thirdflow is a fast-growing media-first GTM agency focused on one thing: helping B2B companies create predictable, compounding demand. Founded by operators who have built and scaled multiple ventures in B2B media, thirdflow partners with ambitious companies that want marketing to be their growth engine. We design and run content-led demand generation systems built to drive pipeline and revenue, not vanity metrics. Our work sits across strategy, content, and distribution, with a strong focus on what actually converts.
Alongside our agency work, we build and operate our own B2B media brands, including content platforms and live events in fast-growing niches. These properties give us first-hand insight into what drives attention, trust, and demand, and they shape how we work with clients day to day. Over the coming months we plan to launch further media brands and events across multiple B2B sectors.
Our culture
We are builders and entrepreneurs. That means moving fast, experimenting, and learning by doing. We value strong execution, clear thinking, and people who take ownership of their work. We are still shaping our playbook. You will join a lean team where responsibility comes early and you will be expected to get stuck in from day one. The role will not suit someone looking for a slow ramp-up or a narrow remit. It suits someone who wants to learn quickly by doing real work with real responsibility.
The role
We are hiring a Marketing Associate to support the delivery and execution of marketing programmes for thirdflow and our clients. The role is hands-on and focused on the work itself. You will help execute content and demand generation campaigns, support client delivery, and build strong marketing fundamentals across our agency and our own media brands. You will work closely with the marketing and senior team, with direct exposure to how we think about strategy, delivery, and growth.
What you will do
- Support the execution of content-led demand generation programmes for clients and our own media brands
- Help produce and manage content across formats including articles, reports, social posts, newsletters, podcasts, and video
- Assist with campaign setup and execution across channels including email, organic, paid, and partnerships
- Track performance metrics and help report on results
- Support day-to-day client delivery and communication
- Help document processes and improve how we deliver work
- Support the wider team on ad hoc marketing projects as the business grows
What success looks like in the first 6 months
- You are reliably executing marketing tasks to a high standard
- You understand how our content and demand programmes work end to end
- You can manage your workload independently and hit deadlines consistently
- Clients and the team trust you to deliver what you are responsible for
- You are developing strong fundamentals in B2B marketing and delivery
