WindBorne Systems is a startup that operates in the atmospheric data collection market. They use high-tech balloons to gather valuable data from different layers of the atmosphere. The balloons are fully controllable, allowing the company to collect specific "slices" of atmospheric data repeatedly with a single balloon.

The company's clients are likely to be organizations and businesses that require atmospheric data for various purposes. These could include weather forecasting agencies, climate researchers, environmental monitoring organizations, and potentially even aerospace companies.

WindBorne Systems' business model revolves around the collection and sale of atmospheric data. They make money by providing their clients with access to this data, which is collected from various altitudes and locations around the globe. The company is continually launching more balloons to expand their data collection capabilities.
