About Dynamite

Dynamite personalizes your website for every visitor in under 300ms, so they see what is most likely to convert. It installs on ANY website with one line of JavaScript and typically increases conversion rates by ~20%. Dynamite uses browsing behavior, campaign context and connected customer data to select the right combination of approved content. You control the designs and what can change, through the dashboard or your AI agents via MCP. Dynamite is used across e-commerce and B2B, personalizing across messaging, customer stories, CTAs, product listings, imagery, and more. No two buyers have the same exact reasons for buying, they should see different content. Dynamite grew out of our work building ion.design, helping companies design and improve their websites autonomously with agents.
