Role overview
Fintech SaaS1-10 employees
Dolfin builds agentic financial operations infrastructure for SMB platforms. Think Ramp intelligence, but white-label and embedded inside any B2B platform. Instead of another standalone finance tool, Dolfin provides native AI agents that operate autonomously inside the platforms SMBs already use.
What you will do
- Own the messaging and positioning strategy to effectively translate complex financial infrastructure into compelling narratives for PSPs and vertical SaaS platforms.
- Execute a full-stack marketing plan including SEO, paid ads, LinkedIn thought leadership, and case studies to drive demand and brand consistency.
- Coach the founders on practical marketing crafts like GEO and newsletter management, building internal capabilities rather than just delivering outsourced tasks.
Who this is a fit for
- Proven experience in B2B fintech or infrastructure marketing, ideally at an API-first company specializing in payments or embedded finance.
- An 0-1 builder mindset with hands-on technical marketing skills across content, demand gen, and performance channels.
- Strong communication skills with a "coach mindset," comfortable working 1-2 days per week in a hybrid London environment on a contract basis.
Why this role is remarkable
- Shape the marketing function for a company operating at the intersection of embedded finance and agentic AI, two of fintech's most exciting themes.
- Work directly with founders in a "done with you" capacity, enjoying high autonomy and the ability to influence the company's core positioning.
- Join a Balderton-backed startup with existing traction and paying customers across the UK and EU, ensuring your work has immediate market impact.
