What Atmospheric G2 does

Atmospheric G2 (AG2) is a SaaS weather intelligence and decision-support provider focused on energy trading, energy & utilities, and weather-sensitive commercial and financial organizations. The company delivers high-resolution global forecasts, historical weather datasets, and derived analytics—wind and solar generation forecasts, degree-day demand proxies, natural gas usage forecasts in Bcf, and load forecasts for US power pools—consumed by energy traders, utilities, renewable asset operators, commodity funds, insurance/reinsurance underwriters, and corporate energy managers. The product portfolio centers on the AG2 Trader graphical platform, supported by AG2 Data REST APIs, a Snowflake marketplace data share, and three proprietary add-on modules: Probabilistic Forecast & FRisk (100-member ensemble distillation into a 0-100 uncertainty index), ForecastEdge (AI-powered prediction of ECMWF ensemble mean shifts ahead of model runs), and WeatherMaker (a custom forecast builder letting traders blend and re-weight models). Underlying data includes a 4 km global forecast grid, historical station data back to 1950, gridded reanalysis back to 1979, and the licensed GRAF high-resolution model from The Weather Company (IBM).

The business runs on tiered recurring subscriptions (Basic, Standard, Gold, Platinum) for the AG2 Trader platform, separate subscription pricing for AG2 Data API access, Snowflake data-share arrangements, and incremental license fees for ForecastEdge and WeatherMaker. Go-to-market blends enterprise field sales (dedicated account executives for North America East/West and Europe), product-led and API-first distribution (self-serve docs, Snowflake marketplace), and content-driven demand generation through a meteorologist-authored blog and active social channels. Reported commercial proof points include 3,500+ active users across 20 countries, an NPS of 81, customer-reported 1–5% improvements in trade profit, 50% reduction in reporting/modeling time, and 80% reduction in time interpreting weather data. Customer segmentation is approximately 46% Energy & Utilities, 43% Commercial & Weather-Sensitive, and 9% Finance, Insurance & Risk Management, with named enterprise logos including Swiss Re, ENGIE, Yes Energy, Gen-i, Blackout Power Trading, and Powwr. The company traces its operating history to the original WSI Trader product launched in April 2000 and was rebranded to Atmospheric G2 in 2021; it remains privately held with no disclosed external funding.

Direct peers

• StormGeo: StormGeo (now d/b/a StormGeo, owned by Arras Group) provides weather intelligence and decision-support for energy, shipping, and offshore markets with similar trader-floor use cases. Directly comparable to AG2 in serving energy traders with probabilistic forecasts and operational decision tools.
• Jupiter Intelligence: Jupiter Intelligence provides climate and weather risk analytics for financial, insurance, and infrastructure customers. Comparable to AG2's risk-management use case for insurance/reinsurance (Swiss Re is a shared customer type) and probabilistic analytics for asset-level risk decisions.
• Meteomatics: Meteomatics offers a weather data API and analytics platform for enterprise customers including energy, aviation, and insurance. Comparable to AG2's AG2 Data API and probabilistic product, with similar self-serve and enterprise motions in Europe and globally.
• Planalytics: Planalytics provides weather-driven demand analytics for energy, retail, and CPG customers. Comparable to AG2 in translating weather into energy demand/load forecasts and serving weather-sensitive commercial buyers with managed analytics.
• WeatherBell Analytics: WeatherBell Analytics delivers high-resolution weather forecasts, model data, and analytics to energy traders, agriculture, and commodities customers. Comparable to AG2 in serving trading desks with premium forecast data and expert meteorologist support.

Broad incumbents

• DTN: DTN is a large, established provider of weather, climate, and agricultural intelligence serving energy, agriculture, and aviation customers with a broader portfolio than AG2. Overlaps with AG2 in energy trading and renewable forecasting while also covering agriculture and commodities more broadly.
• The Weather Company (an IBM Business): The Weather Company / IBM Environmental Intelligence Suite offers global weather data, forecasts, and analytics across energy, media, and enterprise. AG2 is both a partner (for GRAF) and a competitor in the energy trader segment; comparable as a broad incumbent with overlapping trader-floor offerings.

Emerging players

• Tomorrow.io: Tomorrow.io is a venture-backed weather intelligence SaaS platform offering APIs, dashboards, and forecasts across multiple verticals including energy and logistics. Comparable to AG2's API-first and product-led motion, though with a broader vertical reach and significantly more outside capital.

Others

• Spire Weather (Spire Global): Spire Global's weather division provides satellite-based radio occultation weather observations and forecasts for enterprise and government. Adjacent to AG2 as an upstream data provider/complementary source rather than a direct trader-floor competitor.
• Vaisala: Vaisala is a global leader in weather observation instruments and measurement systems for meteorology, aviation, and energy. Adjacent to AG2 as an observation hardware/infrastructure provider rather than a competing SaaS analytics platform.
