Founding Growth Marketer

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

The best marketers right now aren't doing more — they're operating at a different level. They're using AI to compress timelines, run more experiments, and produce work that would have taken a team of five just two years ago. That's the kind of marketer we're looking for.

We're hiring a Founding Growth Marketer who thinks and operates like a full-stack marketer: someone with the breadth to move across content, product marketing, and growth — and the AI fluency to do it faster and smarter than anyone who came before. You won't be a generalist who does a bit of everything. You'll be someone who knows marketing deeply and uses modern tooling to punch well above your weight.

You'll work directly with the founding team to build Seapoint's marketing function from a strong foundation — an existing content strategy with early community traction, a product with clear PMF, and a GTM motion that's starting to scale.

What you'll actually do

• Build a content engine, not just content — take our existing strategy and systematise it: use AI tooling to research, draft, repurpose, and distribute at a pace and quality that feels impossible to do manually. LinkedIn, newsletters, founder communities — owned and operated like a media function
• Own product marketing — work with Sean and the product team to nail positioning and messaging, then build the launch playbooks that get new features in front of the right people with the right narrative
• Partner with the team to build things founders love — work with our engineering and sales teams to create tools, calculators, or resources that deliver standalone value to founders and drive inbound. Think less "lead magnet," more "thing people actually share"
• Run high-velocity experiments — design tests across channels, spin them up quickly using AI and automation, kill what doesn't work, and double down on what does. You're not running one campaign per quarter — you're always running something to accelerate our learning and growth
• Enable GTM with sharp collateral — sales decks, one-pagers, battle cards, partner materials. Produced fast, kept current, and written to actually convert

Establish the marketing foundation — brand voice, channel strategy, metrics that matter. Built to scale, not just to tick boxes

What we're looking for

• You have deep marketing knowledge in content and/or product marketing and insatiable curiosity to learn about the rest of the craft
• You're genuinely AI-native, not just AI-aware. You use tools like Claude, Cursor, and whatever's shipping this week to move faster and think more clearly; but you have high standards for the output. No slop.
• You've shipped things that worked in 0→1 environments — you know the difference between building for scale and building for now
• You're a strong writer with a clear point of view. You can write a positioning doc and a LinkedIn post and they both sound like a real person
• You're an experimentation native — you design tests with intent, read the results honestly, and iterate without ego
• You're excited by the idea of building tools and resources alongside engineers, not just publishing content

Bonus if you're familiar with the likes of MKT1, Lenny's Newsletter, or how modern marketing leaders like Intercom's team think about the discipline — we're building a marketing function in that mould.
