Solving the world's issues, one app at a time.

At 3 Sided Cube, we build digital platforms with global organisations, charities and movements, to make change happen.

What you’ll be doing

  • Proactively driving and delivering new projects with our existing clients
  • Owning the sales process from inception to completion, working independently where necessary but also supporting project and delivery teams
  • Developing strong and sustainable relationships with clients
  • Delivering strategic client account plans whilst showcasing a thorough understanding of clients’ markets
