A spin-off company of Kainos was established in 1994 called Lagan Technologies, which grew to become a software supplier into local government in the UK and the US. It was eventually acquired by U.S. based Kana Software in 2010.[10]
By 1997, due to the expansion of the company, Kainos relocated and opened offices in Mount Charles, Belfast, and opened its main headquarters in Upper Crescent, Belfast.[11]
After several years of business, in which Fujitsu was its main customer, the company sold most of its stake to ACT Venture capital in 2000.[12] ACT Venture capital later divested its shareholding in Kainos.[13]
In September 2004, Kainos entered into a partnership agreement with Mediasurface, the UK's largest content management provider.[14] The following year, Kainos entered into another partnership agreement in 2005 with TIBCO, a provider of infrastructure software.[15]
In 2007, a wholly owned subsidiary of Kainos called SpeechStorm was established, providing automated products for call centres, including touch tone, SMS, speech and visual IVR.[16][17] That same year, management in Kainos bought out Fujitsu's remaining 20% shares.[12]
Kainos expanded its operations and opened a research office in Silicon Valley on 18 October 2010.[18]
On 19 November 2014, Kainos announced its plans to expand the Evolve Electronic Medical Records platform into Ireland.[19]

As part of an extension of its US operation, in June 2020, Kainos announced plans to create 133 jobs in Indianapolis. The plans included expenditure of £650,000 to build new facilities in the area, marking the first venture into the US Midwest.[20]
Kainos bought a property on Dublin Road in Belfast in 2019 and received planning approval to build 250,000 ft2 of office space there. However, in light of the rapid expansion of flexible work during the Covid-19 pandemic, it sold 60% of that site, and committed instead to building 75,000 ft2 over 12 storeys, of which it would occupy four and lease out seven to third-party tenants via its subsidiary, Bankmore Investments. Completion was planned for 2027.[21]
Kainos announced in March 2025 that it would lay off 190 of its 3,000 staff.[22]
