About

Agon is a London and Berlin-based defensetech company building a platform for designing, training, and iterating AI systems in synthetic battlefields, with an initial focus on training autonomous weapons systems including counter-drone systems to practice combat scenarios against adversaries 12. The company launched from stealth on 2026-07-29 with $30 million in cumulative pre-seed and seed funding — a $7 million pre-seed tranche followed by a $23 million seed round backed by XYZ Venture Capital, Lux Capital, and Northzone, with existing pre-seed investors Lakestar, 201 Ventures, D3, and angel investor David Helgason (Unity Technologies founder, who chairs the company) participating 12. Klaus Hommels of Lakestar joined the company’s board as part of the round 2. Agon was co-founded by Tristam Constant (former British Army officer and Anduril director) and Junaid Hussain (co-founder of Cambridge Aerospace and Iconic) 1.
