MARTIN PORT
Entrepreneur, business adviser, philanthropist and angel investor
Martin Port is an Israel-based serial entrepreneur and angel investor on a mission to support and grow businesses with the potential to hit unicorn status (a $1bn valuation).
In 2024, he started his latest venture, Build Concierge, an AI-powered customer engagement platform. This secure, cloud-based, AI-powered engine allows service businesses to manage and automate calls, chats, WhatsApp, SMS, emails, and bookings in real time. Intelligent and capable, it understands intent, responds instantly, and follows up automatically.
Following an oversubscribed investment round in the summer of 2025, Build Concierge has been valued at £35m. The AI start-up has announced plans to grow to 150 people over the coming years.
Martin has already founded and built three successful companies during the course of his career. His previous venture, the workforce management platform BigChange, was launched in 2013. With Martin at the helm, BigChange became one of the leading employers in Yorkshire and a recipient of the prestigious Queen’s Award for Enterprise – one of the highest official honours for UK companies.
In 2021, BigChange secured a £75 million investment from Boston-based private equity firm Great Hill Partners, valuing the company at £100 million.
Just three years later, BigChange was acquired by global field service management leader Simpro Group in a deal that valued the business at £330 million. Martin Port remains a significant minority shareholder in Simpro.
Outside of his entrepreneurial endeavours, Martin is involved with charities and is keen to invest in and support other fast-growing companies.
In 2022, he led a seven-figure funding round in online tradesperson marketplace Rated People and has invested a six-figure sum into analytics and business intelligence platform Panintelligence. He is also an investor in Handshaik, StoriBoard and Electron Green.
