What WeatherPromise does
WeatherPromise is a parametric weather-guarantee platform founded in 2022 that protects travelers from adverse weather at their destination through automatic, claims-free payouts triggered when rainfall or other weather thresholds are breached. The company is headquartered in Morristown, NJ (with a New York reference in third-party coverage) and operates a wholly owned European subsidiary, WeatherPromise (Germany) GmbH, in Berlin, which holds a German insurance intermediary license under § 34d GewO. Its core product is sold exclusively through travel partners via single-click API integration into partner booking and checkout flows, meaning consumers encounter WeatherPromise at the point of purchasing a flight, hotel, or vacation rental rather than through direct-to-consumer marketing.
The underlying platform ingests 350M+ daily data points across 2.5 million global grid points from sources including NASA, NOAA, satellites, and radar, combined with 20 years of historical weather patterns used to design tailored offers. When contracted weather conditions are met, payouts are issued automatically within two business days without claims or paperwork, and travelers monitor trip conditions and payout status through a personal dashboard while partners use a dedicated dashboard for performance transparency. Marquee distribution partners include JetBlue Vacations, Marriott, Expedia, Vrbo, HomeToGo, Invia, and ab in den Urlaub, and coverage extends across 95 countries on six continents. The Jamaica 'Great Weather Guarantee,' co-launched with JetBlue Vacations and the Jamaica Tourist Board in March 2026, exemplifies a destination-specific white-labeled product offering $500 automatically if rainfall exceeds promised thresholds.
WeatherPromise earns revenue primarily through a per-booking transaction fee charged to consumers at checkout, with revenue mechanics augmented by B2B partner distribution (B2B2C) via API integrations and reinsurance-backed capacity from Greenlight Re that allows it to scale guarantee volume without absorbing weather risk on its balance sheet. In January 2026 the company closed a $12.8M Series A led by Maveron (more than 3x oversubscribed), bringing total disclosed funding to over $22M, and it was named to the TIME100 Most Influential Companies 2026 list. The company is led by co-founders David Klemm and Daniel Price, has 11–50 employees, and remains privately held.

Revenue model
- Per-booking WeatherPromise fee (consumer-paid at checkout): Travelers add a WeatherPromise to their booking at checkout; the product is a paid guarantee (not free) with pricing defined per offer. Revenue is generated on each guarantee sold, settled through third-party payment processors such as Stripe.
- B2B partner distribution (B2B2C) via API integrations: WeatherPromise is integrated into partner platforms (OTAs, airlines, hotels, vacation rentals) so its guarantees are sold at the partner's checkout, creating a B2B2C channel; WeatherPromise handles fulfillment, payouts, and customer support.
- Reinsurance-backed capacity (Greenlight Re): Every guarantee is backed by Greenlight Re, a global reinsurance provider, allowing WeatherPromise to scale capacity and absorb weather risk on its balance sheet while selling guarantees to consumers.

WeatherPromise product offering
Product offeringCore offering
WeatherPromise sells an automatic, parametric weather guarantee that protects travelers from adverse weather (primarily rainfall) at their destination. If observed conditions at covered grid points exceed contracted thresholds, customers receive an automatic payout within two business days without filing claims or paperwork, while still being able to take their trip. The guarantee is distributed B2B2C via a partner API embedded into travel platforms (OTAs, airlines, hotels, vacation rentals) at checkout, with optional direct consumer purchase on its own storefront. Every guarantee is backed by global reinsurer Greenlight Re.
Product overview
WeatherPromise is a single, unified parametric weather-guarantee platform — not a multi-module suite of separate products — consisting of one core consumer product (the WeatherPromise Weather Guarantee) supported by an integrated B2B layer (the Partner API & Integration Platform, which exposes the guarantee to travel brands via a single-click API integration and includes the Partner Dashboard for performance and offer optimization). The Personal Customer Dashboard is a feature of the core product that lets travelers monitor real-time conditions and payout status for their trip, while the Great Weather Guarantee for Jamaica is a named, destination-specific sub-product of the core guarantee, co-launched with JetBlue Vacations and the Jamaica Tourist Board. Every WeatherPromise contract is backed by Greenlight Re, a global reinsurance provider.

WeatherPromise competitors and assessment
Company assessmentOthers
- Munich Re: One of the world's largest reinsurers with parametric insurance capabilities and weather-related reinsurance products. Relevant as a potential alternative reinsurance capacity provider to Greenlight Re and as a broader parametric insurance ecosystem participant.
- InsureMyTrip: Travel insurance comparison marketplace that aggregates and compares policies from multiple carriers. Comparable as an adjacent travel insurance distribution channel and as a comparison destination where WeatherPromise's parametric product could either be listed or displaced by traditional alternatives.
Emerging players
- Lemonade: AI-driven consumer insurtech offering homeowners, renters, pet, and life insurance with a digital-first, mobile-native UX. Comparable to WeatherPromise as a venture-backed insurtech challenger using technology to improve a traditional insurance experience, though operating in non-travel lines.
- Hippo Insurance: Insurtech focused on modernizing homeowners insurance with a tech-led, prevention-oriented product. Comparable as a venture-backed insurtech reworking a traditional insurance category, though targeting homeowners rather than travelers.
Broad incumbents
- World Nomads: Established travel insurance provider focused on adventurous and international travelers. Overlaps with WeatherPromise's traveler customer base and weather-related coverage use cases, but operates as a traditional claims-based insurance product.
- Allianz Travel Insurance: One of the largest global travel insurance providers, offering trip cancellation, interruption, and weather-related coverage. Comparable to WeatherPromise as the incumbent alternative for travel weather protection, though built around traditional indemnity claims rather than parametric guarantees.
- Generali Global Assistance: Global travel insurance and assistance provider offering trip protection including weather-related coverage. Comparable as an established travel insurance incumbent operating in the same broad product category as WeatherPromise's weather guarantees.
- AIG Travel: Major travel insurance carrier underwritten by AIG, offering trip protection and weather-related coverage. Comparable as a broad incumbent in the same overall market (travel weather/weather disruption protection) but with a traditional indemnity model and balance-sheet underwriting.
- Berkshire Hathaway Travel Protection: Travel insurance provider backed by Berkshire Hathaway Specialty Insurance, offering trip cancellation and weather-related protection. Overlaps with WeatherPromise on the traveler need for weather protection, though through traditional claims-based coverage.
Direct peers
- Sensible Weather: Boston-based insurtech offering parametric weather guarantees for travel, with payouts triggered automatically when adverse weather occurs. Most direct comparable to WeatherPromise in product, target customer (travelers), and B2B2C distribution model through travel platforms.
