About · DOC-ABT-2026 / REV C

We build for fields,
not labs.

Started in 2024 in Coimbatore. A small team of engineers building automation for Indian farms — pumps, tanks, valves, and the everyday machinery that keeps a season going.

DOC · ABT-2026 / REV C

HorizonGrid was started in 2024 in a borewell shed outside Pollachi, where a 7.5 HP pump had burned out for the third monsoon in a row — not because the motor was weak, but because the village grid that fed it had given up first.

We build automation for farms. Not for offices, not for labs — for the panel inside your pump-house, the float-switch on your overhead tank, the starter on your borewell. The everyday machinery that decides whether this season's irrigation goes through, or doesn't.

Every HorizonGrid device is built to work the way a farmer actually uses it: a press of a button on the device itself, or one tap on your phone. No internet at the pump? No problem — the device makes its own decisions. Voltage too low, motor running dry, tank already full — it stops on its own, and tells you what happened the next time you check.

We test in 45 °C summer heat, with hard water and the kind of 3-phase supply you actually get in a village. We pot the boards in resin by hand on the first hundred units of every revision. If a device fails, an engineer is on a motorcycle to your farm within 48 hours.

Our promise is simple. A motor turns on, or it doesn't. A tank fills, or it floods. We are in the business of making sure the thing you expected to happen, actually happens — quietly, on time, season after season.

§ 02 · Timeline

Two years.
One field at a time.

2024 · Q1
A burnt motor in Pollachi
HorizonGrid started after the third borewell motor failure of the season — to build a starter that protects itself before the farmer even gets the SMS.
First sketch · Fable H1 prototype
2024 · Q3
Fable H1 ships
First Fable units installed across nearby farms in Coimbatore and Tiruppur. Dry-run protection, voltage protection, hand-potted, IP65 housing.
First field installs · Tamil Nadu
2025 · Q2
Fable H2 + wireless control
Three-phase, 10 HP-rated, with long-range wireless — finally letting the farmer start the pump from home, without internet.
RF link · up to 2.5 km · no SIM
2025 · Q4
HG IoT Hub launches
One gateway, one Wi-Fi connection — links every motor and valve on the farm to the farmer's phone. The spine of a multi-device setup.
Buttons + OLED · single Wi-Fi link

25 devices online
Across early farms in Tamil Nadu. New Water Level Controller and HG Weather Station join the catalogue.
25 devices · 99.9% uptime · 3-year warranty
§ 03 · How we work

Four operating rules.

RULE · 01

Edge first, cloud second.

Every safety loop closes on-device in <50 ms. The cloud is for hindsight, not survival. We will never ship a device that needs internet to protect a motor.

RULE · 02

Test in May, not in June.

Every Fable revision is tested in 45 °C ambient with hard water and dirty 3-phase. If it survives Erode in May, it will survive anywhere.

RULE · 03

Your data stays yours.

The farmer owns the data. View it on the device's OLED, on the phone app, or export it as a simple spreadsheet. We will never lock it behind our cloud.

RULE · 04

Service is part of the product.

Two-year on-site warranty. If a device fails, an engineer is on a motorcycle within 48 hours. No call-centre tickets.

to your fields.

Talk to a field engineer about the right automation for your farm or factory floor. We design the system around your panel — not the other way around.
