Role
Who you are
- We’re looking for someone who was an Account Manager in a past life - someone who understands how to sell through success, multithread across an org, and turn commercial goals into long-term partnerships
- 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
What the job involves
- At Fyxer AI, 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
- This role is onsite in our London office - Remote work is not available
- 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
- 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 AI
- 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
- 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
Application process
- Violaine Yziquel, our CCO, is the hiring manager
- Submit your CV (no need for a cover letter)
- We’ll review it
- An initial call with someone from the hiring team to review your experience and motivation for joining (30 mins)
- Customer case study with a panel (45 minutes)
- Meet more of the team (30 minutes)

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.
