Open Executive, an AI platform developed by SenteLabsAI, provides a virtual executive team that delivers business advice through a single interface. The platform includes eight specialist agents — chief strategy officer, chief financial officer, chief human resources officer, general counsel, chief operating officer, chief marketing officer, chief product officer, and board communications director — each responsible for defined functions such as market analysis, financial modeling, hiring, legal compliance, process design, go‑to‑market strategy, product roadmap planning, and board reporting. User messages are processed by an Executive Orchestrator that invokes the default Claude Sonnet‑4.6 model for routine tasks and the Claude Opus‑4.7 model for deep‑reasoning specialists; each specialist retrieves relevant context from a ChromaDB vector store that contains built‑in MBA‑level knowledge and uploaded company documents. The system maintains episodic memory and a scheduler that triggers follow‑up actions, both stored in a local SQLite database, and operates under a single‑instance constraint to ensure scheduler consistency. The backend is implemented in Python 3.11 with FastAPI, and the web UI uses Next.js 15 with Tailwind. The source code is released under the Apache 2.0 license and is deployed on Fly.io, where two environments (dev and qa) run separate API and UI applications that share a read‑only volume for persistent data. Users can interact via a web interface, Slack, email, Telegram, Google Chat, or Discord, and can upload company documents through the UI or command line. The initial setup requires cloning the repository, configuring an Anthropic API key, and running a development environment that starts the API on port 8000 and the UI on port 3000.
