MISTT raises £5m pre-seed for defence data infrastructure

Expeditions leads the London startup’s financing to expand its technical team and develop a shared four-dimensional data layer.

MISTT announced a £5 million pre-seed round on November 11, led by Expeditions. Seedcamp, the National Security Strategic Investment Fund, Watchkeeper, Overmatch and FJ Labs also participated.

The London company is developing a data platform that combines location, height or depth, and time. It brings sensor and environmental information into a shared reference for autonomous systems and AI models, with defence customers as its initial market.

Led by co-founder Dan Eaton, MISTT will use the funding to hire technical and business development staff and pursue growth in the UK, NATO and US markets. Its software is designed to sit between data sources and the command-and-control, autonomy and AI systems that use them.
