Frontier Health, a UK startup that builds AI tools for healthcare administration, has raised $16 million in a seed round led by some of Europe's better-known technology investors. The company makes a product called JUNO, which works alongside NHS admin staff to handle routine tasks that keep patients moving through care. Rachel Finegold founded the company in 2024. She spent years before that as healthcare lead at Palantir Technologies, working across more than 40 NHS Trusts, and built Frontier Health with a team that brings hands-on NHS experience together with applied AI engineering.
The NHS is carrying a large backlog of untreated patients. The hospital treatment waiting list hit a record of 7.7 million in September 2023 and has since fallen to around 7.1 million as of March 2026, but performance is still well short of official targets. The median waiting time for treatment is currently 11.9 weeks, compared to 7.2 weeks before the pandemic, and the government has set interim goals of 65% of patients treated within 18 weeks by March 2026, rising to 70% by March 2027. Behind many of the delays, though, is not just a lack of clinical staff. Missed follow-ups, results that go unacted on, and slow escalations all chip away at patient progress before a doctor or nurse is even part of the picture.
Atomico led the seed round, with firstminute capital and XYZ also participating. Frontier Health plans to use the money to expand JUNO into more NHS Trusts, add to the product's capabilities, and grow its team.
Much of the conversation around NHS pressure focuses on doctors and nurses. The administrative workforce gets less attention. These are the teams responsible for scheduling appointments, chasing results, tracking where patients are in a care pathway, and making sure nothing slips through the cracks. They are understaffed, using tools that have not been updated to match current demand, and working in an environment where non-clinical hiring is tightly restricted.
Standard automation software tends to be fragile. It relies on processes that have been mapped out in advance, and it breaks when anything changes. JUNO is designed differently. It works within the hospital systems already in place, navigating them the way a member of staff would. It completes routine administrative tasks, flags when something is falling behind, and escalates when a patient is at risk of not progressing as expected. Hospitals do not need to change their infrastructure to use it, and deployment can take a matter of weeks.
"Healthcare administration is at an inflection point. For too long, the systems and teams keeping patients moving have been asked to do more with less, and the consequences are visible across every NHS waiting list and performance metrics. Frontier Health's approach represents a genuine shift in what is possible, and JUNO's early results demonstrate the scale of the opportunity. The team's depth of NHS experience and proven execution make them uniquely placed to lead this category,"
Lina Wenner, Partner at firstminute capital
The bulk of the new capital will go toward rolling JUNO out across more NHS Trusts. Frontier Health will also continue developing the product and expanding its team. The company has run live deployments already and is now looking to bring that work to a broader set of hospitals dealing with similar administrative pressures.
Security and oversight are built into how JUNO operates. It runs entirely within an NHS Trust's own secure environment, with no data leaving that boundary and no elevated system access. Every step it takes is checked against expected conditions as it runs. If something does not match what it should, JUNO stops and brings the issue to a staff member. In healthcare, where small errors can affect patient care, that kind of auditability matters.
"Most enterprise AI is still looking for proof that it works in the real world. Frontier Health already has it - inside one of the most complex and demanding environments on the planet. JUNO is already reducing the delays and backlogs that have a direct impact on patient care, and delivering meaningful results across the NHS tells you something about the strength of the team and the product. We think this is the beginning of a significant new category in healthcare infrastructure,"
Andreas Helbig, Partner at Atomico
Frontier Health was founded in 2024. Finegold's years inside NHS hospitals at Palantir gave her a close view of where the system was failing, not because staff were not doing their jobs, but because the tools available to them had not kept up with the volume of work being asked of them. That became the foundation for the company.
JUNO acts as a digital teammate for NHS admin teams. It works across existing systems to take care of booking, validation, patient tracking, follow-up, and communications. Staff do not need to change how they work to use it. They stay in control of decisions, escalations, and oversight throughout, and every action the system takes is logged and reviewable.
"I spent years inside the NHS across more than 40 hospitals, watching brilliant, dedicated people drown in process. Not because they weren't good enough, but because the tools around them hadn't kept pace with the demand placed on them. The admin that should be keeping patients moving was becoming the thing that slowed everything down. That is a solvable problem. JUNO exists to solve it."

At East Sussex Healthcare NHS Trust, the results from an early deployment showed 221 staff days saved over eight weeks, and a 22% reduction in the median time patients spent moving through their care pathway. The Trust has since extended JUNO across more of its wards.
The round was led by Atomico, a European venture capital firm founded by Skype co-founder Niklas Zennström, whose portfolio includes Klarna, Stripe, and DeepL. firstminute capital, a London seed fund that made early investments in Wayve, Mistral, and Granola, also took part, as did XYZ Venture Capital, an early-stage firm founded by Ross Fubini in San Francisco with a background in public sector and defense technology.
