## About

We build AI systems that work in production, not just in demos. We deliver through a forward-deployed engineering model: senior engineers embedded with your team, shipping to production on your data. On-premises and air-gapped deployments supported, and direct access to the team without account managers in the middle.

Flagship work includes a legal document review platform with a custom RAG framework and citation-grounded retrieval, an AI tax advisor built on LangChain for Dutch fiscal compliance, an agentic productivity tool with dynamic interfaces and autonomous task execution, and an AI-powered TMS that cut dispatcher workload by processing loads and emails autonomously.

Key outcomes across projects: 60% reduction in legal research time, 95%+ document accuracy, 70% drop in support resolution time, 3.2× ROI in Year 1.

Our AI stack: LangChain, OpenAI and Anthropic APIs, pgvector, Qdrant, Pinecone, Weaviate, Mastra AI, Cohere, FastAPI, Next.js, TypeScript, Python. For healthcare clients, we deliver HIPAA-compliant, FHIR/HL7-compatible systems with full audit trails and access controls. For content-driven applications, we build on Payload CMS and Next.js, headless, composable, and production-ready.

88+ products shipped. Clients range from early-stage startups to enterprise, including Porsche and Translink, across Legal, Healthcare, SaaS, Logistics, and Financial Services.
