Over the past few years, Web3 has grown quickly. What began with early blockchains and Bitcoin evolved into a much larger area that now includes blockchain infrastructure, DeFi apps, NFT platforms, and cryptocurrency exchanges. Offering users more control over their finances, data, and digital assets is the main goal of Web3.
Many businesses are now creating tools that allow this. Some focus on scaling and blockchains. Others focus on digital marketplaces, analytics, security, or trading. Together, they contribute to the functioning of the Web3 ecosystem.
What is Web3?
The next phase of the internet, known as Web3, is based on blockchain technology. Web3 promotes ownership and decentralization in comparison to Web2, where big platforms control user data and content. This means that users don’t need to rely on a central organization in order to manage their identities, hold their own digital assets, and engage directly with applications.
Public blockchains are used in Web3 to record actions and transactions. Without the use of middlemen, smart contracts execute applications automatically that comply with predetermined rules. This is how many cryptocurrency platforms, NFT marketplaces, and decentralized finance (DeFi) function.
What is a Web3 Company?
A Web3 company is a business that uses blockchain technology to build its products or services.
These businesses may develop blockchains, create cryptocurrency apps, manage exchanges, provide digital wallets, or offer developers tools. A lot of them implement tokens and smart contracts into their platform’s functionality.
There are Web3 businesses that are completely decentralized. Others use blockchain networks but function similarly to traditional businesses. Their primary services are built on digital assets and blockchain, which is what defines them as “Web3.”
Types of Web3 Companies
Web3 includes different types of companies based on what they build and how they support the blockchain ecosystem.
- Blockchain Platforms & Infrastructure: Companies that build core blockchain networks or scaling solutions that other apps run on.
- Decentralized Finance (DeFi) & Financial Services: Crypto exchanges, lending platforms, payment networks, and other services that handle digital assets.
- Security & Custody: Firms that protect digital assets, audit smart contracts, and provide secure storage solutions.
- Data & Analytics: Companies that track blockchain activity and provide market data, research, and risk analysis.
- NFT & Digital Asset Platforms: Marketplaces and platforms focused on NFTs, gaming assets, and digital ownership.
- Developer Tools & SaaS: Businesses that offer APIs, infrastructure, and software to help teams build blockchain applications.
Top 20 Web3 Companies
1. Binance
Launched in 2017, Binance is known as the biggest cryptocurrency exchange when it comes to trading volume, including both the spot and derivatives markets. Binance has a significant role in Web3, fintech, and cryptocurrency trading. Also, Binance announces that it has more than 300 million users worldwide and that its total product trading volume has reached $34 trillion, which helps to explain its high level of liquidity and reach.
Binance became successful because it didn’t stay “just an exchange.” Alongside spot, margin, and futures trading, it built a full product stack that keeps users inside one ecosystem: Launchpad and Launchpool for new token launches, Binance Earn for yield products, crypto loans, an NFT marketplace, and even a mining pool.
It also expanded into Web3 infrastructure through BNB Chain, and supports different user types with tools like the Web3 Wallet, Binance Institutional, and Binance Academy.
2. Crypto.com
Founded in 2016, Crypto.com is a global cryptocurrency platform with more than 80 million users and support for over 250 digital assets. Over the years, it has built a strong presence in retail crypto trading and digital payments.

Along with spot, margin, and derivatives trading, it also provides an NFT marketplace, staking and earning programs, and a DeFi wallet. Also, it helps onboard new users into cryptocurrency by offering educational content through its internal learning platform.
The Crypto.com Visa Card, which lets users spend cryptocurrency or fiat money directly, is one of its most well-known products.

Trading is available across many blockchains, such as Ethereum, Polygon, Arbitrum, Optimism, Base, Blast, and others.
OpenSea’s early move into the NFT market and broad network support are key factors in its success. Being one of the first significant NFT marketplaces, it drew creators and collectors before the market became crowded with rivals.
