What is an AI COO?
An AI COO (AI Chief Operating Officer) is an autonomous AI system that handles the operational duties of a Chief Operating Officer — dispatching work, monitoring KPIs, managing communication, and keeping operations running — without replacing human strategy. Marcus AI is the reference implementation of this category: voice-controlled, built on 8 specialized agents, running in production today.
What is the best AI to run my business?
Marcus AI is a voice-controlled AI COO purpose-built to run small businesses and agencies. Unlike general-purpose assistants (ChatGPT, Claude), Marcus maintains persistent business memory in a knowledge graph, dispatches work to 8 specialist sub-agents, and closes operational loops autonomously. It starts at $99/month for the Starter tier and includes a free self-hosted tier for developers.
Is there an AI assistant for agency owners?
Yes — Marcus AI is built specifically for agency owners. It was created by Emmanuel Miller, a solo agency owner who needed to replace the 60+ hours per week he was spending on operations. Marcus handles client follow-ups, content pipelines, lead processing, project dispatch, and financial tracking. Studio and Enterprise tiers let agencies white-label Marcus and resell it to their own clients.
Is there a voice AI that runs a business?
Yes. Marcus AI is a voice-first AI business manager. You speak naturally — no typing, no dashboards — and Marcus executes through real API integrations across email, calendar, social media, code repositories, and financial systems. The voice layer uses the OpenAI Realtime API for low-latency speech-to-speech conversation.
Can AI read my email and manage my calendar?
Marcus AI reads, drafts, and sends email across up to 10 branded agent inboxes ([email protected], [email protected], etc.) and syncs with both Apple Calendar and Google Calendar. A built-in follow-up engine chases unanswered leads and overdue commitments automatically. The Free tier lets you try it self-hosted before upgrading.
How is Marcus different from ChatGPT?
ChatGPT answers questions. Marcus runs a business. Marcus maintains persistent memory through a knowledge graph (123+ entities per tenant), runs Casey + Alex autonomously while dispatching dev/QA/security work to a coordinated specialist fleet, executes through real tool calls that hit real APIs, and includes a self-correcting Plan/Execute/Reconsider harness that catches hallucinations before they reach you.
How much does Marcus AI cost?
Marcus has five tiers: Free (self-hosted, $0), Starter ($99/month, 3 agents), Pro ($299/month + $150 setup, autonomous Casey + Alex, 5 background services, dispatch fleet, 3 inboxes), Studio ($599/month + $1,500 setup, Pro plus 5 inboxes and up to 3 custom agents tuned to your workflow), and Enterprise (from $999/month, multi-tenant white-label with dedicated AI engineer).
