No challenge is bigger than our collective ability to solve it

Maze X is a startup accelerator programme designed to put ambitious impact start-ups on the road to becoming impact unicorns. It is focused on hard-working founders who have the grit to test new ideas and aim for innovative outcomes. The programme is based in Lisbon - Portugal - it is 3-months long followed by 6-months of ongoing support and includes an equity-free cash stipend to help you through your stay.

Our mission

Our mission is to put ambitious entrepreneurs who are tackling the world’s hardest social and environmental challenges on the road to achieve the impact unicorn status: a private company valued at $1 billion that also delivers the equivalent impact on people’s lives or the environment.

It’ll take (much) more than 3 months for an impact venture to become an impact unicorn, but if we start to accelerate the impact of these businesses now, we might just stand a chance of accelerating the rate at which we address some of the world’s most pressing issues.
