We Build Ruby/Rails Applications
in an Agile Way

Make both customers and developers happy; that is the most important goal of our activities.

We have been successfully helping build hundreds of software products and solid relationships with our customers over the past decade.

Our Values

We build software for business needs through collaboration with customers. We believe development activities should be based not only on technologies but also on a deep understanding of each business and its end-users.

Marketable
Product

We do not only code but also pursue a marketable product with customers. We will suggest the best possible way to achieve business objectives based on our practical knowledge which has been cultivated through 10 years of Ruby/Rails experience.

Adequate
Quality

Resources are always limited. We balance the schedule and the scope to make the product feasible and adequate. When we find a problem, we propose a reasonable way to solve it. At the same time, we do not compromise on suitable quality.

Maintainable
Code

We provide "clean code that works" so that the product be maintainable and sustainable. We are ready, skilled, and eager to make every effort for that.
