Role Overview thirdflow is looking for a Partnerships Manager to drive new business and build strategic partnerships that fuel the next stage of our growth. You will own the commercial relationship lifecycle – from identifying and qualifying prospects through to closing and expanding accounts. This is a founding commercial hire with a direct line to the founders and a clear path to commercial leadership as the agency scales.
We help B2B companies create predictable, compounding demand through content-driven strategies that convert audience trust into business growth. Our media-first approach has helped scale some of Europe’s largest B2B brands – from launching ABM pilots for the world’s largest insurance broker to building communities of 13,000+ attendees across multiple conferences.
We work at the intersection of strategy, content, and distribution, with a focus on what actually converts. The founding team brings deep experience in scaling B2B media and services businesses, and we are building thirdflow to be the agency that ambitious B2B companies turn to when they want marketing that drives pipeline, not vanity metrics.
What’s missing is a dedicated commercial engine to turn that momentum into consistent, scalable revenue. New Business & Pipeline Ownership Develop outbound strategies that open doors with senior marketing and commercial leaders at B2B companies
Identify and develop partnerships with complementary platforms, technology providers, and industry communities Commercial Strategy Feed commercial insights back to the founding team to shape product development and go-to-market strategy 3+ years in B2B sales, business development, or partnerships – ideally within a media, marketing, or professional services environment~ Strong commercial instincts – you can read a room, shape a proposal on the fly, and know when to push and when to listen~ Familiarity with B2B marketing, demand generation, or content-led growth is a strong plus
You’re equally comfortable on a cold outreach as you are presenting to a room of marketing directors. You combine commercial sharpness with genuine curiosity about how B2B companies grow, and you build relationships that outlast any single contract. You want ownership – not a territory carved out for you – and you’re motivated by the chance to shape a commercial function from scratch, not just inherit one.
