London-based Tewke has announced the closing of a second funding round of £1.5 million. Investors include JamJar Investments, Cur8 Capital, Energy Mix Ventures, Project Ventures, and Vlad Yatsenko (co-founder and CTO of Revolut).

Technology and Goals

Tewke develops smart home technologies to simplify energy management. Its flagship product, Tap, is designed and engineered in the UK and requires no rewiring. It is compatible with most UK homes, working even without a neutral wire.

Tap supports household energy optimization, helping users shift electricity consumption according to time-of-day tariffs, reducing costs and emissions. Tewke develops its core technology in-house, including patented hardware and firmware, as well as its proprietary operating system, Tewke OS.

Contextual Artificial Intelligence

In 2025, Tewke introduced TewkeAI, a contextual AI framework that uses data from Tap's nine onboard sensors to analyze behavior, movement, air quality, and temperature within the home. The funding will support the expansion of the engineering team and the development of neuro-symbolic AI systems to improve residential energy performance. The company's growth is also supported by non-equity funding from Innovate UK.
