Portuguese AI startup DeepNeuronic acquired by Motorola Solutions

Portuguese AI startup DeepNeuronic has been acquired by Motorola Solutions. The financial terms were not disclosed. Founded five years ago by Vasco Lopes and Bruno Degardin, DeepNeuronic develops software that converts standard cameras into real-time analysis systems. The technology uses AI to interpret video footage as it is captured, transforming it into immediate operational information that allows organisations to respond to incidents as they occur. The Covilhã-based company currently operates in airports, bridges, motorways, petrol stations, industrial units, and commercial spaces. It serves clients in Portugal and has a subsidiary in Brazil focused on mobility and security operations. DeepNeuronic's technology will be integrated into Avigilon, Motorola Solutions' video security platform, making it available to customers in over 100 countries.
