  • £5m in venture capital raised to date
  • 4.8 star rating in the App Store, from c.100 reviews


We founded Clim8 so anyone can invest in companies that are making a positive impact on climate change. We believe that there is a lot of “greenwashing” happening. In contrast, we have an in-house investment team that focuses on renewable energy, clean technology, sustainable food, electric mobility, clean water, & the circular economy.

An estimated $2.4 trillion needs to be invested, every year, into clean energy, to meet the UN targets on climate change to avoid “catastrophic damage”. The market opportunity in the UK alone is vast, with some £1.6 trillion held in retail investments.

We launched the Clim8 Invest app on IOS & Android in private beta in October 2020 and then in the App Store in March 2021. Our users have invested from £25 all the way up to £97k. We charge a fee as a % of assets under management.

We have already raised £5M+ of venture capital plus a recent £2M in airtime from Channel 4 Ventures. Our investors include a venture capital fund backed by the British Business Bank & Atomico, the Future Fund, plus 3,000 investors from two successful Crowdcube campaigns (overfunded by 300% & 500%).

Crowdcube investors now have the opportunity to invest alongside Channel 4 and join the Clim8 journey. We are raising further funding to accelerate user acquisition & launch new product offerings including pensions.


The team has many years of experience in sustainability, technology and financial services.
