Consentio

Full-stack SaaS platform for GDPR cookie consent management - visual banner designer, automatic cookie scanner, cookie-policy generator, consent analytics dashboard, Stripe billing, and Google Consent Mode v2 integration.

The Challenge

Most Czech businesses were stuck between two bad options: paying enterprise prices for tools like OneTrust or CookieBot (commonly $30–80/month per site), or settling for cheap plugins that required a developer to customize the banner. Meanwhile, Google Consent Mode v2 became mandatory for Google Ads and Analytics and most existing SaaS tools hadn't caught up. Something genuinely self-service, affordable, and v2-compliant didn't exist in this market.
