Client Success Manager (UK)

About StructureFlow

StructureFlow is a structural intelligence platform; a new category of technology that transforms how legal, professional services firms and alternative finance funds master complexity. Our clients work with structures that span multiple entities, jurisdictions, and counterparties: transaction structures, group arrangements, fund configurations, reorganization plans. Those structures hold the intelligence that drives decisions, governs capital flows, and determines outcomes. Yet most of that intelligence is trapped. Static diagrams that are out of date before the ink is dry. Spreadsheets that capture data but not relationships. Documents scattered across matters and inboxes, with no single source of truth. The result: decisions made without complete visibility, risks that aren’t seen until too late, and structural complexity that becomes a brake rather than an asset. StructureFlow changes that. We give professionals a living, connected model of the structures they work with — something they can Map, Model, and Move. Understand how everything fits together. Test how it responds to change before a decision is locked in. Communicate it with clarity and conviction to clients, investors, and regulators. Our clients don’t just see their structures, they master them. We’re not a diagramming tool. We’re not a spreadsheet. We’re structural intelligence: visualise data, unlock insights, act - in one interface.

We are hiring for a Client Success Manager to join our team. The CSM role at StructureFlow exists to deliver what our product promises: mastery over complexity. That means taking customers from their first interaction with the platform through to the point where StructureFlow is genuinely embedded in how they work; not a tool used occasionally, but the way they Map, Model, and Move on deals and matters. You’ll manage a portfolio of enterprise accounts across our UK & European customer base – primarily law firms, PE funds, and accountancy/tax practices – from pre-sales pilots through to onboarding, expansion and renewal. You’ll co‑own the client relationship across its full lifecycle, together with the Account Executive assigned to each client. This isn’t a reactive role. We don’t wait for clients to tell us something isn’t working. We track adoption signals, maintain live health scores, and intervene early, which means you need to be comfortable reading data, drawing conclusions from it, and acting without being asked to. You’ll also be involved pre‑sale: for complex pilots and structured evaluations, you’ll work alongside the Revenue team, contributing the CS perspective on onboarding risk and helping shape what success looks like before the contract is signed.

Our CS function has implemented a clear and structured operational framework, a set of handbook‑documented standards, and the tooling to support them, but there’s also real scope to contribute to how things evolve. If you want to inherit a fully codified playbook and execute it, this probably isn’t the right environment. If you want to operate within a structured framework while also helping to improve it, it is.

What you’ll be doing:

• Pre‑sales pilots – For complex evaluations, work alongside the Revenue team from Selection onwards, contributing the CS perspective on deal quality and continuity before the contract is signed.
• Onboarding & first value – Own accounts from contract signature, finalise the Customer Success Plan (CSP), and drive each account to a named first‑value milestone on a live piece of work.
• Adoption – Move accounts from "this works for a few people" to "this is how we do things" — through proactive health monitoring, QBRs grounded in impact, and cohort expansion.
• Expansion & Renewal – Manage renewals from six months out, maintain a live whitespace plan, and develop expansion opportunities to the point of handoff to the AE.

Requirements

Domain experience is a must. Our clients are experts in their respective fields. They’ll know immediately whether you understand their world. The background that fits best is someone who has received training from or worked within professional services – accountancy/tax, law, restructuring, M&A advisory or alternative finance – and then moved into a client‑facing SaaS or technology role. You should be able to discuss deal structures and transaction flows without needing them explained to you.

Essential Skills And Experience

• 3+ years in enterprise CS/account management in B2B SaaS/professional services tech.
• A passion for creating and iterating on strategy and executing against a plan.
• Track record managing renewals and expansion.
• Comfortable managing senior stakeholders, not just operational contacts.
• Experience with typical CS tooling: HubSpot, Planhat, Gainsight, ChurnZero, or equivalent.
• You write well: a significant amount of the role is written communication.
• London based and willing to work from our London office at least 2-3 days per week.

Desirable Skills And Experience

• Legal, Accounting or Finance qualifications or prior experience working in these industries.
• Understanding of the broader culture of compliance governing how firms adopt digital tools.
• Ideas for how AI technology can be used to accelerate the CS workflow and drive client experience.
• Experience contributing to a CS function being built, not just inheriting a mature one.

What Success Looks Like

By month 3… You’ve built real relationships with your clients — they see you as part of their team and they trust your judgment. Each client has a documented first‑value milestone. You understand their world well enough to have a credible view on where StructureFlow fits into it, and your health scores reflect the strength of those relationships, not just product adoption metrics.

By month 6… Your clients feel secure and well managed. QBRs, check‑ins, and escalation paths all run through a rhythm that clients find reassuring rather than administrative — they know what’s coming, and nothing falls through the cracks. At least one of your clients is willing to advocate for us, and you’ve used this to support other pre‑sales pilots, showing prospects what that experience looks like from the inside.

By month 12… Your renewals are going through smoothly, because the relationship and the value were never in doubt. Expansion conversations succeed because you are seeing genuine client need and working through the value case collaboratively.
