Custom software, built around your business
E-commerce platforms built from scratch around your exact business logic — pricing rules, inventory workflows, multi-channel selling, whatever your model demands. No templates, no compromises.
Internal tools that replace spreadsheets and manual work — dashboards, inventory systems, approval workflows, client portals. Software that fits how your team actually operates.
When off-the-shelf doesn't fit, we build it. From niche SaaS products to specialized integrations, we turn your specific business requirements into working software.
Keep it running, keep it fast
We design, deploy, and manage the infrastructure your applications run on — so your team never has to think about servers, uptime, or scaling.
Monthly retainers for continued development, bug fixes, performance tuning, and new features. Your software stays healthy and evolves with your business.
Senior technical guidance, no enterprise overhead
Architecture reviews, technology decisions, scalability planning — senior engineering judgment for your biggest technical questions.
We integrate AI into our development process to deliver meaningfully faster than traditional agencies. Same senior-level quality, shorter timelines.
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.
