Rillet, a startup specializing in AI-powered accounting, announced that it had raised $100 million at a $1 billion valuation after investor discussions turned into a funding round in just 48 hours. Co-founder and CEO Nicolas Kopp said the company had not originally been seeking to raise funds, but presenting growth figures at a board meeting triggered a wave of calls and investor interest.
The round brings Rillet’s total funding since emerging from stealth two years ago to $200 million. Iconiq led the latest round, with participation from Sequoia and other investors, while Seth Pierrepont, a general partner at Iconiq, joined the company’s board. Iconiq had also co-led the previous round, while Sequoia led the Series A round.
Rapid Growth and Replacement of Legacy Systems
Rillet says its annualized revenue rate doubled during the most recent quarter alone compared with the preceding period, and that it added new customers, including several publicly listed companies. Its customer base reached approximately 600, and according to Kopp, most are moving away from legacy accounting and enterprise resource planning systems such as Oracle, NetSuite and Intuit.
The platform’s use is not limited to initial trials, according to the company. Approximately 50% of Rillet’s customers come from Intuit, 30% from NetSuite and Sage Intacct, and the remaining 20% from users of Oracle, SAP, Workday and Microsoft products. The company has also formed an alliance with EY to provide AI tools to the auditing firm.
A Platform Designed for Agents with Data Controls
Rillet was built to work with AI agents, allowing accountants to collaborate with them on bookkeeping tasks instead of carrying out every step manually. The platform includes model routing, enabling customers to choose the underlying model that processes a request, such as models from OpenAI or Anthropic. The company says its mechanisms prevent customer data from being used to train these models and do not allow training across customer data.
The agents also retain a memory of previous procedures and can use historical records to improve workflows. For approximately three months, Rillet has offered a governance feature that allows accountants to review and audit every decision made by an agent, including the figures it relied on and how they were calculated.
Why Does This News Matter?
Rillet’s round comes at a time when the United States is facing a shortage of accountants. A recent report indicated that 61% of finance leaders had difficulty finding talent in finance, accounting and certified public accounting during the past year, while the number of accounting graduates has declined since at least 2010.
At the same time, the U.S. Bureau of Labor Statistics expects accounting-related needs to grow by at least 5% and add 72,800 jobs by 2034. The bureau does not expect AI to reduce demand for accountants; rather, it believes that automating tasks such as data entry could give them more time for advisory and analytical work.
Transactions conducted by AI agents at public companies are currently subject to additional human review and approval, making tracking and auditing tools an essential part of deploying these systems. Kopp says Rillet is not targeting the replacement of accountants, including junior ones, but aims to assist them with routine work and enable them to focus on financial decisions.
