About Powster

We are a creative studio based in the London Fields area in Hackney, with a solid team of 24 people. Our team works across two main areas:

  • Showtimes Platform: which powers most of the major movie websites across the world boasting all the major movie studios as our clients.
  • Creative Builds: which can range from projects making interactive music videos to projecting tweets on the houses of parliament.

We like to think that anything is possible when pitching, and if we haven’t done it before we’ll pull together, work it out and make it happen. This comes from having a drive to make the unseen! When bolstered by the very diverse and strong team we can adapt to anything thrown at it, from technical, interactive builds to large scale video productions.

Our platform gets 2.2 million visits a week and has 2 component parts, the all-movie destination ( and the individual movie pages ex:(Star Wars, Ant-Man, The Martian, etc). This is a really exciting time to be joining the team as we are in the midst of launching a lot of new features and capabilities within our product and you will be able to contribute ideas to this product plan and help to build it out! You’ll be working on building out tons of exciting new movie websites, developing the showtimes platform further, and taking it to the next level for major movie studios internationally.
