Building the customer success function rather than inheriting one

I’m working with an early-stage AI startup in central London who are building out their customer success function, and they want someone to lead it.

Their product takes on the operational admin behind property management. A voice agent answers agency phones and handles everything from viewings to maintenance, connecting those conversations to the systems and actions needed to get the work done.

You’ll own the client relationship once customers go live. Three things sit on top of that: converting pilot customers into paying ones, building the automation that lets a small team handle a growing book, and owning onboarding from sales handoff through to go-live. It’s a technical customer success role rather than account management.

What They’re Looking For

B2B SaaS: 3+ years client-facing, in customer success, technical account management or solutions

Building with AI: automations or agents you’ve built yourself, not only used

Pilot to paid: you’ve converted trial or pilot customers into paying ones

APIs, integrations, webhooks and data imports: comfortable in the detail

Diagnostics: telling configuration, data quality, user error and genuine bugs apart

Onboarding: owned end to end, from sales handoff through to go-live

Four days a week on site in central London

What You’ll Work With

The AI assistant and the knowledge base that decides how it answers tenants

Communication channels: WhatsApp, email and SMS

Data imports from property management systems

Linear, Notion, Slack and HubSpot

Nice to Haves

Twilio or the WhatsApp Business API

CS operations tooling you’ve built: health monitoring, escalation workflows, onboarding trackers

SQL: basic querying

UK residential tenancy or property compliance

Building an onboarding process from scratch at a startup

Why Join

You’ll shape the customer success function rather than inherit one, working closely with the founders and the product team, with what you learn from customers going straight into the roadmap.

The AI-first part is real. They want someone who’ll build the health monitoring, escalation triage and reporting themselves, so a small team can handle a growing client base without hiring linearly. If you enjoy working out what should be automated and what stays human, that’s most of the job.

Worth being straight about the environment. The founders are in seven days a week and say plainly it won’t suit anyone who wants a conventional nine to five. Priorities move quickly and you’ll be expected to take ownership from the start.

The Package

Salary from £60,000, depending on experience

Equity

Victoria office, four days a week on site

Wednesdays working from home
