Kinds of Investors Through the Stages of Venture Capital Funding and Investing:
1. Angel Investors:
This isn’t always a professional network that hosts pitches every week; it’s individuals who undertake a significant degree of risk and invest their own money at the early stages of a start-up, from ideation through to running pilot tests and onboarding their first set of clients. They may also provide new entrepreneurs with valuable mentorship and connections.
Paul Buchheit, the creator of Gmail and an early employee at Google, is known for investing early in Dropbox & Airbnb.
2. Seed Funds / Pre-Seed & Seed Venture Capitalists:
For a startup, this marks a transition from the early stages to the stage of building an infrastructure for growth. There are small VC firms, or micro VCs, that specialize in it and help startups build MVPs, validate markets, and prepare startups for larger funding rounds.
A popular example of this is First Round Capital, which is known for its investments in Uber, Notion, and Square.
3. Early-Stage Venture Capital Firms:
By this stage, a startup typically seeks investment from early-stage venture capital firms, which is often in Series A or Series B rounds. They have a product-market fit and initial traction. The investors help scale further and expand the team.
For instance, Andreessen Horowitz (a16z) at the Series A or B stage in companies like Instagram, Airbnb, and Coinbase.
4. Growth-Stage Venture Capital Firms:
When VCs choose to participate in Series B or C, they are looking to invest in startups that are scaling swiftly. They seek steady revenue growth, expanding customer bases, and a clear path to profitability.
A great example of this would be Tiger Global Management, which is known for investments in rapidly scaling startups such as Stripe, ByteDance, and Databricks.
5. Corporate Venture Capital (CVC):
These startups are no longer dealing with product validation and market fit—investment arms of large corporations fund startups that align with the corporation’s long-term objectives.
GV, formerly referred to as Google Ventures, is the VC of Alphabet Inc. and has funded Slack, Robinhood & Flatiron Health.
6. Private Equity/Late-Stage Investors:
At the late-stage or pre-IPO phase, start-ups have reached mainly their market potential, and their innovations are tested and proven. Private equity firm investors are eager to step in at this point. Investing companies like The Blackstone Group focus on mature startups that are preparing for acquisition or a public listing.
7. Incubators and Accelerators
While incubators & accelerators don’t have the traditional investing approach, these programs offer seed funding, mentorship, and resources in exchange for ownership through a percentage of equity, and play a crucial role in shaping early-stage startups.
Popular examples of this kind are Y Combinator and Techstars.
We have a vague idea of whom to approach as an investor at what stage of a start-up. Let’s examine the seven stages of venture capital. However, before we delve into it, here’s a statement that presents the level of risk and reward when a VC invests in start-ups.
“In venture capital, you don’t have to win every time. You just have to win big when you do.”
— Fred Wilson, Co-founder of Union Square Ventures
Venture Capital: Definition, meaning & purpose
What is Venture Capital?
It is a type of funding that comes with both high risk and reward, owing to the nature of a typical start-up.

They stay invested as long as the start-up holds potential. There have been instances where they bail out a start-up in financial trouble, among other things. Venture capitalists aim to maximize their returns.
Venture capital enables startups to scale their operations, develop innovative products, and expand their market presence. This form of funding is common in industries such as technology, biotech, fintech, and clean energy.
