Founding Customer Success Lead

We're building the next generation of customer service with AI Agents. Our agents answer calls, reply to emails and WhatsApp messages, make bookings, take payments, and operate the CRM in the same way a human would.

We founded Elyos in June 2023 and took part in the Y Combinator S23 batch. Our founders spent four months in San Francisco living and breathing AI. Since then, we've been growing revenue 30% month on month and shipping fast. It's been wild so far - and we're just getting started. We recently raised a $13m series A to turbocharge our growth.

If you care deeply about customer outcomes, love building functions from scratch, and want to sit at the centre of product, engineering, and customers, this role is for you. As our Founding Customer Success Lead, you'll define how customers onboard, adopt, and expand with Elyos, and you'll own retention and long term value from day one.

You'll work hands on with AI agents that handle real customer conversations, bookings, and payments, helping customers trust automation in mission critical workflows.
