Reading Time: 12 min

Equity crowdfunding platforms allow investors to invest directly in sustainable or green startups that are addressing one or more of the 17 SDGs (Sustainable Development Goals). Here we investigate the top European equity-based crowdfunding platforms and review the best options.


Equity-based crowdfunding has had a significant growth in the last 10 years. It all started with the lack of funding sources available in the aftermath of the 2008 financial crisis. Once banks restricted and limited their loan offering, startups and SMEs had to find out alternative sources of financing.

Equity crowdfunding is one of the four main business models of crowdfunding available for individual investors, which are:

  • Reward-based crowdfunding: backers provide funding to individuals, projects, or companies in exchange for non-monetary rewards or products. E.g. Kickstarter and Indiegogo
  • Donation-based crowdfunding: donors provide funding to individuals, projects, or companies based on philanthropic or civic motivations with no expectation of monetary or material rewards. E.g. Kiva
  • Debt-based crowdfunding: individuals finance loans for other individuals (P2P), projects, companies, or real estate (P2B). E.g. Lendahand, Trine and GoParity
  • Equity-based crowdfunding: individuals or institutional funders purchase equity issued by a startup or small company. E.g. Seedrs, Crowdcube, Invesdor, Funderbeam

Reward-based and donation-based crowdfunding are considered non-investment-based options since once the user contributes to those projects, no financial return is expected. The funds are allocated to the projects and as an outcome, either backers or donors receive non-monetary rewards. Alternatively the projects create a social or environmental impact.

Debt-based and equity-based crowdfunding are an investment-based crowdfunding options, where investors should expect financial returns. Debt-based crowdfunding, also known as peer-to-peer (P2P) lending or crowdlending, is the most common business model with a global volume of more than $40 billion in 2018 (excl. China). On the other hand, the European equity-based crowdfunding is still a small mrket , reaching $1.16 billion in 2017, and expected to reach $2.3 billion in 2020.

When investing in green startups, individual investors from Europe and the UK have several equity crowdfunding platforms to choose from. In this post, we will look into the main investing options, evaluate their main differences, and discuss how sustainable investors can select and invest in green startups.

How to invest in green startups?

The regulatory changes that took place in the last 10 years enabled small investors to join attractive early-stage investments previously only available to VC (venture capitalists) and accredited investors. Equity crowdfunding platforms allow investors to allocated as little as 10 Euros into a startup and become a shareholder.

When looking specifically at green startups, investors must be even more cautious when assessing if the social and environmental impact claimed by the startup is indeed effective and that it is addressing a relevant social or environmental problem.

As we will see below, the leading equity crowdfunding platforms have a broad selection of startups, covering different industries, from fintech to cleantech, from beauty products to beverages. Sustainable investors need to learn how to navigate those options to find attractive green startups that create real impact.

We list below a guide to select green startups created by SeedTribe, the equity crowdfunding platform from the Angel Investment Network:

  • Business Model
    • Do you have a sound business model?
    • Is there a big enough market?
    • Is it the right time and place for this type of business?
    • Does the valuation seem fair?
    • What are the Key Performance Indicators?
    • How long until you make revenue?

Top 5 European equity-based crowdfunding platforms by amount raised (including the UK)

Seedrs Logo Green Black - equity crowdfunding


Seedrs is one of the largest equity-based crowdfunding platforms in the world. Founded in the UK in 2009, the company has a global presence and has raised a total of £1 billion in 1,235 highly diverse deals. The platform constantly offers new opportunities for investors willing to invest in early-stage startups.

Seedrs was also the first equity crowdfunding platform to implement a Secondary Market, allowing investors to sell their shares and exit their investment before the startups’ secondary transaction (e.g. acquisition or IPO). The Secondary Market is in beta and works in cycles: the market opens on the first Tuesday of every month and closes on the following Tuesday. Buy orders can only be placed when the market is open.

Main features:

  • Secondary Market increases the liquidity of the investment, but also allow investors to buy startup shares after funding campaign.
  • Auto Invest: automated investment tool allowing algorithmic investments based on investor selected criteria.

How to find green startups in Seedrs?

Seedrs does not distinguish green startups from standard startups. Among the several sectors in Seedrs, “Energy” and “Healthcare” are the ones with a higher likelihood of finding sustainable startups. However, investors will need to do the heavy lifting when looking for green startups. Seedrs could easily implement a “green/eco/sustainable” tag that would facilitate investors’ lifes when looking for green startups.

crowdcube - equity crowdfunding


Founded in 2011, Crowdcube is at par in volume of deals with Seedrs, reaching 1 million members and an accumulated £1 billion raised in funding campaigns. Recently both companies, Seedrs and Crwodcube announced a merger, where Crowdcube will own 60% of the shares and Seedrs the remaining 40%.

This merged company will dominate the European equity crowdfunding in market share. In the company’s own words, it will accelerate growth, in the UK and overseas, and become the world’s largest private equity marketplace”. The merger is still to be approved by the Competition & Markets Authority (CMA) and the Financial Conduct Authority (FCA).

Main features

  • Direct Community Offer (DCO): this is Crowdcube’s version of a secondary market, allowing investors to sell their shares at an internal secondary offer, pre-IPO, without releasing more shares. However, liquidity is still limited, since to qualify for the DCO the companies need to decide to launch a DCO and need to fulfill Crowdcube’s strict criteria.
  • Deal structure: Crowdcube uses both a direct ownership model and a nominee structure mode. Direct ownership allows investors to directly invest in startups without intermediaries.

Among the platform several sectors, Crowdcube offers sectors “Energy & Renewables” and “Heathtech & Healthcare”.

The risks of investing in equity-based crowdfunding platforms

Equity crowdfunding is among the riskiest asset types available for individual investors. Early-stage startup ups might have zero revenue at the time of investment and might encounter several challenges during the growth phase. Below we list the main risks of investing in green startups through equity crowdfunding:

Loss of capital: Most startups fail. Investors should be aware that 100% of their original capital is at risk and that they will need to diversify their investments into 5 or 10 startups to increase their chances of positive return.

Dilution: early-stage crowdfunding is usually used by startups to bring in cash flow and promote the business until a later and larger funding round is received. Investors should look for deals with ‘pre-emption rights’, which will give them preference in future shares offerings.

Limited liquidity: Except for Seedrs and Funderbeam, equity crowdfunding platforms do not have an efficient secondary market. Therefore, most investors will have to be prepared to hold their investments for 4 to 7 years, until the company is acquired, or an IPO takes place. Some platforms indicate that investors can sell their shares to other investors, however, this process can be quite complex and time consuming for smaller investors.

Lack of dividends: startups at growth phase rarely distribute dividends. All profit is usually reinvested in the business to accommodate operational growth. Shareholders of early-stage companies should expect no return on capital until the startup exit.

Dependence on the management team: the success of the startups is highly dependent on the performance and experience of its management team to keep the company on track, achieve milestones, and attract future funding. Before investing it is recommended to check the background and experience of the team behind the startup.

How to diversify your equity crowdfunding investments?

It is recommended to diversify your investments across platforms, regions, development stages, and sectors/industries. It is recommended to create a portfolio with at least 10 startups. Be sure to select platforms where the minimum investment is aligned with the amount that you can allocate to a high-risk asset.

Based on the equity crowdfunding platforms available for European investors listed above, investors could select one of the large global platforms and combine it with a local niche platform. For example, invest in 5 startups from Seedrs and 5 startups from Invesdor, Companisto, or Green Rocket.
