Top 10 IoT Companies in India (2026): Platforms & Clouds

Updated October 2026. This list replaces our 2020 version, which had aged badly: two of its picks were US consumer gadgets and one was a smart-home hub Google switched off years ago.

Most people meet the Internet of Things through a video doorbell. The bigger story in India sits out of sight: electricity meters that report every 15 minutes, vibration sensors bolted to cement-plant motors, soil probes in Nashik vineyards. The IoT companies in India doing this work are a mix of telecom giants, listed manufacturers and venture-backed startups, and nearly all of them run their own cloud platform where device data lands, gets stored and is turned into alerts.

Ken Research values the Indian IoT market at about USD 50.1 billion in 2025 and expects it to reach USD 109 billion by 2031, a 13.8% annual growth rate. Smart metering, connected factories and fleet tracking drive most of that spend.

How we picked these 10

Every company here is Indian (founded or headquartered in India), was active in 2025–26, and owns the platform its devices report to. We left out IT-services firms that build IoT projects for clients, because their platforms usually belong to someone else. We also aimed for spread: connectivity, utilities, factories, buildings, farms and field equipment.

The top IoT companies in India

1. Reliance Jio (JioThings)

Jio built a nationwide NB-IoT network, a low-power cellular standard designed for sensors that send small packets of data for years on one battery. Its IoT arm, JioThings, sells the whole package: hardware, connectivity, platform and field service. Its most visible work is in smart gas and water metering for city gas distributors and municipal bodies. If you are a utility that wants one vendor to answer the phone, this is the pitch.

2. Bharti Airtel (Airtel IoT)

Airtel Business became the first Indian provider to cross 20 million connected IoT devices, in July 2023. Its Airtel IoT platform manages SIMs and eSIMs across 5G, 4G, NB-IoT, 2G and satellite links, and sells packaged solutions for vehicle telematics, asset tracking, industrial monitoring and smart metering. The company has called IoT one of its fastest-growing enterprise lines. Fleet operators and two-wheeler makers are typical customers.

3. Tata Communications (MOVE)

Tata Communications solves a problem the first two do not: devices that cross borders. Its MOVE platform provisions and monitors SIMs and eSIMs across many mobile networks worldwide, which matters to carmakers and logistics firms shipping connected products abroad. In September 2025 it announced a collaboration with Cisco on eSIM and IoT connectivity management.

4. Genus Power Infrastructures

India’s smart-meter rollout under the Revamped Distribution Sector Scheme is one of the largest IoT deployments anywhere, and Jaipur-based Genus is among its biggest suppliers. As of 30 June 2025, the listed company reported an order book of about ₹29,321 crore. Its metering-service orders cover roughly 3.5 crore smart meters, of which around 45 lakh had been installed. Each of those meters is an IoT endpoint reporting consumption to a utility’s head-end system.

5. Altizon Systems (Datonis)

Founded in Pune in 2013, Altizon makes Datonis, an industrial IoT platform that pulls data from PLCs, SCADA systems and shop-floor sensors into one layer. More than 100 enterprises use it, with data arriving daily from over 30 countries. Datonis appeared in Gartner’s Magic Quadrant for Industrial IoT Platforms in 2018. More recent additions include FactoryGPT, a chat-style assistant for plant teams, and a production-intelligence offering for steel, cement, chemicals and power plants.

6. Infinite Uptime (PlantOS)

Infinite Uptime puts vibration and temperature sensors on motors, pumps and gearboxes and predicts failures before they stop a line. Founded in 2015, it serves more than 300 customers across 800-plus plants in 26 countries, mostly in cement, steel and oil. In 2025 it raised USD 35 million in a Series C led by Avataar Ventures, taking total funding to about USD 65 million. The money is going into PlantOS, which combines equipment data with process data to cover reliability and energy use together.

7. Detect Technologies (T-Pulse)

Chennai’s Detect Technologies combines cameras, sensors and AI to watch for safety and integrity risks at refineries, plants and construction sites. Its T-Pulse platform flags things like missing protective gear or unsafe entry into restricted zones as they happen. Shell signed a global agreement to deploy T-Pulse across its operations, and Detect raised a USD 28 million Series B led by Prosus Ventures, with Shell Ventures among the investors.

8. Zenatix (by Schneider Electric)

Gurugram-based Zenatix, founded in 2014, automates air-conditioning, lighting and energy monitoring in commercial buildings such as retail chains, bank branches and offices. Its ZenConnect platform uses a wireless mesh, so sites can be retrofitted without rewiring, and it runs in more than 3,000 buildings across 200-plus Indian cities. Schneider Electric acquired the company, which now operates as Zenatix by Schneider Electric.

9. Fasal

Fasal brings IoT to horticulture. Its Fasal Kranti field unit carries more than 12 sensors for rainfall, wind, leaf wetness, soil moisture and temperature, and its app turns the readings into irrigation and spray advice in regional languages. NITI Aayog’s frontier-tech programme has written it up as a case study in water savings. In April 2025 the Bengaluru company launched FasalOne, a farm IoT platform meant to work across crops and farm sizes.

10. Datoms

Bhubaneswar-based Datoms connects heavy equipment such as generators, compressors and construction machines to what it calls a connected operations cloud. Equipment makers use it to offer their machines as “smart” products, and fleet owners use it to plan maintenance. It works with more than 100 customers, including Mahindra & Mahindra and Tata Motors. Datoms raised a ₹25 crore Series A led by BIG Global Investments, with YourNest and IvyCap Ventures also investing.

Also worth knowing: consumer IoT

For the home, the strongest Indian name is Qubo, from Hero Electronix. It sells security cameras, video doorbells, smart locks, dashcams and GPS trackers. Qubo crossed ₹275 crore in revenue in FY25, has shipped over a million devices, and owns its full software stack, so the cloud your camera footage goes to is its own. Its cameras hold the government’s ER security clearance.

Which kind of IoT company do you need?

• You need SIMs and connectivity for thousands of devices: Jio, Airtel, or Tata Communications if devices leave India.
• You run a factory: Altizon for plant-wide data, Infinite Uptime for machine health, Detect for safety.
• You manage many small buildings: Zenatix.
• You farm or advise farmers: Fasal.
• You make or rent out heavy equipment: Datoms.

One practical question to ask any vendor is where your data is stored. Industrial and utility data increasingly has to stay in Indian data centres, and that demand is part of why capacity is growing so quickly. Our guide to India’s data centre boom explains what is driving it.

Frequently asked questions

Which is the biggest IoT company in India?

By connected devices, the telecom operators lead: Airtel passed 20 million IoT connections in 2023, and Jio runs a national NB-IoT network. By order value in a single IoT category, smart-meter makers such as Genus Power are among the largest, with orders covering crores of meters.

Which Indian IoT startups are growing fastest?

Industrial IoT is attracting the largest rounds. Infinite Uptime’s USD 35 million Series C in 2025 was one of the biggest, and Datoms, Detect Technologies and Fasal have all raised to expand beyond their home markets.

Do Indian IoT companies store data in the cloud?

Yes. Each company on this list runs its own platform: Datonis, PlantOS, T-Pulse, ZenConnect, FasalOne and so on. Device readings are sent there, stored and analysed. Many of these platforms are hosted on public clouds, so ask a vendor which region holds your data if residency matters to you.

Is IoT a good career field in India?

Demand is strongest for embedded engineers, people who can connect industrial machines (PLCs, Modbus, OPC-UA), and data engineers who build on time-series data. The smart-meter rollout alone needs installation and support teams in every state.
