We work with exceptional teams on big, important ideas. If you meet these criteria we'd like to hear from you!


  1. Big climate impact
    You should believe you could realistically avoid, reduce or capture half a gigaton CO2e a year at scale.

  2. Early stage
    Your company should be pre-seed to Series A in terms of funding. 

  3. Scientific innovation
    You should be developing a hard science, IP-heavy technology innovation.

  4. Scientific viability
    The concept must be scientifically viable at scale. 

  5. Financial impact
    Brilliant technologies only have a climate impact if they scale. So your business model needs to be financially viable too.

  6. EIS eligible
    This is an EIS fund, so your company, sector and product must meet, and continue to meet, the HMRC guidelines for EIS eligibility, including "permanent operations" in the UK.


Investing in start-ups and early stage businesses involves risks, including illiquidity, lack of dividends, loss of investment and dilution. It should be done only as part of a diversified portfolio. Any investments are targeted exclusively at investors who understand the risks of investing in early stage businesses and can make their own investment decisions. Any pitches for investment are not offers to the public.
