The Weather Company's 130 meteorologists now run on a stack rebuilt with Vercel and v0, recalculating 2.2 billion coordinates every 15 minutes.

The Weather Company now serves forecasts to **350 million** monthly active users worldwide on a web stack and CMS rebuilt on [Vercel](<https://creatorstoolbox.com/tools/vercel>) and v0, according to a [new case study](<https://vercel.com/blog/how-the-weather-company-serves-real-time-forecasts-to-350-million-daily-active-users-on-vercel>). The company's roughly 130 meteorologists track weather systems that feed into 2.2 billion coordinates recalculated every 15 minutes.

The rebuild cut the path from a design to a published web page from days to hours, an 80% increase in velocity, and turned work that once took years into months.
