The UK’s 885,000 construction micro-businesses deliver £49bn of small construction projects each year. Most run on WhatsApp, spreadsheets, and memory. The unstructured approach costs roughly 20% of each job in scope drift, rework, untracked changes, and delayed compliance.
The industry is also highly wasteful, with 13% of materials never being used, and construction accounting for 61% of the UK’s landfill. We are reliant on this highly fragmented industry to refurbish our buildings to meet performance needs and the targets of the Climate Change Act. However, at current rates, it will take 100+ years to decarbonise the UK’s built environment.
We are building an AI-native workforce of installers to provide high-quality retrofits of buildings. The software will be used to ease administrative burden, reduce project costs, and accelerate business growth. By de-risking installations for both the contractor and the customer, we will enable cost effective delivery across millions of buildings.
As CTO and Co-Founder, you will be the technical half of a two-person founding team. You are a peer to the CEO, a partner, sharing leadership and responsibility. You own the technical vision, the architecture, the hire-and-build plan for the engineering team, and the technical narrative we take to investors and partners.
This is not a “manage the engineers” role. At Pre-Seed, you are writing the production code, making the call on what we build, what we buy, and what we defer.
You will inherit working scaffolding (Ionic Angular mobile app, FastAPI services, agent gateway with LLM SDKs, Supabase data layer, a live React lead-gen site on Cloudflare) and a product roadmap shaped by over 100 installer interviews. You will own the technical strategy that turns that scaffolding into a defensible, AI-native operating system for the trades.
