| Global Market for QA

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. 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.

| About Us

Autify, Inc. is a San Francisco-based startup that was founded by the first Japanese team to graduate from Alchemist Accelerator, one of the top accelerators in the US. With the mission to empower people’s creativity through technology, we have been offering an AI-powered testing platform since 2019.

As AI is reshaping the software development process, we have just launched Aximo, the first AI tester that executes a test based on natural language processing and visual recognition.
