Sky Valley

Sky Valley Ambient Computing is a London-based pre-seed startup co-founded in 2024 by Iris ten Teije and Noam Tenne. The company is building infrastructure for adaptive software — applications that continue evolving in production rather than freezing into static artifacts at deployment. It positions the current generation of AI-built software as analogous to the first iPhone apps: useful, but constrained by an underlying lifecycle still designed around two-week sprints, manual deploys and one-way pipelines.

The firm's first product, Differ, is an adaptive runtime platform. Drop an existing application into Differ and an agent reads the codebase, infers user intent from observed behaviour, makes targeted edits in a working copy, proxies the dev server and reapplies updates automatically — without ever touching the original repository. Developers continue shipping updates as normal, and changes propagate across each user's diverged copy. Sky Valley calls this an "adaptive exoskeleton".

The company is hiring founding engineers in London and is in the early stages of pre-seed fundraising, with founders publicly recruiting in late 2025 and early 2026. It sits at the intersection of AI infrastructure, developer tooling and applied agents.
