Founded in 2014 and headquartered in Oxford, Oxa builds a modular autonomy platform that combines software, hardware and fleet-management tools to retrofit and operate driverless vehicles in controlled industrial environments. The company focuses on “industrial mobile autonomy,” avoiding the complexity of open-road passenger applications in favor of repetitive, predictable driving tasks at ports, airports, warehouses and manufacturing facilities. Oxa’s system can convert a heavy-duty port truck to autonomous operation in less than a day, demonstrating rapid deployment capabilities for customers like DHL, BP and Vantec. By integrating its own sensors, compute stack and remote management software, the startup delivers a full-stack solution that can be adapted to multiple vehicle types. The new financing lifts Oxa’s total funding to more than $250 million, providing fresh capital to expand existing deployments and support upcoming commercial projects. Management intends to use the funds to scale with current partners and enter additional industrial sites globally, positioning the company for broader commercial rollout.

Optalysys is a Leeds-based deep-tech company building photonic computing hardware that integrates data movement and processing on a single chip, combining silicon photonics with traditional digital technologies. Its core product is a programmable, high-density photonic computing layer designed to accelerate compute-intensive tasks such as generative AI, post-quantum algorithms and fully homomorphic encryption. Early versions of the technology are already shipping in the company’s LightLocker™ Node servers, which target encrypted blockchain and other security-sensitive applications. Management positions photonic computing as a step-change in speed and energy efficiency compared with electronic architectures, aiming to make it a foundational element of next-generation cloud infrastructure. With fresh capital, Optalysys will speed up commercialisation of its proprietary photonic chips and broaden its programmable computing platform for AI, cloud and security markets. The firm also intends to expand into the United States to embed itself within that country’s photonics and semiconductor ecosystem. The recent £23 million financing underscores investor confidence in the size of the opportunity and provides runway for product development and market expansion.

Founded in 2017 by Dan Adams and Chris Thompson, Melbourne-based Amber Electric positions itself as Australia’s largest provider of residential solar and battery automation. The company supplies customers with real-time wholesale electricity prices and software that intelligently charges home batteries and electric vehicles when grid power is cheapest or most renewable. Amber claims to control more than 40 % of Australia’s solar-and-battery automation market and has captured a significant share of households installing batteries through the federal rebate scheme. Its platform is already being piloted by major utilities, including a 1,000-home trial with E.ON in the UK. Management says the technology allows households to lower bills while helping balance the grid and accelerate the energy transition. Amber’s growth strategy now centers on licensing its platform to international utilities, using fresh capital to “super-charge” global expansion.
