Series A Funding for Scale-Ups: What Guinness Ventures Looks For

Lisa Fox, Head of Co-Investment in
13 May 2026

Raising a Series A round is an important moment in a company’s development. It is usually the stage where the business is no longer experimental, but not yet fully scaled.

The product, service or technology is already in the market. Customers are already buying and coming back. The next challenge is turning that early demand into repeatable, sustainable growth, using capital received to increase significantly in revenue and scale.

This guide explains what Guinness Ventures looks for at Series A and scale-up stage, including commercial traction, repeatability, team capability, scalable economics and investor fit.

Series A funding: where proof becomes scale

At Guinness Ventures, we invest in high-growth UK companies through EIS and VCT strategies. We provide scale-up capital to businesses that have moved beyond early testing and are ready to expand both across the UK and internationally.

For us, Series A is the first true scaling round. It is the point where a company needs capital to build the team, strengthen operations, grow sales, expand distribution and prove that the model can work at greater scale.

We have written separately about what “Series A” means to us. In simple terms, we see it as the shift from proving demand to scaling execution.

What Guinness Ventures invests in

Guinness Ventures invests in UK-based companies at Series A and scale-up stage. We look for businesses with proven demand, strong commercial traction and the ambition to build durable companies.

A company we consider will usually have:

These are not rigid rules for every business or sector. A consumer brand, healthcare platform and B2B software company will each demonstrate traction differently. What matters is the quality of the evidence.

A good fit for Guinness Ventures is usually a company where the founder can explain three things clearly: why customers buy, why the business can scale and why this funding round matters now.

What we look for

We are not looking for perfection, but a decent working financial model helps. In practice, we focus on five areas:

Revenue growth matters, but we spend just as much time assessing the quality of that growth. A company growing through repeat purchases, renewals, efficient acquisition or strong distribution is very different from one relying on a small number of bespoke wins.

We also look closely at the team. Series A capital often changes the shape of a company. Founders may need to hire senior people, strengthen operations, improve reporting and make decisions through a more developed management structure. That transition is not always straightforward, so we want to understand how the team thinks, where it is strong and where support may be valuable.

The economics also need to make sense as the business scales. A company does not need to be profitable when we invest, but there should be a credible route to profitability and a clear understanding of what drives margin, cash generation and growth.

Finally, we want to understand why the company can win. That answer varies by business. It may come from brand, technology, data, regulation, distribution, customer relationships or sector expertise. But there needs to be a clear reason.

Where we invest

We are a generalist investor, but not an unfocused one. We back real-world businesses with proven commercial value, particularly across consumer, business services and healthcare.

The common thread is not sector. It is evidence. We want to see demand, quality of execution and the potential to build a valuable company.

You can see more examples on our Portfolio page.

How our process works

Founders are busy. Fundraising is rarely their only responsibility. We therefore try to be clear about fit, process and expectations from the outset.

A typical process begins with an initial meeting with one or two members of the investment team. We want to understand the business, market, team, funding requirement and growth plan.

This includes looking at commercial traction, financial performance, market position, use of funds and fit with our investment strategy. Our process is structured, but it is not designed to waste founders’ time. A good investment process should help both sides reach a clear answer.

Support beyond capital

The right Series A investor should bring more than capital.

Our network is an important part of what we offer founders. We work with investors, operators, advisers and sector specialists who can support portfolio companies as they scale.

We try to provide support where it is genuinely useful. The aim is not to add noise, but to help founders scale with greater confidence.

Is Guinness Ventures the right investor for you?

Guinness Ventures may be a good fit if you are a UK-based founder raising Series A or scale-up funding and your company has proven demand, typically £1m+ revenue, strong growth, a repeatable sales model and a credible route to profitability at scale.

We are less likely to be relevant if the business is still pre-revenue, still searching for product-market fit or unlikely to meet EIS or VCT eligibility requirements.

For the right business, we aim to be an evidence-led, straightforward and supportive investment partner.
