|Autonomy Corporation headquarters at Cambridge Business Park.|
Autonomy Corporation is a multinational enterprise software company founded in Cambridge, United Kingdom in 1996. It is a subsidiary of Hewlett-Packard. The company has joint headquarters in Cambridge, UK and San Francisco, USA.
The company uses a combination of technologies born out of research at the University of Cambridge. It develops a variety of enterprise search and knowledge management applications using adaptive pattern recognition techniques centered on Bayesian inference in conjunction with traditional methods.
Autonomy was acquired by Hewlett-Packard (HP) in October 2011. The following year, HP wrote off $8.8 billion of Autonomy's value, claiming that a serious accounting scandal was found at the company.
Inception and expansion : 1996 - 2011 
Autonomy was founded in Cambridge, England by Dr. Michael Lynch, David Tabizel and Richard Gaunt in 1996 as a spin-off from Cambridge Neurodynamics, a firm specializing in computer-based finger print recognition.
In July 2007 it acquired Zantaz, an email archiving and litigation support company, for $375m.
On 5 May 2011 the Mercedes GP Formula One team announced an $8 million sponsorship deal with Autonomy, and on 8 July 2010 Tottenham Hotspur FC announced a two year sponsorship deal with Autonomy for their Premier League kit. For the 2011-12 season Spurs' Premier League shirt will feature Autonomy's Augmented Reality technology Aurasma.
As a Hewlett Packard company: 2011 - Present 
On 18 August 2011 Hewlett Packard announced that it would purchase Autonomy for US$42.11 per share, around $10.2B. The transaction was unanimously approved by the boards of directors of both HP and Autonomy and the Autonomy board recommended that its shareholders accept the offer. On 3 October 2011 HP closed the deal with over 87% of Autonomy shares acquired.
In May 2012 Mike Lynch left his role as Autonomy CEO after a significant drop in revenue in the previous quarter.
In November 2012 Hewlett-Packard announced that it was taking an $8.8 billion accounting charge, after claiming “serious accounting improprieties” and “outright misrepresentations” at Autonomy. However, Mike Lynch counter-alleged that the problems were due to HP's running of Autonomy, citing "internecine warfare" within the organization.
The main technology, 'Intelligent Data Operating Layer' (IDOL), allows search and processing of text taken from database, audio, video or text files or streams. The processing of such information by IDOL is referred to by Autonomy as Meaning-Based Computing.
Autonomy's technology attempts to "understand" any form of unstructured information, including text, voice, and video, and based on that understanding perform automatic operations, for example inferring what the user wants and on that basis finding other information that may be of interest.
On 29 November 2011, HP announced a new big data analytics platform, "HP Next Generation Information Platform", based on a combination of Autonomy’s unstructured data analytics engine, IDOL 10 and Vertica's fast-loading, real-time analytics database. This strategic move by HP is part of its refocus on enterprise software, and enterprise integration solutions and services. The platform will combine structured data with unstructured information - which comprises about 80% of the data on the web such as video, pictures, emails etc.; and handle them in a unified manner.
Autonomy has over 400 OEM partners, more than 400 vendors and integrators, and over 20,000 customers, including BP, Halliburton, Royal Dutch Shell, BAE Systems, AstraZeneca, United States Department of Defense, United States Department of Homeland Security, Citigroup and Symantec.
Autonomy has twin head offices in Cambridge, UK, and San Francisco, USA, major offices in the US, the UK, Canada, France, Japan, Australia, Singapore, Germany, and smaller offices in India and throughout Europe and Latin America.
Senior management 
Many of Autonomy's senior executives left after the acquisition by Hewlett-Packard, "amid accusations that HP is too bureaucratic, and counterclaims that Lynch and his team failed to deliver on revenue targets". The membership of the company's management team at any time is available on the company Web site.
