Webyn runs AI-guided A/B experiments across your pages — identifying winning variants in days, not months.
Traditional A/B testing requires guessing which variant to try next. Webyn uses a multi-armed bandit algorithm that continuously allocates traffic to better-performing variants, cutting test duration by up to 60%.
Webyn's engine analyzes your audience segments in real time and auto-selects the next hypothesis to test based on expected uplift — not gut feeling.
Forget waiting for statistical significance at fixed sample sizes. Webyn uses Bayesian updating to give you reliable conversion probability as traffic flows in.
Edit headlines, CTAs, hero images, and layout sections directly in the visual editor. Zero engineering time per experiment, once the one-line snippet is installed.
Connects to Google Analytics 4, Segment, Mixpanel, and Shopify out of the box. Conversion events flow straight into your existing dashboards.
Target experiments to specific cohorts — returning visitors, mobile users, traffic from paid ads, or custom attributes passed via the JavaScript API.
All experiment data is processed on EU infrastructure. No third-party cookies. Visitor anonymization is built in — not bolted on.
Getting started takes under an hour. Running your first experiment takes about twenty minutes.
Paste a single JavaScript tag before </body>. Webyn loads asynchronously — no impact on page speed scores.
Use the visual editor to create variants. Set the conversion goal — click, form submission, scroll depth, or a custom event.
Traffic is automatically allocated as data comes in. Webyn declares a winner when posterior probability exceeds 95% — no manual stopping required.
Webyn raised a €2.5M Seed Round led by Sharpstone Capital, a European VC focused on early-stage B2B software companies. The round closed in 2024 and is being used to expand the engineering team and accelerate product development.
