Richard Warley, CEO of BigChange, and Martin Port, chairman of BigChange
BigChange, a leading all-in-one mobile workforce and job management solution, was founded by Martin Port in 2013.
Private equity firm Great Hill Partners invested £75m into the company in 2021, valuing BigChange at £100m. Martin Port remains an investor in BigChange, and is also chairman of the company.
BigChange has gone from strength to strength in the past year. New business wins rose 40% in the first nine months of 2022 when compared to the same period the year before, bringing in new orders worth £24.5m. The company aims to get to £60m in annual recurring revenues by 2025.
“Martin Port is one of the great entrepreneurs of his generation and, most importantly, he is also a great human being – and he brings both of these aspects to his work every day. He is brilliant at identifying opportunities, he is endlessly curious about people and about how to make things better and he is relentlessly creative and determined in overcoming obstacles.
“His huge empathy and insight about people makes him highly astute at identifying and nurturing talent and he is equally very generous in offering opportunities to people who may have been struggling and then helping them flourish. He gives a 100% of himself to the business and causes that he supports and I would say that he is fast approaching ‘national treasure’ status.”
Richard Warley, CEO BigChange

Martin Port invested in Storiboard in September 2022, as part of a wider funding round with other investors.
Users share their experiences on Storiboard through videos uploaded to the app, live podcast recordings and groups where people can interact and ask questions.
“Martin Port was my first investor. He listened, asked some probing questions and came in. He believed in what we are doing and in the team. But unlike other angel investors, Martin didn’t just leave it there.
He introduced me to his network, many of whom joined the round and he made regular contact to see how it was going.
Best of all, Martin thinks about the companies he invests in. He is constantly creating new ideas, making introductions to potential talent and developing ideas around new revenue streams. Having Martin Port on your team is gold.”

Electron Green brings scale, expertise and customisable business models to property developers looking to transition to renewable energy ahead of the UK’s targets to reach net zero by 2050.
“Martin is a unique investor, whom we are extremely fortunate to have as a shareholder. Not only does he have wide ranging and relevant experience, but Martin also has a diverse pool of connections whom he is prepared to contact and encourage to support the business.
“He always has our business on his mind and whenever he comes across an opportunity that could help, he takes action. Building a business is hard and can be lonely as the founding entrepreneur.
“Having Martin as a shareholder, with his enormous relevant and personal experience, is like having a guiding angel by your side.”
Daniel Green, Founder and CEO Electron Green
