Unlike small businesses, startups aim to disrupt entire industries

'Startups' can be defined as small, early-stage companies that are designed to grow fast.

According to some estimates, roughly 75% of venture-backed startups fail, making startups inherently risky ventures.

Working at a startup isn't for everyone, and is often more fast-paced than a run-of-the-mill job

Some argue that ideal startup employees have to be better than the average worker at managing uncertainty, acting with an "ownership" mindset rather than being a cog in the machine, and pushing limits.

Angel investors typically fund a startup at an earlier stage than venture capitalists

Angel investors and venture capitalists both invest in startups, but they differ in a few key ways. Angel investors typically invest earlier and in a smaller amount.

Startups fundraise in 'rounds' as they prove out their business and scale

When startups take on outside funding, those investments are divided into different "rounds." These rounds are catered to different stages in a startup's life cycle—a startup often needs different types of investors and amounts of funding at different stages of the business. For instance, a pre-seed investment round can include investments ranging from about $25K to $500K, whereas a Series D investment can be hundreds of millions of dollars.

The term 'startup'—which is typically used to describe private companies in their early stages of operation that focus on innovating new products or services to meet a market gap—can be traced back to a 1976 Forbes article.

Many startups in a variety of industries try to reframe themselves as 'tech companies'

Tech is still the dominant industry for startups—in part due to its low barriers to entry, high growth potential, investor preferences, and the proliferation of tech into a wide variety of industries. Sweetgreen, the fast-casual salad chain, for instance, has often referred to itself as a tech company.

Angels invest in a mix of startups from different industries

To diversify their portfolios and mitigate their risk, angels may invest in startups that are at earlier or later stages of development, as well as in various industries.

Platforms like AngelList help angel investors find startups to fund

Angel investors leverage their high net worths to fund seed-stage startups. While they could see high returns, investing in such an early company is a risk.

Angel investors often receive significant equity because of the risk they take

Angel investors fund startups at an early stage, at which time a company’s success is less assured. In exchange, they often ask for a significant equity stake.

Many startup founders pull out-of-the-box stunts to get their businesses off the ground.

Startup accelerators offer mentorship and seed funding in exchange for equity

Those programs, such as Y Combinator and Techstars, not only offer expert advice to founders, but also seed funding in exchange for equity. The goal is to help young startups learn from successful companies, making it more likely they attract venture capital.

Seed funding is often the first round of capital that a startup raises

Early-stage startups often try to secure seed funding from investors in order to take their idea from concept to reality.

Angel investors often come together as a syndicate

Startups raise money in different rounds from investors that include their friends and family, angels, and venture capital funds. These types of investors serve different purposes.

Startup accelerators that include more training activities, such as pitch competitions, tend to have better long-term success rates

That's according to a new study from Wharton. Y-Combinator, perhaps the most famous startup accelerator, currently has 16 alumni companies trading on the public market. But not every entrepreneur who joins a startup accelerator makes it big.

Venture capital is a type of financing that firms and funds use to invest in startups they believe have the potential for long-term growth

Household name companies such as Airbnb and Uber might not exist without venture capital, which is commonly referred to as "VC" for short.

The 50-100-500 rule: when a startup is no longer a startup

According to startup expert Alex Wilhelm, a company cannot be considered a startup if it generates revenue exceeding $50M, employs more than 100 people, and has a valuation of $500M or more. However, Wilhelm modified the rule in 2018 to $100M in revenue, over 500 employees, and a valuation of $2.5B or more.

80% of a VC firm's returns come from 20% of the deals, per VC's 'power law'

Early-stage startups are highly risky investments. Many companies in a VC portfolio will not provide any significant return.

In 2023, venture capital firms invested $170B in over 15,000 US companies

That's a significant drop from 2022’s $242B, reflecting market uncertainty but continuing VC’s role in scaling transformative ideas. Rooted in early risk-sharing models, venture capital took off with firms like ARDC in 1946, later evolving into today’s influential players like Sequoia Capital and Andreessen Horowitz.

Startup founders’ equity becomes diluted as they bring in more investors

When an angel investor funds a company in exchange for equity, startups issue new shares to them, rather than giving them existing shares, and boost the company’s valuation.

Y Combinator changed the way startups around the world are built

Many of the philosophies that the leaders of Y Combinator have infused into the program’s portfolio companies have become the playbook for building the next big thing, such as its focus on founder personality and more.

Explore the differences between private equity, venture capital, and hedge funds

Private equity firms focus on buying and improving private companies with the intent to sell them for profit or take them public. Venture capital is technically a form of private equity in which investors focus on startups and generally don't seek majority control of the company. Hedge funds are pooled investments for sophisticated investors that pursue a wide range of often complex strategies.

Global investing in startups hit a record $297B in Q1 2026

The level of startup funding around the world broke all previous records in Q1 2026 by a significant margin: Only $118B was raised in the previous quarter, and Q1's haul outpaced every full year of global VC activity before 2019. The increase was partly due to the enormous funding rounds from AI companies such as OpenAI and Anthropic.

Banks have increased small loan programs since 2018, upping competition for payday lenders

One of the reasons payday lending flourished for nearly two decades is that most banks charged high overdraft fees and didn't offer small loans. However, since 2018, banks have increased their small loan options. Supporters say this provides safer alternatives for consumers, as banks are subject to more regulatory measures and are less likely to allow consumers to keep rolling over loans.

Nonprofit VC funds invest in startups, but have donors instead of LPs

Examples include Andreessen Horowitz’s TxO (Talent x Opportunity) Initiative and Fifth Star Funds, which allows donors to write “Friends & Family” checks for Black tech founders.

The venture capital mindset is shaping the US into a 'portfolio state'

For decades, the US has operated as a low-regulation, private-sector-driven, globalized economy (also known as neoliberalism). In recent years, the Trump administration has taken direct stakes (rather than providing subsidies) in private companies with strategic products like semiconductors and rare earths. This paper argues the approach allows the US to capture the upside of growth.

It's difficult for individual investors to purchase IPO shares

Although the process of going public means the general public can invest in a company, the initial investment period is different. Before individual investors get in on the action, investment bankers sell the shares to larger financial institutions who can afford the asking price and risk associated with an IPO.
