Mobile, commerce & AI software

GMI Software builds business-critical mobile, commerce and AI-enabled software for companies that need ownership of their product, data and delivery budget. Based in Gdansk, Poland, we work with EU, UK and US companies as a product engineering partner, not a body-leasing vendor. We combine discovery, product design, architecture and delivery so clients understand scope, risks and technical trade-offs before committing to development. Core services: - React Native and Expo mobile apps for iOS and Android - Headless and B2B commerce, including MedusaJS, Next.js storefronts and custom checkout/order flows - Backend, API and system integrations with ERP, PIM, WMS, CRM, payments and legacy tools - Product Design, DDT workshops, prototypes and MVPs - AI agents, RAG knowledge bases and LLM integrations
