The most expensive weather forecast in the world is the one you ignore. For Shimon Elkabetz, the co-founder and CEO of Tomorrow.io, that lesson came with the shudder of an F-16’s airframe. After 11 years as an Israeli Air Force pilot, where he faced multiple near-death experiences related to weather, he started a company in 2016 to sell something more useful than a percentage chance of rain: an operational command [Activate Capital, Unknown].
Today, that company is a Boston-based unicorn with over 250 enterprise and government customers, a fresh $210 million Series F, and a valuation north of $1 billion [PERPLEXITY SONAR PRO BRIEF, February 2026] [7]. Its bet is that the path to dominating a multi-billion dollar weather intelligence market runs through low Earth orbit. Tomorrow.io is not just aggregating data; it’s building its own AI-native satellite constellation, called DeepSky, to collect it. The goal is to move from telling Uber that it will rain to telling Uber precisely which city blocks to surge-price its drivers away from, and when.
From ClimaCell to constellation
The company began as ClimaCell, with a novel wedge: using signals from wireless networks and IoT devices to infer hyperlocal weather conditions, a clever workaround for sparse ground sensors. It sold that data via API and dashboard to a blue-chip roster including Uber, Delta, Ford, and National Grid. The pivot to Tomorrow.io in 2021 signaled a broader ambition, from data provider to resilience platform. The real strategic leap, however, came with hardware.
In 2023, the company launched its first two satellites equipped with precipitation radar, claiming the title of the first commercial weather radar in space [PERPLEXITY SONAR PRO BRIEF, 2023] [7]. This was the opening salvo for DeepSky. The planned full constellation, targeted for completion within 18-24 months of June 2023, aims to field over 20 satellites with a diverse sensor suite: microwave sounders, optical cameras, and more. The stated objective is an hourly global weather revisit rate, observing the atmosphere anywhere on Earth every 60 minutes.
The unit economics of atmospheric certainty
The rationale for spending hundreds of millions on satellites is a classic vertical integration play. Owning the sensor layer means controlling the data’s granularity, latency, and cost structure. For a logistics giant like Ford or a utility like National Grid, the value isn’t in a slightly more accurate temperature readout. It’s in the avoided cost of a delayed shipment, a downed power line, or a canceled flight.
Tomorrow.io packages this into what it calls a climate-adaptation platform. The workflow typically starts with its core data and forecasting engine. On top of that sits Gale, a generative AI product launched in 2023 that the company bills as the first dedicated AI for weather and climate. Gale is designed to act as an intelligent agent, translating complex forecasts into plain-English recommendations for specific business roles,telling a warehouse manager the optimal time to schedule loading docks before a storm hits, for instance.
The company’s funding history shows investors betting heavily on this full-stack approach.
Series C (Jul 2020) | 23 | M USD
Series D (Mar 2021) | 77 | M USD

Series F (Feb 2026) | 175 | M USD
Series F Ext (May 2026) | 35 | M USD
With total disclosed funding now at approximately $535 million, the capital is earmarked for scaling the satellite network and the enterprise sales engine needed to monetize it [PERPLEXITY SONAR PRO BRIEF, May 2026].
The team commanding the mission
The founding trio has steered the company from its cellular-data origins to its space-centric future. Elkabetz, the former pilot, provides the strategic vision and operational tempo. Rei Goffer, as Chief Strategy Officer, and Itai Zlotnik, as Chief Commercial Officer, round out the leadership [19]. They’ve built a team that now exceeds 220 employees, with a significant R&D presence in Israel [PERPLEXITY SONAR PRO BRIEF, February 2026].
Key hires have bolstered their execution capabilities. Moti Karmona serves as Chief Product & Engineering Officer and General Manager for Israel, overseeing the technical build of both software and satellites. Kelly Peters, as VP of Marketing, brings over a decade of demand-generation experience from brands like CNBC and NBCUniversal.
Where the forecast gets cloudy
No bet this capital-intensive is without profound risk. The challenges for Tomorrow.io are not trivial, and they break down into three main categories.
- Capital intensity. The DeepSky constellation is a breathtakingly expensive undertaking. The $535 million war chest must fund satellite design, launch, insurance, and ground operations, all while financing a global enterprise sales team. The company will need to demonstrate that its SaaS revenue can quickly outpace its space-based capex burn.
- Technical execution. Building and operating a reliable satellite constellation is famously difficult. Any significant delays or technical failures in the DeepSky rollout would undermine the core data advantage the company is selling.
- Market education and competition. Tomorrow.io must convince CFOs that its integrated platform is worth a premium over cheaper, forecast-only APIs. While no direct competitor is named in sources, the company acknowledges its business model is "more comprehensive" [23]. It competes with the inertia of existing workflows and the entrenched relationships of legacy weather data providers.
The company’s answer to these risks is its customer list and its integrated product story. By selling the outcome,operational resilience,rather than the data feed, it aims to command higher contract values and become a mission-critical system.
The next atmospheric layer
The coming 12 to 24 months are the proving ground. The milestone is clear: the successful deployment of the full DeepSky constellation. Each new satellite that reaches orbit and returns data strengthens the proprietary moat. Commercial traction will be measured in enterprise contract expansions and new logos in regulated, weather-sensitive industries like energy, aviation, and insurance.
A back-of-the-envelope calculation illustrates the stakes. If a major airline avoids just 50 weather-related flight cancellations a year, each costing an estimated $50,000 in direct and downstream losses, that’s $2.5 million in annual savings. For a platform serving hundreds of such enterprises, the total value preserved,or captured,runs into the billions. That’s the math Tomorrow.io is selling.
Ultimately, the company isn’t trying to beat your phone’s weather app. It has to beat the internal spreadsheet where a logistics manager guesses at the storm’s impact, and the generic government forecast that doesn’t know the location of his most vulnerable warehouse. It’s a bet on precision replacing probability, and on satellites becoming the most valuable desk in the operations center.
