London-based energy optimisation firm Tewke has successfully closed a $2 million funding round to advance its AI-driven smart home technology. The investment, which includes participation from prominent venture capital firms and Revolut co-founder Vlad Yatsenko, will fuel the expansion of its flagship product, Tap. This capital injection is set to enhance Tewke's market strategy and further develop its intelligent systems for residential energy management.
Redefining Smart Home Integration
At the core of Tewke's innovation is Tap, a smart light switch praised by T3 Magazine as potentially “the Apple of smart home control.” Designed and engineered in the UK, the device is retrofittable in over 90% of British homes as it requires no rewiring and functions without a neutral wire. This approach provides an elegant and accessible alternative to the complex and costly installer-only systems that currently dominate the market.
However, Tap's capabilities extend far beyond simple lighting control, functioning as a dynamic energy guide for households. It helps users align their electricity consumption with time-of-day tariffs, effectively reducing both energy bills and carbon footprints. This device represents the first step in Tewke’s broader vision to achieve optimal home energy efficiency through contextual, AI-powered intelligence and automation.
Strategic Investment and Industry Acclaim
The new funding round features a notable roster of investors, including consumer venture capital firm JamJar Investments, impact fund Cur8 Capital, and specialist VCs Energy Mix Ventures and Project Ventures. The backing from such respected entities provides a powerful validation of the company's mission and technology. CEO Piers Daniell stated this support affirms the strength of the team and the product they have built.
This financial milestone follows a period of significant recognition for the company, which has achieved B Corp certification and joined the Made in Britain collective. Tewke also received a prestigious Red Dot Award for Design Concept, underscoring its commitment to innovation and sustainability. These accolades reflect a holistic dedication to excellence, from hardware design and local manufacturing to responsible supply chain practices.
Pioneering AI for Energy Efficiency
Looking ahead, Tewke is advancing its artificial intelligence capabilities with TewkeAI, a contextual framework announced alongside Google at Slush 2025. This system leverages data from Tap’s nine integrated sensors, which monitor movement, air quality, and temperature patterns within the home. The insights gathered enable the system to understand household behaviours and optimise energy use accordingly, creating a more responsive living environment.
The latest capital will be instrumental in expanding the engineering team to develop sophisticated neuro-symbolic AI systems. Co-founder Rowan Dixon highlighted the technical challenges of building next-generation electronics and AI in the UK. He emphasized that the funding will allow Tewke to scale its proven technology and double down on its commitment to engineering excellence for greater residential energy performance.
Future Outlook and Market Expansion
With all core technology developed in-house, from patented hardware to its custom Tewke OS, the company is well-positioned for growth. Following a successful debut at CES 2025, Tap received positive feedback from energy-conscious consumers, professional installers, and major distribution partners. This market validation confirms a strong demand for Tewke's user-centric approach to smart home energy management.
As Tewke prepares to scale its operations in the UK and internationally, it has already initiated a subsequent funding round to accelerate its trajectory. The company's growth is further bolstered by non-equity funding from Innovate UK, cementing its role as a key innovator. This strategic expansion aims to deepen its AI and energy optimisation capabilities for a global audience.
In conclusion, Tewke's successful $2 million funding round marks a pivotal moment for the company as it scales its innovative smart home solutions. By combining accessible hardware with powerful AI, Tewke is not just creating smarter homes but is also empowering consumers to actively manage their energy consumption. The company is poised to become a significant force in shaping a more sustainable and intelligent future for residential living.
