Crunchbase is a platform for finding business information about private and public companies.
Crunchbase information includes investments and funding information, founding members and individuals in leadership positions, mergers and acquisitions, news, and industry trends. Originally built to track startups, the Crunchbase website contains information on public and private companies globally.
Crunchbase sources their data in four ways: the venture program,  machine learning, an in-house data team, and the Crunchbase community. Members of the public can submit information to the Crunchbase database. These submissions are subject to registration, social validation, and are often reviewed by a moderator before being accepted for publication.
Crunchbase was originally founded in 2007 by entrepreneur Michael Arrington, as a place to track the startups that parent company TechCrunch featured in articles. From 2007 to September 2015, TechCrunch maintained control of the Crunchbase database.
In September 2010, AOL acquired TechCrunch and subsequently Crunchbase as one of TechCrunch's portfolio companies. In November 2013, AOL was in dispute with start-up Pro Populi over the company’s use of the entire Crunchbase dataset in apps that Pro Populi developed. One of these apps, known as People+ Pro Populi, was represented by the Electronic Frontier Foundation. 
In 2014, Crunchbase added incubators, venture capital partners, and a new leaderboard feature to the startup database. 
In 2015, Crunchbase separated from AOL/Verizon/TechCrunch to become a private entity.  In September 2015, in conjunction with the spin out, Crunchbase announced $6.5 million in funding raised from Emergence Capital.  This was shortly followed with a follow-up round of $2 million in November 2015.
In 2016, the company rebranded from CrunchBase to Crunchbase and launched their first product: Crunchbase Pro. 
In April 2017, Crunchbase announced an $18 million Series B from Mayfield Fund.  At the same time, Crunchbase launched two new products – Crunchbase Enterprise and Crunchbase for Applications. 
In 2018, Crunchbase launched Crunchbase Marketplace. 
- Crunchbase Pro
- Designed for Crunchbase power users, this tool offers more advanced search capabilities, market trend analytics, and alerts to track industries, people, companies, and investors.
- Crunchbase Marketplace
- Marketplace allows users to search and analyze companies with integrated third-party data sources. Alongside Crunchbase company information, users can access additional data like web traffic, tech stack, IT budgets, and more.
- Crunchbase Enterprise
- This tool lets users perform typical business intelligence and analytics queries, such as setting up and following investment trends, identifying and tracking growth industries, and identifying companies that are close to their own. Crunchbase Enterprise could be described as the “large-company” version of Crunchbase Pro. 
- Crunchbase for Applications
- This tool allows users to integrate Crunchbase data into their product, providing their customers the ability to automatically contextualize prospects to prioritize their sales pipeline and identify key buy signals.
Crunchbase has more than 560,000 active community contributors on the platform. Over 5 million users access the Crunchbase website each month.
