About the Company

Company description We’re an early-stage, founder-led team in San Francisco building AI agents that replace legacy ERPs for distributors and mid-market operators. Our platform connects order capture, inventory, purchasing, invoicing, and analytics—integrating with systems like NetSuite/SAP/QuickBooks and modern ecommerce—so ops teams can move from spreadsheets and tickets to automated, real-time workflows. We sit with warehouse and supplier teams, ship quickly, and measure everything (latency, accuracy, and cost per request) to keep the product production-grade.
