Winning complex business is hard. Tenders arrive with hundreds of requirements and immovable deadlines. Dozens of experts across departments and locations need to contribute at once. Content gets reused without control, compliance risks slip through under pressure, and quotes for configurable products take days when customers expect them in hours. Xait helps companies in energy and renewables, construction, and manufacturing solve exactly that. We bring structure to the bid and proposal process so large teams can work together without chaos, so experts spend their time on what wins and not on formatting and chasing input, and so every proposal and quote is accurate, compliant and on brand. Our agentic AI reads incoming tenders, extracts requirements and flags risks early, all within a secure environment your data never leaves. Founded in Stavanger in 2000, Xait today supports more than 300 companies and 70,000 users worldwide, from offices in Norway, Germany, the UK, the US, France and India.
