Top Tech Startups in London, United Kingdom in 2026

People follow experts they trust. But most of the value in those relationships is never realised. The demand is there, in the DMs, the comments, the "quick questions", but real answers happen one conversation at a time. Reach scales to millions. Judgement happens one conversation at a time. TWINii closes that gap. Each expert has their own TWINii: an AI version of them that their audience can talk to live, by voice or chat. It is built only from the expert's own material, shaped by their perspective, and fully owned and controlled by them. Audiences get a clear answer from someone they trust, applied to their situation, instantly, plus a recap and a practical next step. We are live on iOS and Android with a founding cohort of hand-picked experts across business, health, finance, coaching, faith and more. Experts keep ownership of their voice, knowledge and boundaries, and earn from every conversation their TWINii has. The shift is from search to ask. The behaviour is already here. We are building the layer that structures it. Note: This is the long-form. Trim to fit the field. Built from deck slides 1 to 7 and the expert narrative. We are a small, senior team building a new category: trusted expertise, on demand, owned by the experts themselves. Mobile-first, voice-led, live in market, and moving fast. You will work directly with the people setting product and strategy, ship to real users weekly, and own meaningful surface area from day one. What we care about: trust by design, expert ownership and consent, and building something people actually rely on rather than another engagement trap.

Reformly is a fast-growing DTC home Pilates brand operating across e-commerce and mobile. In our first 10 months, we generated over $4M in sales and built an app with 3,000+ active subscriptions. Our core audience is middle-aged women who want to feel stronger, healthier, and more confident, but often struggle with consistency. We help solve that by combining a physical Pilates board sold internationally with a mobile app that offers workouts, structure, and community. We are building more than a product. We are building a brand and ecosystem that helps women create a fitness routine they can actually stick to. Our mission is to help women become the best version of themselves. Our team is young, ambitious, and moves fast. We are not looking for people who want to coast, play it safe, or settle for “good enough.” We want people who care deeply about doing great work, want to achieve greatness in their career, and genuinely believe in what we are building. At Reformly, there is a lot of room for growth, ownership, and speed. We value initiative, decisiveness, and learning through action. We would rather make the wrong decision with conviction, learn fast, and improve, than make the right decision too slowly and without courage. If you want real responsibility, a steep learning curve, and the chance to help build something meaningful at speed, you’ll feel at home here.

We’re building a modern way for people across countries to discover meaningful connections, whether they’re looking for dating, friendship or marriage. The platform combines detailed profile and discovery filters with Smart Match, which lets users describe the kind of person they’re looking for in natural language. Privacy and safety are central to the product, with features including photo privacy controls, phone and identity verification, blocking and reporting, and profile visibility controls. NRI Dating is available on the web and Android, with iOS also developed as part of the platform. We’re continuously improving the product across discovery, matching, messaging, privacy and the overall user experience. We’re a small, hands-on team, so people who work with us can have a direct impact on the product rather than working on one tiny piece of a large organisation.

Jobrooms is a British health and wellness search company that enables people to type or speak what they need in any language and connect directly with verified health and wellness professionals, support figures, service providers and sellers through live audio or video calls. Rather than returning web links or AI-generated answers, the platform uses real-time human interaction to help users access information, guidance, support, services and products. For example, when someone searches “My teeth hurt” — they are connected instantly to a verified Dentist who can assess their situation, provide guidance, answer questions, and, where appropriate, arrange an in-person appointment or treatment afterward. This makes searching for anything related to your health and wellbeing instant and effortless. For health and wellness service providers and sellers, Jobrooms creates a new way to engage with people at the exact moment they are seeking what you provide. Providers earn competitive per-minute rates for live consultations and support, while also benefiting from providing services or selling products during or after calls. Jobrooms was conceptualised and founded in 2018 by entrepreneur Shadrach Sekakande Ugata (Shad Ugata). The business established its initial UK corporate entity as Jobrooms (UK) Ltd on 16 November 2021. In 2023, technologist Ashit Debdas joined as co-founder and Chief Technology Officer, overseeing the company's technical development and digital architecture. The business was subsequently incorporated as Jobrooms Systems Ltd on 4 October 2023.
