Comand AI
Comand AI is a Paris-based defence-tech startup founded in 2023 that builds AI software to support military command and decision-making. Its product, Prevail, helps command-centre officers plan and execute manoeuvres under time and resource constraints, using AI simulations and analysis of operational data to speed up planning. CEO and co-founder Loïc Mougeolle previously spent nearly a decade at Naval Group, and the team includes people from companies such as Palantir and OpenAI as well as the French armed forces. The company raised 8.5M euro in seed funding in December 2024 led by Eurazeo, and has worked with the French and German militaries.

Commercialization Reactor
Commercialization Reactor is a deep-tech venture creation platform and accelerator established in 2009 in Riga, ranked among the most experienced science-commercialisation programmes in Europe. It pairs scientists and researchers with entrepreneurial co-founders to build deep-tech startups, and provides up to €50k in pre-seed investment through a six-month programme focused on market and customer development. In 2024 it launched ESA BIC Latvia as the national ESA incubation centre operator, and has supported over 40 portfolio ventures across biotech, cleantech, materials, and space.
Commsignia
Commsignia is a Budapest-based V2X (vehicle-to-everything) communications company that builds the hardware, stacks, and testing tools that let cars, road infrastructure, and roadside units talk to each other using ITS-G5 and C-V2X standards — the technology layer that sits underneath cooperative driving, smart intersections, and safety-critical traffic use cases. The company sells DSRC/C-V2X OBUs and RSUs, a protocol stack used by automotive tier-ones, and a conformance-testing toolset that has become one of the most widely adopted quality-assurance environments for V2X implementations globally. Commsignia has partnered with major automotive players, smart-city deployments, and government road-safety programs in Europe and the US, and is one of the most internationally respected examples of a niche but strategically important European deep-tech company built entirely from Hungary. It pairs naturally with AImotive as the 'cars that see each other' half of the autonomy stack.
Compass AI & Tech Summit 2026

CuspAI
CuspAI is a frontier AI company building a generative-AI search engine for materials that accelerates the discovery and design of new molecules and engineered materials. Users specify desired properties (for example, selective CO2 binding for carbon capture), and the platform generates, evaluates, and optimises synthesisable candidate structures. It combines generative foundation models, deep learning, and molecular and scientific simulation, targeting applications across carbon capture, water purification, energy storage, catalysis, and industrial chemistry. The company was co-founded in 2024 by Dr Chad Edwards (CEO) and Prof Max Welling (CTO), and is headquartered in Cambridge.
