Sidetrade’s autonomous AI collections agent, Aimie, has landed its first announced US enterprise account. Industrial testing and inspection company Mistras Group is using the tool to run its accounts-receivable outreach without a human dialer. The agent draws on Sidetrade’s Order-to-Cash data lake, which the company says holds close to $10 trillion in B2B transaction history across roughly 45 million buying companies, to decide who to contact, how to phrase the ask, and when to escalate.
Aimie does not simply send reminder emails. Per Sidetrade, it makes context-driven calls, qualifies which invoices are genuinely disputed versus simply late, and adjusts its own collection strategy as it learns a customer’s payment behavior over time. Revenue platforms have spent the back half of 2026 racing to unify pipeline and forecasting data into one system, but collections has mostly sat outside that push. Sidetrade is applying the same automation logic to the account rather than the deal.
That is the more interesting signal for revenue leaders than the Mistras logo itself. Most of the autonomy vendors have granted AI agents this year has gone to deal-facing work that sales reps are often reluctant to hand over. Chasing overdue invoices is a job nobody on a revenue team actually wants, which means the collections category may see less internal resistance and a faster path to full autonomy than seller-facing agents, simply because there is no incumbent role defending the task.
Sidetrade, which runs the deployment from a base of roughly 450 employees across Europe, North America, and Asia-Pacific, says it now supports customers in 85 countries on the strength of that transaction data lake. Scale is the actual product being sold here: the more B2B payment behavior Sidetrade has already seen, the more confidently Aimie can guess which excuse a late payer is about to give before the call even connects.
