Customer Success Manager

At Fyxer, we’re not building a traditional Customer Success team - we’re building a high-leverage, commercial motion that turns relationships into revenue and support into strategic partnership. Our CSMs don’t just react - they lead. From $1M to $30M ARR in the last 12 months, making us the fastest growing startup ever in the UK. We are backed by top-tier investors including: Marc Benioff (Founder of Salesforce), Harry Stebbings (Founder of 20VC), David Singleton (Former CTO of Stripe), Madrona (First Investors in Amazon/Snowflake)

This role is focused on the long tail of customers. They’re big enough that onboarding and rollout need structure, champions, and a bit of change management - but the way we support them has to scale. So it’s a mix of 1:1 moments where it matters, and 1:many programs that move cohorts forward.

You’ll work closely with Sales, Support and Product, and you’ll use what already exists - playbooks, templates, digital resources - improving those over time rather than starting from scratch. You’ll also partner tightly with the Digital team to make scaled success actually work.

• Own onboarding end-to-end for this segment, making sure customers activate fast and get value early

• Run structured launch sessions with admins and champions, tied to clear objectives

• Spot expansion signals early

• Own a large portfolio of SMB accounts and be accountable for their health, renewal readiness, and growth

• Stay ahead of renewals by mapping value milestones to timelines and calling risks early

• Run clean save plans when needed, and make sure customers feel supported

• Grow accounts through value: usage patterns, outcomes achieved, and the next logical steps

• Default to using our existing playbooks, assets, and self-serve content, then make them better as you learn what lands

• Work with Digital to build and run 1:many programs that move cohorts efficiently

• Test, measure, and iterate on programs and playbooks based on clear success metrics

• Feed the loop: share customer feedback with Product and help evolve the CS tooling/workflows that make this segment scale
  

• 3+ years in Customer Success or Account Management, ideally SaaS

• Real experience in project management and you Get Stuff Done

• A commercial brain: you’re comfortable linking outcomes to revenue and talking about growth when it makes sense

• A scaled-CS mindset: you don’t jump to bespoke unless it’s truly worth it

• Data-driven and tooling-comfortable

• Startup-ready - fast, flexible, and energized by change

Our culture is intentional. It stems from the fact we're in the race of our lives to reshape one of the largest AI opportunities that exist; email. There is only first or last.

We're going to win by:

• An obsession around the fact that every second counts, we have to move fast with intensity and drive hard every day.

• It's on you. You have autonomy to own your outcomes.

• Never let it slide, be relentless in challenging yourself and others to strive for the best outcome.

This culture is intense; it requires focus and discipline. So we’ll do everything we can to remove distraction, support your wellbeing, and reward your impact.
