Deal volume hit an all-time high of 121 fundraisings, signalling an active, broad-based market.

We’ve ranked the top 100 martech companies by total equity raised (all data sourced from the Beauhurst platform).
What is martech?
Martech — short for marketing technology — covers the software, data, and AI tools that businesses use to plan, run, measure, and personalise marketing activity. It spans audience research and consumer data platforms, programmatic advertising and ad-targeting tools, content management and creative software, customer engagement and loyalty platforms, marketing analytics, and the growing layer of AI-driven content generation and personalisation tools.
Beauhurst tracks 765 active martech companies in the UK, up from 335 in the final quarter of 2015 — a 128% increase over the decade. Together, these companies have raised £2.40b, with £1.52b of that arriving since 2020 (64% of the sector’s all-time total). The 159 companies reporting full financials generated £7.46b in turnover, and the sector supports an estimated 44,840 employees across the UK.
Key findings
- GWI tops the ranking with £169m raised. The London-based company provides consumer behaviour data to marketing agencies, media organisations, and major brands, and accounts for 7.1% of all UK martech equity raised to date.
- Amplience (£165m, London) takes second place with its content management and creative experience platform for retailers, followed by Attest (£71.7m, London) in consumer research, Ogury (£70.2m, London) in mobile audience data, and InfoSum (£64.2m, South East) in privacy-safe data collaboration. The top five account for 23% of all equity raised in UK martech — a less concentrated leadership tier than most other sectors we’ve analysed.
- London hosts 57 of the top 100, followed by the South East (13), South West (6), North West (5), and East of Scotland (5). The top 100 spans 10 UK regions in total.
- Venture-stage businesses lead the top 100 (35), followed by growth-stage (33), with 18 established companies, nine exited businesses, four seed-stage and one dead. The 27 mature names (established and exited combined) make martech the most established top 100 of any digital sector we’ve analysed except adtech, reflecting a market that has been building software and services for marketers since well before the post-2020 funding wave.
- The top 100 collectively raised £1.76b — 73% of the sector’s all-time total.
