For most Indian farmers, the biggest decisions of the season are still guesses. When to water, when to spray, when to hold back on fertiliser — the answers come from experience, from the sky, and from what the neighbours are doing. A startup incubated at IIT Palakkad is replacing the guesswork with measurements. Revin Krishi puts a small solar-powered weather station in the field, reads the soil and the sky every ten minutes, and tells the farmer exactly what the crop needs that day — and in a recent deployment at a state seed farm in Palakkad, the company says paddy yields rose 33% while pesticide spending fell 64%.

One device, five acres, twenty measurements
The centrepiece is Revin Sight, an intelligent in-field monitoring device that combines weather, plant and soil data with advanced analytics. A solar-powered mast carries wind and rain sensors above the crop, while probes in the soil track what is happening below the surface. The device measures 20 parameters — soil pH, moisture, humidity, temperature, wind speed and more — and one unit covers up to five acres, sending fresh readings every ten minutes. Instead of a generic district advisory, the farmer gets guidance tuned to their own field, their own crop variety and their own micro-climate: when to water, when to fertilise, and when a pest or disease risk is building.
Advice in the farmer’s own language
The data flows into Revin Log, the company’s farm management platform, which adds climate-smart advisories, AI-powered quality analysis and pest and disease detection, along with traceability for buyers who want to know how a crop was grown. The team’s Livo app, launched in March 2026, puts the same intelligence on the farmer’s phone, with stage-by-stage suggestions through the season and a voice assistant that answers questions in the farmer’s regional language. Above it all flies Revin Skypulse, the company’s drone service, which maps fields in high resolution to assess soil, fertility, crop health and yield — the aerial view that turns a single sensor’s readings into a picture of the whole farm.

The numbers from real fields
The results are coming from working farms, not test plots. At Alathur State Seed Farm in Palakkad, the company says its system helped increase paddy yield by 33%, cut pesticide expenditure by 64% and lower production costs per kilogram by up to 31%, delivering an additional economic benefit of Rs 8.03 per kilogram. Turmeric farmers in Tamil Nadu and Kerala, where the company’s devices are also deployed, have seen yields rise 18% with improved curcumin content, and the company says farmers can recover the device’s cost from a single season’s harvest. The company says 750 farmers across South India now use its technology, and its devices are deployed in farmers’ fields as well as research and seed-producing organisations, including the Indian Council of Agricultural Research and government farms. Across its deployments so far, the company reports grower incomes up 18%, farm produce up 22%, input costs down 28% and water use down 33%. In October 2026, Elappully panchayat in Palakkad partnered with the startup for a 250-acre pilot, installing farm-monitoring devices, mapping fields with drones and advising farmers on precise water use through the alternate wetting and drying method, with a target of cutting paddy production costs by at least 40%.
Bootstrapped from a campus lab
Revin Krishi began as research in 2018 and was formally established in 2023 by Sreehari Vijayakumar and Dr Sreenath Vijayakumar, an associate professor at IIT Palakkad, building the technology as a bootstrapped venture and validating it under real farming conditions. The team has also run more than 580 AgriTech training initiatives, teaching growers to read their own fields through data. The immediate focus now is scale: taking the proven model across India’s major agricultural regions, starting with paddy cultivation, and bringing farm intelligence to thousands more farmers. For a country where a single season can decide a family’s year, a small sensor on a pole is turning out to be one of the most practical pieces of technology in Indian agriculture.
