Monto is an AI-driven accounts receivable automation platform that helps B2B finance teams get paid from any accounts payable (AP) portal used by their enterprise customers. The platform provides AI agents that automate portal interactions, submit and track invoices, verify data, integrate with ERP systems, and centralize payment workflows, allowing finance teams to reduce manual effort, minimize errors, and accelerate collections. The company's core value proposition addresses a growing problem in global commerce: as more than 80 countries have established e-invoicing mandates or continuous transaction control requirements, suppliers must integrate with each customer's payment software—each with its own complex logins and workflows—creating endless chaos for payment collection teams that severely impacts cash flow and working capital. Monto's AI platform learns each customer's invoicing requirements and ensures a seamless payment flow. The platform has helped suppliers get paid nearly $1 billion, with clients including Shutterstock, TechTarget, and G2. Monto was founded in 2021 and is backed by seven investors. The company recently raised $9 million in seed funding and established a new office in New York City. As of 2026, the company employs approximately 109 people.
