Hyphenate raises $45M Series A to expand autonomous finance agents

B Capital participated, along with existing backers Foundation Capital, BoldCap and Gaia Ventures. The round brings Hyphenate's total funding to $54 million. The company, officially Prosperous Commerce Inc., was known as Maximor until it rebranded earlier this month.

Hyphenate's platform uses self-learning AI agents that integrate with a company's existing enterprise resource planning, accounting and banking systems. The agents are designed to perform tasks such as general ledger accounting, treasury management, order-to-cash, procure-to-pay and financial reporting, without requiring customers to replace core software.

The company is trying to address CFO concerns about AI errors. In a recent study cited by Hyphenate, 96% of survey respondents said alleviating repetitive and manual tasks was a major benefit of AI, but only 14% said they trusted the technology to do that work without mistakes. 97% said human supervision of AI work is essential. CEO Ramnandan Krishnamurthy acknowledged that regulatory requirements and financial reporting standards have made CFOs reluctant to tolerate agents that might hallucinate and disrupt calculations.

Instead of asking financial experts to write prompts or design rule-based workflows, Hyphenate trains agents on a customer's historical financial workflows. The agents examine years of spreadsheets, email trails, financial records and invoices to capture what Krishnamurthy calls the "tribal knowledge" of a finance department. The company also records each autonomous action to create an auditable paper trail. When a human financial officer handles an exception, the agents store that decision as a precedent for future work. Hyphenate says the system operates under explicit guardrails and requires human oversight at key moments that need qualitative judgment.

"Every finance team has a long list of work it does because somebody has to do it," Krishnamurthy said. "Our customers are watching that list shrink in production. Once a team sees the system handle one workflow to an auditor's standard, they hand it the next one."

Hyphenate says customers typically test agents on one or two financial tasks, then expand responsibilities after the system performs to standard. The startup says its customer base grew 11 times and revenue grew 86 times in the past year, without providing more specifics. It counts six publicly traded companies as customers, including Groupon Inc., Synthesia Ltd., HiBid and Mini Melts USA Inc. Those clients have eliminated up to 90% of routine manual financial work and reduced audit exceptions by an average of 75%, according to the company.

HiBid has used Hyphenate to process more than $2.5 billion in gross merchandise value and cut its month-end closing time from three weeks to one day, according to the company. Nexus Venture Partners' Abhishek Sharma said Hyphenate's progress stems from focus on accuracy, controls and auditability. "Hyphenate has built around that bar from the beginning and the expansion we are seeing inside customer deployments shows what becomes possible once the system earns the right to take on more work," he said.

With the funding, Hyphenate says it aims to automate strategic financial operations for customers, expanding beyond routine finance tasks.
