How We Classify Company Stages of Evolution

How the business world refers to company stages of evolution can be, at times, a little confusing.

Funding rounds are often referred to as ‘Series A’, ‘B’, ‘C’, etc. (mainly in the US), or ‘First Round’, ‘Second Round’, etc. (in the UK). It’s second nature to think of startup investment in this way, with companies, investors, and the press all relying on these terms.

However, despite their prominence, there are issues arising from traditional life cycle labels. This is due to inconsistent definitions and increasing round sizes. What these different series and round categories actually mean can vary hugely by sector, country, or investor type.

For instance, at the time of a ‘Series C’ fundraising, a three-year-old pharmaceuticals firm may still be in pre-clinical trials, whilst a software venture may be one of the biggest emerging companies in the world.

A cross-sectoral classification system is necessary. It allows you to conduct more informed analyses, and reliably identify key trends, areas of potential, or industries that are currently underfunded. But the current system lacks nuance.

The industry needs terminology that consistently, and impartially, classifies a company’s stage of evolution — so here’s our solution.

How do we track a company's stage of evolution?

Here at Beauhurst, we monitor every company in the UK and Germany, giving a comprehensive overview of both nations’ business economy.

As part of this, our Data team marks relevant companies with a life cycle stage as one of: Seed, Venture, Growth, Established, Exited, Zombie, or Dead. Similarly, the fundraisings held by businesses at these stages are classified to match.

Using our methodology, while a pharma company operating at the Seed-stage and a software company operating at the Growth-stage might both self-report a Series C round, we’d classify them as Seed-stage and Growth-stage rounds.

And the Beauhurst platform gives you a comprehensive timeline, showing how companies grew to each stage and the different types of funding and support they used along the way.

Defining our company life cycle stages

Life cycle stages are flexible, and a Venture-stage business in one industry may be a Growth-stage company in another. Still, here’s a quick rundown of each of the stages of evolution on the Beauhurst platform — and how we use them to classify UK and German companies.

Seed

A Seed-stage company is a young startup, with low employee count, valuation, and total equity investment raised. There may still be uncertainty as to whether its product or service has an adequate market, or it may be working to gain regulatory approval. The most common sources of funding for companies at the Seed-stage of growth are grant-awarding bodies, crowdfunding platforms, and angel investors.

While most Seed investments are under £1m, the biggest Seed-stage round in 2025 was secured by Fidra Energy. The battery energy storage firm secured a £445m deal in September 2025, with EIG Partners and the UK’s National Wealth Fund participating.

Venture

Venture-stage companies have developed their business models and technology over multiple years, typically securing investment and a valuation in the millions. They’ll have strong, growing revenue figures, and may be expanding their initial product range. Venture rounds typically involve private equity and VC funds, although they may still tap into crowdfunding too.

The most valuable Venture-stage investment of 2025 was for biotech firm Isomorphic Labs, which secured £449m to fund AI research and development for building its drug design engine and advance its program into clinical development.

Growth

Usually running for more than five years, Growth-stage companies are active in multiple locations, possess substantial revenues, and boast a large and growing headcount.

They may also be profitable, have a highly valuable patented technology, or have received funding and a valuation stretching into the millions.

Funding for Growth-stage companies is likely to come from venture capital firms, corporate venture funds, asset management companies, and traditional mezzanine lenders.

In 2025, NScale secured two of the top three largest Growth-stage investments, worth a combined £982m. The UK-based neocloud develops and builds AI data centres and GPU supercluster infrastructure, and has been identified as a key growth partner for building out AI infrastructure in the UK.

Established

An Established-stage company has been trading for 15+ years, or 5-15 years with a three-year consecutive profit of £5m+ or turnover of £20m+. These businesses usually have several offices and a widely-recognised brand. Funding at this stage is often deployed by corporates, private equity firms, banks and specialist debt funds, or major international investors.

The largest investment into a company at the Established-stage of growth in 2025 was The Ardonagh Group’s £1.82b deal, with participants including the Abu Dhabi Investment Authority (IDIA).

Exited

We assign an ‘Exited’ classification when a company is absorbed by another entity and no longer operates independently, normally via acquisition or reverse takeover.

For a high-profile example, look no further than DeepMind, which was acquired by Google in 2014 for £400m. The company was subsumed into Google as Google DeepMind and is therefore no longer an independent operator.

Exited profiles are still updated, however, as shown by DeepMind’s 2016 acquisition of Imperial College London’s medtech spinout, Hark.

Listed companies are usually still tracked at the Established-stage post-IPO, as they are still functionally autonomous.

Zombie

A zombie company is our name for businesses that have been neglected for a long time or are in a troubled financial state. Whilst the company is not ‘dead’, it doesn’t appear to be operating: the company’s website/social media shows prolonged, uncharacteristic neglect, or the company’s status on Companies House is troubled (i.e. in administration, liquidation or dissolution first gazette).

A down-round is not sufficient reason for a company to be classed in the Zombie-stage — though we would assign a Risk Signal — nor is a holding company that has stopped trading, provided that its subsidiaries are still operating as normal.

Dead

The Dead-stage of evolution is the point of no return. A company will reach this stage if one or more of the following conditions have been met: The company has stated it has definitively ceased all activity; its top parent company has been formally dissolved on Companies House; the company has relocated its primary location outside of the UK, or if it’s been stuck at the Zombie-stage for a minimum of six months.
