Role
Who you are
- We're looking for someone who thinks like a GM - commercially obsessed, operationally excellent, and ready to roll up their sleeves while building the function that becomes the backbone of our revenue growth
- 8+ years in Customer Success or Account Management, with 3+ years leading teams in high-growth B2B SaaS
- Proven track record building CS from early stages and owning revenue targets (NRR, expansion ARR)
- Commercially driven - you've driven expansion revenue and are comfortable in C-level conversations
- Operationally excellent - you've built playbooks and made data-driven decisions
- Exceptional leader and communicator who can influence cross-functionally
- Startup-ready - you thrive in ambiguity, move fast, and are hands-on when needed
What the job involves
- Hiring Manager: Violaine Yziquel, CCO
- At Fyxer, we're not building a traditional Customer Success team - we're building a commercial engine that turns customers into strategic partners and retention into predictable expansion revenue
- This is the leadership role for someone who's done it before - someone who's built and scaled Customer Success Management from the ground up, turned it into a revenue driver, and knows how to balance strategic vision with hands-on execution
- You'll own the entire post-sales motion: renewals, expansion, customer health, and the systems and playbooks that make it repeatable
- You'll lead a small but mighty team of CSMs, work alongside Sales and Product leadership, and be a key voice in how we scale from 32M to 100M ARR and beyond
- You'll be responsible for building and leading the Customer Success Management function at Fyxer - not just managing a team, but defining the motion, the metrics, and the muscle memory that makes customer growth inevitable
- Success means:
- Strong net revenue retention because expansion is systematic, not opportunistic
- Renewals are predictable and frictionless because we've delivered value
- Your team is a revenue engine - CSMs are hitting expansion targets and commercial outcomes are clear
- Customer insights drive product roadmap and GTM strategy
- Build the Team: Take full responsibility for building and leading a commercially elite Customer Success function. From hiring and coaching to performance management, you create a team of CSMs who own retention and drive expansion. You set a high bar, define clear expectations, and ensure the team delivers measurable revenue outcomes
- Own the Number: Net Revenue Retention and expansion ARR sit squarely with you. You bring rigor to forecasting, renewals, and account growth. You step into key deals when needed, balancing strategic oversight with hands-on execution to consistently hit and exceed commercial targets
- Design the Engine: Architect the scalable operating system behind Customer Success. From onboarding and adoption to renewal and upsell, you build playbooks, dashboards, and processes that create visibility, reduce risk, and unlock growth. Everything you implement works today - and scales to 10x tomorrow
- Be the Voice of the Customer: Act as the strategic bridge between customers and the business. You translate customer insight into product direction and GTM strategy. You partner closely with Sales, Product, and Leadership to ensure we’re building what matters - and turning customer success into a true competitive advantage
Our take
Built with the intention of turning the burden of email drafting into a business's competitive edge, Fyxer AI delivers AI executive assistants that can organise inboxes, draft emails in the tone of voice of each user, and write "better-than-human" meeting notes. Plugging directly into Gmail, Outlook, Slack, Teams, Google Meet and Zoom, its service is simple to use without the need to grasp additional software.
Fyxer is especially useful for industries that spend large amounts of time composing emails. Think real estate, consultants and recruiters, all saving time through the pure-play AI software of Fyxer and its open-source AI models and retrieval augmented generation. The company claims that its customers send 53% of the email drafts generated on its platform.
As more and more professionals turn to AI to save them time in their everyday tasks, Fyxer AI's secure and streamlined service is sure to gain more attention. Things certainly look to be going well, as in 2024, the company raised $500K in just three weeks from existing customers and their networks. It also rocketed from $1m ARR to $22m in just 10 months in 2025 - a sure-fire sign of the value users see in its offering

Company values
- What do we value? We're very intentional about adding new people. We believe a small team of exceptional people working hard at a problem they care about will always outperform a larger, more unfocused team. That means you'll need to bring an intensity to this role that might not be expected at other companies but it also means you'll be fast-tracked into roles with greater responsibilities far earlier.
