Pack
Personalization

Where winning experiences run.

Pack is the personalization runtime for your storefront. Playbook validates what converts; Pack is where you build that personalization in — server-side, audience-aware, real-time — for the right shoppers.

Pack personalization runtime

The runtime, not the test.

Server-side, no flicker

Personalized experiences render at the edge before the page reaches the shopper. No client-side swap, no flash of the wrong variant, no CLS penalty.

Server-side personalized delivery

Audience-aware by default

Every experience is aware of cohort, source, and behavioral signal. Returning subscriber, first-time paid-social visitor, high-intent PDP browser — each sees the experience that fits them.

Audience-based personalization

Build in what wins in Playbook

Every test Playbook runs produces a clear winner for a cohort. Take that result into Pack and build it into a live personalized experience — no page builder, no dev cycle. Playbook validates, Pack runs.

Winning experiences from Playbook flow into Pack

The full loop.

FAQs

Questions about Pack's personalization runtime? We're here to help.

  • Playbook lets brands quickly test messaging and content to see what converts best for each audience. Pack lets you build that personalization in as a core part of your storefront experience.

  • Every personalization is decided at the edge before the page renders. Shoppers get the right variant on first paint. No client-side swap, no flash of unstyled content, no layout shift.

  • Cohort membership (behavioral, subscription state, LTV tier), traffic source (campaign, organic, referral), and real-time context (device, page history, cart state). All available in the same audience model your team already uses.

  • No. Pack's runtime can serve personalizations authored anywhere — your team, agents via MCP, or Playbook. Playbook is the fastest path to producing validated ones.

  • Yes. Pack's MCP server exposes tools for agents to create audiences, propose experiences, and promote winners — all landing in a release your team reviews before shoppers see them.
