Building the ground-truth weather layer.
WeatherXM builds weather hardware, observation networks and software that turn local measurements into usable data, forecasts and applications. We design for the whole path from sensor to decision: reliable instruments, resilient connectivity, clear provenance and open interfaces.
Why we build it
Better weather decisions start with better observations.
Weather data for every corner of the world.
Our mission is to collect high quality, hyperlocal weather data for every corner of the world and make them universally accessible and useful.
Open systems create more possibilities.
We believe in making the world a better place. We value public goods, open source software and open data that allow permissionless creativity and innovation.
A global, community-powered weather network.
We see a world where Web3, IoT and meteorology are combined to build a global, decentralised, community-powered network of millions of small, inexpensive weather stations.
We believe that this model will unlock great value, open up new opportunities and have a direct positive impact on the lives of millions of people around the world and our planet.
Lineage & R&D
A decade of building weather hardware.
Our environmental and industrial IoT work began in 2015. WeatherXM launched in 2022 to make connected weather stations easier to deploy at scale. Each generation has carried that field experience forward — from early gateways and LoRaWAN stations to cellular, local-first and open hardware.
First WeatherXM generation, combining cryptographic data proofs and IPFS-backed storage directly in the station workflow.
Among the early mass-produced weather products built around Semtech's LR1110, combining an all-in-one station with LoRaWAN connectivity.
Second generation added GPS, LoRa and additional observation signatures. Its ESP32-S3 gateway expanded cryptographic capabilities and local processing.
Built for remote deployments worldwide, with solar power on the gateway, cellular backhaul and support for extra sensors including water level, water quality and soil moisture.
Refined the LoRaWAN design with improved sensors and redesigned plastics for greater durability in long-term outdoor deployments.
Brings together the strongest parts of D1 and H2 with tri-protocol connectivity, native mesh operation and an open firmware and integration path.
What we build
From measurement to decision.
Use the hardware, network, data or application layer independently, or combine them when you need the whole path from a field observation to an operational decision.
Measure the atmosphere.
Connected instruments designed for real-world deployment.
Coordinate observations.
A global mechanism for deploying and sustaining ground stations.
Turn measurements into intelligence.
Observation data, derived products and forecasts grounded in local reality.
Put weather to work.
Energy, infrastructure, agriculture, research and other weather-sensitive operations.
Founders
Built by people who have spent a decade shipping weather and IoT systems.
WeatherXM was co-founded by Manolis Nikiforakis, Stratos Theodorou and Nikos Tsiligaridis, combining product, embedded systems, distributed software and real-world field deployment experience.
Backed by
Lightspeed Faction, Placeholder VC, Protocol Labs, Consensys Mesh, Borderless Capital and SOSV.
Who does what
