What Is Venture Capital?
Venture capital funds invest in high-growth startups in exchange for equity. Learn how VC works, what VCs look for, and whether VC is right for your business.
Key Takeaways
- VC funds raise money from LPs (pension funds, endowments) and deploy it into startups
- VCs need outsized returns — a 10x+ return from a minority of investments funds the whole portfolio
- VC is only right for businesses with the potential to be very large, very fast
- Most VC funds have a 10-year life — they need exits within that window
How VC funds work
A venture capital fund raises money from institutional investors called Limited Partners (LPs) — pension funds, university endowments, family offices, and fund-of-funds. The VC firm manages this capital as General Partners (GPs), deploying it into a portfolio of early-stage companies over a 3-5 year investment period. The fund then works to grow the value of those companies over the subsequent 5-7 years before exiting — through trade sales, IPOs, or secondary sales. The typical fund life is 10 years.
The power law and portfolio construction
VC returns follow a power law — a small number of investments generate the vast majority of returns. A fund of 20 investments might expect 10 to fail, 7 to return the investment, 2 to return 3-5x, and 1 to return 50x. That single outlier funds the entire portfolio. This means VCs are not looking for businesses likely to return 3x — they need every investment to have the potential to return the entire fund. A VC investing £500,000 into a company from a £50 million fund needs that company to have a plausible path to a £500+ million valuation.
What VCs look for
The consistent filter applied by most VCs is: large market (billion-pound opportunity minimum), strong team (domain expertise, execution track record, complementary skills), defensible product or technology, early evidence of product-market fit (traction), and a plausible path to a very large outcome. Team is weighted heavily at early stages because the product will change but the people executing it largely will not. At later stages, revenue growth rate, unit economics, and competitive moat become more important.
Is VC right for your business?
VC is designed for a specific type of business: one that needs capital to grow faster than revenue can fund, serves a very large market, and has the potential to scale to hundreds of millions in revenue within 7-10 years. Most businesses do not fit this profile. A profitable, growing services business, a lifestyle brand, or a niche manufacturer may be excellent businesses but are not VC businesses. Taking VC funding for a business not suited to the model creates a misalignment — you will be expected to grow 3x per year when steady 30% growth would be a great outcome.
The UK VC landscape
The UK has a deep and sophisticated VC ecosystem, particularly in London. At pre-seed and seed stage, prominent investors include Seedcamp, Entrepreneur First, Playfair Capital, Backed VC, and LocalGlobe. At Series A and beyond, investors include Balderton Capital, Index Ventures, Accel, and Highland Europe. Government-backed funds including the British Patient Capital and British Business Bank programs invest directly and through fund-of-funds, increasing capital availability at earlier stages.
