A visitor arrives. Dynamite reads where they came from as the page loads.

Built for your agents

Dynamite can be driven entirely over MCP, so your agents create, manage, and optimize personalization themselves. Or open the hood and control everything yourself.

Three Linden hero variants, labeled Gift buyer, Bundle buyer, and New visitor, fan out from the Dynamite editor with thin gold lines connecting them to its Variants panel.

Self-improving

Dynamite tracks everything: every variant shown, every visitor, and who converts from what. It builds that into its own memory, so the decisions get better every single week.

Connect your own data and de-anonymizers for more granularity, or let it learn from browsing patterns alone.

You keep control

Dynamite doesn't generate new designs on the fly. You configure the possible designs on our dashboard, along with who they are for. The rapid intelligence engine decides who sees what when visitors show up.

The Dynamite editor: a Targets list grouped by page on the left, a live preview of the Linden homepage with the headline outlined as the selected target, and a Variants panel on the right with the original and a returning-buyer variant.

Questions

Do I need to redesign anything or migrate?

No. It works with any website out of the box.

How long until I see results?

You should be implemented in a day and start seeing results within a week.

How much management does it take?

Dynamite can bootstrap the implementation and drive itself. The more data you give it, the better it gets. If you want to hold control over exactly what is shown and when, you can. Otherwise, the agents are good at it.

Will it affect my page speed?

No. Dynamite runs at runtime, after your page has painted.

Where does the data live?

In a cookie in the visitor's browser, backed up and enriched on a server.

What can be changed?

Dynamite can be pointed at any component or control to replace sections, add new ones, reorder, filter, and more.

How fast is it?

Dynamite caches variants, so the decision engine can render new content within 300 ms.
