Finding investment as a deep tech business can be a difficult and arduous task. Whilst raising capital is rarely a walk in the park, funding for deep tech can be notoriously challenging because of its complex nature. Founders can struggle to communicate a real understanding of their startup, which can leave investors feeling unsure about its true potential.

There’s no shortage of fantastic deep tech businesses here in the South West – take a look at our one’s to watch article for a flavour of the pioneering startups, scaleups and unicorns in the region –  but the investment is needed to match, sustain and expand their work.

To help combat this, we’ve compiled a list of the five most active and well-known deep tech investors in the UK, as well as a shoutout to the newly created South West deep tech EIS Seed Fund, Science Creates Ventures (SCV). These firms and networks have a long track of successful investments in highly innovative business; if you are a founder looking for capital, they are definitely worth checking out!

Amadeus Capital

Amadeus Capital is a well-established Venture Capital company that was founded in 1993. Headquartered in Cambridge, the firm has been actively investing in deep tech companies across the UK for many years and it should be the first stop for founders looking for capital.

They are well-known for making early bets on deep tech startups. In the past; Amadeus Capital has shown great interest in early-stage UK businesses that are involved in artificial intelligence, cybersecurity, quantum technologies, and machine learning.

Amadeus is nearly always looking for opportunities to invest in companies that are developing new technologies, as well as supporting them in the commercialisation process. From examining their trends, Amadeus usually invests in early stages (seed and Series A) for UK businesses, whereas when it comes to European and American companies they tend to invest in later stages.

Some of their most notable exits are NASDAQ listed ForeScout, OneDrum (acquired by Microsoft) and VocalIQ (acquired by Apple). In 2020 and so far in 2021, Amadeus has invested over £292m, including £116m in the Bristol-based unicorn Graphcore, and other 19 companies such as QUIBIM, Nu Quantum, and V7

The key things Amadeus Capital looks for in a company looking for funding are: having a great team, a competitive edge, meeting under-served customer needs, operating in big markets and great scalability and global potential. Founders who think meet all requirements are welcome to submit a proposal via their official website.

Bloc Ventures

Bloc Ventures was founded in 2013 and is headquartered in London but with a team spread across the UK. The team is made up of former engineers, entrepreneurs and corporate venture investors from ARM and Vodafone, where their investments led to a number of large deep tech exits such as Affirmed Networks (acquired by Microsoft) and Thundersoft (IPO). Bloc’s investment focus is entirely on deep tech and they typically focus on companies building complex technology which sits deep in the stack, rather than consumer products.

Given the team’s experience working in telecoms, communications and semiconductors, it’s no surprise to see these areas feature heavily in their portfolio such as University of Southampton spin-out AccelerComm, which raised £5.8m in Series A funding last year, led by IQ Capital with Bloc leading the Seed round. Their four core focus areas are cloud computing (they are the lead investor in Bristol-based YellowDog), data science (they recently invested in Mindtrace), connectivity (Bloc is lead backer and it’s co-founder David Leftley is Chairman of Zeetta Networks) and security (such as Tether, a company which Bloc has backed to bring legacy video surveillance to the cloud).

The investment team at Bloc all have engineering degrees and experience in operational, technology focused roles. That means they’re able to be a supportive investor on many fronts: technology, product and fundraising. In addition, with two former VPs from ARM and the former VC team from Vodafone, they have strong connections to global technology giants such as Apple, Amazon, Facebook and Google. This provides the portfolio with vital commercial introductions and potential hiring solutions as they grow and begin to reach product market fit (a crucial stage in the deep tech journey).

Bloc’s most mature investment is in EVRYTHNG, a late stage company connecting physical products to the internet on behalf of some of the world’s largest brands, such as CocaCola, Ralph Lauren and Loreal. Another of it’s later stage portfolio companies is Marmalade, a game studio (not deep tech) which started out as a game production engine (deep tech) but pivoted and today produces the Monopoly game on behalf of Hasbro.

In recent times, Bloc has expanded its team (four people hired in the last 12 months) and that would indicate they’re looking to increase the portfolio. They typically invest between Seed and Series A rounds in deep tech companies typically throughout the UK but also across Europe (they backed Belgium-based Pharrowtech in 2019). You can reach out to Bloc directly via their website.

Cambridge Angels 

Cambridge Angels is an Angel Network that was founded in 2001 and is a leading UK business angel network with international connections. As the name suggests, it’s headquartered in Cambridge and its members comprise successful entrepreneurs as well as business experts. 

At Cambridge Angels, they are actively engaging in mentoring and investing in innovative entrepreneurial teams and their ideas, to achieve returns and help realise their full potential. They invest in a wide range of startups and scale-up businesses but focus mainly on technology, internet, software, and hardware.

IQ Capital 

IQ Capital has great experience at investing in deep tech companies and has been supporting businesses since its founding in 2003. Once again, IQ Capital is headquartered in Cambridge – investment firms in the area are deeply interested in the deep tech scene! 

Since its founding, IQ Capital has been investing in Seed and early-stage deep tech companies, therefore they have a very good understanding of how tech companies operate and know exactly how to support growing tech businesses. Predominantly IQ Capital invests in startups involved in artificial intelligence, machine learning, data science, and disruptive algorithms. They look for businesses that have developed or are developing new hard-to-replicate technology with founders teams that are highly motivated and capable to cope with the challenge

Force Over Mass

Force Over Mass was founded in 2013 and it’s headquartered in London. Force Over Mass doesn’t solely invest in deep tech, however, they’ve shown great interest in businesses in the field and have been busy investing activity in the past year.

Force Over Mass focuses on B2B technology innovation (Industry 4.0, Artificial Intelligence, Fintech) in Europe and the UK. They invest in companies that combine transformational technology with strong business models.

Martlet Capital

Martlet Capital is an early-stage investor based in Cambridge, providing patient capital to deep technology and life science startups with high growth potential. The firm was founded in 2011 and, although it mainly looks for early-stage startups, recent investment activity shows that they also tend to invest well over £1m on certain occasions.

The firm provides early-stage patient capital and support. They thrive to help founders and ventures grow by providing added value beyond money. This may include helping companies build teams and boards, advising on strategy, connections to technical experts, customers and investors, as well as being part of the community of their portfolio companies. Martlet Capital always co-invests alongside other VCs, angels or seed funds. 

In their own words “We seek early-stage ventures that can demonstrate their potential for rapid growth and will usually possess a strong defensible position with respect to their technology, intellectual property and products. We typically focus on pre-seed, such as university spin outs, and seed stage ventures that have completed a proof of concept and explored demonstrable commercial demand for the technology under development”.

Recently Martlet has invested over £20m spread over 8 UK businesses, such as Cambridge GaN Devices (£6.95m), Flusso (£4.53m) and Nu Quantum (£2.1m). Companies that meet their criteria are welcome to submit their investment proposal via their website.

Bonus: Science Creates Ventures

Evidently, Cambridge appears to be one of the dominating regions in deep tech investing, with 4 out of 5 in our list being headquartered in the region, so its excellent news for the South West that the region’s first and only deep tech fund, Science Creates Ventures (SCV), has now come into fruition

Science Creates saw a gap in the market, as well as a crucial need, for dedicated deep tech startup support in the South West. Created specifically for science and engineering startups, SCV invests from £250k to £1.5m and is focused on pre-seed and seed-stage companies – if it sounds like your business fits the bill, don’t hesitate to get in touch.

When talking about why funds like SCV are so important, CEO, founder and general partner of SCV Dr Harry Destecroix, says, “Innovative companies need a lot of support and they need investors that understand their businesses. We’re here to help more great companies emerge.”

Its inaugural investment was made recently in biotech startup CytoSeek, who is developing new cell therapies to treat solid tumours in cancer patients.

Speaking of the investment, Harry tells us, “Historically, biotech companies in the South West have struggled to raise sufficient capital, even though the technology and research has been there. While founding my own start-up, Ziylo, I became aware of just how many discoveries failed to emerge from the lab in Bristol alone. No matter the quality of the research and discovery, the right ecosystem is fundamental if we are going to transform the 90% failure rate into an 88% success rate for companies, and create many more successful ventures.

“It’s why we launched SCV; to find great technologies, syndicate with other world-class investors and get sufficient capital to help companies accelerate their technologies to market.”
