Trolltech 1994–2007 Trolltech was founded by Eirik Chambe-Eng and Haavard Nord on 4 March 1994. The duo started writing Qt in 1991; since then, Qt has steadily expanded and improved. In 2002, Trolltech introduced
Qtopia which is based on Qt. Qtopia is an application platform for
Linux-based devices such as mobile phones, portable media players, and home media. It is also used in many non-consumer products such as medical instruments and industrial devices.
Qtopia Phone Edition was released in 2004, and their
Greenphone smartphone is based on this platform. Trolltech completed an
initial public offering (IPO) on the
Oslo Stock Exchange in July, 2006. The total cost for Nokia was approximately €104 million. On 5 June 2008 Nokia's voluntary tender offer was approved for all the shares in Trolltech. By 17 June 2008, Nokia had completed its acquisition of Trolltech. On 30 September 2008, Trolltech was renamed as Qt Software, and Qtopia was renamed as
Qt Extended. On 11 August 2009, the company's name was changed to Qt Development Frameworks. The Qt environment was a key part of the company's strategy until 2011, when Nokia decided to switch to
Windows Phone OS for its smartphones.
Part of Digia 2012–2016 Nokia sold the commercial licensing business of Qt to Digia in March 2011. The following year, Digia acquired the entire Qt development environment and related business from Nokia. As a result of the acquisition, Digia became responsible for all of the functions related to Qt technology, including product development. The main goal of the acquisition was to strengthen Digia's position in the Qt ecosystem and expand the availability of Qt technology across a growing number of platforms. In September 2014, Digia formed The Qt Company, a wholly owned subsidiary dedicated to the development and governance of the Qt platform. In connection with this, the website qt.io went live, combining the
open source qt development and commercial Qt functions that had previously operated at different addresses. Qt products had some 800,000 users globally. In August 2015, Digia Plc's Board of Directors began to explore the
demerger of Digia’s domestic businesses and the Qt businesses into two separate listed companies.
Qt Group 2016–current In May 2016, the company went public on
NASDAQ Helsinki as QTCOM. In March 2016, Digia Plc's Annual General Meeting resolved on the partial demerger of Digia and the demerger was registered in the trade register on May 1. Digia’s Qt business was transferred to a new company, named Qt Group, and Digia's domestic business segment remained under the Digia brand. Digia’s CEO Juha Varelius was appointed as the CEO of Qt Group. In 2018, the company had 5,000 customers. Approximately 80% of the
Fortune 500 companies are customers of Qt Group. The company attracted the interest of international investors in spring 2020 when its
market capitalization rose above 500 million euros. The company's market capitalization exceeded 1 billion euros in October. The share price had risen by more than 700% from the IPO price. The company's net sales were close to EUR 80 million euros and its earnings were approximately 17 million euros. By spring 2021, the company’s share price had grown nearly fivefold over a period of one year, In August, the company made it to the
OMXH25 index. The company's net sales amounted to 121 million euros and it had 455 employees. In the fall of 2022, the company announced that it would acquire Axivion, a Germany-based company whose products detect issues that erode the quality and performance of software, i.e.
static program analysis, among other services. ==Organization==
