Belfast's funded startup landscape across these 45 rounds spans from mid-2020 through November 2025, with seed rounds accounting for the largest share of transactions. Companies including CropSafe, Angoka, Budibase, and Overwatch Research all closed seed rounds, while Cloudsmith reached Series B with a $23M raise in March 2025 — one of the larger disclosed equity rounds in the set. Fibrus's $289M debt financing in March 2022 stands as the single largest transaction, though its structure differs substantially from the equity rounds that make up most of the dataset.
Biotechnology is the most represented sector, with Neurovalens, Dia Beta Labs, CV6 Therapeutics, Diaceutics, pHion Therapeutics, Causeway Sensors, and B-Secur all appearing in the data. AI-focused startups have gained ground recently: AMPLY Discovery raised a $2M seed in May 2025 and Simpli closed a $410K pre-seed in April 2025. Hardware companies including Axial3D ($18M, December 2024) and Sidequest ($12M Series A, October 2022) add further depth to Belfast's technical startup base.
