R2B2 provides programmatic advertising monetization for online publishers. It works with publishers through tag-in-tag integration or Prebid and connects them to 24 SSP demand sources, according to its website.

Its customers are large and mid-sized online publishers, which it serves through a commission-based monetization partnership; the website does not state pricing terms beyond an estimated-revenue calculator. The website cites over 3000 sites, more than 2.5 billion impressions sold monthly, and client references from Czech and Slovak media groups.

The company was founded in the Czech Republic in 2014 (the registry lists 2019 as the legal entity founding date), expanded to Slovakia in 2018, and operates in 46 countries. A majority stake was acquired by the Genesis Capital Growth fund in 2020, and in 2025 it bought 100% of Caroda, a video advertising technology company. Its headquarters are listed in Prague, and the website lists sales and account contacts; no hiring information is given.

Product: Programmatic advertising monetization service and proprietary ad technology for publisher websites, including video ad technology via Caroda.
