1. Rishi Khosla
Rishi Khosla, the co-founder of OakNorth, has redefined what it means to be a fintech entrepreneur in the UK.

OakNorth is a digital bank specializing in lending to scale-ups and mid-sized businesses, a segment often overlooked by traditional banks. Its core strength lies in its credit intelligence system, which helps analyze businesses with more nuance and accuracy than conventional banking models.
What makes Khosla stand out is his ability to quietly tackle the challenges that others have ignored. He isn’t focused on loud marketing campaigns or extravagant launches; instead, he has built a platform that bridges a major gap in the financial sector. In 2026, OakNorth is rolling out its advanced software solutions to overseas banks, ensuring global reach while maintaining its unique UK-driven edge.
Khosla’s disciplined vision makes him a leader worth following. By focusing on substance over noise, OakNorth has grown into a sustainable and innovative banking platform, proving that steady, thoughtful innovation often wins over short-term hype.
2. Victor Riparbelli
Victor Riparbelli, co-founder and CEO of Synthesia, is one of the most talked-about leaders in Europe’s AI space. While many jumped onto the AI wave, Victor and his team have been laying the groundwork for how AI-driven content can transform industries.

Instead of fueling panic about AI replacing jobs, Riparbelli’s vision is to empower creators with tools that make their work more efficient and impactful. Synthesia is now not only a technological success but also a pioneer in establishing standards for responsible AI deployment. Victor’s thoughtful approach and practical innovation make him a true role model in the AI space.
3. Tessa Clarke
Tessa Clarke is one of the few founders in the UK building technology with a direct impact on sustainability. Her app, OLIO, is designed to reduce food waste by connecting people and businesses with surplus food to those who can use it. Unlike many climate-focused startups that remain stuck in theory, OLIO has quickly grown into a practical solution adopted by communities worldwide.
In 2026, OLIO is expanding partnerships with businesses while introducing smarter food rescue tools, making it easier to prevent large quantities of food from going to waste. At its core, OLIO feels more like a social movement than just another app. It combines digital efficiency with grassroots community engagement, creating both environmental and social benefits.
What makes Tessa unique is her ability to balance big-picture climate goals with everyday usability. She believes that small, repeated actions by individuals can collectively bring about massive change. By keeping the platform simple and user-first, she has built not just an app but a habit-changing ecosystem. Clarke’s commitment to tackling waste while strengthening communities positions her as a rare founder who blends technology with meaningful impact.
4. Will Donnelly
Will Donnelly’s startup, Lottie, is transforming the elder care sector in the UK. Unlike many entrepreneurs who look to disrupt glamorous industries, Donnelly chose to fix a deeply personal and under-served challenge: finding quality care for the elderly. His journey began with personal experience and frustration, leading him to create a platform that simplifies the search for care homes and related services.
Over time, Lottie has evolved into a comprehensive healthtech company, offering in-home care tools, transparent pricing, user reviews, and well-being services for seniors. In 2026, Lottie is working directly with NHS trusts and private providers, bringing digital efficiency into a sector that has been painfully slow to adapt.
Donnelly’s greatest strength is his empathy-driven approach. He understands the emotional weight families carry when making care decisions, and he translates that into technology that is not only functional but also compassionate. By making elder care more accessible and transparent, Will Donnelly has proven that tech doesn’t have to be cold—it can be human-centered while still scaling into a major business.
5. Christopher Doman
Christopher Doman, co-founder and CTO of Cado Security, is tackling one of the toughest challenges in modern technology: cloud cybersecurity. In today’s digital-first environment, cyber threats have become more advanced, especially in cloud and hybrid environments.

Her work is proof that when deep science meets user-centered design, the result can change lives.
7. Alex Kendall
Alex Kendall, co-founder and CEO of Wayve, is tackling one of the most ambitious challenges in tech: autonomous vehicles.

Unlike traditional tools that often feel clunky and outdated, Humaans is designed with fast-scaling startups and global teams in mind. Its platform simplifies onboarding, compliance, and employee record management, all while integrating smoothly with a company’s existing tech stack.
In 2026, Humaans is expanding its reach beyond startups to mid-market and enterprise clients. Its API-first approach ensures that the software adapts to various needs without overwhelming users with unnecessary complexity. This flexibility makes it particularly valuable in the era of remote and hybrid work.
What sets Shelbaya apart is his product-first yet people-centered approach. He understands that HR is not just about managing forms but about fostering company culture and supporting employees. By building software that reduces friction rather than creating more, Shelbaya has created a tool that HR teams actually enjoy using. His vision shows how thoughtful design can transform even the most bureaucratic processes into seamless experiences.
