Customer Success Manager (Growth Strategist)

London (Hybrid) | 4-Day Working Week | High-Growth B2B Tech & Marketing Scale-Up

We’re partnering with a profitable, high-growth scale-up on a mission to redefine global demand generation. Trusted by enterprise brands worldwide, they combine AI-driven tools with expert in-house teams to deliver transparent, ROI-driven results.

We hire to raise the bar.

If you’re a B2B marketer turned customer strategist who thrives on driving measurable growth for clients, this is an environment where excellence is the standard.

The Role

As a Customer Success Manager (Growth Strategist), you’ll sit within the Client Services pod, leading strategic conversations with senior marketers post-sale. You’ll act as the client-side marketing expert—reviewing campaign performance, surfacing ROI-led insights, and shaping renewals and upsells. You’ll be the bridge between delivery and outcomes, ensuring every campaign drives retention, expansion, and long-term growth.

What You’ll Do

• Lead mid-flight and end-of-campaign reviews with marketing contacts (CMOs, Demand Gen Leads, agency partners)
• Analyse campaign performance, ROI, and attribution data to recommend optimisations
• Translate data into ROI stories and industry benchmark comparisons that justify expansion
• Partner with Sales on upsell/renewal proposals, shaping cross-sell opportunities post-sale
• Ensure tracking, attribution, and CRM integrations are set up correctly from day one
• Help clients interpret dashboards and connect performance to business outcomes
• Act as the conduit for product feedback, sharing client insights with Sales Ops and Product teams

What We’re Looking For

• Strong background in B2B marketing or demand generation (SaaS, tech, or agency)
• Marketing fluency: attribution, ROAS, buyer group mapping, nurture flows, and tech stack knowledge
• Experience influencing senior marketing stakeholders as a peer, not just a delivery partner
• Commercial mindset with proven ability to drive upsell/renewal growth through performance data
• Skilled in HubSpot, Salesforce, Marketo, or similar CRM and attribution tools
• Exceptional communicator, resilient, and outcome-focused

Why Join

• Be part of a profitable, high-growth scale-up disrupting B2B demand generation
• Play a pivotal role driving measurable growth for enterprise clients across EMEA & NAM
• Enjoy a unique 4-day working week, hybrid flexibility, and a competitive package
• Work at the intersection of marketing strategy, client success, and commercial growth
