Customer Success Manager

As a Customer Success Manager at Thrive, you play a pivotal role in delivering long-term value to our customers.

You are a strategic partner, commercial thinker, and product expert who builds strong relationships and drives account growth — leading onboarding and training, spotting opportunities for expansion, and working proactively to protect customer health and secure renewals.

You'll manage a portfolio of low- to medium-profile customers, ensuring they receive consistent support, stay engaged, and get real value from their partnership with Thrive, while occasionally taking ownership of higher-profile accounts as needed.

Beyond your customer-facing work, you'll contribute to internal processes, support junior team members, and help ensure the customer perspective is represented across the business.

This role will suit somebody with a desire to drive positive change in social sustainability, ready to play a key role in the continued growth of the company as part of a small but agile team.

The successful candidate will play a pivotal role in helping our customers report their positive impact on society.

Our Values

Key Responsibilities

• Client Management
• Serve as the primary point of contact and trusted advisor for a portfolio of accounts, building strong relationships across multiple levels of the customer organisation, from day-to-day users through to executive sponsors.
• Develop a deep understanding of each customer's business goals, organisational structure, and key stakeholders to inform account strategy and prioritisation.
• Plan and lead regular business reviews (QBRs/EBRs) with customers, presenting platform usage, value delivered, and forward-looking recommendations.
• Proactively engage stakeholders throughout the customer lifecycle, ensuring consistent, high-quality communication and reliable follow-through on commitments.
• Act as the escalation point for complex, high-priority, or sensitive customer queries that fall outside the Support team's day-to-day Help Desk handling.
• Partner closely with the Support team to ensure smooth handoffs and a consistent customer experience, stepping in where relationship context, commercial sensitivity, or account history is needed to resolve an issue.
• Monitor patterns in escalations across your accounts to identify systemic issues and feed insights back to Support and Product.
• Take full ownership of onboarding processes for new accounts, ensuring smooth transitions from Sales and successful early adoption.
• Deliver high-impact platform training sessions tailored to user roles (e. g., Admins, Executives, Suppliers).
• Optimise time-to-value through thoughtful planning and stakeholder engagement.
• Account Growth & Commercial Impact
• Regularly identify opportunities for upselling and cross-selling by understanding customer challenges, expansion plans, and solution gaps.

• Play a key role in increasing Thrive’s Net Revenue Retention (NRR).
• Closely monitor customer health signals including usage, sentiment, and engagement trends.
• Recognise early signs of dissatisfaction or disengagement — particularly ahead of renewals — and take proactive steps to mitigate risk.
• Collaborate with the Head of Customer Success to shape renewal strategies, including executive engagement and success planning.
• Voice of the Customer
• Act as an internal advocate for your customers by gathering, analysing, and sharing feedback with Product, Tech, and Commercial teams.
• Help shape product roadmap priorities based on strategic customer needs.
• Identify themes across accounts and propose process or feature improvements that increase satisfaction and adoption.
• Internal Leadership & Contribution
• Contribute to evolving Customer Success processes, playbooks, and knowledge sharing, if and when requested.
• Represent Thrive’s values in all internal and external interactions.

Essential knowledge & experience

• Proven experience in a Customer Success, Account Management, or client-facing role within a Saa S or software environment, managing a portfolio of accounts.
• Strong relationship-building and stakeholder management skills, with the confidence to engage users through to senior and executive stakeholders.
• Commercial acumen, with a track record of identifying growth opportunities and contributing to retention and revenue targets such as NRR.
• Excellent communication and presentation skills, including experience delivering training or leading structured account reviews such as QBRs.
• A proactive, organised approach to managing multiple accounts and priorities, with strong problem-solving skills.
• Experience using a CRM or customer success platform, such as Hub Spot, to manage relationships and track engagement.
