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.

K4 Tech Solutions is a remote-first team of under twenty people building fintech products: neobanks, payment platforms, mobile apps and SaaS tools. What we work on: payment systems and banking integrations, PCI DSS-compliant platforms, neobanking apps for iOS and Android, SaaS products, and LLM-based automation. Stack: Node.js, NestJS and Express on the backend; React, Next.js and Angular on the frontend; Swift, Kotlin and Flutter on mobile; Python and OpenAI for AI integration. How we work: weekly demos, clear deadlines, and estimates that come from the engineers who do the work. Async by default — we keep meetings few so nobody's day gets fragmented. A small team means engineers see the whole product and take part in architecture decisions. We look for people who want to understand the problem domain, not just close tickets.

Steperly turns screen recordings into editable step-by-step guides, interactive demos, and narrated walkthrough videos for sales enablement, customer onboarding, support, and training—letting teams record once and repurpose content across guides, demos, and videos without recreating workflows in multiple tools.
