Cambridge funding landscape
Cambridge founders typically raise larger seed rounds because tech risk is higher, expect 12–18 months of runway rather than the London-standard 18–24, and diligence weighted heavily on the science.
Physical ecosystem hubs where Cambridge founders and investors gather: Cambridge Science Park, Babraham Research Campus, Silicon Fen, The Bradfield Centre. Being visible in these communities remains one of the highest-ROI activities for a first-time founder — most active Cambridge angels get their deal flow from other founders and portfolio companies, not cold outreach.
What deeptech investors expect
Deeptech investors accept 3–7 year commercialisation horizons in exchange for defensible IP. Expect diligence on patents, technical team pedigree, and staged milestones.
Benchmarks: Milestone-based: TRL 4 at seed, TRL 6 by Series A, first paying LOI by Series A. Revenue takes a back seat to demonstrable technical progress.
Reliefs and schemes: Innovate UK and ARIA grants routinely cover 50–70% of R&D. R&D tax credits (or the merged RDEC scheme) return 15–20% of qualifying spend, model this into your runway.
Common traps: Raising equity for pure R&D that grants would cover, and under-hiring commercial talent (deeptech dies from lack of GTM, not lack of tech).
