Our team includes Software Engineers, Machine Learning Engineers, Product Managers, and Designers who work together to advance AI-driven customer support. Our main focus is building an AI Agent that can accurately and efficiently respond to customer inquiries and drive sales!

As a company: We serve 15K+ e-commerce businesses. We handle 1M+ merchant-shopper interactions per day. We recently raised a $30 million Series C (Crunchbase article). The machine learning solutions we have built are already embedded in the product: A state-of-the‑art agentic LLM pipeline that crafts answers and executes e-commerce actions, bringing value to both Gorgias and our customers at scale. Relies on multiple providers, including in-house fine‑tuned models. Uses A/B testing to validate prompt engineering. Includes a retrieval‑augmented generation (RAG) system that contextualizes customer requests using ANN, rerankers, feedback loops, and knowledge graphs. Classical NLP classification algorithms that identify non-support-related emails, detect intent, and infer customer sentiment. Clustering based on minimum-cost flow problems to discover new knowledge resources from non-automated interactions. A product recommendation system that drives sales and conversions on merchant websites.

AI at Gorgias

At Gorgias, AI is a natural extension of how we work and build. Our teams use it every day to research, write, analyze, code, and craft better customer experiences. Everyone has access to premium AI tools (ChatGPT, Claude, Granola & others) and an annual L&D budget to explore new ones.

The real magic happens when we share what we learn. Our #powerup Slack channel is a digital petri dish of new tools and workflows, and each team has AI champions who showcase fresh ideas during weekly company‑wide standups, now practically AI demo sessions.

We see AI not as a replacement for creativity or empathy, but as a multiplier, helping us move faster, think deeper, and serve customers better.
