Tesorio
Tesorio was founded in 2015 by Carlos Vega and Fabio Fleitas, who built the company after graduating from Y Combinator. The founders observed that accounts-receivable teams at fast-growing businesses were buried in manual collections, cash-application guesswork, and spreadsheet forecasting. The firm has since positioned itself as a Connected Financial Operations platform that targets the gap between a signed contract and collected cash. Tesorio's AI agents handle collections, cash application, and supplier-portal management. Collections agents draft personalized dunning emails, extract payment promises from replies, and detect invoice disputes. The cash-application engine matches incoming payments to open invoices; the firm reports a 95%+ auto-match rate across more than 200 customers. Supplier-portal agents submit invoices to Coupa and Ariba, then track payment status and download remittance data. Named customers include GitLab, where teams save 15 hours per week, Veeva Systems, which reported a 50% reduction in 90-day aged receivables, and Smartsheet, which exceeded a $14 million cash goal using the platform. The firm serves its enterprise base with pre-built integrations for NetSuite, Sage Intacct, Workday, Salesforce, and Stripe. The firm's website does not disclose AUM, total team size, or revenue. It publishes aggregated customer outcomes: an average 33-day DSO reduction, a 98% retention rate, and a claim that customers reduce 90-day aged receivables by half. The platform includes an ROI calculator that illustrates modeled working-capital unlock. In September 2023, Tesorio earned its third Deloitte Technology Fast 500 recognition, an award given to the fastest-growing technology companies in North America. The structural differentiator is the firm's insistence on purpose-built financial-operations AI that carries an audit trail. Tesorio states its models are prohibited from fabricating invoice amounts, PO numbers, or dates — a governance posture that sets it apart from general-purpose enterprise copilots. The platform operates under SOC 1 and SOC 2 compliance and keeps client data out of model training, meeting the sign-off requirements of enterprise CFOs.

Frequently asked questions
What does Tesorio's platform actually do?
Tesorio deploys AI agents that automate the accounts-receivable process from invoice to cash. Its Collections Agent drafts follow-up emails, extracts payment promises, and flags invoice issues. The Cash Application Agent matches incoming payments to open invoices and surfaces exceptions. A Supplier Portal Agent handles Coupa and Ariba interactions — submitting invoices, tracking payment status, and downloading remittance — without manual intervention.
Who runs Tesorio's product and engineering?
Tesorio was co-founded by Carlos Vega and Fabio Fleitas in 2015 after they completed the Y Combinator program. Both remain the firm's named leaders, though the company's website does not break out a separate CEO, CIO, or product-lead designation. The engineering team built the platform's AI promise-extraction engine, which has been in production since 2018.
Which enterprise ERPs does Tesorio integrate with?
Tesorio provides pre-built integrations for NetSuite, Sage Intacct, Workday, Zuora, Salesforce, and Stripe. For ERPs without native connectors, the firm offers Tesorio Connect, a pathway that the company says allows any ERP to link to its cash-application and collections agents.
How does Tesorio handle customer data privacy and model training?
The firm states that no customer data is used to train its AI models. Every agent operates with strict guardrails designed to prevent the fabrication of invoice amounts, PO numbers, or dates. Tesorio holds SOC 1 and SOC 2 compliance certifications and provides full audit trails for every action its AI agents take.
What results do Tesorio customers typically see?
Tesorio reports that enterprise users see an average 33-day reduction in days sales outstanding (DSO) and a 50% reduction in 90-day aged receivables. Published case studies note that GitLab saves 15 hours per collector per week, Veeva Systems cut its 90-day aged balance in half, and Smartsheet exceeded its cash goal by $14 million after deploying the platform.
Is Tesorio a venture-backed company, and what is its ownership structure?
Tesorio was founded in 2015 and graduated from Y Combinator the same year. The firm's website does not publish a full capitalization table, investor list, or current ownership breakdown. No AUM or fee structure is publicly disclosed, consistent with a private operating company rather than an asset manager.
How does Tesorio differentiate from generic AI copilots that can write collections emails?
Tesorio's agents are purpose-built for financial operations and include governance features that generic copilots lack: invoice-amount guardrails, full audit trails, and SOC 1/SOC 2 compliance. The platform also automates downstream actions — such as cash matching and portal submissions — rather than stopping at email generation, giving finance leaders a closed-loop system for the order-to-cash cycle.
