Venture Capital: What It Is, How It Works and What VCs Look For

What Is Venture Capital?

Venture capital (VC) is a form of private equity financing where investors — known as venture capitalists — provide funding to startups and early-stage companies in exchange for equity (an ownership stake). VCs typically invest in companies with high growth potential that cannot access conventional funding such as bank loans.

Unlike loans, VC funding does not need to be repaid. Instead, investors take a share of the business and expect to generate returns when the company is acquired or goes public through an IPO.

How the VC Funding Process Works

Venture capital deals follow a structured process. A startup pitches to VC firms, the firm conducts due diligence, and if they proceed, they negotiate terms via a term sheet before completing legal documentation and closing the round.

Sourcing: VCs source deals through networks, accelerators, warm introductions, and inbound pitches. Cold outreach rarely succeeds — founders need warm connections to top-tier firms.

Due diligence: VCs assess the team, market size, product, traction, competitive landscape, and financials. Early-stage deals focus heavily on the team; later-stage deals emphasise metrics and unit economics.

Term sheet: A non-binding document outlining the key terms of the investment — valuation, ownership percentage, board rights, and investor protections.

Closing: Legal documents are signed and funds are transferred.

Funding Rounds Explained

Pre-seed: The earliest funding, often from founders, friends and family, or angel investors. Amounts typically range from £25k to £500k.

Seed: First institutional round. Used to validate product-market fit. Typical range: £500k to £3m.

Series A: Scaling a proven model. Requires strong metrics and a clear path to profitability. Typical range: £3m to £15m.

Series B and beyond: Later rounds for companies scaling aggressively. Amounts grow significantly at each stage.

Valuation and Equity

Pre-money valuation: The company's value before the new investment is added.

Post-money valuation: Pre-money valuation + investment amount. The investor's ownership is: Investment ÷ Post-money × 100.

Example: A £2m investment at a £10m pre-money valuation gives a £12m post-money valuation and 16.7% ownership.

Dilution

Every time a company raises a new funding round, existing shareholders get diluted — their percentage ownership decreases as new shares are issued. Anti-dilution provisions protect investors if the company raises at a lower valuation in a future round (a "down round").

What VCs Look For

Team: A strong, experienced founding team is often the single most important factor at early stages.

Market size: VCs need large addressable markets (typically £1bn+) to generate returns given their portfolio model.

Traction: Evidence of product-market fit — growing users, revenue, or engagement metrics.

Defensibility: A competitive moat — proprietary technology, network effects, or switching costs.

Unit economics: At later stages, LTV/CAC ratios, gross margins, and payback periods become critical.

Key Terms to Know

Liquidation preference: Investors receive their money back before founders in a sale. A 1x liquidation preference means they get their investment back first.

Pro-rata rights: The right to invest in future rounds to maintain ownership percentage.

Vesting: Founder shares typically vest over 4 years with a 1-year cliff to align long-term commitment.
