About the Company

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-powered software testing automation platform. 

In October 2019, we officially released Autify for Web, our test automation software that targets web applications. Also, in October 2021, Autify for Mobile for mobile app testing was officially launched, and we closed our $10M Series A. Although the product lineup is continuing to expand, and we have been able to provide all basic functions needed in a test automation platform, we continue to receive requests for new features and improvements.

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 the Engineering Team

Our Team

Autify's engineering team is international, with more than half of the engineers being foreign nationals and all developers being English speakers. We have a good culture where members respect each other's backgrounds. Since we have two products, Autify for Web and Autify for Mobile, our development engineers are divided into two teams corresponding to each product. We have about 30 front-end, back-end, and technical support engineers who work closely with engineering managers, product managers, QA managers, designers, and machine learning engineers. The product manager is in charge of the general roadmap. The product manager develops a rough roadmap and works with the engineers and designers on the details of each feature and bug fixes before implementation. Depending on the size of the feature, we appoint a feature lead from among the engineers to be in charge of the project and give them the discretion to make technical decisions.

Our Development Process

We create a ticket about what kind of function we will develop. In some cases, the product owner creates it based on user feedback; in other cases, each team creates bugs and investigation requests directly. 

The development cycle consists of one Sprint, which takes two weeks. Development tasks are assigned during the planning stage on the first day of the Sprint, and we hold a daily standup meeting to check the overall progress and any problems. (If there is a time difference, it is done at lunchtime).

We review code on GitHub. After the review, the merged branches are automatically deployed to the staging environment, and E2E tests are performed (which Autify does itself).

After testing on the integrated branch, it's deployed to the production environment. Deployment is done several times a week as needed. We also hold sprint ceremonies like Sprint planning, feature refinement and sprint retrospective sessions. The developer will demonstrate the developed function to all employees at the end of the Sprint in the Sprint Demo.
