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.
About the Role
We’re hiring a Founding Customer Success Lead to build customer success at Elyos from zero. You’ll work directly with Adrian (CEO) and partner closely with product and engineering to ensure customers achieve measurable value quickly and consistently. This is a builder role. You won’t inherit a playbook – you’ll create it. You’ll own onboarding, success metrics, renewals, expansions, and the feedback loop that shapes the product as we scale.
Key Responsibilities
- Customer Outcomes & Retention
- Define what “success” means for different customer segments and track it rigorously
- Monitor customer health signals and intervene early to prevent churn
- Run regular check‑ins, reviews, and performance discussions with customers
- Identify expansion opportunities through increased usage, new channels, or additional workflows
- Own renewals and retention outcomes as the company scales
- Fix small bugs in the product to satisfy customer needs
- Be the voice of the customer internally, ensuring real‑world usage shapes the roadmap
- Translate customer feedback into clear product requirements and priorities
- Partner with product and engineering to close gaps surfaced during onboarding and usage
- Help define standards for conversation quality, workflows, and automation logic
- Create customer success processes, playbooks, and tooling from scratch
- Define metrics, reporting, and success dashboards
- Build and eventually lead a customer success team as we grow
- Establish a high bar for ownership, responsiveness, and customer impact
Experience
Experience in customer success, implementation, or related fields is required.
