Funding sources for cleantech companies


Are you looking for funding sources for cleantech companies?


There are many funding sources for cleantech companies now available to help you on your journey.  This could be pre-seed, seed, Series A or B funding,


The article below gives information about the funding climate in general and a list of sources.


Microsoft and Amazon encourage confidence in the sector


When large corporates like Amazon and Microsoft announced available funds to make the planet greener it was seen as encouraging news for the cleantech sector.  This is the view of Shayle Kann, Managing Director of Energy Impact Partners and Abe Yokell, managing partner and co-founder of Congruent Ventures.  They discussed how the sector is faring since the pandemic in a recent Interchange podcast.




Deals bounce back since July 2020


Things looked bleak for entrepreneurs looking for funding for cleantech companies in the Spring of this year. According to figures from Crunchbase, venture capital deals were down 44 percent from March to June compared with last year. Seed-stage deals were affected the most, down nearly 60 percent. But Series B deals were also impacted. The funding environment was challenging for startups at any stage of funding. 


However deals are now finally coming back. Crowdfunding platforms like Seedrs which allow people to become investors in smaller, innovative companies with positive environmental aims may have helped things.  Investors on these platforms regularly cite social, economic and environmental reasons to invest.  Companies that have achieved an exit have used a range of funds including crowdfunding to obtain funding.




Smart investment firms are putting the planet at the heart of their strategies


According to The Daily Telegraph, smart investment firms are putting the planet at the heart of their strategies. At least 22 per cent of the UK asset management industry is now sustainably invested, according to a 2019 government report.


Despite its current economic woes, the UK has become more attractive to renewable energy investors according to EY’s latest Renewable Energy Country Attractiveness Index.  Greg Jackson, CEO at unicorn startup Octopus Energy, has said that “The energy market is worth $2 trillion, excluding petrol, diesel and oil. As we decarbonise transport, that’ll become a $4 trillion market. This is the biggest thing since the internet – and it might be bigger than that.”


Having previously warned that companies will “go bankrupt” if they don’t work towards net zero, Mark Carney, former Governor of the Bank of England. has stated that the transition to carbon neutrality represents “the greatest commercial opportunity of our time.”


There is also growing interest in ESGs which rose after Larry Fink, CEO of the world’s largest asset management company BlackRock announced that “sustainability- and climate-integrated portfolios can provide better risk-adjusted returns to investors.”


A range of funding sources for cleantech companies is available.  These include large corporate funds to NGOs as well as investor panel pitching opportunities and accelerator programmes.  The latter often result in the organisers making funding available to a select number of participants.  There is also a list of funds, including government help in response to the coronavirus on the Oxfordshire Greentech website.
