Cellyn

Cellyn is an AI-powered Excel automation platform designed to transform how professionals interact with spreadsheets. Our mission is to eliminate repetitive manual work, reduce the technical barrier of complex formulas or VBA scripts, and deliver faster, more accurate insights in a fully secure environment.

Unlike generic AI assistants that rely on prompts or external cloud services, Cellyn is built for Excel-first workflows. It understands business context, learns from your existing templates, and executes tasks directly within Excel using formulas, VBA, or Python. Users can simply state their goals “generate a quarterly sales report in our company format”, and Cellyn delivers complete, reusable workflows aligned with established business standards.

Our initial focus is on finance, operations, and consulting teams that depend heavily on Excel but spend countless hours on manual reporting and data preparation. These teams risk errors, inefficiency, and missed opportunities due to outdated processes. Cellyn solves this.

With a „zero-prompt“ experience, behavioral learning, full formula traceability, and enterprise-grade security with local deployment options, Cellyn turns spreadsheets into an intelligent partner, helping organizations save time, improve accuracy, and focus on strategy.
