About us

Fospha is dedicated to building the world's most powerful measurement solution for online retail. For over a decade, we've helped teams make smarter decisions with full‑funnel marketing insights, forecasting, and optimisation. With Fospha, every team moves faster and grows smarter. Trusted by leading brands across three continents, including Huel, Oh Polly, and Dyson, Fospha manages $4 billion in annual ad spend. We're scaling fast across London, Mumbai, and Austin – and we're now looking for a Marketing Activation Associate to join our Marketing team.

You'll be responsible for building, running, and improving the activation layer that turns our marketing strategy into qualified pipeline — across ABM, outbound, inbound, events, and partner‑led motions.

The Role

As a Marketing Activation Associate you’ll own Fospha's outbound and ABM pipeline systems — designing, running, and iterating on the workflows that turn signals into conversations. You’ll work hands‑on with tools like Claude, HubSpot, and our GenAI hub, and you’ll be accountable for moving accounts through the funnel from MEL all the way to SQL. You’ll take full ownership of existing workflows from day one and build new ones as the role matures — including leading initial sales calls and representing Fospha at industry events. This is an ambitious, high‑ownership role with a clear commission upside tied directly to the pipeline you create.

Critically, you’ll be joining a company that’s serious about GenAI. Fospha runs an active GenAI Hub where teams build MCP servers, experiment with Claude Code, and create internal tools that genuinely change how work gets done. We don’t just talk about AI — we expect you to dive in, build things, and find new ways to make our GTM machine faster and smarter. This role is based in our London office and is designed for someone who is early in their career but exceptionally driven — someone who wants to understand the full GTM stack and grow into a senior commercial, operations, or growth role.

Key Responsibilities

• Own and architect GTM workflows - Design, build, document, and iterate on signal‑based outbound systems using Apollo, HubSpot, Dripify, and AI tooling. You treat every workflow as a system to be optimised.
• Translate intent signals into qualified pipeline - Monitor market signals — job changes, engagement data, events, inbound activity — and route accounts through enrichment workflows to activate them from MEL → MAL → MQL → SQL.
• Build with GenAI - Actively create prompts, automations, and AI‑assisted sequences that sharpen personalisation, compress cycle time, and improve conversion. You’re a builder, not a button‑presser.
• Own pipeline metrics end‑to‑end - Track and report on response rates, acceptance rates, meetings booked, and pipeline influenced.
• Connect Marketing to Sales with precision - Ensure the right accounts are enriched, correctly routed, and handed to.
