0x Labs Decentralized P2P trading

0x began in October 2016 when Will Warren (a UC San Diego mechanical/structural engineering researcher who had been a Los Alamos National Laboratory graduate research assistant) and Amir Bandeali (a former Chopper Trading trader with a finance degree from the University of Illinois Urbana-Champaign) started building an open protocol for peer-to-peer trading of Ethereum-based tokens. They published the '0x: An Open Protocol for Decentralized Exchange on the Ethereum Blockchain' whitepaper in February 2017, describing an off-chain order-relay/on-chain settlement architecture meant to let any developer build a decentralized exchange without deploying custom matching/settlement logic. A third co-founder, Alex Q. Xu, is also credited on Crunchbase, though public information about his subsequent role is limited. On August 15, 2017, the team raised roughly $24 million in a public token sale of ZRX (500 million tokens, 50% of total supply, at $0.048/token, implying a ~$48M pre-sale valuation), backed by Polychain Capital, Pantera Capital, Blockchain Capital, and FBG Capital -- one of the larger and more prominent ICOs of the 2017 boom. ZRX functions as a governance token for the 0x DAO/protocol and (historically) a fee token for protocol relayers.

For its first few years 0x operated primarily as an open-source protocol development team, iterating through several protocol versions (culminating in 0x Protocol v4) and supporting third-party 'relayers' that built exchanges on top of the 0x order-matching standard. In June 2020, the core team incorporated 0x Labs as a distinct commercial entity to build products and services on top of the increasingly community/DAO-governed 0x Protocol, while continuing to decentralize protocol governance itself (ZRX holders can vote on protocol upgrades, or ZEIPs). 0x Labs' first flagship consumer product, Matcha, launched around this time as a liquidity search engine/DEX aggregator, and the company also stood up Periscope Trading as an in-house market-making arm. Amir Bandeali transitioned from Co-Founder & CTO to Co-CEO (alongside Warren) in September 2020.

0x Labs subsequently pivoted its commercial focus toward B2B infrastructure: the 0x API (later rebranded Swap API) became the primary product, aggregating liquidity across 100+ DEXs and, eventually, 16+ blockchains, and was adopted by major wallets and exchanges including Coinbase, MetaMask, Brave, Zapper, and (from July 2022) GameStop's self-custodial wallet. The company raised a $15 million Series A on February 5, 2021, led by Pantera Capital with participation from Jump Capital, Nima Capital, Blockchain.com Ventures, Nascent Ventures, Coinbase Ventures, IOSG Ventures, and DeFi Alliance -- by then the protocol had already processed over $15B in cumulative volume across 250,000+ traders. On April 26, 2022, 0x Labs announced a $70 million Series B led by Greylock Partners, with participation from Pantera Capital, Sound Ventures, A.Capital, Jump Crypto, OpenSea, Coinbase, Brevan Howard, IOSG Ventures, Reid Hoffman, and actor/investor Jared Leto -- at the time the company had facilitated $158B+ in tokenized value across 43M+ trades and 3.5M+ active users. Cumulative facilitated volume passed $180B by lifetime totals cited in a 2026 Coinbase case study, with 211M+ transactions processed and Coinbase alone routing hundreds of millions in swap volume through 0x's rails across its Exchange app, Base App, and Developer Platform.

Business model

Provides open-source protocol infrastructure (0x Protocol) plus commercial, monetized developer APIs (Swap API, Cross-Chain API, Gasless API, Trade Analytics API) that wallets, exchanges, and applications integrate to power on-chain token swaps; also operates Matcha, a consumer-facing DEX aggregator/trading app, and Periscope Trading, a market-making arm.

Per-transaction/percentage-based fees on swap volume routed through its APIs (configurable monetization for integrators), plus fees generated from its own consumer products (Matcha) and market-making activity (Periscope Trading).
