About Autify

Autify, Inc. is a start-up company founded in San Francisco by a team of engineers who were the first Japanese team to graduate from the top US accelerator Alchemist Accelerator. With the mission to increase creativity with the power of tech, we develop and provide Autify, an AI-based software test automation platform.

Markets are changing rapidly, and there is a demand for quick software releases. Agile development has become mainstream; on a global scale, 92% of developer teams adopt agile development, 71% of which aim to release at least once a week. With such a rapid cycle, manual verification is too time-consuming, and there is an urgent need for automation. Our services can solve these critical challenges and make our clients a competitive advantage in software development.

Over 300 companies have begun using their service since its official release in October 2019, and that number is continuing to grow.

QA’s global budget is said to reach over $1 trillion. We are rapidly expanding our service reach internationally to win this vast global market.
