BigBear.ai has officially finalized its $250 million cash acquisition of Ask Sage, a move that transforms the company from a services-heavy consulting firm into a dominant secure AI platform provider. The deal, completed on December 31, 2025, marks one of the largest consolidations in the defense-AI sector this year.
Why This Deal Changes the Market
The acquisition isn’t just about adding headcount; it’s about regulatory moat. Ask Sage brings a massive existing footprint that includes:
-
100,000+ Active Users: Primarily across the DoD, U.S. Army, and Air Force.
-
Rare Certifications: Ask Sage holds FedRAMP High and DoD IL5/IL6 authorizations compliance levels that are deal-breakers for federal agencies but difficult for startups to achieve.
-
Agentic Capabilities: Beyond simple chat, the platform allows for “agentic AI” that can plan and execute workflows across 150+ different LLMs.

Strategic Integration: The “Mission-Ready” Ecosystem
BigBear.ai CEO Kevin McAleenan noted that the integration creates a unified ecosystem where data, software, and mission services exist in one secure “enclave.” By combining BigBear’s predictive analytics with Ask Sage’s generative power, the company is positioning itself as the primary alternative to Palantir for government “decision advantage.”
Business Impact & 2026 Outlook
From a financial perspective, the move is highly accretive. Ask Sage is projected to contribute roughly $25 million in Annual Recurring Revenue (ARR) for 2026, representing a 6x year-over-year growth rate.

The “Publisher’s” Take
This acquisition signals the end of the “AI Experimentation” era for the government. Defense agencies are no longer looking for standalone tools; they are buying sovereign platforms that can govern and audit AI at scale. For businesses in the sector, the message is clear: Compliance is the new competitive advantage.
