Product · Tandem

Co-shopping, the way it should have always worked.

Tandem is a synchronized commerce session — one customer, one advisor, one AI concierge, one shared catalog state. Each side keeps their own device, their own session, their own privacy. The conversation moves through products like a real shopping appointment — not a Zoom call dressed up as a checkout.

Featured product · Tandem

Two people.
One purchase.
Synchronized.

Tandem is the co-shopping layer for high-consideration commerce. Not screen sharing — synchronized state. The advisor and the customer see the same catalog, the same configurator, the same price breakdown — each on their own device, each in control of their own actions.

  • Synced state, not shared screens
    Each side keeps their own session. State replication via WebSocket. No bandwidth waste, no privacy mess.
  • AI concierge with full context
    Catalog, customer profile, brand-tone guardrails. Suggests products the advisor can approve, modify or override.
  • Suggest / approve workflow
    Advisor never gives up control. AI proposes, advisor curates. The end result is a hand-built selection at machine speed.
  • Auditable session record
    Every Tandem session is a governed event in Renaissance OS. Replay, KPI it, learn from it.

How it differs

Live chat is not Tandem.

Most platforms layer a chat plugin onto a single-user storefront and call it clienteling. Tandem is the storefront — restructured around a two-person session. The customer isn't watching the advisor's screen. They're shopping, with an advisor and an AI both contributing in real time, with full audit trail.

Why it matters

High-AOV deserves shared deliberation.

Average jewelry order values run from hundreds to tens of thousands. A solo browse is the wrong unit of analysis. Tandem matches the actual decision pattern — couples deliberating an engagement, families choosing an heirloom, friends sourcing a gift — and gives the brand the same structural advantage a great in-store advisor provides.

Anatomy of a session

From advisor invite to closed sale, in one governed thread.

  1. 01

    Invite

    Advisor sends a Tandem link. The customer opens it on their device, where they are — couch, café, or 9,000 km away.

  2. 02

    Sync

    Catalog state replicates over WebSocket. Both sides see the same shortlist, configurator, and price breakdown — independently navigable.

  3. 03

    Suggest

    AI concierge proposes options based on the customer's vector profile and the advisor's brand-tone guardrails. Advisor approves what surfaces.

  4. 04

    Close

    Order placed in-session. Full audit trail — every suggestion, every approval, every change — committed to Renaissance OS for KPI measurement.
