San Francisco-based Fazeshift, an artificial intelligence platform focused on automating financial operations, has received backing from Amex Ventures, the corporate venture capital unit of American Express (NYSE: AXP). The investment, announced on August 11, 2026, will help the company broaden its technology beyond its core accounts receivable focus and accelerate development toward a more comprehensive autonomous finance solution for enterprise teams.
Fazeshift specializes in deploying autonomous AI agents that handle complete accounts receivable processes.
These include generating invoices, reconciling payments, managing collections, and coordinating communications across the existing software tools that finance departments already rely on, such as enterprise resource planning systems, customer relationship management platforms, email, and payment systems.
Rather than simply flagging issues or offering suggestions, the agents carry out the work end-to-end, aiming to free staff from repetitive manual tasks that often slow cash collection and create operational bottlenecks.
The new capital from Amex Ventures builds directly on Fazeshift’s earlier Series A round.
That financing, completed in May 2026 and led by F-Prime with participation from Gradient, Y Combinator, Wayfinder, Pioneer Fund, Ritual Capital, and others, raised $17 million and brought the company’s cumulative funding to $22 million.
The latest investment is earmarked for product enhancements and team expansion as Fazeshift works to evolve its offering into what it describes as a full “CFO suite built for autonomous finance.”
“This investment lets us move faster on our mission of giving finance teams their time back,” said Caitlin Leksana, CEO and co-founder of Fazeshift.
Margaret Lim, managing director at Amex Ventures, noted:
“We are excited to be backing Fazeshift as they continue to assemble a strong team and build out an expanding suite of agentic capabilities to modernize finance operations.”
Accounts receivable has long remained one of the more labor-intensive areas in corporate finance, frequently involving spreadsheets, fragmented email chains, and disconnected systems that delay payments and consume significant staff hours.
Fazeshift positions its AI agents as a way to address these inefficiencies at scale, improving cash flow, lowering overhead, and allowing finance professionals to focus on higher-value analysis and strategy.
Prior to the Amex investment, the company reported strong traction, including rapid revenue growth and adoption by a range of enterprise clients.
By securing support from one of the world’s leading financial institutions, Fazeshift gains not only capital but also potential alignment with broader trends in business-to-business payments and the growing role of agentic AI in transforming how money moves through organizations.
The partnership signals confidence that AI-native tools can meaningfully modernize core finance functions.
As Fazeshift deploys the new resources, the company aims to extend its agent platform into additional areas of finance operations while continuing to refine its accounts receivable capabilities. The backing from Amex Ventures underscores ongoing investor interest in solutions that reduce manual workload and introduce greater autonomy into enterprise financial workflows.
