About Us
INZENYR LLC is a development company built around iOS app development, with strengths in AI adoption and legacy system modernization. We integrate the latest technologies — generative AI foremost — precisely into products, and renew aging, bloated systems into a form ready to carry future business. With iOS at the center, we treat the servers, APIs, and business systems behind it as one whole, supporting the full cycle from planning and design through implementation, operation, and improvement. Drawing on extensive experience localizing and culturalizing overseas apps and games for the Japanese market, we also strongly support clients bringing overseas services into Japan. From games to large-scale financial and enterprise systems and embedded development, we bring more than 25 years of cross-disciplinary expertise to give solid shape to what you want to build.
// Vision
AI and mobile — the next step for your business.
We don't treat “adopting” AI or mobile technology as the goal in itself. We care about the experience of the people on the other side, and about our clients' business outcomes. We bring continually evolving AI into forms usable on the ground, and turn legacy assets from liabilities into strengths. Supporting resilient product development with the speed and quality only a small, senior team can offer — that is the kind of development we aim for. Leveraging collaboration with development teams at home and abroad and our knowledge of culturally aware localization, we also devote ourselves to solving challenges across borders.
