Posted on Nov 17, 2025
We are committed to promoting a diverse and inclusive workplace - a place where we can each be ourselves and do the best work of our lives. At Tracksuit we consider a unique perspective, diverse experience and a growth mindset to be of greater value than ticking every box on an JD. If you think you have what it takes but don’t have the exact experience we’ve set out, please still get in touch and apply. We’d love to chat!
At Tracksuit, we provide beautiful, radically affordable, always-on brand tracking which is easy to use compared to traditional methods. We recognise that sounds like a ton of buzzwords for marketers, so what it really means is that we did over 50,000 surveys last month to find out what real humans think and feel about the world’s best brands and their competitors.

- You get to innovate: You’ll have license to run experiments, imagine surveying from first principles, and implement solutions with a product team to build the world’s best survey engine.
- Your work is directly tied to business outcomes: As you shape the trajectory of Tracksuit, you’ll be able to directly measure your impact and demonstrate your contribution to the business.
- We don’t have a roadmap dictated to us: You’ll have high-level business goals and outcomes, but it’s up to you to define the problems and solutions.
- We’re backed by product-legend Lenny Rachitsky: Founder of Lenny’s Podcast and Lenny’s Newsletter. In Lenny’s words: “Across the thousands of startup decks I've looked at, I've almost never seen a growth trajectory like the growth Tracksuit has see
