Software Development London 51–200 employees Founded 2013 Privately Held

what3words replaces traditional coordinates and street addresses with 3-word identifiers for any 3m × 3m location on Earth. The stack spans React, Node.js, Rust, Kubernetes, and AWS — a modern polyglot setup suited to high-throughput geolocation services. Active hiring is sales-led (3 open roles vs. 2 engineering), with velocity accelerating; concurrent projects focus on ecommerce integrations, logistics partnerships, and mobile reliability, suggesting a push to scale platform adoption rather than product depth.
