AI VISION · HANDHELD + DRONE · PRECISION SPRAYING

Spray only where
the weeds actually are.

Pesticide is sprayed by the calendar — every 10–14 days, regardless of what's actually in the field. We mount AI vision on handheld sprayers and drones, so growers only treat the weeds and pests the model can see.

Move across the field — see what the model sees.

WHY NOW

Calendar spraying is universal — and finally fixable.

30–40%

of pesticide sprays applied globally aren't needed by detection

Calendar timing, not pest presence — the default everywhere from California to Karnataka

~$80B

global pesticide market — and ~25% of crops are still lost to pests

More chemistry hasn't solved the visibility problem

~$10B

precision-agriculture market, growing 12%/yr

But most precision tech today is built for >100-acre Western farms — not the 2-acre majority

50–60%

of pesticide active ingredients in major importing countries trace to one or two suppliers

Supply shocks compound calendar overuse — precision is also resilience

+10–40%

yield / income lift in precision-spray studies vs calendar default

Range across ICAR, CICR and Karnataka pilots. Upside is largest where farms are smallest.

~440

Indian districts with dangerous nitrate groundwater

Pesticide and fertiliser over-application has crossed into public-health territory

WHY THIS MATTERS

“He sees five weeds. He sprays the entire two-acre plot. Losing the crop is the bigger risk.”

A Karnataka cotton farmer's logic.

This is the asymmetric-risk math under every smallholder spray decision worldwide. We remove the asymmetry: when AI has already walked the field, the grower doesn't have to insure with chemistry.

TWO HANDS, ONE EYE

AI vision. Two ways to spray.

Aerial · 10+ acres

The Drone

Drone-mounted AI vision plus variable-rate spray. A single pass treats only the zones the model detects. Built for medium-to-large fields, contract-spray operators, and grower co-ops that pool equipment.

Handheld · 1–10 acres

The Wand

A smart handheld sprayer that looks like the knapsack devices smallholder growers already use. Camera in the nozzle, fires only on detection. No drone licence, low CapEx, walk-the-field workflow — the wedge product where labour is cheaper than aerial logistics.

HOW IT WORKS

Three steps. One pass.

Scan

In your hand or above the field, the camera streams imagery to our on-device vision model. No cell connection required.

Identify

Trained on weeds, pests, and crop disease in the cropping systems we operate in. Sub-meter localisation, cheap inference at the edge.

Spray

In the same pass, the sprayer fires only at detected zones. Less chemistry. Healthier soil and water. Higher yield. Lower per-acre cost.

A 4-acre Karnataka plot. The orange cells are the only zones we actually treat — the rest stays clean.

PILOT

Starting in Karnataka, India.

Karnataka horticulture (grapes, tomatoes) is our first testing ground. The wand and the drone work anywhere the same calendar-spray problem exists. We're opening the pilot to growers, co-ops, contractors, and investors who want to be part of this early. Tell us who you are below.
