UK Horizons: FRC — Renaissance Philanthropy – A brighter future for all through science, technology, and innovation

Successful coordinated research programmes, like those at ARPAs, have often resulted from exceptional contractors. Many of the best contractors leveraged organisational models uncommon in academia or VC-funded startups. They combined technical ambition, a willingness to build real technology for actual users, and flexible management structures all under one roof to tackle ambitious R&D problems which made the programs a success. These organisations were driven by the pursuit of an ambitious North Star technical vision, not revenue-maximisation. And they pursued this vision with a mix of contracts and grants. We call organisations that do this Frontier Research Contractors (FRCs). Two of ARPA’s most impactful  programmes, the original internet and autonomous vehicle projects, were both led by FRCs. FRCs are also often referred to as 'BBNs' by researchers, inspired by the early internet (ARPAnet) contractor, Bolt, Beranek & Newman.
