They’re building several in-house products such as Colorkrew Biz, which is a business concierge service that solves administrative issues using QR and authentication technologies, and Goalous, a social network for companies that focus on managing company goals like OKRs.

They also do consulting work across a wide variety of areas such as cloud integration, marketing and promotion, payments, server architecture and more. Colorkrew’s development team is made up of talented people from many different countries, and they maintain a vibrant, international environment. It’s also one of the first companies in Japan to adopt a truly flat hierarchy, eliminating all job titles and departments in order to maximize the impact of each individual. At Colorkrew, they have a culture that values employee autonomy, and flexibility.

They want their employees to be able to do their best work, so Colorkrew allows remote work, as well as “20% time” as long as you complete your scheduled work. They also have some great benefits. Thanks to their supportive company culture that fosters growth and teamwork, the average tenure of their engineers is about 5 years, which is much longer than most tech companies in Japan. This is a testament to how much people enjoy working at Colorkrew.

They also hire new graduates and interns to work on their engineering team, which is relatively rare for companies hiring non-Japanese engineers and candidates from abroad (most companies limit their overseas hiring to more experienced positions). We think this could be a great opportunity for someone who wants to start their engineering career in Japan and work alongside talented senior engineers to gain experience while also experiencing Japan!
