WeatherPromise Secures $12.8M in Series A Funding

Weather has always been the quiet kingmaker in travel. It decides whether memories glow or turn gray. It shapes demand, regret, delight, and refunds, all without asking permission. For decades, the industry shrugged and called it uncontrollable. WeatherPromise saw that shrug as a lazy assumption. New York grit, Berlin precision, and a refusal to treat weather like fate. Founded in January 2022 by Daniel Price and David Klemm, this company decided weather deserved math, not excuses.

WeatherPromise just locked a $12.8M Series A, more than 3x oversubscribed, led by Maveron, a firm that studies consumers the way meteorologists study pressure systems. Dan Levitan joining the board is not a headline grab. It is signal. Lerer Hippeau, Clocktower Ventures, Commerce Ventures, MS Transverse, Start Ventures, 1Sharpe, and 1Flourish leaned in, alongside Mark Okerstrom, former Expedia Group CEO, who knows exactly how weather quietly murders conversion at scale.

This is not guesswork wrapped in branding. WeatherPromise processes 400M+ weather observations daily across 2.3M locations in 95 countries. Quotes generate in milliseconds. Roughly 15k per hour. One July day alone saw 62,018 guarantees issued. This is infrastructure disguised as simplicity. Embedded directly into checkout flows, the product shows travelers precise conditions upfront and pays automatically when reality crosses the agreed line.

Daniel Price runs distribution and partnerships with a CEO's sense for leverage. David Klemm brings CFO discipline and quantitative rigor that keeps the engine honest when volume spikes. Together, they built a B2B2C model that lets Marriott, JetBlue, Expedia, and HomeToGo turn hesitation into confidence, especially during shoulder seasons when weather anxiety quietly stalls bookings.

Every guarantee is backed by Greenlight Re, because promises mean nothing without balance sheet muscle. What customers feel is trust. A 4.4 rating on Trustpilot does not come from clever copy. It comes from refunds that land fast, clean, and without paperwork or arguments.

Scott Mayerowitz shapes narrative and strategy as Head of Travel, translating weather science into human language. Ilya Blokh sharpens the product. Neil Ahlsten brings investor perspective through 1Flourish. Berlin engineers keep latency tight while New York pushes partnerships forward.
