Lunos Raises $5M to Deploy AI Agents That Handle Accounts Receivable Like a Human Colleague

"The $100T world of B2B commerce operates in a "Wild West" where businesses provide goods and services first and chase payment later - often for months. Despite decades of software innovation, the accounts receivable process still depends on millions of finance professionals manually sending emails, tracking down contacts, answering invoice questions, and reconciling incomplete payment data. With 57% of invoices paid late and 77% of AR teams falling behind, this communication and negotiation bottleneck has become one of the most persistent inefficiencies in the modern economy."

"Lunos is addressing this challenge with AI agents that manage receivables like a human colleague - reading customer histories, adapting tone and timing, handling two-way conversations, and working 24/7 without forgetting anything. Founded by Duncan Barrigan, former Chief Product Officer at European payments unicorn GoCardless, Lunos connects to existing tools like QuickBooks and NetSuite to automate the chase while maintaining personalized customer relationships. The platform offers both white-glove service and self-serve options, requiring no six-month integration process to start delivering value."

Lunos automates accounts receivable using AI agents that replicate human-like collections workflows by reading customer histories, adapting tone and timing, and conducting two-way conversations continuously. The AI operates 24/7, maintains memory, and handles negotiation and reconciliation to reduce late payments and manual labor. The platform integrates with existing accounting systems such as QuickBooks and NetSuite and offers white-glove and self-serve deployment options without lengthy onboarding. Lunos was founded by Duncan Barrigan and secured a $5M pre-seed round from General Catalyst and Cherry Ventures. The solution targets a $100T B2B commerce market with high late-payment rates and strained AR teams.
