The growth in company numbers was backed up by capital. London-based AI companies raised £5.50b across 755 funding rounds in 2025. That was the strongest year on record for both value and deal count.
The stage distribution shows a sector that is still emerging, even as its leaders mature. Seed-stage companies account for 58% of all London-based AI companies, and there was a record-breaking 1.08k foundations in 2025. Lots of new entrants plus large rounds for a few leaders is the classic profile of a sector that’s still being explored while early winners pull ahead.
The investor signal points the same way. Entrepreneurs First, a company builder that backs founders at the very earliest stage, was the most active investor by deal count, with 80 rounds.
Signals that converged: growth in company numbers, fundraising volume, stage distribution, and investor activity. For more on whether the momentum will hold, see Artificial Intelligence: Investment Bubble or Genuine Hypergrowth Market?

Example 2: a funding boom-and-bust pattern in UK fintech, 2021–2023
In 2021, UK fintech looked unstoppable: companies raised £5.35b across 416 funding rounds. 2022 was another strong year, though it fell short of 2021’s peak.
The turn came quickly, however. Equity investment into UK fintech fell to just £1.85b across 356 funding rounds in 2023, and has stayed at roughly that level since.
Signals that converged: record investment, then a sharp fall in total value while the number of rounds dropped far less (about 14%, against a roughly 65% fall in value). Average round size shrank from about £12.9m to £5.2m. Investors were still writing cheques, but much smaller ones.
Example 3: a sector decline pattern in blockchain after the 2022 peak
UK blockchain companies raised £722m over 91 fundraisings in 2022, the sector’s all-time high, riding the post-pandemic crypto wave.
Since then, investment has stayed below that peak, with £542m raised in 2025. The company base has kept growing: Beauhurst now tracks 644 active UK blockchain companies, up from 82 at the end of 2015. But the capital behind it has cooled.
This is a useful reminder that ‘decline’ rarely means collapse. More often, it’s a shift from hype to a smaller, steadier market. Two signals are worth watching:
- Funding falling while formations keep rising, which means more companies chasing less capital.
- Changes in which sub-sectors attract the remaining money, such as compliance tooling, tokenisation, or payments infrastructure versus consumer crypto.
Signals that converged: falling deal value after a peak, while the company base kept growing. Sub-sector rotation could be the next signal to watch.
Common pitfalls when using company data for trend prediction
Company data is powerful, but it’s not self-interpreting. These are the mistakes that most often turn a sharp analysis into a misleading one.
Confusing noise with signal
Early-stage sectors are volatile. A single £100m round can double a niche’s annual investment total, and a handful of incorporations can look like a surge from a low base.
Before calling a trend, check whether it holds across multiple quarters and isn’t driven by one or two outliers. Medians and deal counts are often more telling than totals.
Relying on one indicator
Funding alone can mislead, because capital follows hype as readily as substance. Formations alone can mislead too, since incorporating a company costs very little. Always cross-reference at least three signals before drawing a conclusion.
Survivorship bias
Sector reports built only on the companies still trading miss the churn. If you only study today’s successful players, every sector looks healthier than it is.
Include dissolved and dormant companies in your analysis. That shows you the true rate of attrition, and what failure looks like in this sector.
Retrospective narrative fitting
It’s tempting to start with the conclusion and go looking for supporting data. Company data is rich enough that you’ll usually find some.
Write down your hypothesis and the evidence that would disprove it before you look. Then report the signals that don’t fit as well as the ones that do.
Confusing sector migration with sector emergence
When companies tagged with a new buzzword multiply, it’s not always because new businesses are being created. Often, existing companies are relabelling themselves to ride a wave.
Check incorporation dates. If most of the ‘new’ sector’s companies are 10 years old, you’re seeing migration rather than emergence. Both matter, but they mean different things.
Ignoring geographic effects
A sector booming nationally may be flat in the region you care about, and vice versa. London often dominates UK totals, masking very different dynamics elsewhere. If your client, portfolio, or policy question is regional, cut the data regionally.
Under-weighting private company signals
Public company data is easier to access through earnings calls, annual reports, and analyst coverage. But the vast majority of UK companies are private, and that’s where sector shifts tend to start. An analysis built mainly on listed companies will be late to almost every trend that matters.
How Beauhurst helps predict industry trends
Bottom-up trend analysis is only as good as the data underneath it. Stitching together Companies House filings, funding announcements, news, hiring data, and patent records by hand is slow, inconsistent, and almost impossible to repeat every quarter. Beauhurst brings it all into one place.
Every UK private company in one dataset
Beauhurst provides complete coverage of every private company in the UK, plus Germany and Ireland. Your analysis starts from the whole population, not a sample or a survey panel, so you see the quiet incorporations and dissolutions as well as the headline-grabbers.
And with True Companies, multiple legal entities belonging to the same business are consolidated into a single profile. Group structures don’t inflate company counts or double-count financials.
Industry classification and buzzwords beyond SIC codes
Our industry classification covers millions of UK companies, combining machine learning with the judgement of our in-house data team.
Buzzwords are assigned by our researchers for high-growth companies, and by machine learning across the wider population. They capture emerging themes that SIC codes can’t see, such as generative AI, quantum, and defencetech.
Time-series data on every signal that matters
Formations, dissolutions, fundraisings, acquisitions, headcount, and ownership changes are all dated events in Beauhurst. Our UK fundraising data includes rounds that were never announced to the media (around 60% of all equity fundraisings), so your investment trend lines reflect what actually happened rather than only what was press-released.
Every signal on one company profile
Every company profile brings these signals together side by side:
- Financials and corporate structure
- Shareholders
- Grants and patents
- Accelerator attendance and high-growth list appearances
- Risk signals such as county court judgments (CCJs)
That makes cross-referencing (Step 5 of the framework) a matter of applying a filter.
Sector, sub-sector and buzzword filters
Combine industries, buzzwords, description keywords, location, and company stage to define your sector scope precisely, then save the search. Re-run it every quarter and you’ve got a consistent, repeatable baseline to track change against.
Cross-sector visibility for spotting migration
Because companies can carry multiple industry tags and buzzwords, you can see when established businesses start moving into new territory. You can also separate new entrants from incumbents relabelling themselves.
BeauhurstInsights: data-led sector reports and bespoke research
If you’d rather have the analysis done for you, BeauhurstInsights, our research service run by the Research & Consultancy team, uses Beauhurst data to produce bespoke research, thought leadership, and sector analysis.
Some teams want to run the analysis themselves, including strategy consultants, corporate development teams, and investors.
BeauhurstAdvise gives consultants and advisers the same data to work with directly, while BeauhurstInvest does the same for investors and corporate development teams.
Predicting industry trends using data
Industry trends don’t start in annual reports. They start with a cluster of incorporations, a run of seed rounds, a repeat acquirer, or a quiet rise in headcount. These events are visible in company data months or years before they reach the aggregate statistics.
Analysts who consistently use data can see the turn coming, and show the companies behind it.
