About Hook

We’re building the future of customer growth. At Hook, we use AI and Machine Learning to help businesses predict revenue with accuracy, drive customer loyalty, and capture massive value from their existing customers.

We’re a Series A company who ranked 33 out of 100 on the Sifted fastest growing startups and we have raised $multi-million in funding from some of the top investors in Europe and the US (e.g. Balderton Capital and Lightspeed) and have an enviable list of customers that we’re working with including some of the fastest growing companies in the world. We’re looking for ambitious people that want to be part of our meaningful vision of changing how businesses engage with their customers, and of building one of the world’s leading workplaces for great people along the way.

The Role:

We are looking for an experienced Customer Success Manager/Account Manager to partner with our ever-growing customer base. What makes this role unique is that many of our customers are customer success professionals themselves, so you’ll be working with people who deeply understand the challenges and opportunities in CS. That means you’ll need to bring credibility, insight, and technical depth to every conversation.

In this role, you’ll own the customer lifecycle end-to-end: from initial strategy sessions to adoption, value realisation, and renewals. You’ll be responsible for ensuring our customers achieve measurable success with Hook, while also shaping how we define and deliver customer success as a discipline.

Hook’s Customer Growth function is not about reactive support, it’s about being a strategic, data-driven partner. We believe the future of Customer Growth lies in blending commercial ownership, technical expertise, and consultative problem solving. This is a chance to be part of that future and to help define how it looks.

If you love solving customer problems, excel at juggling multiple projects, and have a knack for turning complex data and product features into clear business outcomes, we’d love to speak to you.
