model governance, and security requirements.
“By bringing Ask Sage into the BigBear.ai family, we are responding directly to what our customers have been asking for – AI that is not only powerful, but trusted, scalable, and ready for real-world missions,” McAleenan added.
BigBear.ai expects the acquisition to further enhance its growth across national security, defense, intelligence, and regulated commercial markets, while reinforcing its commitment to delivering AI solutions that move from experimentation to operational impact.
