सायुज्य · About Sayuk

Deep union. Inseparable connection.

Sayuk comes from the Sanskrit root sayujya (सायुज्य) — a Vedantic word for the state of inseparable union, the bond between two things that are no longer separate. We chose it because that is what we build: a software layer where one person's identity, places, family and choices stay together across every product they use.

01 / Why the name matters

Most platforms collect you.
We connect you.

Every Indian uses a dozen apps daily — clinic, bank, market, filing, savings. Each one keeps its own login, its own profile, its own opinion about who you are. A dozen profiles of one person, scattered, never reconciled.

Sayuk inverts that. One identity. One family graph. One address book. One consent ledger. Products don't own your data — they read from one canonical layer you control. That is the union the name points to.

Sayujya isn't possession. It's the state where two become one without either being lost — the only honest framing for what software should do with your data.

02 / What we're building

Seven products.
One account.

Two are built for the businesses that run India — software for the desk, not the deck. Five are built for the person who lives in it. Each one carries its true state.

For the businesses that run India

  • Sayuk Tend Shipping

    Clinic + GST pharmacy on one ledger. Reception, doctor and counter write to the same database. Live in a real hospital.

  • Sayuk Edge Live

    A systematic F&O stack, trading our own capital on real money since 6 May 2026.

For the person who lives in it

  • Sayuk Tax Live

    Free ITR filing — a Zerodha .xlsx becomes classified capital gains and a valid ITR-1, ITR-2 or ITR-3 XML.

  • Sayuk Pact Alpha

    Savings circles and a trip splitter. Tracks the math, never touches the money.

  • Sayuk Shield Alpha

    Family health vault, shared per-relation by consent, with a DPDP audit trail.

  • Sayuk Trove Alpha

    Neighbourhood marketplace — depreciation pricing, masked identity, UPI escrow.

Underneath all seven
  • One identity
  • Family graph with consent
  • Address as a primitive
  • One consent ledger
  • WhatsApp-native notification mesh

03 / The flagship, concretely

Sayuk Tend runs a real hospital pharmacy.

Tend runs a real children's hospital today. The pharmacy is not a stub — it is a full counter. A walk-in sale starts from a name and a phone number, searches the shared catalog, builds a cart, and prints a GST invoice with the tax extracted from MRP.

Every tenant searches the same 2,46,000-medicine catalog and adopts an item the moment it is stocked. Suppliers, purchase orders, goods-receipt verification, and batch / expiry FIFO keep the shelf honest, with near-expiry alerts ahead of loss.

  • Walk-in POS — counter sale, no prescription required
  • 2,46,000-medicine FTS5 shared catalog, adopt-on-stock
  • Suppliers → PO → GRN, batch / expiry FIFO + near-expiry alerts
  • GST invoices, MRP-inclusive tax extracted to CGST / SGST
  • Per-Indian-FY invoice numbers, monthly GSTR-1 summary
  • Distributor CSV import, offline-tolerant SQLite-per-tenant

04 / How we work

Six rules we don't break.

  1. 01

    Every product compounds on a shared substrate.

    One identity, one family graph, one consent layer. We ship in parallel because each product makes the substrate richer, and a richer substrate makes the next product faster to build.

  2. 02

    WhatsApp before app.

    Until India shifts off WhatsApp, the product reaches people there. Reminders, confirmations and invoices arrive on the number they already use.

  3. 03

    Offline-tolerant over a perfect SLA.

    Flickery rural Wi-Fi is the real operating condition. Tend runs on SQLite-per-tenant so the counter keeps working when the line drops.

  4. 04

    English-friendly, not English-required.

    Indic name fields handled properly — no forced first / last splits. More Indian languages on the roadmap.

  5. 05

    Honest about state.

    Shipping, live, or alpha — every product wears its real state, here and on the home page. A visitor always knows what is real today and what is still early.

  6. 06

    Built for the desk. Not the deck.

    Every product earns its place through real use, not investor narrative. No procurement-decided features. No round to raise before the work is real.

We're not optimising for scale. We're optimising for the day a small-town doctor opens our app and it does what she needs without being asked twice.
