Rillet, a startup specializing in AI-powered accounting software, has raised $70 million in a Series B funding round co-led by venture capital giants Andreessen Horowitz and ICONIQ [1]. The funding brings the company's total capital to over $100 million, following a $25 million Series A round just two months earlier [2].

The funding will be used to accelerate the development of Rillet's AI-native ERP solution and expand its team, with a particular focus on hiring more engineers. The company aims to disrupt the traditional accounting industry dominated by legacy players like Oracle and Microsoft [3].

Rillet's platform automates routine accounting tasks, enabling finance teams to close their books in hours rather than weeks. It integrates seamlessly with systems such as Salesforce, Stripe, and Brex, providing real-time insights and replacing outdated systems that function merely as "dumb databases" [1, 3].

The company has already demonstrated rapid growth, with over 200 enterprise clients since its launch in 2024 and a doubling of its annual recurring revenue in the past 12 weeks [2, 3]. Strategic partnerships with major accounting firms, including Armanino and Wiss, further underscore its expanding influence in the finance sector [2, 3].

As part of the funding deal, Andreessen Horowitz's Alex Rampell and ICONIQ's Seth Pierrepont will join the company's board of directors. Their involvement underscores the strategic importance of Rillet in the AI and SaaS ecosystem and aligns with broader industry trends toward AI-enhanced enterprise software [2, 3].

The Series B round reflects a larger shift in financial infrastructure, where AI is increasingly viewed as a core component of modern business operations [3]. Rillet's focus on automation and AI positions it as a key player in a rapidly evolving market. As enterprise finance systems continue to digitize, Rillet's approach could signal a long-term transformation in how companies manage their financial data [3].
