Clean Growth Fund leads £2.5m investment round in tepeo to support commercialisation of its domestic heating technology.

"We have carried out successful trials of the ZEB in a range of house types, and with the welcome investment from the Clean Growth Fund, we are in a strong position to launch our commercial ZEB in the autumn and extend our product range. We are initially targeting all types of dwellings of up to three bedrooms, but we intend to market future models to larger homes too."
— Johan du Plessis, Founder and CEO

The round was led by Energy Impact Partners with participation from Future Energy Ventures, Cyan Finance, and angel investors.

"Electric vehicles are at an inflection point in most developed markets. The rise of electric vehicles is a significant opportunity for energy utilities, through new and innovative services, that support their customers to go electric. We are very proud to back the team around Nick and Chris as they have already proven that they can scale internationally by appealing to drivers, utilities and car manufactures at the same time."
— Matthias Dill, Managing Partner for Europe
Seed

Maven Capital Partners led the seed follow-on round to support product development and sales growth.

"Guru represents an exciting opportunity for our VCTs to invest in a trusted supplier of carbon saving IoT technology. As a major contributor to greenhouse gas emissions, residential heating presents one of the greatest challenges in global and UK efforts to achieve net-zero emission. Heat networks have a major role to play but, like standalone domestic boilers, they can be hampered by inefficiency. This makes Guru’s sophisticated monitoring and AI-driven analytics technology very attractive to developers and operators as they strive to build efficient and cost-effective heating systems. We look forward to supporting the Guru team and helping them fulfil their growth aspirations."
— David Milroy, Partner
Seed
£1.7M

A syndicate of 15 angel investors led by Andrew Diplock and the Development Bank of Wales backed the round.

"We are now working at full-scale and this represents the final stage of our testing programme before we are in a position to deliver commercial devices to our customers. The business is already creating significant traction in the market and we have a number of revenue generating pre-commercial projects in the pipeline that will further prove the effectiveness of our technology ahead of delivering our devices into first utility scale commercial arrays both here in the UK and overseas."
— Gareth Stockman, Co-founder

£2.1M

Haatch Ventures and NorthInvest led the seed round to support international expansion and product development.

"We’re thrilled to be backing such an ambitious team committed to making the switch to electric vehicles much easier and a more sustainable future for all. Diode is uniquely placed to fill a growing gap in the market and has the potential to disrupt the industry across the UK and the rest of the world."
— Simon Penson, Partner
