We believe every word matters
Copysplit helps marketers stop guessing and start testing. We're building the tools that turn copy into a competitive advantage.
Our Story
Copysplit started in 2024 when our founders — a conversion rate optimizer and a machine learning engineer — realized that most marketers were still writing copy based on gut instinct. Despite having access to sophisticated analytics, A/B testing copy remained slow, technical, and expensive. Only companies with dedicated engineering teams could run proper copy tests.
We set out to change that. We built a pixel-based testing engine that lets anyone — from solo marketers to 50-person teams — launch copy A/B tests in minutes, without touching a line of code. Then we added AI-powered copy generation that doesn't just spit out generic text, but learns from your conversion data to suggest variations that are statistically more likely to win.
Today, over 500 marketing teams use Copysplit to test their headlines, CTAs, and body copy across thousands of sites. Our users have run more than 50,000 tests and measured the impact on over 10 million visitors. The average conversion lift? 34%. We're just getting started.
What we stand for
Data over guesswork
Every copy decision should be backed by real conversion data, not opinions or best practices from 2015. We build tools that make testing easy enough that there’s no excuse not to test.
Built for speed
Marketers move fast. Our pixel installs in 30 seconds, tests launch in minutes, and results are statistically validated automatically. No waiting for developers, no complex setup.
Team-first
We built Copysplit for teams managing multiple sites and campaigns. Multi-site dashboards, shareable reports, and team collaboration aren’t add-ons — they’re core to the product.
