Autonomous AI customer service for trades businesses (formerly Elyos Energy)
About Elyos AI
Elyos AI provides autonomous AI-driven customer service agents specifically for the trades and field services industry, including sectors like plumbing, electrical, and HVAC. Founded in 2023 by Adrian Johnston, Philippa Brown, and Panos Stravopodis as part of the Y Combinator accelerator program, the London-based startup aims to solve the operational challenge of missed customer calls, which often results in lost revenue for these businesses.
Read full description
The founders' collective experience underpins the company's focus. Brown was previously Head of Operations at OVO Energy, managing over 1,000 engineers, while Stravopodis, the CTO, has over a decade of experience as a VP of Engineering at companies like Bulb and Zoa. Johnston is a second-time founder with a background in mathematics from Oxford, an MPA from Harvard specializing in AI policy, and experience optimizing call centers with Boston Consulting Group.
The company's core product is an AI agent that functions as a 24/7 front-office staff member, capable of handling unlimited concurrent calls to manage peak demand. These agents can answer inbound calls, book and reschedule jobs, provide quote reminders, qualify leads, and dispatch engineers, integrating directly with industry-standard CRM and job management systems. By automating these administrative tasks, Elyos AI allows businesses to reduce operational overhead, improve customer response times, and capture more jobs. The company reported raising a $3 million seed round in October 2023 and a $13 million (£9.7M) Series A in January 2026, bringing its total funding to $16 million. The new capital is intended to expand engineering teams, deepen CRM integrations, and prepare for international expansion in 2026.
