Open Energy Market

What Open Energy Market does

Open Energy Market, operating commercially as True Group, is a UK-incorporated private limited company headquartered in Guildford that delivers energy procurement and sustainability strategy services to mid-market and enterprise businesses across the UK and Europe. The company was founded in 2015 (per legal records) and is led by CEO and co-founder Chris Maclean, with a stated mission to help customers save 2 million tonnes of CO2e and £2 billion in energy costs by 2030.

The firm's core technology is the True Platform, a cloud-based system that integrates real-time energy procurement data with carbon emissions data into a single analytical view, enabling customers to compare supplier performance, validate renewable technology investments, and forecast the financial and carbon impact of net zero initiatives. The platform is complemented by a suite of managed services including Energy Procurement, Risk Management, Power Purchase Agreement (PPA) facilitation, the True Performance Fund (a renewable energy investment vehicle), Sustainability Strategy and Implementation, Renewable Technologies advisory, and ESOS compliance services. The company serves multiple verticals, including Manufacturing, Food Production, Data Centres, Hospitality, Castings and Metals, Rubbers and Plastics, and Education, with named reference customers such as Millerknoll, Trelleborg, Oakland International, CGG, and Naylor.

Commercially, Open Energy Market operates a sales-led, consultative go-to-market motion with direct enterprise engagement, using a 'book intro call' conversion mechanism and personalized expert support as primary sales levers. Revenue is generated through subscription-style procurement services and managed-service engagements, with pricing not publicly disclosed and likely tailored per customer. The company was funded in 2018 by Calculus Capital (approximately $4.16 million) and earlier participated in the MassChallenge accelerator. There is no disclosed AI/ML capability, no public listing, no parent company, and no subsequent funding rounds in the available source data.
