About Weather Source

Weather Source was founded to help clients leverage weather and climate technologies for business intelligence. In 2015, we started development of the OnPoint Platform and in 2017 we released the first versions of the OnPoint data products. Since then, we have provided weather and climate insights to the majority of Fortune-ranked companies.

Our mission is to make hyper-local weather and climate data accessible around the globe and across industries.

Our passion is working with companies to leverage weather and climate data to develop weather strategies that ultimately reduce waste, increase ROI, fine-tune logistics, optimize marketing strategy, and improve resource planning.

In the U.S. alone, weather accounts for more than $600 billion a year in lost revenue. The Weather Source team brings breadth of industry knowledge with a combined 75 years of meteorology and climatology expertise. We are data experts dedicated to developing advanced, high-quality, and easy-to-use products and services that empower businesses.
