LinkedIn closed on its acquisition of employment engagement and retention platform Glint. The acquisition extends LinkedIn’s offerings to include visibility into the overall health and productivity of the people within an organization, as well as recruitment strategies.

LinkedIn first announced the deal in October.

Glint was acquired by LinkedIn for a company-reported $400 million, although multiple news entities are reporting the acquisition actually totals more than $500 million, according to Silicon Prarie News. The acquisition occurred earlier in the quarter, and it is the largest acquisition by LinkedIn since its own acquisition by Microsoft for $26.2 billion in late 2016.

Glint is based in Redwood City, Calif., with offices in London, UK, and Lincoln, Neb. The firm has more than 300 customers globally using its enterprise-grade, AI-driven platform. Its client firms include United, Intuit and Commercial Bank of Dubai.
