Alexandria is a reading platform built around a simple observation: people read more than ever and remember less than ever. The average person forgets most of what they read within a week. Not because of a memory problem. Because the tools were designed for consumption, not understanding. Alexandria brings articles, podcasts, YouTube videos, books, and PDFs into a single library. It reads content aloud with synchronised word-by-word highlighting so you stay focused. Then it goes further. The platform automatically extracts key concepts from everything you consume, connects related ideas across different sources, and uses spaced repetition to bring knowledge back before you forget it. The project started as FlowRead, a Chrome extension that combined text-to-speech with real-time word highlighting. The founder, Elliott Tong, built it after struggling to read technical documentation post-workout and realising no tool on the market would read with him rather than just at him. The extension worked, but it revealed a deeper problem. Knowledge is scattered across dozens of apps and none of it connects. Read-it-later tools optimise for clearing backlogs. Note-taking apps become graveyards. AI chat tools give answers that vanish into conversation threads you never revisit. Alexandria is named after the ancient library because the mission is the same: one place where understanding can live, be accessed, and be built upon. It is designed for students, professionals, ADHD readers, and anyone who consumes knowledge across multiple formats and wants it to actually compound over time.

At ClearWatt, we’re building the platform that helps people buy, sell and own electric vehicles with confidence. One of the biggest barriers to EV adoption is uncertainty. Buyers don’t know the true condition of a battery. Dealers struggle to communicate vehicle performance. Fleets and leasing companies lack the insights needed to make informed decisions. We’re solving these problems using real-world vehicle data, advanced analytics and AI. Our platform transforms complex EV data into simple, trusted insights. Today, our technology helps consumers understand battery health and real-world range, supports dealerships in selling used EVs with greater confidence, and enables fleets, leasing companies and automotive partners to make smarter decisions. We’re already working with some of the UK’s leading automotive, fleet, insurance and energy organisations, and we’re growing quickly as demand for trusted EV data continues to accelerate. Our mission is simple: remove uncertainty from electric vehicle ownership and help accelerate the transition to cleaner transport. We’re a small, ambitious team that moves quickly and takes ownership. As an early member of the company, you’ll have the opportunity to make a meaningful impact on the product, our customers and the future direction of the business. We value curiosity, initiative, pragmatism and a willingness to get stuck in wherever needed. If you’re excited about technology, sustainability and building products that solve real-world problems, we’d love to hear from you.
