Company profile
researched Sep 2026Birdstop is a US drone company whose current product line centers on Fealty, an autonomous security drone system for continuous site coverage. The system has three parts: a weatherproof quadcopter with optical zoom and radiometric thermal payloads, onboard AI and obstacle avoidance; a perch that serves as shelter, charging dock and sensor mast with a 360-degree camera and microphone array; and Mission Control software that handles detection, classification, dispatch, live video, patrol scheduling and audit-grade logging from a single console, with one operator able to run multiple perches.
Earlier public descriptions of the company frame it as a remote sensing business operating a nationwide network of BVLOS (beyond visual line of sight) drones and ground stations, likened to a constellation of satellites on the ground, used to inspect and monitor field assets such as power grids and telecom networks and to respond on demand to natural disasters and security breaches. The company states it holds several FAA approvals for complex BVLOS operations and patented technology including a low-altitude airspace deconfliction system. Aircraft are described as manufactured and tested in Detroit from NDAA-compliant components, with compliance claims covering NDAA, SOC 2 Type II and FAA authorization.
Founding story
Birdstop was founded by Keith Miao, previously a data scientist leading a team at Google whose remote sensing career began with satellite imagery research at the Columbia University Earth Institute.
Business model
Birdstop manufactures and deploys drone hardware (aircraft and perches) paired with its Mission Control software, sold to site operators through a quote-based inquiry process, with implementation staff supporting customer deployments.
Traction
By 2023 the company reported active drone coverage in several states and FAA approvals for BVLOS operations without visual observers, and had begun scaling production of its airspace intelligence beacon at a new Alabama R&D facility. Its team spans engineering, manufacturing, flight operations and compliance roles, with backgrounds at Google, the Earth Institute, Drone Volt, the US Air Force and NASA.
Latest developments
The company's current focus is the Fealty autonomous security drone and perch system, manufactured and tested in Detroit and marketed for 24/7 site coverage across public safety, utilities, transportation, construction and data center sites.
▸Full profile — market position, technology, go-to-market, geography, history
Market position
Birdstop positions itself as an American manufacturer of autonomous aerial security and inspection systems, emphasizing domestic production in Detroit, NDAA-compliant supply chain and FAA BVLOS authorizations.
Persistent readiness from a self-charging perch with sub-three-second launch, all-weather operation, no on-site pilot requirement, multi-site operation by a single operator, and US assembly from NDAA-compliant components alongside SOC 2 Type II and FAA authorizations.
Technology
The Fealty drone is an IP54-rated autonomous quadcopter with 45-minute flight endurance, 45 mph cruise speed, 33 mph wind resistance, an operating range of -4°F to 113°F, a 4K camera with 240x zoom, radiometric thermal imaging, RTK and 5G connectivity, and onboard obstacle avoidance. The perch provides charging, 360-degree optical and acoustic monitoring, up to 3,352 TOPS of AI compute, AES-256 encryption and a 10-mile operational range, launching the aircraft in under three seconds. Optional payloads include TDLAS-class methane sensing and LiDAR, with a spotlight and PA speaker listed as coming. Mission Control provides real-time detection and dispatch with API integrations into SCADA, CAD, VMS and access control systems. Earlier technology described includes networked UAVs and ground stations delivering real-time asset data over the internet and a proprietary low-altitude airspace deconfliction system supporting BVLOS flight.
Go-to-market
Direct enterprise sales through quote requests on the company website, supported by a director of sales, implementation manager and aviation compliance staff; FAA approvals and NDAA/SOC 2 compliance are used as qualifying credentials.
Operators of sites that require continuous monitoring, including public safety agencies, utilities, transportation, construction and data centers, as well as owners of power grids, telecom networks and other critical infrastructure; the company has also cited applicability across more than 20 industries including agriculture and first response.
Geography
Headquartered in the San Francisco Bay Area with locations listed in San Francisco and Concord, California; manufacturing and testing in Detroit, Michigan; an R&D facility in Alabama; operational coverage cited in Alabama, California and Texas.
History
The company was founded by CEO Keith Miao and has operated from the San Francisco Bay Area, with locations listed in San Francisco and Concord, California. In 2023 it raised $2.3 million led by Lerer Hippeau and opened a research and development facility in Alabama to begin scaling production of its systems, starting with an airspace intelligence beacon; at that time coverage was active in Alabama, California and Texas. The company has since positioned its manufacturing and testing in Detroit around the Fealty security drone platform.
