Ahrefs

Ahrefs was founded in 2010 by Dmytro Gerasymenko and is headquartered in Singapore. The company builds software for search engine optimization, providing tools that track backlinks, organic search rankings, and keyword data.

Its core products include Site Explorer, Keywords Explorer, Site Audit, and Rank Tracker, used by marketers, SEO professionals, and content teams to analyze websites and competitors. Ahrefs maintains its own web crawler and large index of backlink and search data, which underpins its analytics tools. The company also publishes SEO research and educational content through its blog and YouTube channel.

Ahrefs has grown without external venture funding, remaining privately held and bootstrapped since its founding. It has expanded internationally with offices beyond Singapore and built a large customer base among digital marketers and businesses of varying sizes.
