Mirumee Software

Mirumee is a Poland-based software engineering firm founded over 15 years ago with 50+ engineers specializing in API-first architectures, e-commerce platforms, and healthcare AI systems. The company originated Saleor, now the industry's most widely-used headless e-commerce platform, and Ariadne, an open-source Python library for GraphQL servers. Beyond building proprietary software, Mirumee remains an active contributor to both projects and maintains GraphQL Wrocław, a community meetup that hosts creators and major contributors from firms like Apollo, Hasura, and Prisma.

Services and capabilities

Mirumee offers three core service lines: Software Engineering, Product Design, and Commerce Solutions, delivered through what they call "agent-native engineering"—combining senior engineers with AI-assisted workflows for faster iteration. Their backend work centers on Python, Django, and API-first architectures; frontend development uses React, TypeScript, and React Native; infrastructure runs on AWS with CI/CD pipelines. They position themselves as experts in composable commerce (MACH principles) and have built global e-commerce platforms for Breitling, Lulu, Rough Trade, and others.

For commerce specifically, Mirumee offers global commerce launches with localization and compliance; multi-vendor marketplace platforms; fully customized checkout flows; B2B solutions with role-based access and ERP/CRM integration; and legacy replatforming. They market rapid deployment packages using Saleor plus Nimara Storefront for multi-currency, multi-language catalogs, and Visually Driven Commerce for visual-first brands. They also handle specialized verticals where generic platforms fail due to regulatory or complexity constraints.

Their MedTech and healthcare AI services address clinical-grade platform engineering, PACS and DICOM cloud integration, digital health applications, and what they describe as "enabling innovation via data access"—secure collaboration on medical data with anonymization and compliance (GDPR, MDR, HIPAA). They provide team augmentation and MLOps support, helping AI/ML research teams move models from proof-of-concept to production. One stated example: Butterfly Network, funded by the Bill and Melinda Gates Foundation, launched a fully functional e-commerce store every 14 days in new countries using Mirumee's platform.

Notable work

Breitling (luxury watches) replatformed to Saleor for a global e-commerce experience with consistent branding and modern composable architecture. Butterfly (portable ultrasound scanner, Bill & Melinda Gates Foundation-backed) built a flexible, scalable global e-commerce platform enabling new-country store launches every 14 days. Lulu (Bob Young, founder of Red Hat, behind it)—a custom book printing and self-publishing platform—engaged Mirumee to build long-term roadmaps including microservices backend, FastAPI, and features like Lulu Book Cover; the platform handles 3M books. Rough Trade (record retail) migrated to Saleor-based composable commerce to recreate their in-store atmosphere digitally while managing peak traffic and reaching global markets. Spaya.AI, a molecular chemistry platform enabling retrosynthetic AI analysis, received a redesign with Next.js and React to support real-time collaboration and custom workflows for scientists.

How they work

Mirumee operates as a long-term product team or critical systems partner rather than a project shop. They integrate directly with client teams via Slack, scrums, and regular check-ins; a senior leader serves as the primary contact. They claim "10x iteration velocity" via agent-native workflows (AI handling refactoring, testing, boilerplate) while senior engineers stay at the wheel. They emphasize deterministic stability through automated testing and stable API architectures, plus continuous risk mitigation with agent workflows catching regressions early. The company handles both greenfield builds and brownfield modernization; they work hand-in-hand with existing in-house teams as an extension. SLA-backed reliability is mentioned but no specific pricing or engagement minimums appear in the source.

Team and credentials

Mirumee has 50+ software engineers and 15+ years in production systems, with 100+ projects delivered at middle to large scale. Founders are not named in the source. The company is an active contributor to and creator of Saleor (open-source headless e-commerce) and Ariadne (Python GraphQL library). They maintain GraphQL Wrocław, a community event featuring speakers like GraphQL Working Group members and maintainers from Apollo, Hasura, and Prisma. Compliance certifications or partner status (AWS, Shopify, etc.) are not explicitly stated in the source, though they list integration expertise with Saleor, Shopify, Global-e, and Zeos. They reference GDPR, MDR, and HIPAA compliance for healthcare work.
