At Blekko, our mission is to create a differentiated search experience by delivering high quality, curated results and organizing content into categories. Our sophisticated search technology powers our suite of products – a web search engine, mobile app, and social news platform.


Blekko’s proprietary technology operates on a unique system that intersects our own original search index, Dynamic Inference Graph (DIG) algorithm, and editorial evaluation. Using the text from the Web stored in our datacenter, we distill the text and links down to a small semantic database, and use that database to map queries to a large list of editorially-crafted slashtag filters.
