Self-improving

Dynamite reviews performance across all variants and personas, so each iteration gets better.

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 Dynamite editor: a Targets list grouped by page on the left, a live preview of a soda store's homepage with the headline outlined as the selected target, and a Variants panel on the right with the original, a returning-buyer version and a gift-shopper version.

Your visitors are unique, meet them where they are.

Questions

How is the topic selected?

From the articles this browser has read on your site and how the visit arrived. A reader with no clear topic gets your default prompt.

Can existing subscribers be excluded?

Reliably, only with subscriber status from a data connector you host. Without one, a version can exclude browsers that have reached your signup confirmation page.

How is signup confirmed?

Dynamite counts the form submit, or an event your code sends on success. Email confirmation is measured in your email tool.

Who is Dynamite for?

Any website whose visitors arrive wanting different things: online stores, SaaS and B2B sites, and publishers.

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.

Do I get help setting up?

Yes. Every account starts with an onboarding call, and we help you set up your first personalizations.

Are there guides?

We take you through setup on your onboarding call and share what works for sites like yours. Dynamite also bootstraps the first setup itself.

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.

Sell to every visitor like they are the only one.
