Tomorrow.io
Weather intelligence platform for operations — hyperlocal forecasts, air quality and history with location-aware rules, alerts and routing.
Rebranded
Founded 2016 as ClimaCell; rebranded to Tomorrow.io in 2021 alongside its Series C.
About
Tomorrow.io is a Boston weather-intelligence platform aimed at businesses whose operations live or die by the sky: airlines, automakers, utilities, sports leagues. It was founded in 2016 by Shimon Elkabetz, Rei Goffer and Itai Zlotnik — three former Israeli military men — as ClimaCell, and rebranded to Tomorrow.io in 2021 alongside a $77M Series C. The pitch is not just forecasts but decision logic: set thresholds on locations, polygons and routes, get alerts when weather crosses them, and push recommendations to the right teams.
The company is building its own observation layer, a constellation of radar satellites (the first ones flying by 2025), feeding a 'NextGen' premium data product. Customers named in its materials include Uber, Ford, Delta, JetBlue and the NFL, and total funding sits around $470M after a 2025 raise. Developers get a free API tier at 500 calls per day; anything beyond that is custom enterprise pricing, which independent comparisons peg as starting in the hundreds of dollars per month.
What it can do
- Realtime, forecast and historical (to 2000) weather API
- 30+ weather and air-quality parameters
- Point, polygon and route queries
- Location-aware rules and threshold alerting
- Interactive maps with color-coded layers
- Postman collection and testing tools
Setup
Sign up at tomorrow.io, generate an API key from the developer dashboard, and call the realtime/forecast/history endpoints — or configure location rules and alerting in the web console.
Prerequisites
Account signup; paid plan for production-scale call volumes.
Use cases
Works with
Trust score — 7/10
Scored 7/10 (TIER metrics, metrics-v1). Evidence: founding team, 2016 origin, 2021 ClimaCell→Tomorrow.io rebrand and ~$470M funding verified across three independent reports (WebProNews, TechStartups, KrASIA); customer list (Uber, Ford, Delta, JetBlue, NFL) cited by multiple outlets. Strengths: genuine enterprise traction, own satellite observation program differentiates its data supply, free developer tier. Docked for: (1) accuracy claims vs incumbents are provider-stated without published independent benchmarks; (2) pricing above the free 500 calls/day is opaque and custom; (3) the 2021 SPAC listing fell apart, so it remains private with limited financial disclosure. License: proprietary SaaS; free to 500 API calls/day, paid plans custom.
