Sutron
1/6Sutron
The operating system for services

Six apps.
One thread.

Sutron puts encrypted chat, protected courses and a real storefront on one thread — so the work you do and the money you earn stop living in six different places that have never heard of each other.

  • End-to-end encrypted
  • UPI-first checkout
  • Free until you earn

The problem

Your business is six logins.

Not one of them knows what the others did. So you become the integration — copying, pasting, reconciling and remembering.

  • The group chat

    Students ask questions you can never find again.

  • The drive folder

    Your course is a link anyone can forward.

  • The DM inbox

    Orders arrive in between the memes.

  • The video call

    Live class today. Gone tomorrow.

  • The payment link

    Money lands somewhere the work does not.

  • The spreadsheet

    You reconcile all of it by hand, on Sunday.

Six tools. Six bills. Nothing that knows about anything else.

There is a version of this where it is one thread.

The shift

One thread. Every job.

The same identity, the same catalogue and the same ledger under all three. Sell a course to someone you are already talking to, and the conversation, the entitlement and the money are the same thread.

An unbreakable vault

Messages are sealed on your device and opened on theirs. We hold the envelope and cannot read the letter.

A live classroom

Lessons decrypt in memory as they play, track where each learner stopped, and issue a certificate that verifies.

A ledger that balances

Every sale posts a double-entry record. Fees, tax and splits are computed once and frozen against that order.

End-to-end encrypted

Legible only to whoever holds the key.

The message is right there on the server. Without the key it is noise — to an attacker, to a court order, and to us.

Did the fees go through for Priya?
Yes — settled this morning. Ledger is clean.
And nobody else can read this?
Nobody. Not even Sutron.
Five architectural guardrails

Rules the platform cannot break.

Not policies somebody has to remember. Laws the code is shaped around, so the failure is impossible rather than unlikely.

  1. 01
    One identity, resolved once

    Who you are is decided in one place.

    Every service receives the same immutable identity object — never a header, never a field the client filled in. No screen gets to invent its own idea of who owns what, so ownership cannot drift as the platform grows.

  2. 02
    Frozen decisions

    What was decided cannot be quietly rewritten.

    The moment a publication, an order, a settlement or a tax figure becomes real, it is frozen into a snapshot. Everything downstream reads the snapshot. Nobody recomputes last month's money with this month's rules.

  3. 03
    Permanent denomination

    Every rupee carries its currency.

    No amount exists anywhere without an explicit currency — not in the ledger, not in a payout, not in a report. Two currencies are never added into a single total, because that would assert a conversion nobody performed.

  4. 04
    Link opacity

    A shared link reveals nothing.

    Every share link is the same shape. No tracking parameter, no referral tag, no query string at all — because having one is itself the tell. You cannot see what a link points at, or whether it pays anyone, until you are entitled to know.

  5. 05
    Preview is publish

    What you preview is what the world sees.

    Preview and live pages run the same assembler against the same fail-closed visibility rules. There is no second code path that could show you one thing and your buyer another.

Creator OS

Everything you sell, in one place.

Chat

Spaces, not another group

Discord-class spaces for your students and your team, with end-to-end encryption on by default — a property of the architecture, not a setting somebody has to find.

  • Channels, threads, pins and roles
  • Encrypted on every device, including the backups
  • Bots that answer the question you have answered forty times

Learn

Courses that cannot be forwarded

Video and PDF lessons that decrypt in memory and never land on disk as plaintext. Your course stops being a link somebody can paste into a group of four hundred people.

  • Per-file encryption with keys released only to entitled learners
  • Screen capture blocked, progress tracked, certificates issued
  • Live sessions that become lessons when they end

Sell

A storefront, not a payment link

Your shop, your buyers, your money — with UPI-first checkout and an exact-decimal ledger behind it. You can follow every rupee from the sale to your bank account.

  • Digital products, courses and bundles in one catalogue
  • Money in paise-exact decimals — never floating point
  • Every fee, tax and split recorded against the sale that caused it

What it costs

Free to start. We earn when you earn.

No monthly fee to open a shop, publish a course or run your spaces. The platform fee lands only after a sale settles — and you can see exactly which sale paid it.
