Overair is a startup that operates in the emerging electric vertical take-off and landing (eVTOL) market. The company is focused on developing a tiltrotor eVTOL, named Butterfly, which is designed to provide safe, quiet, fast, and affordable on-demand transportation. The Butterfly is built to carry a pilot, five passengers, and their luggage, making it a viable option for both personal and business travel.

Overair's business model is centered around the on-demand transportation market. The company aims to revolutionize the way people travel by offering a more efficient and environmentally friendly alternative to traditional modes of transportation. The Butterfly is powered by a fully electric powertrain, which means it produces zero emissions. This aligns with the growing trend towards sustainable and green transportation solutions.

The company's patented technology, developed over 15 years, has the potential to disrupt the traditional aviation industry. The Butterfly's unique features include 20+ ft propellers that are twice as large as any other eVTOLs, 200% excess power margins, and the ability to hover with only two of four propellers. These features, combined with the quad-redundant architecture on key systems, make the Butterfly a highly efficient and safe mode of transportation.

Overair's revenue model is likely to be based on a pay-per-ride basis, similar to other on-demand transportation services. However, the company has not yet disclosed specific details about its pricing strategy.

In summary, Overair is a promising startup that is poised to transform the on-demand transportation market with its innovative eVTOL technology.
