Big data is at the heart of the UK’s technology economy, underpinning everything from AI-driven drug discovery and financial analytics to climate monitoring and defence intelligence. Investment in the sector has accelerated dramatically in recent years, with £1.51b raised in 2025 alone — and 2026 is already on track to surpass that, with £1.68b raised in Q1 alone. Collectively, UK big data companies have now raised £8.05b in equity funding.
We’ve ranked the top 100 big data companies by total equity raised (all data sourced from the Beauhurst platform).
What is big data?
Big data refers to the collection, processing, and analysis of datasets that are too large or complex for traditional methods. Big data companies develop the infrastructure, platforms, and applications that enable organisations to extract insights from vast volumes of structured and unstructured data. Applications span financial services, healthcare and life sciences, defence and security, energy, retail, agriculture, and environmental monitoring.
The UK currently has 547 active big data companies, having grown 93% over the past decade (from 283 in 2015). While this growth rate is more moderate than some emerging sectors, it reflects the fact that big data is a more established category with deep roots in enterprise software and research.
Collectively, these companies have raised £8.05b in equity funding so far, with a remarkable £6.89b — over 85% of the total — secured since 2020 alone. This sharp acceleration reflects the explosion of AI and machine learning, which has massively increased demand for data infrastructure, annotation, and analytics. These companies employ an estimated 28,515 people and generate a combined turnover of £4.40b.
Key findings
- NScale, which develops AI data centre and GPU supercluster infrastructure, dominates the ranking with £2.62b raised — more than eight times the amount raised by second-placed Exscientia (£299.8m), an AI-driven drug discovery company based in Tayside. BenevolentAI (£253.0m), Matillion (£226.8m), and 9fin (£198.2m) complete the top five.
- London accounts for 58 of the top 100 companies. The South East follows with 11, and the East of England has six. Scotland is notably well represented, with companies in Tayside (Exscientia, IceRobotics) and the West of Scotland (Chemify, Aridhia). Northern Ireland also features four companies, including Cumulus Neuroscience and Analytics Engines.
- The top 100 are evenly split between Venture (37 companies) and Growth (36 companies) stages, with just seven Established businesses and nine already exited. This balance suggests a sector that is actively scaling — past the earliest stages but with significant headroom for further growth.
- The top 100 have collectively raised £5.93b — representing roughly 74% of all big data equity funding in the UK. However, NScale’s £2.62b alone accounts for 44% of the top 100 total, making this the most top-heavy distribution of any sector we’ve analysed.
