Spruce is a London-based B2B SaaS startup building end-to-end software for heat pump installers, covering the full journey from initial enquiry through to final compliance paperwork. Founded in 2023 by Joseph Saxby, the platform features an estimate tool, heat loss survey designer, CRM, and automated reporting — all aimed at helping installers halve admin time and double sales conversion rates. The company has grown to 500+ UK installer customers in under two years and is positioning itself as the operating system for the home renewables supply chain. Spruce raised a $1.13M Seed round in April 2024, backed by investors including 6 Degrees Capital, Antler, Atomico, and Cur8 Capital, and has since continued scaling its team.
