In January 2024, a French e-commerce site received a €150,000 GDPR fine. Not for a data breach — just for loading Google Analytics before getting cookie consent. The fine was 10x their monthly revenue. This isn't rare: EU data protection authorities issued 2,000+ fines in 2023, and cookie consent is the lowest-hanging enforcement fruit.
CookieBot (by Usercentrics) dominates the market at $39-199/mo and was acquired for €100M+. CookieYes ($10-45/mo) and Osano ($99-399/mo) compete for enterprise. But the experience of adding cookie consent to a website is still terrible — most tools require manual cookie classification, complex configuration, and generate banners that look like they were designed in 2015.
The gap: a modern consent manager that auto-scans your site for cookies, auto-classifies them (analytics, marketing, functional), generates a beautiful banner that matches your site's design, and blocks scripts until consent. Install with one script tag, configure in 5 minutes. At $9-29/mo, it undercuts CookieBot significantly while offering a better developer experience.
💰 Revenue Blueprint
Three-tier value ladder to monetize from day one
1 site, basic banner, auto-detect cookies, 10K pageviews/month, powered-by branding
1 site, 100K pageviews, custom branding, auto-blocking, consent analytics, privacy policy generator
10 sites, unlimited pageviews, A/B test banners, advanced analytics, Google Consent Mode v2, API, no branding
Why Now?
EU Digital Markets Act added new consent requirements in 2024. Google requires Consent Mode v2 for EU ad tracking. California, Virginia, Colorado all passed state privacy laws. Compliance demand is accelerating.
📊 Market Evidence
The Market Gap
CookieBot ($39+/mo) is expensive and complex. CookieYes ($10/mo) is cheaper but limited auto-detection. No tool combines auto-scanning + beautiful banners + Google Consent Mode at $9/mo.
