Buckinghamshire's funded startup activity in this dataset spans from March 2021 through July 2025, with GridServe's $134M energy round in Iver — closed July 2025 — representing the largest disclosed deal by a significant margin. The county's funding landscape skews toward undisclosed terms: three rounds from late 2024 (The First Element, BWP Group, and CREST) list no amount, a pattern common among rounds classified as Series Unknown.
Geographically, Slough and Marlow dominate the dataset, accounting for seven of the eleven companies between them. Slough leans toward technology and financial services — CoGo UK, CREST, HadsUp, and Armalytix all operate there — while Marlow's representation includes advertising and consumer goods. Seed-stage activity was concentrated in 2021–2022, with three seed rounds totaling $11M across HadsUp, Armalytix, and Bio-Sep. Lightpoint Medical's Series C ($8M, Chesham, March 2021) remains the only late-stage labeled round in the visible data.
