Detailed Review
Convertize's pitch is unusual for this category: rather than assuming you already know what to test, it ships more than 150 documented A/B testing ideas grounded in consumer psychology research, so a marketer without a hypothesis can start from a library instead of a blank page.
Autopilot mode, a multi-armed bandit, reallocates traffic to the better-performing variant automatically, and a Hybrid statistical engine is meant to shorten how long a test needs to run before it is trustworthy. It sits alongside Kameleoon, AB Tasty and Varify.io as a straightforward client-side testing tool with a visual SmartEditor, not a feature-flag system.
Convertize Ltd has been registered in the United Kingdom since 10 September 2008, company number 06694068, currently listed at 12 Hammersmith Grove in London.
Pricing is published rather than quoted: the Solo plan is £45 / €49 / $59 a month for up to 20,000 visitors and three projects, and the Team plan starts at £175 / €199 / $249 a month for up to 100,000 monthly visitors, rising with traffic to £759 / €899 / $999 for up to 2,000,000 visitors, with two months free on annual billing. A 14-day free trial needs no card.
Two gaps are worth flagging. The United Kingdom sits outside the EEA under an adequacy decision rather than inside it, which for some European buyers is a material difference. And while the privacy policy places its databases and servers within the European Union, held by Convertize or by equivalent third-party providers, it names neither a provider nor a country.
