Foundry 5

Foundry 5 is an AI-first development studio and advisory based in London. Since 2021, we've helped founders and enterprise teams turn ideas into products that actually work scoped honestly, built collaboratively, and designed to scale. We build across three areas: AI, web, and mobile. Our services span AI development, full-stack web builds, mobile apps (Flutter and React Native), MVP development, UX/UI design, and custom software and most projects combine more than one. Speed matters when you're chasing market fit, so we take products from a blank page to a live MVP in about four weeks. Not a throwaway prototype — a real product with real infrastructure that can handle what comes after launch. Everything ships with clean, well-documented code your next developer can actually maintain, and security is built in from day one rather than bolted on afterward. To date we've shipped 50+ products for 50+ clients across FinTech, FemTech, fashion, and more including Gather, Ove, and Loom with a 100% on-time delivery record and government-trusted work. We're founder-led, so the people making the technical decisions are the same people on your calls. No handoff nightmares. No buzzword soup. No silence. Just clear timelines, weekly progress updates, and products built to hold up
