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. This is a hands‑on role for a commercially‑minded operator who thrives in ambiguity and is excited to build from zero. You'll work with our largest and most complex customers - and the ones with the most potential - to drive renewals, find expansion opportunities, and turn usage into value and value into growth.
What’s on offer:
- Salary: £80,000 - £100,000 year + bonus + equity + benefits
- This role is onsite in our London office (4 days/week) - fully remote work is not available
What Success Looks Like in This Role:
You’ll be at the frontline of our Customer Success motion - helping define it while actively delivering results. We don’t yet have all the tooling, playbooks, or workflows in place. You’ll help build them. And you’ll do that while making sure our biggest customers are supported, engaged, and growing. Success means:
- Renewals are a no‑brainer because value is clear and relationships are deep
- Expansions happen regularly because opportunities are spotted and acted on
- Customers lean on us as strategic partners - not just vendors.
Your Three Core Responsibilities:
- Drive Retention and Expansion Across Strategic Accounts
- Own a portfolio of high‑potential, high‑complexity enterprise accounts
- Drive the full renewal cycle
- Multithread across stakeholders to ensure broad, embedded relationships
- Surface commercial opportunities through value‑based conversations
- Build the Foundations of Customer Success at Fyxer
- Develop scalable, repeatable playbooks for success, renewal, and expansion
- Help shape our tooling and GTM tech stack - helping choose, implement, and evolve the right systems to support success at scale
- Define and refine KPIs and dashboards that help us track what matters most for our customers
- Be a Strategic Partner to Product, Sales, and Leadership
- Translate customer insights into product feedback and roadmap influence
- Collaborate closely with Sales on account planning and pre‑to‑post handoffs
- Bring a commercial lens to everything - always thinking about how success drives revenue
What Our Ideal Candidate Looks Like:
- 8+ years in Customer Success or Account Management, with a clear track record of owning revenue (renewals + expansion)
- Enterprise experience - you’ve navigated complex orgs, long sales cycles, and strategic conversations
- Commercially driven - you’re not afraid to talk numbers, push for value, and ask for the upsell
- Builder mindset - you’re energized by ambiguity and excited to help define a motion from scratch
- Excellent communicator - confident leading executive conversations, translating technical concepts, and managing internal stakeholders.
- Tooling savvy - you know your way around modern GTM tools and can help us choose and implement what works best
- Startup‑ready - fast, flexible, and energized by change
