Founding CSM

About Seapoint

Seapoint is building the financial home for European startups and scale-ups. We’re an AI-powered business account that handles everything from payroll and expenses to invoice payments and reporting — all in one place.

Founded by Sean Mullaney (former European CIO at Stripe) and a team of alumni from Stripe, Wise, Wayflyer, Nubank and Tide, we’ve just raised $3 million in pre-seed funding led by Frontline Ventures. After nine months of building, we’re now in private beta with dozens of VC-backed startups who are finally getting the bird’s-eye view of their finances they’ve always needed.

The problem we’re solving is real: European startups are stuck between neobanks (too small) and traditional corporate banking (too big). They’re juggling 4–6 different financial products, running processes manually, and earning no interest on cash deposits. We’re changing that with AI automation that handles the tedious financial work — so founders can focus on building their businesses instead of managing spreadsheets.

About the role

We’re hiring our Founding Customer Success Manager to build the customer success function from the ground up at Seapoint.

You’ll work directly with founders and finance teams from Europe’s most ambitious startups  helping them onboard, succeed, and scale with Seapoint.

This is not a traditional CSM role. You’ll be both strategic and hands-on: designing processes, defining metrics, shaping our customer experience, and ensuring every startup we work with becomes a passionate advocate for Seapoint.

In your first 12 months, you will:

• Build and own our customer success foundation across onboarding, engagement, and retention processes from scratch
• Work directly with founders and finance leads to help them get the most value from Seapoint
• Design and deliver smooth onboarding experiences, ensuring customers get to first value quickly and confidently
• Capture customer feedback and translate insights into product improvements by working closely with Product and Engineering
• Define key success metrics (activation, adoption, NPS, expansion) and set up early systems to track them
• Build scalable support and enablement materials (guides, videos, help centre content, playbooks)

Act as the voice of the customer to ensure every decision across product and GTM reflects our users’ needs

What we’re looking for

• You’ve worked in 0→1 environments before, building or scaling customer success processes from scratch with limited resources and a small team.
• You have a strong passion for helping founders and finance teams succeed, and you understand their pain points and motivations deeply.
• You’re customer-obsessed, proactive, empathetic, and able to turn complex problems into simple solutions.
• You bring experience in B2B, SaaS, or fintech, ideally supporting startups or high-growth companies.
• You’re analytical and data-driven, comfortable defining success metrics and using insights to improve customer outcomes.
• You’re independent and resourceful, able to build playbooks, processes, and tools from scratch.
• You’re an excellent communicator: clear, thoughtful, and confident across email, video, and live conversations.

What we offer

• Competitive salary with meaningful equity in a fast-growing fintech startup
• Work directly with experienced founders and operators from Stripe, Tide, Wise, Nubank, Wayflyer and other fintech unicorns
• Front-row seat to building category-defining financial infrastructure for Europe's startup ecosystem
• Flexible hybrid working from our London base
• Budget for events, networking, and community building activities
• Learning and development opportunities in fintech and AI
