Product studio from Lviv building mobile, web and AI products
Kultrix is a product team in Lviv, Ukraine, building web and mobile products for clients worldwide. We build React Native apps, Next.js web apps and AI-powered applications, and we design UI/UX. Design, development, QA and project management in one team, from concept to launch. Mobile apps: cross-platform apps in React Native and native iPhone and iPad apps in Swift and SwiftUI, released on the App Store and Google Play. AI integration: LLM APIs, RAG pipelines and vector databases added to products a client already runs, and new AI apps and assistants on OpenAI, Claude and LangChain. UI/UX design: user research, prototypes, usability testing and design systems in Figma with tokens synced to code. Web, SaaS and MVPs: Next.js applications, multi-tenant SaaS platforms and MVPs taken from idea to launch. How we work: a 30-minute call, then a written scope with hours, a timeline and a budget range. Before estimating we build a clickable prototype, so the client can try the product before work starts. The code and repositories belong to the client from day one.2023
