Allen Control Systems raises $200M at $2B valuation

Allen Control Systems has closed a $200M round at a $2B pre-money valuation to scale Bullfrog, its AI-powered robotic counter-drone system. CEO Steven Simoni describes the company's pitch simply: Bullfrog solves a problem that has stumped every other defense contractor — shooting down small, fast-maneuvering drones with both speed and accuracy simultaneously.

“We raised $200,000,000 at a $2,000,000,000 pre money valuation. Bullfrog is essentially a robotic gimbal driven by computer vision and machine learning that solves an age old mechanical problem — in order to shoot down fast maneuvering drones, you need to be both fast and accurate. We achieved 100% kill rate against 13 Red Army flown drones in November of last year.”

The product

Bullfrog is a robotic gimbal driven by computer vision and machine learning. The core engineering insight is that conventional systems force a trade-off between speed and precision. Bullfrog eliminates that trade-off through its AI control system, which Simoni says no competitor has replicated.

The target is Group 1 and Group 2 drones — the small quadrotor-class threats proliferating on modern battlefields. In November 2025, Bullfrog achieved a 100% kill rate against 13 drones flown by a Red Army team with no advance notice of drone count, direction, or behavior.

Simoni positions lasers, which require five to fifteen seconds of dwell time on target, as poorly suited to this threat class. Bullfrog is fast enough to engage small targets at distance — and at those ranges, Simoni argues, it can also strike vulnerable points on larger threats like the Shahed when they close to last-line-of-defense distances.

Manufacturing and compute

90% of Bullfrog's components are commercial off-the-shelf, which Simoni says allows the company to ramp to thousands of units per month quickly. The system runs fully on-device — no cloud dependency, no latency over a network. The autonomous targeting loop tracks and waits for an operator "engage" command, a design Simoni says is essential for unmanned ground vehicles and surface vessels where manual remote control is too slow to hit a real target.

Go-to-market position

ACS is not currently a program of record, and Simoni frames the technology as "ahead of need" — requirements are being written now to catch up to what Bullfrog already does. The practical workaround came through Joint Task Force 401, created by the president and secretary of defense specifically to select counter-UAS technologies. ACS was selected and sent forward after the war started, giving it blanket approval for procurement across all services including the Coast Guard and Secret Service.

Team and trajectory

The company has grown from roughly 80 people at the start of 2025 to nearly 250 today, hiring approximately 50 people per month. Simoni's explicit priority is engineering depth in robotics — which he frames as a direct counterpoint to defense primes pursuing roll-up strategies at the cost of technical capability.

Simoni signals another major announcement within the next 12 to 18 months, though he gives no specifics beyond describing the product roadmap as "much, much more" capable than what Bullfrog does today.
