BigChange
👤 Martin Port (Built and sold Masternaut, an early UK vehicle-tracking SaaS (2009), then wired that telematics edge into BigChange job software.)🌐 sitemartinport.com
A fleet-telematics founder rebuilt his trick as trade software: track the van, schedule the job, send the invoice.
Will it work? · our read
Sticky by design. Field-service firms rarely replace the tool that runs every van and invoice. Port fused telematics into job scheduling, passed $38M recurring, and sold to Simpro in 2024.

BigChange: £30M+ recurring revenue, 140% 3-yr growth (Dec 2023)Great Hill Partners invests £75M at £100M valuation (2021)Martin Port — founder of Masternaut and BigChangeBigChange reports record-breaking start to 2023
Revenue is STATED, not filed: BigChange's own Dec 14, 2023 blog says 'recurring revenues at BigChange now stand at more than £30m a year,' with 140% three-year growth and a £100m+ contracted order book across 2,400+ organisations (bigchange.com, page opened and matched). Converted at about 1.27 that is roughly $38M; this is recurring/ARR-style revenue, first-party and unaudited, so verified true but not FILED. Great Hill Partners invested £75M (about $95M) in 2021 at a £100M valuation (UKTN); Simpro Group acquired BigChange on Oct 25, 2024, with founder Martin Port staying a shareholder (Wikipedia). Masternaut facts—an early UK web vehicle-tracking SaaS, majority sold to Hub Telecom in 2009—are from Wikipedia. Rival bar weights are our read of rough reach/mindshare, not revenue. We never score you.
