The story

Founded 2013 as a UK-focused job management and fleet tracking SaaS for field-service SMBs (plumbing, HVAC, drainage, fire & security). Layered embedded payments (BigChange Pay) and a Right Fuel Card partnership on top of the core FSM platform to monetise cash flow and fleet spend. Now positioned as an AI-first FSM operating platform after the 2024 acquisition by Simpro Group and the 2025 Lightning launch.
