What is OpenKit?

OpenKit is a UK-based AI and software development agency founded in 2019, headquartered in Durham with additional presence in London and Cambridge, and a very small team of just 2–10 people. Despite its size, it holds ISO 27001 and ISO 9001 certifications and is Cyber Essentials certified — independently verifiable security credentials unusual for a micro-agency, serving legal, healthcare, education, financial services, and manufacturing SMEs and mid-market businesses across the UK.

OpenKit works primarily with clients in Healthcare, Financial Services, Manufacturing sectors. Its primary differentiator is: ISO 27001, ISO 9001, and Cyber Essentials certifications at a 2–10 person micro-agency scale — unusual security rigor for its size.
