Solid Factory Co., Ltd. was founded in Osaka in 1997. Over 25 years, we've evolved from packaged software development into a full-stack engineering studio — building custom e-commerce platforms, business applications, and cloud infrastructure for clients across Japan and beyond.

Our engineering lead has shipped production code at scale — including e-commerce solutions for one of Japan's largest apparel retailers. That enterprise-grade discipline now serves companies of every size, with the communication clarity and speed of a small team.

We use AI-augmented development workflows to deliver significantly faster than traditional agencies. You get senior engineering judgment, modern tooling, and a direct line to the people writing your code.

From building web sites for major apparel companies to delivering enterprise-scale solutions, we bring enterprise-grade discipline to every project. Our strength is offering the speed and flexibility of a small team with the rigor of a large organization. We prioritize usability and practicality, delivering finely tailored customizations that fit each client's operational workflows. Backed by a quarter century of experience, we support businesses of every size.

We now actively leverage the latest AI development tools to deliver projects faster and at lower cost than traditional agencies. Experienced engineers work directly with you to tackle challenges together. With cutting-edge technology and a quarter century of track record, we continue to support our clients' businesses from Osaka.
