Witan Labs
AcquiredWitan Labs provides a headless application platform that enables AI agents to execute long-running spreadsheet operations on business-critical Excel files via a command-line interface. The platform emphasizes self-verification loops, allowing agents to inspect outputs before proceeding, and runs locally to maintain data control. Its technology has been acquired by GRID, which now offers similar spreadsheet tools to agents through an MCP server.

Problem
Long-running AI agents frequently produce outputs that require verification against real business files, yet most agent tooling lacks native compatibility with complex spreadsheet formats and reliable self-checking mechanisms. Teams that depend on accuracy—such as those in finance, operations, and data engineering—cannot afford silent errors when agents manipulate critical workbooks, leading to costly mistakes and limited agent adoption.
Solution
Witan delivers a headless application platform purpose-built for agents that must execute long-running tasks on business-critical files. The platform provides a command-line interface that agents can invoke directly to perform Excel operations such as creating sheets, adding data tables, generating charts, and rendering outputs to images. Witan's design emphasizes self-verification loops, allowing agents to inspect the results of their actions before proceeding, and ensures total compatibility with the files businesses rely on daily. The platform runs locally on the user's machine, giving teams full control over their data and workflows. Security is a core pillar, with SOC 2 Type II audited controls and HIPAA compliance baked into the infrastructure.
Target Audience
Primary users are engineering teams and AI developers building autonomous agents that must manipulate Excel files or other business documents with high accuracy, particularly in finance, operations, and data-heavy industries where correctness is non-negotiable.
Features
- Headless CLI (`witan xlsx exec`) enabling agents to execute spreadsheet workflows without a graphical interface
- Native support for complex Excel operations including cell updates, table creation, chart generation, and PNG rendering
- Self-verification loops that let agents check outputs and validate changes within the same execution context
- Local execution model with no cloud dependency, ensuring data stays on the user's own machine
- Free personal tier with no sign-in required for individual experimentation
- SOC 2 Type II certification and HIPAA compliance for enterprise security requirements
