Building a complete operating system for Indian MSMEs

Hey Product Hunt,

I am Jai.

I want to tell you about a problem

that 63 million people have right now

and nobody is solving correctly.

——

Indian small business owners run their

entire business on WhatsApp.

Supplier orders — WhatsApp.

Customer payments — WhatsApp.

Staff coordination — WhatsApp.

Family updates — WhatsApp.

Everything important in their life

lives in one app.

But their actual business back office?

Scattered everywhere.

Bookkeeping in a notebook.

Invoices on scraps of paper.

GST filing — panic every 20th of the month.

CA available once a year.

Government portals — English, complex,

terrifying.

156 laws to follow.

Zero guidance in their language.

——

Here is what I realised.

The problem is not that these tools

do not exist.

Tally exists. ClearTax exists.

Khatabook exists. Zoho exists.

The problem is that every single one

of them requires the business owner

to leave WhatsApp, learn new software,

read English, and trust a system

they do not understand.

Nobody is meeting them where they are.

——

So we are building karSathi.

The complete operating system for

Indian small business.

Delivered entirely through WhatsApp.

The owner never leaves their comfort zone.

They just talk.

"Aaj 25k ka dhanda hua"

→ Bookkeeping done automatically.

"GST kitna pending hai?"

→ Exact liability calculated instantly.

"Invoice bana do — Ramesh ko

15,000 ka maal diya"

→ PDF invoice generated on WhatsApp.

"Is month profit kam kyu hua?"

→ Analysis based on their own data.

"Aaj kaunsi deadlines hain?"

→ Personalised compliance calendar.

No app. No English. No dashboard.

No learning curve.

Just WhatsApp.

——

The memory layer is what makes

this a real business.

After 12 months of conversations —

karSathi remembers everything.

It remembers that last March sales

dropped because inventory arrived late.

It reminds the owner 2 weeks before

the same season this year —

"Bhai pichle saal is time inventory

late aayi thi. Is baar pehle se

order kar liya?"

That is not a reminder tool.

That is a business advisor.

One that never sleeps. Never forgets.

Never charges Rs 30,000/month.

——

The CA side makes this a platform.

India has 350,000 Chartered Accountants.

Each manages 50-200 MSME clients.

karSathi gives every CA a dashboard

that shows exactly what their clients

are asking on WhatsApp — in real time.

Before a client call the CA already

knows what the client is confused about.

karSathi handles the 90% of questions

that should never need a CA.

CA focuses on the 10% that does.

One CA recommends karSathi to their

50 clients. Those 50 clients attract

more CAs. More CAs bring more clients.

Classic two-sided flywheel.

——

We are entering the market through

compliance.

Not because compliance is the vision.

Because compliance is the sharpest

pain every MSME feels every single month.

Missing a GST deadline costs Rs 50/day.

Missing FSSAI costs Rs 5 lakh.

Missing EPF costs 25% damages.

Every MSME owner is afraid of this.

That fear is the door.

Once inside — bookkeeping, invoicing,

insights, memory, CA coordination —

all of it follows naturally.

——

This is not a chatbot.

This is not a compliance tool.

This is not a CA software.

This is the back office of Indian

small business — finally living where

the owner already lives.

On WhatsApp.

——

We launch V1 in 3.5 weeks.

Compliance first. Everything else after.

But the vision is the whole thing.

At 1% penetration on both sides —

Rs 4,400 crore ARR.

At 5% — this is a billion dollar company.

——

Three honest questions for this community:

1. Have you seen this model work

in other emerging markets?

WhatsApp as business OS?

2. What would make you trust a

WhatsApp bot with your business?

What is the trust threshold?

3. What kills this? Be brutal.

I am 19 and I need real answers.
