Knowledge as a Service

Diffbot's mission is to accelerate the advent of intelligent systems by building the first autonomous system capable of synthesizing human knowledge. We crawl the entire public web and operate the world's largest automated Knowledge Graph.

Our Values

We believe that democratizing access to a common knowledge base of facts will lead to more intelligent and trustworthy systems. We embrace growth, empowerment, empathy, original thinking, and aren't afraid to tackle big challenges.

State-of-the-Art Research

Our applied research team consists of the foremost experts in areas such as: structured document extraction, entity linking, relation extraction, coreference resolution, knowledge inference, knowledge fusion, and information retrieval.

Web-Scale Engineering

Diffbot runs its own crawl of the entire public web, independent from Google and Bing, on our own custom-assembled hardware, out of our own datacenter in California. We're one of the few places you can work on web-scale machine learning, distributed systems, and search engines in a fast-moving startup environment.
