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.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
Drawbridge is tracked in the API Evangelist network. This page is the human-readable profile that sits on top of the machine-readable index we maintain at apis.io.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Drawbridge scores 6.8/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

Drawbridge is in the network as a tracked entity. We haven't yet indexed a public API surface for it — when one is published, the artifacts, score, and agent-readiness read will appear here automatically. The source repository is where that profile is built.
