We have previously outlined the basics behind the Seed Enterprise Investment Scheme (SEIS), and how established small businesses can benefit from it. Now, we want to showcase the top SEIS funds currently available in the UK, mainly aimed at early-age startups. The following VC (venture capital) firms invest across sectors in early-stage businesses and are offering to help many companies needing additional finances.

What is a SEIS fund?

You may wonder what a SEIS fund is. SEIS funds are a form of venture capital fund that is used to invest in SEIS-eligible companies. Venture capitalist companies are some of the most common equity investors for high-growth startups. VCs buy shares and help private companies to grow and develop. Many VCs were founders of their startups, so they can offer advice and long-term support when investing. Therefore, VC funds invest in riskier portfolios than other funds.

VC funds manage the money of investors seeking private equity stakes in startups and small-to-medium-sized businesses with strong growth potential. However, VC funds are often out of reach to most ordinary investors and are regarded as high-risk opportunities.

Where are VC (venture capital) firms based?

Although SEIS funding can be found anywhere, most private equity and leading VC firms are based in London, with investors offering support to the top startup companies founded in the capital. In 2021, around 51 per cent of equity deals for high-growth UK businesses, backed by some of the best VC firms, were awarded to companies in London.
