Airbase Emerges From Stealth

Airbase, the software startup building modern infrastructure for radio-frequency (RF) spectrum coordination, founded by Ari Rosner & Millen Anand, has emerged from stealth with a $5M funding round led by Andreessen Horowitz (a16z), joined by Squadra Ventures and Founders You Should Know. Launching with an active U.S. government agency contract, Airbase is starting by automating federal spectrum management and coordination. 

The RF spectrum underpins trillions in global GDP, enabling essential services such as 5G, GPS, radio, and critical systems, including weather monitoring, satellite networks, and autonomous drones.

Yet, as demand for connectivity accelerates, government systems responsible for spectrum allocation still rely on outdated, manual processes, creating bottlenecks that slow innovation and weaken national defense.

“Physics sets the limits of spectrum availability, but the real constraint lies in analog coordination,” said Ari Rosner, Co-Founder & CEO of Airbase. “Software-driven precision is replacing legacy friction, enabling regulators and spectrum users to operate with speed and flexibility, supported by collaboration across government, defense, and commercial sectors to deliver a modern, resilient solution.”

Airbase is transforming the spectrum from a static utility into a dynamic, software-defined resource. Under a federal contract, automation is being applied to the most burdensome aspects of spectrum coordination, reducing reliance on manual interference deconfliction and legacy database management.

This shift enables national experts to focus on complex RF engineering and policy challenges rather than time-intensive administrative workflows.

Regulatory agencies such as the Federal Communications Commission are increasingly prioritizing spectrum management modernization. “Demand for wireless spectrum has outpaced the systems that manage it,” said Julius Genachowski. “Advancing beyond fragmented, legacy infrastructure is critical to strengthening U.S. competitiveness and innovation. By applying AI and building alongside spectrum users, Airbase is well-positioned to deliver a long-needed solution.”

This urgency is echoed by leading investors. “Innovation across aerospace, telecommunications, and defense cannot continue at pace without modernizing spectrum infrastructure,” said Erin Price-Wright of Andreessen Horowitz. “Spectrum is a foundational layer of progress, and Airbase is building the technology required to unlock the next generation of critical applications.”

Beyond licensing and coordination bottlenecks, the electromagnetic spectrum has become a primary domain in an increasingly contested geopolitical landscape. Airbase has developed a unified data infrastructure integrated with live RF data layers to support Electronic Warfare (EW), tactical communications, spectrum enforcement, and Joint All-Domain Command and Control (JADC2) initiatives for the Department of War.

“Control of the spectrum increasingly defines control of the battlefield,” said Guy Filippelli of Squadra Ventures. “Current military frequencies remain vulnerable to jamming, and Airbase provides the real-time, intelligent data required for secure, dynamic spectrum access in critical missions.”
