Europe's leading climate innovation start-up accelerator

The Greenhouse is one of Undaunted's flagship activities: we support the development and growth of early-stage, technology-focused businesses looking to tackle climate change.

Our key focus: tackling the climate crisis

When startups join Undaunted, they become part of a thriving environment and community focused on supporting startups to accelerate the development of their ideas and realise impact. Embedded within Imperial’s Grantham Institute – Climate Change and the Environment, we have all the elements needed to support successful climate innovation: first and foremost, passion for the planet in our DNA.

The Greenhouse is fully independent and wholly motivated to work for the public good.  We take the planet’s point of view at every stage of the entrepreneurship journey and do not take equity in the businesses that we support.

We are pioneers in nurturing climate innovators with a proven success record

We build a bridge from the experimentation and discovery stage of technology development to commercial success, nurturing innovation until it is ready to be scaled and deployed. Our activities stimulate the commercial sector to follow and develop a wider ecosystem where green solutions can flourish.

Over the past 12 years we have developed and refined a successful model for accelerating applicable, practical and adaptable solutions that have global impact:

  • We've supported over 175 startups on our 12-month, part-time programme, always with the climate at its core.
  • Startups benefit from up to £20k in equity-free grant funding – we don’t take equity from our founders.
  • Our alumni have gone on to raise over £1bn of funding create over 2,000 jobs globally. Meet some of our alumni community.

Teams on The Greenhouse are encouraged to iterate rapidly, experimenting, testing and refining their propositions, whilst working with leading experts and practitioners across climate science, engineering and fundamental science, entrepreneurship and business.

Teams also have access to the world-class facilities and technical resources available at Imperial. This focus and setting is unique to Undaunted and in parallel strengthens both the science behind the proposed climate solutions, and the underlying business proposition, establishing a foundation for commercial success.
