At F-Prime, we have long tracked the transformation of the CFO stack as one of the biggest opportunities in fintech today, an active space with plenty of greenfield. In our 2026 State of Fintech report we observed that AI adoption has lagged across financial services — but with the rapid pace of technological advancement, we expect that to change quickly.

Accounts receivable (AR) is especially overdue for AI-driven transformation: the workflows responsible for collecting revenue remain stubbornly manual, relying on spreadsheets, back-and-forth emails, and human judgment to match payments, chase collections, and reconcile mismatches. There are nearly 1.6M accounts receivable clerks in the US today, earning a median salary of $47K and representing a $76B labor market — a testament to this function’s labor-intensivity. The problem is especially acute for businesses in traditional industries like staffing, professional services, and wholesale, where cash flow makes the difference between making and missing payroll.

The first wave of AR software relied on rigid, rule-based systems that only achieved around 40% automation. These systems broke down on exceptions and required enough manual intervention to limit overall adoption. Given the choice, businesses typically chose to solve the problem through labor alone.

But rapid advancements in LLM and agent capabilities now make it possible to automate the messy, judgment-intensive exceptions that broke historic rules-based automation. For the first time, a truly AI-native AR platform can serve the businesses that need it most.

We first met Caitlin and Timmy in September 2024, when they were going through Y Combinator. We fell in love with the team immediately; Caitlin’s sharpness and drive were obvious from the first conversation, and Timmy’s technical depth and customer empathy left a lasting impression on everyone who met him. Having experienced the pain of broken AR workflows firsthand when building their last company, they set out to build the platform they wished they had.

The result is Fazeshift: an AI-native AR automation platform that replaces manual invoice-to-cash workflows with autonomous agents, purpose-built for traditional industries with deep integrations spanning staffing, professional services, wholesale, construction and beyond. Over the past year we stayed close, watched them execute against major milestones, and heard glowing feedback from customers who described Fazeshift as transformative for how they ran their financial operations.

Across our global platform, we are proud to have backed foundational companies that are innovating in the CFO Suite, such as Toast, Flywire, Spendesk, and Icertis. Today, we are thrilled to announce that we are leading Fazeshift’s $17M Series A, bringing total amount raised to $22M. Congratulations to Caitlin, Timmy, and the entire Fazeshift team on this milestone — we could not be more excited to partner with you as you transform financial workflows and bring us closer to an autonomous finance future.
