The purchase of medical diagnostics firm Blackford Analysis by Bayer is one of the best examples of how Scotland’s angel network works – but there are many others

Bayer, the German life science leviathan, global leader in health and nutrition, completed the acquisition of an innovative Edinburgh spin-out skilfully deploying artificial intelligence in February 2023.

Blackford Analysis, now a global provider of AI platforms for radiology and other medical diagnostics, had been supported and encouraged by a group of Scottish angel investors, individuals in syndicates largely unknown by the majority of Scots.

Blackford, set up at the Royal Observatory on Blackford Hill, in Edinburgh, and run by University of Edinburgh academic Ben Panter, adapted its star-gazing algorithm to identify tumours in cancer patients, and built an innovative platform deploying AI in the rapidly expanding sphere of healthcare.  

Bayer paid an initial upfront fee of about €46m (£39m) to acquire Blackford. Further amounts of up to about €54m (£46m) are payable upon hitting predefined research and development milestones.  

“The purchase price mainly pertained to goodwill, which in turn largely reflected the anticipated innovation potential and amounted to around €68m (£59m) based on the purchase price allocation,” stated Bayer. In addition, an amount of about £8.6m was recognised for patents and technologies, some £1.7m for other assets, and approximately £6m for liabilities. 

It is a feather in the cap — and a welcome pay-day — for Scotland’s angel investors who supported the growth of Blackford for ten years. It is also one of the best examples of how Scotland’s angel network has developed, but it’s not the only one.

In 1992, two unlikely business characters met in a Colinton restaurant and decided to combine the spoils of their success to invest in emerging Scottish companies.

One had been the managing director of Christian Salvesen, a pillar of Scotland’s listed company sector, the other had created a ground-breaking estate agency which challenged the legal professions monopoly and has changed the market place.

What Mike Rutterford and Barry Sealey, who passed away in 2024, set in train is one of Scotland’s greatest success stories. It was a risky exercise: and it still is. 

 The recent fall into administration of Glasgow-based M Squared Lasers, a photonic and quantum developer – initially supported by angel investors and then, as the company scaled, institutional money from the likes of Santander and, more recently, the Scottish National Investment Bank, which is expected to take a hit of over £20m – shows the precarious nature of innovation, where nothing is ever guaranteed.

The bank provided M Squared Lasers with £34m in a mix of debt and equity funding. This is the kind of risk that is often not fully appreciated. 

Bayer has paid around £100m for this Edinburgh start-up. It is a feather in the cap for Scotland’s angel investors

Rutterford and Sealey created the Archangels Informal Investment Syndicate, in Edinburgh. It has spawned, in the intervening 33 years, many more angel investment organisations across the country [see WHO ARE THE ANGELS SUPPORTING? below or page 27 in the Autumn 2025 issue of The Business magazine, distributed with The Sunday Times Scotland]. Rutterford and Sealey were among the individuals investing in Blackford’s technology. 

By 2011, when the Organisation for Economic Co-operation and Development (OECD)  examined Scotland’s angel network, the World Bank went on to describe it as ‘The Scottish model’, leading to admiration and copy-cat syndicates around the globe. Furthermore, the angel syndicates in Scotland have pumped several hundred million into scores of Scottish start-ups, providing the risky capital at the earliest stage in a company’s formation.

These syndicates are made up of high-net worth individuals who have done well and want to put something back to encourage innovation and endeavour, with the possibility of making a return.

The number of angel investments in Scotland fell slightly to 91 from 94 in 2023-24, but the value of private capital committed increased from £100.6m to £106.4m, reflecting an increasing average deal size. Public sector co-investment provided a further £25.6m.

David Ovens and Niki McKenzie, joint managing directors of Archangels. The organisation retains its original ethos of supporting Scottish companies

Niki McKenzie, the joint managing director of Archangels, has been with the organisation for 15 years. She says that while Archangels has retained its original ethos of supporting Scottish companies, it has changed substantially from those earlier times when Rutterford and Sealey and their colleagues took a punt on a idea.

Today, like most angel syndicates, there is more data-driven analysis and engagement with the key leadership teams to drive growth.

The wider economic impact for Scotland is just as important as the financial returns for the investor

– David Grahame

In August, Reactec, one of Archangels’ long-standing investments, was sold to Ideagen for an undisclosed fee [see page 29 of The Business magazine] which brought a welcome pay-out for members. It is an example of patient long-term investment leading to finding the right future partner for scalable growth.

“It is a very changed market. Significantly so,” says McKenzie. “The big change is the ability of companies to scale, and the ambition of the founders who want to scale further. In the past, we would be putting £2m to £3m into something, and then selling it for, perhaps, £10m to £15m. The ambition now is that the founders want to go further.”

In those early years, Scotland’s angel investing ecosystem was constrained in its ability to scale-up because of the remoteness from London and New York and the lack of an ecosystem of investment support.

The creation of the Scottish Co-Investment Fund, given regulatory approval from the European Union and supported by Scottish Enterprise, has been a vital step-change with the public sector mirroring the investment of the angel groups, which doubles the amounts being put into innovative businesses. This is well established and works extremely well.

“Now, post-Covid, there are lots of co-investors coming into Scotland. People realised that co-investors in London could get on a Zoom call and hear about interesting start-ups north of the Border,” says McKenzie.

According to figures compiled by Young Company Finance, in 2022 there were 61 new investors in Scotland, with a further 65 the following year, and 73 new investors in 2024: this is nearly 200 pots of new money scouring technology and scientific innovation in Scotland, primarily emerging from the main universities.

“The angel syndicates have been consistent throughout. At Archangels, we’ve been very steady with our membership and slightly increasing what it has done. What we are able to do is bring in the co-investor which has increased the pool of funds for investing,” she says.

While this includes public sector money – the British Business Bank has stepped in with its regional programme along with the Scottish National Investment Bank – the majority comes from private individuals’ funds, venture capital and venture capital trusts.

“It is the private, commercial money that is really coming in and driving the change in quantum levels of funding,” says McKenzie.

This, in turn, brings in fresh skills sets and expertise, diversity in the business and at board level, but more widely it is increasing the reach of Scotland to pull in the money it has desperately needed to turn innovation with commercial opportunity into scalable companies.

One long-running complaint has been that Scotland’s start-ups either fall by the wayside or cash in their chips with a sale, which means losing vital growth in Scotland. Our national unicorn count [a technology company with a valuation of £1bn] is pretty low, yet Britain has created 178 unicorns since 2000, more than Germany, France and Switzerland combined.

This remains an infernal problem, but what is encouraging is that venture capital groups based in London are looking to Scotland for novel companies and for value.

Typically, venture capitalists who follow the angels look for less risk, and have a shorter timeframe for investing, between three to five years before exiting. 

“In the past, start-up companies were told you need to get your money locally. But we’re now saying look widely for strategic partners. Look to London and elsewhere, companies should broaden their horizons and make the most of the money flow.”

Increasingly, the VCT (venture capital trust) players, such as Mercia, Maven, Foresight and Blackfinch, are suitable tax-efficient co-investors alongside Scotland’s angel groups.

The life sciences sector in
Scotland has faced a rocky time in the post-Covid world. Britain’s £108bn life sciences industry, which employs more than 300,000 people in high value jobs, is a national crown jewel.

But AstraZeneca, Britain’s most valuable listed company, is considering moving its primary listing to New York. Sir Pascal Soriot has voiced his frustration at the National Health Service’s poor track record in supporting UK drug discovery.

Last year, AstraZeneca scrapped a £450m expansion of its vaccine plant in Liverpool. At the root of this is R&D (research and development) and vital phase III clinical trials of new medicines.

“After Covid there has been a new focus on what big pharma is going to do next. Therapeutics is more difficult, Brexit has made it hard from a regulatory point of view, so there’s been a dip. Although our Archangels companies are not doing therapeutics and the actual drug discovery, the services, the diagnostic tools and devices which sit around this have all been impacted,” says McKenzie.

However, in Scotland there is still outstanding technology and generative AI and machine learning is part of this and a big topic across almost everything. Read more about the tech sector as a ‘a real hotspot’ in deals market with the Summer Deals in Focus published in The Business magazine online.

David Ovens, McKenzie’s colleague at Archangels, says: “We’re sticking to our knitting in trying to pick deep tech that is difficult to copy which is heavily patented. We’re looking for ‘proof points’ or real value with modest amounts of money, of around £5m, so that you can get a valuation or an exit.

“There are definitely lots of interesting Scottish companies around it, in the life sciences sphere. It’s a question of being able to ride this cycle of what big pharma is doing. There are definitely problems to be solved. We’ve got Cytomos in our portfolio doing really smart cell-analysis and ground-breaking work with large blue chips,” he adds.

Archangels is also supporting the team at 1nhaler, a single dose inhalation device for targeted treatments.  “There’s a great team in place and this is exactly the kind of business that we want to help grow and succeed,” says McKenzie.

David Grahame is the doyen of Scotland’s angel investment groups. He was a discreet lieutenant among the founders of LINC Scotland in 1993, now Angel Capital Scotland, and is stepping back while Margaret Morton becomes the organisation’s first CEO.

He says Brexit was a severe blow, explaining that the European Union’s regional development funds allowed LINC to assist the angel groups with early administration and with network support. 

Grahame believes that business failure is a core part of the process. He says worldwide, half of all angel groups make no money. 

“It’s the 80:20 rule of failure to success. People, including the press, spot the failures all along the way but years later you might get a good exit such as Reactec,” he says.

“The wider economic impact for Scotland is just as important as the financial returns for the investor. A lot of angel investors do take massive losses, yet if you fund a company and it gets going and it employs 20 people and it falls over five years later, that is still a positive economic impact.”

We’ve been involved with a large number of angel deals – we’ve changed and adapted as these firms have matured

– Stuart Hendry

Stuart Hendry, founder and partner with MBM Commercial, has had a front row seat as a legal adviser watching the angels’ growth.

His company celebrates 20 years supporting entrepreneurship in the coming weeks. His major concern is that while there is more than enough start-up funding, it is the Series A and Series B money for scaling up ambitious companies that was missing.

Meantime, his company pioneered pro forma legal documents and the use of templates to keep the cost of deals at a modest level for young companies. 

“However, things have developed. A seed deal might be for £1m or £2m and you tend to find lawyers on both sides of the deal. Increasingly, clients want an efficient service and to get the deal done,” he says. 

He says young companies today are far better educated by Scotland’s accelerators and investment incubators, and by the accumulated knowledge of Angel Capital Scotland.

 “MBM, which now has a US arm dealing with US investors, has grown with the companies over the years. We’ve been involved with a large number of angel deals and then financing rounds – we’ve changed and adapted as these firms have matured,” he says.

Scotland’s angel success story remains known only to those directly involved and the advisers – but it remains a unique part of Scotland’s entrepreneurial success.
