About RetailDA™

The operating system retail never got.

A TolsTek Group company. RetailDA™ builds WeBFooT® Ultra Z — a single operating system for multi-site retail, hospitality and industrial operations. Offline-resilient at the edge, consolidated at the centre, and grounded in the operator's own data.

Mission

  • Put the whole stack in the hands of the industries that run on it — delivered where operations actually live.
  • The offline-first engine, the tamper-evident ledger, the sovereign AI — one system, not a patchwork.
  • On infrastructure they own, never rented — so every store, kitchen, warehouse, factory and property reaches that world on its own terms.

Vision

  • One record at every scale — a 3-store independent retailer and a multi-brand, multi-outlet, multi-franchise global chain run the same record.
  • One ledger, every dimension — sites, warehouses, currencies, entities and countries, reconciling every mix of inventory.
  • AI that illuminates and liberates — answering only from the operator's own data, illuminating the truth inside them and liberating human hours.

The road so far

Built in the field, not in a pitch deck.

2017JDVPL incorporated

Jiggle De Venture Private Limited registered in Kolkata — retail and distribution software becomes the trade.

WeBFooT®Field software ships

WeBFooT® deployments across retail, pharmacy and hospitality — including air-gapped defence & PSU canteens that still run untouched.

Ultra ZThe flagship platform

Offline-first engine proven at 97 concurrent terminals — the same binaries from a Kashmir laptop to a power-edge rack.

ShivOlive™The industrial layer

Zero-chemical water-treatment plants on custom ESP32 hardware — SCADA telemetry joins the same record that runs the storefront.

RetailDA™The umbrella brand

55 apps, grounded RAG, sovereign hosting — one operating system for the whole floor, under one brand.

What we believe

Software should serve the store, not the other way round.

Offline is not a feature flag

Connectivity is weather. Checkouts, ledgers and tax logic execute on the terminal and reconcile upstream — the store does not pause for a leased line.

Your data stays yours

Stock, customers and ledgers live on your hardware or your chosen cloud. RAG answers come from your catalogue, grounded — never trained into someone else's model.

Priced per site, not per seat

A register that bills you again every time you hire a cashier is rent-seeking. One site, one price, unlimited staff.

The code we run on

Ancient discipline, modern engineering.

Indian spiritual wisdom expressed as system architecture — a record that cannot lie, machines that do machine work, and people who get their time back.

SATYA · TRUTHA record that cannot lie

Brutally honest by design — every transaction, torque reading and flight hour is signed, sequenced and auditable. Transparency is not a policy here; it is the schema.

DHARMA · RIGHT DUTYMachines do machine work

Patrols, counts, dosing, flights — executed exactly as specified, without fatigue or drift. Duty performed flawlessly is what machines are for.

MOKSHA · LIBERATIONHumans get their time back

Systems that run themselves return the hours — for judgement, creation, family and the work only people can do. Autonomy in service of human life.
