Automatically extracts and structures data from web pages into usable formats.

Diffbot, founded in 2008, is a Menlo Park-based company specializing in automated web data extraction and knowledge graph construction. The company initially bootstrapped its technology by focusing on single-page extraction, launching APIs for developers to extract structured data from URLs. This approach attracted early clients like AOL, Instapaper, and Snapchat.

Diffbot later integrated Gigablast's search engine technology to scale its crawling capabilities, leading to the development of Crawlbot, a tool for custom web crawls. The company's flagship product, the Diffbot Knowledge Graph, autonomously structures publicly available web data into entities like organizations, news articles, and retail products. As of 2025, Diffbot serves over 400 companies, including enterprise clients in finance, consumer goods, and media.

The company has raised $2 million in seed funding from notable investors like Sky Dayton and Andy Bechtolsheim. Diffbot's privacy policy, updated in August 2025, outlines its data handling practices for web-crawled information. The company continues to focus on automating the interpretation of complex, interconnected datasets, positioning itself in the growing knowledge graph market projected to reach $9.88 billion by 2032.
