Minimal is a company that leverages the LangChain ecosystem to transform e-commerce customer support by delivering 80%+ efficiency gains and improving customer satisfaction. They have developed a multi-agent system that integrates seamlessly with popular helpdesk tools, automates customer interactions, and executes order management tasks while maintaining tight control over business protocols. The system consists of three main agents: Planner Agent, Research Agents, and Tool-Calling Agent, which work together to break down complex queries into sub-problems, retrieve relevant information, and execute decisive actions. Minimal has extensively tested their system using LangSmith, which enabled them to track model responses, run side-by-side comparisons, log each sub-agent's output, and catch anomalies. The company chose LangChain and LangGraph due to their modular design, integration hooks, and future-proofing capabilities. With a small but growing team, Minimal aims to expand across Europe, earning revenue from Dutch e-commerce clients who appreciate faster ticket resolution and advanced features like automated refunds.
