BOW offers a universal robotics platform and a robot-agnostic SDK that let software developers program different robots using the operating system and programming language of their choice. The platform enables rapid creation, deployment and portability of robotics applications, fleet management and orchestration, and includes ultra-fast communications and AI capabilities. Originally spun out of the University of Sheffield in 2020, BOW is headquartered in Sheffield, UK and works with OEMs, system integrators and software development houses.

BOW closed a £4 million seed round led by Northern Gritstone with co-investors Finance Yorkshire and Praetura Ventures as part of the Northern Powerhouse Investment Fund II. The company intends to use the proceeds to build on commercial traction, expand its team and accelerate platform and SDK development to meet growing customer and developer demand.

The Build Chain is an online construction procurement platform that connects sub-contractors and SME housebuilders in need of materials with independent merchants. Its solution lets buyers submit a single enquiry that is automatically delivered to suitable merchants, removing the need to find suppliers, contact them manually, and chase quotes.

The company plans to expand the platform to other audiences in the construction industry over the next year. It will use new investment to recruit experienced hires across technology, operations, sales and finance to support scaling. The firm is forecasting strong growth in 2024 and beyond as it seeks to create efficiencies throughout the built environment supply chain.
