Real challenges we've solved for our clients
Order management, inventory, and billing were scattered across separate systems and spreadsheets, causing duplicated stock tracking and frequent transcription errors. The client also needed a single view of inventory across other order-taking services.
Built a multi-tenant SaaS that consolidates orders, inventory, billing, and printable forms in one screen. CSV / API integrations bring stock from other services into a single hub, and an XML migration tool moves data from the existing C# WinForms application smoothly.
Custom-built band websites typically required hundreds of thousands of yen up front plus ongoing maintenance cost, making it hard for emerging bands to launch an official site.
Built a template-sharing SaaS with Stripe Connect for end-to-end merchandise sales. Bands can launch a site on a custom domain from ¥1,980 / month.
A band relied solely on social media for information sharing and fan communication. They needed an official website to centralize live event info, merchandise sales, news, and media in one place.
Built an official site matching the band's visual identity, consolidating news, live event info, and merchandise sales into one place. Also implemented an admin panel so the band can update content themselves.
Daily operations involved excessive manual data entry and repetitive tasks in Excel, leading to wasted hours and frequent human errors.
Analyzed business workflows and automated repetitive manual tasks using Excel macros and functions.
English learners wanted a dedicated app for practicing instant English composition anytime, anywhere. Existing apps didn't meet their specific training needs.
Developed a learning app with level-based decks and flashcard format so users can practice instant English composition anytime, anywhere.
English learners had no easy way to get feedback on their diary writing. They needed a tool that could instantly correct grammar, vocabulary, and expressions.
Developed an AI-powered English diary app that provides real-time corrections on grammar, vocabulary, and style. Also features handwriting scanning (OCR) and automatic flashcard generation from AI corrections.
