The Greenhouse accelerator supports emerging startups looking to tackle climate change through innovative, scalable, and impactful business ideas.

Our startups have gone on to raise somewhere in excess of $1bn, creating businesses that are now selling products and services that are making a real impact on climate change. Professor Richard Templer Co-founder of The Greenhouse

From up-cycling captured carbon dioxide and harnessing wave energy, to augmenting urban forestry investment and tackling the waste crisis by supporting kids to repair their electronics: The Greenhouse’s fifteen new startups are on a mission to tackle climate change and set up successful businesses along the way.

Undaunted’s twelve-month Greenhouse accelerator programme supports early-stage (pre-seed) businesses to develop the skills and experience needed to succeed in a competitive marketplace. As well as expert coaching, masterclasses, and equity-free grant funding, our Greenhouse startups benefit from being based in central London, with access to free workspace at the Royal Institution.

“We’ve been running the accelerator continuously for ten years, and it’s uniquely focussed on climate change, says Professor Richard Templer, Co-Founder of The Greenhouse. “In that time 70% of our start-ups have gone on to raise somewhere in excess of $1bn, creating businesses that are now selling products and services that are making a real impact on climate change. We are the most experienced and successful accelerator in our field.”

Undaunted in the face of climate change

“Collaboration, creativity and diversity of thought are key to addressing the climate crisis, and so it’s wonderful to see this reflected in the new cohort of ventures.” Michaela Wright Head of Corporate Sustainability, HSBC UK

As Undaunted and its activities evolve, diversifying the climate innovation space becomes a key tenet of its approach. “We know that teams from diverse backgrounds and with diverse experience are drivers of the best innovation”, says Professor Templer, “so I’m delighted that Cohort 4 is our most diverse yet. A majority of our start-ups have female founders, and the spread of ethnic backgrounds strongly reflects the diversity of London.”

“Their start-ups are based on deep technological inventions”, he continues, “things like aerodynamic retrofit for shipping and carbon nanomaterials from captured CO₂. Loads of promise, that I look forward to seeing grow and thrive.”

Co-Founder and Head of The Greenhouse, Naveed Chaudhry, is as excited as ever. “I’ve now supported over 100 climate-focused startups in my role, and never cease to be amazed by the ingenious ideas, inspiring individual stories, and passionate teams that join us on each cohort. As Richard outlined, we are delighted that this cohort is our most diverse yet, and the ideas we will be supporting have the potential to be very impactful.”

“Our role at The Greenhouse, and Undaunted more broadly”, he continues, “will be to support them to help maximise their potential, and create a supportive environment to support their growth.”

The Greenhouse accelerator programme is supported in-part by HSBC UK through the bank’s global Climate Solutions Partnership. 

“Collaboration, creativity and diversity of thought are key to addressing the climate crisis, and so it’s wonderful to see this reflected in the new cohort of ventures.” says Michaela  Wright, Head of Corporate Sustainability at HSBC UK. “We’re excited to continue supporting young companies as they look to develop innovative new products and services that will help the world adapt to and reverse climate change.”
