Scale Up 50 Web Graphic

In the technology sector, every year is a new era – each one defined by the relentless pursuit of innovation and growth. To celebrate the industry and those within it, last year saw us launch the first-ever Capsule Scale-Up 50 list. The response from the companies listed, as well as investors and the global tech community, surpassed all expectations.

Ahead of yet another transformative year, we’re excited to present our second edition. Supported by Cooper Parry and HSBC Innovation Banking, this year’s list highlights the leaders in the tech industry and acknowledges the remarkable success of the tech scale-up and investment market in the last 12 months. So, what can you expect this time around?

Back in 2022, experts anticipated a breakthrough for generative AI – and now, seeing AI scale-ups take the lead, it’s clear that their predictions were accurate. Other industries dominating the list include health and life sciences and FinTech – demonstrating the diverse nature of innovation in this space. The strides made in health and life sciences underscore a growing commitment to a better standard of living, while the FinTech sector’s prominence answers a need for greater convenience, accessibility, and transparency across financial services.

It was great to see some familiar faces pop up in the list, including former Revolut Product Lead Bogdan Uzbekov and Songkick co-founder Michelle You, plus more than a few Capsule clients – you know who you are. We’re also celebrating the rise of more female founders in the tech space such as GetHarley CEO Charmaine Chow, as well as some staggering funding raises – with one pot totalling £200 million (Field, we’re looking at you).

Collectively, the companies featured on this list raised a commendable £1.5 billion of funding in 2023 alone – a testament to their strategic acumen, inventive approaches, and the trust placed in them by leading investors including Balderton, Index Ventures, Octopus Ventures and MMC Ventures. As these businesses continue to forge ahead, this financial backing not only fuels their existing operations – but also drives them towards a future marked by expansion, groundbreaking initiatives, and sustained success.

Ready to discover the influential players redefining their respective industries? Let’s get stuck in…

Searching for a new job in tech often involves an endless stream of applications, rejections, and follow-ups – while for employers, one open role could mean sifting through hundreds of CVs, and the right match isn’t always guaranteed. hackajob understands that, which is why its unique hiring platform flips job searching on its head. Candidates post their requirements online and companies pitch to them, instead of the other way around. And clearly, something is working – in May 2023, the firm raised an impressive $25 million in its Series B funding round led by Volition Capital to help accelerate US growth. Proud to call this one a Capsule client!


Mental health care is a vital, but often sidelined, area of health maintenance. That’s why HelloSelf aims to make clinical therapy a more accessible option for everyone – its innovative digital platform uses AI to match patients with the right therapists and calculates the impact of these recommendations. It’s no surprise that the HealthTech is backed by Octopus Ventures, who led it through a successful $20 million Series B funding round in March 2023 – the sum of which will be put towards expanding its network of therapists, partners, and members across the UK and Europe.

Isometric helps companies move from low quality, temporary carbon offsets to high-quality, trustworthy, carbon removal credits they can use to meet their climate commitments. The brainchild of serial entrepreneur Eamon Jubbawy (who previously co-founded Onfido, Safi and Sequence, which featured in last year’s Scale-Up 50), Isometric raised $25 million in seed funding in July 2023 from Lowercarbon Capital, Plural, and multiple angel investors including Niklas Zennström of Skype fame.


Capsule Scale Up 50 2024 Featured Images Kroo V2

In a world where banking often sticks to the status quo, Kroo is challenging the norm. The digital bank bagged 150,000 customers over the last 12 months, with most flocking to its trailblazing current account product with an unusually high interest rate. And that’s not all – beyond offering customers an amazing deal, Kroo has set out to redefine the essence of banking, promising a positive impact on the world. It’s little wonder that it was able to raise £2 million in crowdfunding in November 2023.

Lindus Health

The clinical trial process is fragmented – that’s according to Lindus Health, the digital health startup aiming to piece it back together. By handling the end-to-end execution of clinical studies – including design, patient recruitment, clinical data capture, and project management – Lindus can deliver trials three times faster than the industry standard. So it’s no surprise that it managed to secure $18 million of Series A funding in August 2023, led by Stockholm-based Creandum (historic backers of Klarna, Spotify and Depop) and supported by PayPal co-founder Peter Thiel.


Digital collaboration is vital for productivity and innovation. But in the era of collaborative SaaS, how can organisations ensure their sensitive data is kept secure?

Together with their partners, they support over a million people and take workplace health from 'meh maybe' to 'yeah baby'.


Phasecraft has cracked the code for innovation. Powered by a team of world-leading quantum scientists and engineers, its vision is a future where once-in-a-lifetime discoveries happen every day. And as a joint spinout of University College London and the University of Bristol, it’s no wonder that the company closed a £13 million Series A in August 2023 led by Silicon Valley-based DeepTech VC Playground Global (with support from AlbionVC and Episode 1). The capital will help continue the team’s work developing quantum algorithms for real-world applications – crucially, the discovery of new materials to aid the global transition to clean energy.

Capsule Scale Up 50 2024 Featured Images Raylo V2

Raylo is making the circular economy a reality. Its online platform allows consumers to lease new gadgets like phones, tablets, and laptops at affordable subscription-based prices. What further sets Raylo apart, though, is its commitment to inclusivity – with no credit loan or formal agreement required, it makes top-notch technology accessible to a broader audience.

The B Corp’s latest £5.2 million raise in September 2023 came from the likes of Macquarie and Channel 4 Ventures. The funds join a £110 million debt financing facility from NatWest and growth investor Quilam Capital, positioning Raylo for an exciting phase of expansion. This substantial capital will help it offer an even wider range of gadgets, like e-bikes, while continuing to invest in its existing tech – including AI to assess risk for each sale. As a client of ours, we eagerly anticipate Raylo’s next developments and the positive impact this forward-thinking firm will have on the tech leasing landscape.


Waste management doesn’t have to be rubbish – that’s Recycleye’s vision.

CEO Richard and his team have big plans to capitalise on strong momentum and plan to use the new funding to fuel international expansion.


Carbon emissions are one of the largest challenges we face as a planet. We have less than a decade left to make urgent reductions. Supercritical's mission is to remove carbon from the air by providing access to high-quality, durable carbon removal credits via its marketplace. Conventional avoidance offsets work by paying others not to emit, leaving the emitted carbon in the air. Carbon removal actually removes carbon from the air, meaning the same amount of carbon emitted is removed. In June 2023, Supercritical closed a $13 million Series A funding round led by Lightspeed Venture Partners. It’s safe to say co-founder Michelle You knows how to make a hit – she previously co-founded Songkick, the concert-booking platform that was sold to Warner Music Group in 2017.


Capsule Scale Up 50 2024 Featured Images Synthesia

A self-proclaimed leader in the AI video generation space, Synthesia is another industry heavyweight.

Created by trade experts for trade experts, Traydstream’s automated compliance and trade document-checking platform reduces risks and boosts profitability for its customers.

With live global client mandates already implemented including some of the biggest names in banking - Citi Bank, Deutsche Bank, Standard Bank, and Mitsui it’s no surprise that the FinTech closed out its September 2023 funding round with a $21 million Series B investment from two highly prestigious growth equity funds - from Pivot Investment Partners and e& capital.


Short-term cash investing should be easy and secure, which is why TreasurySpring has crafted a handy platform that does the hard work of connecting investors to a broad selection of the best risk-adjusted cash investment options across multiple currencies and tenors.

Imagine if your own body could identify, target, and eradicate tumours. Well, thanks to Cambridge spin-out T-Therapeutics’ revolutionary technology, this once far-off idea could soon become a reality. By harnessing the natural power of T cells, the BioTech has already made groundbreaking advances in the treatment of cancers as well as other inflammatory disorders. And having recently secured £48 million in Series A funding to expand its medicine pipeline, its treatments could soon be available to clinical cancer patients. Backed by Sofinnova Partners and F-Prime Capital among others, and led by serial entrepreneur (and two-time unicorn maker), Dr Allan Bradley, we’d say it's in good hands.


Capsule Scale Up 50 2024 Featured Images Tympa Health V2

Listen up! A better future for ear and hearing healthcare is coming, trailblazed by TympaHealth. Launched in 2017, the company set out to create the world’s first all-in-one hearing assessment platform, designed to deliver diagnoses and accelerate treatment within a single 30-minute appointment.

Notably, TympaHealth has managed to bring on-the-ground care to remote locations where ear and hearing care is otherwise unavailable – and having raised $23 million in its most recent funding round (led by Octopus Ventures, with participation from Dara Capital and Rezayat Investments), we can hear a bright future calling.


For co-founders Ruth Faram and Benjamina Bollag, the future of meat production doesn’t have to be unsustainable – at least, not if Uncommon has anything to do with it. Formerly HigherSteaks, the Cambridge-based life sciences company is using cell technology to revolutionise global food production and radically accelerate the availability of lab-grown meat. Powered by a team of industry-leading scientists, it has already had success creating products like bacon and pork belly – with more tasty dishes on the horizon, thanks to the company’s recent capital injection of $30 million in Series A funding led by Balderton Capital and Lowercarbon Capital.


Content moderation is a major concern for social media companies, which is why AI technology like Unitary is more vital than ever. Led by co-founder and CEO Sasha Haco, Unitary’s AI is able to comb through over three billion images every day, identifying and flagging harmful content the same way a human would. In March 2023, the firm was able to secure additional seed funding of $8 million led by Ian Hogarth, former CEO of Songkick and currently the chair of the AI Safety Institute to seal future partnerships and expand its team. Just five months later, it closed its Series A at $15 million led by Creandum, amid plans to launch across multiple languages and geographies.
