Sabi today opened its founder waitlist for a new kind of AI personal assistant: an AI chief of staff built for small-business founders who want to delegate real work over a simple text message instead of learning another complicated software. Unlike reactive AI chat tools, Sabi is a proactive AI executive assistant that can start handling busy work in Outlook, Microsoft 365, Google Workspace, and common CRM and accounting systems founders already use, then runs the business alongside them.
Co-founded by Stephen Diaz and Bruce Van Zyl, Sabi is positioned squarely at a segment the current AI-for-founders category has overlooked: non-technical Gen X business owners running successful companies who don't want another app, another login, or another prompt engineering course. Sabi is delivered as an actual "hire," not a tool. The company offers a free internship plan so business owners can experience having Sabi as their AI assistant before committing to bringing her on the team.
Sabi's core capabilities include:
- AI inbox triage for Outlook and Gmail. Screens incoming email, surfaces the top three messages that need a human reply, and drafts responses in the founder's voice. Early reports have shown Sabi cutting inbox time by up to 80%.
- AI calendar assistant and scheduling. Handles AI meeting scheduling across Outlook and Google Calendar and delivers a prep brief 10 minutes before every call.
- Live financial visibility. Pulls reconciled P&L, cash flow, and runway from Stripe and QuickBooks on demand — texted back as a PDF.
- Content in the founder's voice. Drafts social posts, emails, and ads using the founder's real writing patterns.
- Persistent memory. Every conversation, decision, and SOP compounds. Sabi learns flagged clients, forgotten tasks, and how the founder likes things done.
- Night Shift. While the founder sleeps, Sabi re-reads SOPs, indexes email, and prepares the morning brief to set the business owner up for success the next day.
Built for trust from day one. Sabi is designed for founders who are cautious about giving AI access to their inbox, calendar, and finances. Every customer's data is walled off at the database layer with Row Level Security. Connections to Gmail, Outlook, and Google Calendar happen through OAuth — Sabi never sees or stores passwords. A deterministic approval gate, hard-coded outside the AI itself, prevents Sabi from sending an email, replying to a message, or posting on the founder's behalf without explicit approval. The platform runs on SOC 2-compliant infrastructure (Supabase, Stripe, DigitalOcean), with Sabi's own SOC 2 Type I audit in preparation.
Sabi estimates a typical founder will save more than 1,100 hours per year having an AI executive assistant — approximately $165,000 in reclaimed founder time on average.
