Acquisition Opportunity

Hilco is seeking offers to acquire the intellectual property and tangible assets of Altitude Angel Ltd (In Administration) (“Altitude Angel” or the “Company”), on behalf of the Company’s Joint Administrators, Andy John and Geoff Rowley of FRP Advisory Trading Ltd.

Background

Prior to Administration, Altitude Angel was a UK-based aviation technology business recognised for pioneering digital airspace management for drones. Founded in 2014, the Company developed a suite of products that allowed pilots to plan flights and request permission, airports and landowners to review and approve operations, and national authorities to run country-level services, delivering a consistent, auditable approach to drone activity in shared airspace. The platform combined the Drone Assist operator applications, the GuardianUTM control layer for facilities, and a national GuardianUTM O/S capability for authorities.

The Company established meaningful scale and adoption, publishing usage metrics of 350,000+ direct users, connections to 64 airports and 170+ landowner sites, management of 300,000 hours of flight activity, and 90 million API calls each quarter, alongside 30 cloud customers and three countrywide deployments. These outcomes reflected a sustained programme of delivery with airports, landowners and air navigation service providers across multiple jurisdictions.

An innovator in its field, Altitude Angel delivered high-profile demonstrations of air traffic and drone traffic working side-by-side and advanced a monetised digital-permissions model that turned manual, email-based approvals into standardised, auditable workflows with optional e-commerce. The Company also introduced ARROW, a ground-based surveillance approach designed to support beyond visual line-of-sight operations, together with PRISM for low-cost radar integration, forming a flexible surveillance architecture for airports and other critical sites.

ARROW was supported by a Basingstoke manufacturing and warehouse footprint, a set of autonomous 30-metre towers that had been field-tested and connected to the Company’s platform, and a near-complete UK CAA regulatory pathway, positioning the technology as a software-led replacement for traditional visual observers.

In the financial year ending 2024, the Company generated trading revenue of approximately £1.1 million.

This opportunity offers a prospective buyer the chance to acquire the intellectual property and tangible assets behind a recognised leader in digital airspace management and surveillance, with a product set and know-how designed for rapid adoption by airports, infrastructure owners and national authorities.

Available Assets:
