Terms of the deal were not disclosed.

L2 offers brands an annual subscription service allowing brands to benchmark their digital presence against key competitors, as well as giving them access to reports and events.

The company, which employs around 150 people in New York and London, will initially continue to operate independently, while Gartner focuses on integrating CEB, the HR-focused research business that it acquired in January for $2.6 billion.

The acquisition of L2 is expected to be completed by the end of March.
