On January 16, 2018, GFPUT (a temporary name) was launched to study a one passenger electric vertical and takeoff (eVTOL) aircraft. In June 2018, teTra Aviation Corporation was established by Yui Nakai, President, and a doctoral student at the University of Tokyo. The company started with ¥1 million in and went on to raise ¥50 million to continue their work.

teTra Aviation Corporation has participated in all phases of the GoFly Prize contest and was selected as a Phase I winner on June 14, 2018. On February 29, 2020, Team teTra won the $100,000.00 USD Pratt & Whitney Disruptor Prize for its teTra 3 hybrid-electric vertical takeoff and landing (VTOL) aircraft at Moffett Federal Airfield at the NASA Ames Research Center. Due to windy conditions in February, many teams competing during the Phase III trials did not fly their aircraft and as of February 2020, the the $1 million GoFly Prize has been postponed.

The company has stated they want to manufacture and sell their 1.65 m high (5.4 feet) X 2.2 meters wide (7.2 feet) X 2 meters long (6.6 feet) one passenger aircraft to people around the world. The pilot gets on the aircraft the same way a person does when getting on a motorcycle.

In addition, the company’s website states they are also in the business of consulting, design, research and development, and prototyping eVTOL aircraft. The company’s goal is to market and sell their aircraft by 2025.
