Lumari is an AI-native procurement automation platform purpose-built for direct materials and supply chain execution. Through its platform, Lumari (https://www.lumari.io/) deploys hundreds of always-on AI agents—"digital workers"—that run sourcing workflows, manage RFQs, expedite purchase orders, extract and normalize supplier quotes, and coordinate supplier communication end-to-end, without the manual chase that typically buries procurement teams in email and spreadsheets.
Lumari stands out by acting as a "system of action" rather than just another system of record. Instead of dashboards that only monitor a supply chain, Lumari's agents actually do the work: following up with suppliers, capturing PO confirmations and delivery status updates, comparing bids, and escalating risks early. The platform layers directly on top of a company's existing ERPs, email, Slack, and spreadsheets—with no rip-and-replace migration and, critically, no supplier onboarding or portal required—so the supply base never has to change how it works.
Teams leverage Lumari for a range of procurement use cases, such as:
RFQ automation and supplier sourcing Quote extraction and normalization from PDFs and email Purchase order tracking and confirmation chasing Delivery monitoring and proactive risk escalation
By focusing on direct procurement—the daily operational grind that enterprise suites were never built to handle—Lumari addresses a significant gap where buyers spend the bulk of their day copy-pasting between email, spreadsheets, and ERPs. Teams stay in control through configurable guardrails and approval layers on every action, and agents learn from corrections over time to deliver more consistent results without reconfiguration.
How Was Lumari Started?
Lumari was founded in 2025 by Sam Lamba and Eshani Mehta. Sam Lamba, formerly an engineering lead at Google, led the development of AI-driven products that scaled to millions of weekly enterprise users and holds two AI patents. His background also includes engineering roles at Tesla and Amazon. Eshani Mehta previously led payments intelligence products at Stripe, working on systems processing hundreds of millions in volume, and held positions at Robinhood and Snap. Both founders have technical backgrounds from Duke University and UC Berkeley, respectively. They built Lumari after recognizing that supply chain teams remain stuck in reactive "firefighting" mode—where a single delayed component can halt a factory or kill a product launch—because legacy tools were built for tracking, not doing. Lumari is part of Y Combinator's 2025 (X25) batch and is based in San Francisco.
Who Uses Lumari?
Lumari is designed for direct materials procurement and supply chain teams—particularly manufacturers, hardware companies, and any business managing complex spend across many suppliers. The platform serves organizations ranging from Fortune 500s to fast-growing startups that need to automate work from sourcing to delivery, streamline supplier communication, and bring full visibility to their procurement operations. Lumari partners closely with each customer to adapt its agents to their specific processes, approval chains, and systems of record.
What Problems Does Lumari Solve?
Buyers spending the majority of their day on manual supplier emails, follow-ups, and spreadsheets Missed dates, delays, and lack of visibility that drive costly expediting and production delays Enterprise S2P suites and ERPs that handle spend management but never touch daily PO tracking and supplier chasing The supplier-adoption problem, where a large share of the supply base never logs into a portal or new platform The need to move teams from reactive risk response to proactive, always-on monitoring
Competitive Landscape
The AI procurement space splits into two camps that often work together. Large enterprise spend-management and source-to-pay suites—SAP Ariba, Coupa, JAGGAER, GEP SMART, and Ivalua—dominate contracts, compliance, and analytics for big organizations but were not built for the daily operational grind of direct materials. Lumari competes in the newer AI-native execution category alongside players such as SourceDay (PO change management inside the ERP), Keelvar (autonomous sourcing bots for complex bidding events), Leverage AI (ERP-native PO automation), and Sustainment SRM (supplier relationship management for defense and aerospace). Other adjacent and point solutions include Mandel, Zip (intake management), Pactum (autonomous tail-spend negotiation), and Suplari (procurement spend intelligence). Lumari differentiates by running the full procurement cycle through email with no required supplier portal or onboarding.
