Drawbridge

Drawbridge, Inc. was a San Mateo, California cross-device identity and digital advertising company founded in 2011 by Kamakshi Sivaramakrishnan (a former AdMob scientist). It built a people-based identity graph that used machine learning to probabilistically match individuals across their connected devices (desktops, smartphones, tablets, and connected TVs) so brands could serve and measure relevant advertising across devices. Backed by Kleiner Perkins, Sequoia Capital, Northgate Capital, and Mitsui & Co., the company raised roughly $69M across five rounds before it was acquired by LinkedIn in 2019 and folded into LinkedIn Marketing Solutions. Drawbridge no longer operates as an independent company and never published a public developer API or developer portal, so there is no live API surface to enrich; this profile records its identity as a historical Kleiner Perkins portfolio company.

Drawbridge is profiled on the APIs.io network. Tagged areas include Company, Enterprise, Advertising, Identity, and Cross-Device.
