About us

We are a venture-backed startup in stealth, building data infrastructure for the age of AI agents. A small, senior founding team, already working with design partners and early enterprise customers. We are in stealth now, and that will not last long. We need someone to make sure the world understands what we have built the moment we step out. We will tell you what it is in conversation, under NDA.

The role

You will be our first Head of Marketing. You build the function from scratch and own the story we tell.
This is not a role for a specialist who runs one channel well. It is for someone who has seen the whole board: positioning, product marketing, content, demand generation, events, community, brand. You know how the pieces connect, and you are happy getting your hands dirty in all of them before there is a team to delegate to.

You will define our positioning, narrative and category as we move from stealth to market, and work closely with product and the founders to turn a complex technical platform into clear customer value.





You will own product marketing at the sharpest end: the competitive map, the battle cards, and exactly why we win against every alternative. You will produce content that earns attention from technical buyers and build developer advocacy from zero, so the engineers and platform teams who touch our product become our loudest champions. You will run high-trust, high-touch programmes for enterprise buyers, from executive dinners and peer events to customer storytelling and founder-led thought leadership.

You will market the way 2026 allows: AI-native from day one. Agents and modern tools across research, content, targeting, campaigns and measurement, not as a gimmick but because that is how a small team punches far above its weight. You will design that operating model, choose the stack, pick the agencies and hire the early team.

What you bring

Experience leading marketing for a complex B2B technology product, ideally in data pla
