8 products. One account.

The thesis

One substrate. Every product reads from it.

One identity, one family graph, one address book, one consent ledger, one WhatsApp-native notification mesh. Built once, then shared across the whole portfolio.

  1. 01

    One identity, every product

    Verified once. The same login signs in to Tend at the reception desk, Edge on the F&O book, and Tax at filing time — not seven separate signups.

  2. 02

    Consensual family graph

    Add a parent, child, or guardian; they confirm. Shield reads the same graph per-relation, so a health record is shared by consent, revocable any time.

  3. 03

    One consent ledger

    Every cross-product data access is logged against one ledger. You can see who looked at what, when, and under which grant.

  4. 04

    Notification mesh, WhatsApp-native

    One messaging spine reaches the person where they already are. A Tend appointment, an Edge fill, a Pact reminder — same mesh, same number.

8 products · the honest ledger

8 products,
in honest order.

Each entry carries its true state — shipping, live, or alpha — loudest first, quietest last. Same substrate underneath all of them. We don’t inflate the ladder.
