This is an opportunity to join a fast-growing, venture-backed AI startup transforming how property businesses operate. Its AI platform automates the operational work that slows down property managers, lettings teams and build-to-rent operators, allowing customers to run more efficiently while delivering a better service to tenants.

Already live with pilot customers and building towards commercial scale, the business is looking for a commercially minded, technically capable Customer Success professional to help turn early traction into long-term customer growth.

As Lead Customer Success Manager, you will own the client journey from sales handover and onboarding through to adoption, pilot-to-paid conversion, retention and account growth. You will be the key link between customers, Product, Engineering and the AI team, ensuring customer feedback directly shapes the platform as it scales.

This is not a traditional relationship-management role. You will build AI-enabled workflows and practical CS processes that allow a small team to support an expanding client base without simply adding headcount. You will be comfortable in product dashboards, working with customer data and diagnosing whether an issue is configuration, data quality, user error or a genuine product bug.

• Key role in a high-growth AI startup with genuine influence on how the customer function is built.
• Work closely with founders and a small, high-calibre team.
• Competitive salary and meaningful early-stage equity.
• Exposure to a product solving real operational problems in a large, underserved market.
• Four-stage interview process with pace for the right person.

This role would suit someone who is:

• Experienced in a client-facing B2B SaaS role such as Customer Success, Technical Account Management, Solutions Engineering or a similar technical customer role.
• Commercially strong, with clear evidence of driving adoption, pilot-to-paid conversion, retention and expansion.
• Hands-on with AI tools and automations, with examples of designing or deploying workflows that solve operational problems.
• Technically confident around APIs, integrations, data imports and exports, webhooks and product dashboards.
• A structured problem-solver who can identify the root cause of a…
