Rowan Dixon is Co-Founder and COO at Tewke, a London-based climate tech company revolutionizing home energy management through AI-enabled smart devices. He leads the technical team across hardware, electronics, and software engineering.

Rowan studied Design Engineering at Imperial College London, graduating in 2020, and worked at Microsoft before co-founding Tewke during COVID with serial entrepreneur Piers Daniell. He was the lead product engineer when the company launched in 2020.

Rowan designed and built Tewke's first prototypes and developed Tewke OS, the company's proprietary operating system. He has overseen the creation of Tap, which won the prestigious Red Dot Award for Design Concept and was called the smartest light switch ever made by T3 Magazine.

Tewke has raised 2.75 million pounds in equity funding, including backing from Revolut co-founder Vlad Yatsenko, and participated in Google for Startups Accelerator: AI For Energy in 2025. The company manufactures all electronics in the UK and has set up global supply chains.

Tewke's Tap smart switch reduces home energy bills by 30% without requiring rewiring, making it compatible with over 90% of UK housing stock. The company is expanding internationally and launched TewkeAI voice assistant powered by Google Gemini in 2025.
