Description
Mention Me pride ourselves in providing end-end acquisition solutions to our customers through our leading AI-powered referral marketing solution and our AI-first micro influencer solution. Backed by Octopus Ventures and Eight Roads, we’ve raised $32 million in funding since 2018. Since 2013, our award-winning acquisition platform has driven over 9 million new customers, generating $3 billion in incremental revenue for our clients. There’s a good chance you’ve already come across us while online shopping from ASOS, PUMA, Gymshark, Charlotte Tilbury, or any other of the 500+ global brands we work with. Becoming a Mentioneer means you’ll be joining a driven team, with big plans, at a genuinely exciting time for our business. Role Overview We’re looking for a Customer Success Manager who will be the primary point of contact for a portfolio of 30 or more SMB and mid-market customers, helping them get genuine, measurable value from our MarTech platform. You will build strong working relationships, drive adoption, spot the early signs of risk, and identify opportunities for accounts to grow. This is an ideal role for someone with 1–2 years of experience in a customer-facing SaaS role who is ready to take full ownership of a large, varied portfolio. You are organised, proactive, and energised by the variety that comes with managing customers at different stages of their journey. You do not wait to be asked — you take the initiative, bring fresh ideas, and genuinely care about the outcomes your customers achieve. You will work closely with Sales, Support, and Product teams to ensure every customer in your portfolio has what they need to succeed and to make sure their voice is heard inside the business. Key Responsibilities Customer Relationships Own the day-to-day relationship for a portfolio of 30+ SMB and mid-market accounts, acting as their primary contact and trusted point of guidance. Build strong, positive relationships with key stakeholders at each account, typically marketing managers, CRM leads, and digital teams. Proactively check in with customers at regular intervals, not just when issues arise, to maintain engagement and understanding of their evolving needs. Handle escalations with professionalism and urgency, coordinating internally to resolve issues quickly and keep customers confident. Onboarding & Adoption Monitor product usage across your portfolio and identify customers who are underutilising the platform, creating targeted plans to improve adoption. Run training sessions, walkthroughs, and check-in calls tailored to each customer’s use case and technical maturity. Maintain clear success plans for each account that align platform capabilities to the customer’s business goals. Retention & Growth Own renewal outcomes for your portfolio, forecasting accurately and identifying at-risk accounts early enough to intervene effectively. Proactively identify upsell and cross-sell opportunities and pass qualified leads to the Sales team with relevant context. Reduce churn by building scalable, repeatable processes for engagement, health monitoring, and risk response across a large book of business. Contribute to Net Revenue Retention (NRR) targets by keeping customers healthy, engaged, and growing. Voice of the Customer Gather and consolidate customer feedback from across your portfolio and share structured insights with Product, Marketing, and Leadership. Contribute to CSAT and NPS programmes, following up on responses and owning action plans at the account level. Identify customers with strong outcomes who could contribute to case studies, testimonials, or referral programmes, and connect them with the Marketing team. Process & Improvement Maintain accurate, up-to-date records of customer activity, health scores, and account status in the CRM. Continuously look for ways to improve how the team operates, building playbooks, improvi
