About Martin Port


Martin Port, born 29th July 1962, grew up in Leeds, West Yorkshire.


Having left school at 15, he has tried his hand at selling everything from bread and jewellery to business cards and cigarettes. But his greatest success has been in technology.


Martin founded web-based vehicle tracking company Masternaut in 2002, leading it to Europe’s largest vehicle tracking service before selling the business in 2011 as part of a £60m deal.


He then formed BigChange in 2013 to revolutionise mobile workforce management. In 2021, he sold a majority stake to US private equity firm Great Hill Partners that valued the business at £100m. 


Martin is now chairman of BigChange and hopes to take the business to unicorn status with a valuation of $1bn within the next 3-5 years.

In 2022, he led a seven-figure funding round in online tradesperson marketplace Rated People and he invested a six-figure sum into analytics and business intelligence platform Panintelligence. He is also an investor in life experience platform StoriBoard and solar energy specialist Electron Green.
Martin is also involved with many charities and is a key champion and supporter of local businesses, playing an active role in Business in the Community for Yorkshire and the Humber.
Martin aims to support fellow entrepreneurs through mentorship and funding, and writes a weekly blog on LinkedIn.
