TechCrunch Disrupt is an annual conference hosted by TechCrunch in San Francisco,  New York City,  and Europe (London or Berlin),  which began in 2011 and is where new technology startups launch their products and services competing on stage in front of venture capital potential investors, media and other interested parties for prize money and publicity.

TechCrunch operated Crunchbase from 2007-2015, a database of the startup ecosystem consisting of investors, incubators and start-ups, which comprises around 500,000 data points profiling companies, people, funds, fundings and events. The company claims to have more than 50,000 active contributors. Members of the public, subject to registration, can make submissions to the database; however, all changes are subject to review by a moderator before being accepted. Data is constantly reviewed by editors to ensure it is up to date. In 2013, Crunchbase claims to have 2 million users accessing its database each month. 
AOL is in dispute with start-up Pro Populi over that group's use of the entire Crunchbase dataset in apps that Pro Populi has developed, one of which is known as People+. Pro Populi is being represented by the Electronic Frontier Foundation. 
In 2015, Crunchbase spun out of AOL/Verizon/TechCrunch to become a private entity, and is no longer a part of TechCrunch. 
In 2008, TechCrunch started The Crunchies award ceremony, which celebrates the "most compelling startups, internet and technology innovations of the year".  Techcrunch often creates a list of the top startups and the funding they received. Twelve categories have been awarded in 2016, including "Best New Startup", "Best Overall Startup", and "Best Mobile App".  2016 was also the first year awarding the Diversity Award. 
In 2014, TechCrunch Disrupt was featured in an arc of the HBO series Silicon Valley.  The characters' startup "Pied Piper" participates on a startup battle at TechCrunch Disrupt.  According to TechCrunch editor Sam O'Keefe, the show's representation of the conference was "obscenely accurate". 
In 2011, the site came under fire for possible ethics violations. These included claims that Arrington's investments in certain firms which the site had covered created a conflict of interest.  The controversy that ensued eventually led to Arrington's departure, and other writers, including Paul Carr and Sarah Lacy, followed suit.
