What Performax does

Performax (legal entity Performax.cz, s.r.o.) is a Czech ad-technology company headquartered in Prague that operates the proprietary Performax Yield platform to help media publishers optimize and monetize their website advertising inventory. The company's core offering is its own ad serving technology and programmatic advertising systems, including a device identification layer (px2uid, stored via cookies and localStorage for 13 months), session management, ad-slot frequency controls, A/B testing, ad sequencing, and pause/refresh controls. The platform integrates with more than 20 global programmatic partners — Google Ad Manager, Adform, Criteo, Magnite, OpenX, PubMatic, Teads, Xandr, Index Exchange, Seznam SSP, RTB House, and others — enabling publishers to access broad demand through a single managed stack. All technology is tested on the company's own publishing properties before client deployment.

Performax operates as part of the Dignity media group, which includes publishing houses, media representation services, and an anti-ad-blocking platform. This group structure provides the company with hands-on publisher experience, internal product validation, and distribution credibility in the Czech and Central European market. The company serves enterprise media publishers including Czech News Center a.s., FTV Prima spol. s r.o., Seznam.cz a.s., and ARBOmedia, and is GDPR- and CCPA-compliant for data handling.

The business model is a sales-led, direct-to-publisher motion generating revenue primarily through transaction fees (a share of advertising revenue earned from serving ads on publisher websites) supplemented by managed services for ad-serving technology implementation. Pricing is quote-based and not publicly disclosed. Geographically, Performax focuses on the Czech Republic and Central Europe, with stated intent to expand internationally, and operates with a headcount of 11–50 employees.
