Advertising Sales Lead

This is a senior advertising sales role. We’re looking for someone with a proven track record of selling advertising, media or adtech solutions, using existing agency and brand relationships to generate revenue through Forest Ads.

We’re Forest. You know, those shared e‑bikes in London that look like trees. We’re London’s most sustainable shared e‑bike operator. We bridge the gap between affordability and sustainability, using advertising revenue to offer our users up to 30 free minutes per ride. Our mission is to help cities move greener—and we’re growing fast. Alongside our mobility platform, we’ve built Forest Ads, our in‑house advertising business.

Brands can sponsor rides in exchange for advertising space within the Forest app, helping riders access subsidised travel while connecting advertisers with highly engaged audiences across London. We help advertisers reach people at the right place and time through in‑app advertising, first‑party audience insights and location‑based targeting. Working at the intersection of mobility, media and technology, we’ve partnered with brands like Deliveroo, Virgin and Octopus Energy, as well as agency groups such as OMD, Havas and WPP.

Our campaigns consistently outperform industry benchmarks, with some delivering results more than 10x above industry averages.

This is a senior advertising sales role responsible for growing Forest’s digital advertising revenue through agency partnerships, direct brand relationships and high‑value advertising deals. You’ll lead agency and direct brand sales, develop strategic partnerships, mentor and develop a growing team of Business Development Executives and SDRs, and personally close high‑value opportunities. You’ll also work closely with Product and Technology teams, using customer feedback and market insight to evolve Forest’s advertising platform and identify new commercial opportunities.
