Top Tech Startups in Oxford, United Kingdom in 2026

Quantum computing has the potential to impact every area of human society for the better--our goal is to build computers to redefine industries like medicine, materials science, finance, artificial intelligence, machine learning, cryptography, and more.

Iterative Health is pioneering the use of artificial intelligence-based precision medicine in gastroenterology (GI), with the aim of helping to optimize clinical trials investigating treatment of inflammatory bowel disease (IBD). We use advanced machine learning and computer vision to interpret endoscopic images along with other types of data, helping clinicians to better assess patients with potential GI problems. This gives practitioners enhanced capabilities in the detection, annotation, disease scoring and treatment of GI related diseases. Iterative Health is initially applying these advances towards standardizing disease severity characterization for inflammatory bowel disease. Ultimately, the company aims to establish more meaningful endpoints to serve as better predictors of both therapeutic response and disease outcomes. The company is headquartered in Cambridge, Massachusetts.

Learning for software developers is broken. Available options are boring, time-consuming, not relevant to everyone, or require the company to take a big productivity hit. We've designed a fast, effective training solution for tech teams that avoids those pitfalls. Targeted Capability Training is: - Core to how an engineering team operates, not a fringe add-on or an after-thought. - Learning that aligns with business priorities and changes what the team is capable of. And we’re called Skiller Whale because … well, our love of puns knows no bounds. Our mission is to change what tech teams are capable of. We’ve found the most effective way to accomplish this is through challenging, realistic exercises that can be explored and tackled in our interactive teaching model. We strive to be intelligent, playful learners, like our Orca, Ada (yes, we love a Lovelace reference). These principles define who we are, not only as a company providing a product, but also as a group of people working together. We believe that diversity makes us stronger and are dedicated to building a company that represents society as a whole. We value marginalised people’s safety over privileged people’s comfort. We value honest and open communication, and we believe that in order to foster an environment that enables this, it’s important that our team feel included, recognised and like they can bring their full selves to work.

FairwAI is building real-time accountability infrastructure to detect bias in the moments that matter most. We’re solving one of the toughest challenges in tech: how to make fairness not just a principle but a system. From healthcare and hiring to hospitality and housing, bias shows up when people are most vulnerable. FairwAI turns those moments into measurable, actionable data—using AI, computer vision, and behavioral science to flag risks and enable institutional change before harm happens. We’re not a DEI tool. We’re compliance infrastructure for a new era—where safety, dignity, and fairness are non-negotiable. Our team includes engineers, policy thinkers, civil rights advocates, and public interest technologists from MIT, Harvard, Stanford, The UN, and beyond. We’re launching high-impact projects and building the backbone of ethical AI adoption across sectors. For interns & fellows, this is not a coffee-run experience. You’ll co-design tools, analyze live scenarios, and help shape the future of bias detection and remediation. Your work will be mentored, respected, and turned into real-world impact. If you care about fairness, ethics, and building tools that actually change lives—FairwAI is where your skills meet purpose. Join us. Let’s build the infrastructure fairness deserves.
