London, UK: Rillet, the agentic ERP (enterprise resource planning) platform for modern finance teams, has announced its expansion into the UK with a new office in central London and a dedicated local team already in place.
The Rillet expansion comes as UK and European customers account for 10% of the company’s net new annual recurring revenue (ARR), reflecting growing demand for its AI-powered finance platform across international markets.
The company already serves customers across the UK and Europe, including some of the fastest-growing AI companies such as Black Forest Labs, Temporal, and Primer.
With its new London office, Rillet is taking its first major step towards establishing a larger presence in Europe and building a full local team to support the region’s growing customer base.
The expansion comes less than three months after Rillet raised $100 million in a Series C funding round at a $1 billion valuation. The funding round was led by ICONIQ, with participation from Sequoia and Andreessen Horowitz.
Rillet now serves nearly 1,000 customers across 75 countries, including publicly listed enterprises and some of the fastest-growing companies globally.
Its international net new ARR more than tripled month over month, highlighting accelerating demand for the platform beyond the United States.
Rillet Expands into Europe Following Growing Demand From UK Companies
UK companies had started choosing Rillet even before the company established a local presence, prompting its decision to expand into Europe.
Europe is home to some of the world’s most ambitious companies, but many finance teams in the region continue to rely on legacy systems to close their books.
Rillet aims to address this gap by providing modern finance teams with an agentic ERP platform designed to support their evolving requirements.
Black Forest Labs, one of Rillet’s European customers, highlighted the importance of having AI integrated into the architecture of its finance technology stack.
“When I joined Black Forest Labs, I really wanted to build a finance function that embodied our company’s ambition of pushing the frontier of what was possible. We chose Rillet for our ERP because they matched that ambition.
Our tech stack needs to have AI at its core and that extends beyond features like MCP connectivity. We need AI that’s built into the architecture, with reliable data that we can both act on and interact with. Rillet provides all of this,” said Dave Arkell, CFO at Black Forest Labs.
Significant Hiring in London
Rillet is building a large-scale organisation in London, with its founding UK team already in place and significant hiring planned over the coming months.
The company has also highlighted its ability to attract talent. This month, LinkedIn named Rillet to its 2026 Top Startups list of 50 US companies.
Through its London expansion, Rillet aims to provide finance teams across the UK and Europe with a local team that is accessible, invested in their success, and committed to supporting them over the long term.
For UK and European finance leaders, the expansion comes at a time when businesses are scaling and moving upmarket. Finance teams are facing increasing pressure to improve operational efficiency, embrace AI, and build systems that can keep pace with business growth.
Rillet aims to help finance leaders navigate these challenges through its agentic platform and a dedicated team based in the region.
Bringing Close Club Community to Europe
Beyond its technology platform, Rillet is also bringing its Close Club community to Europe.
The community already connects more than 1,500 finance leaders in the US, providing a platform for CFOs to exchange ideas, share experiences, and learn from peers dealing with similar challenges.
With its European expansion, Rillet plans to extend this network to finance leaders in the region, creating opportunities for collaboration and knowledge-sharing among CFOs and other finance professionals.
“Within a year of launching in the US, we already had finance teams in the UK running on Rillet,” said Nicolas Kopp, CEO and Founder of Rillet.
“Those teams are building some of Europe’s most ambitious companies, and they deserve a finance partner that keeps up with them. Finance leaders want to know the people behind their systems are close by and committed to them, and a London team lets us be exactly that.”
Why Chose London for Its European Expansion
London is a natural starting point for the company’s expansion into Europe. The city is one of the world’s leading financial hubs, bringing together a large pool of finance and accounting professionals, an established professional services ecosystem, and some of Europe’s fastest-growing and most innovative companies.
The move also marks a return to familiar ground for Rillet CEO and Founder Nicolas Kopp, who studied accounting at the London School of Economics and spent several years working in the City.
Rillet is also looking to leverage its existing relationships with accounting firms that audit and advise some of the world’s largest companies.
Many of these firms have established operations across the UK and Europe, providing the company with an existing network as it expands its regional presence.
Its ecosystem includes an alliance with EY, a strategic alliance with RSM, and partnerships with more than half of the Accounting Today top 20 CPA firms.
These relationships are expected to provide Rillet with a foundation to establish local credibility, expand its network, and accelerate its momentum across the Europe, Middle East and Africa (EMEA) region.
With its London office, local hiring plans, growing European customer base, and existing accounting industry partnerships, Rillet is expanding its international operations to support the increasing demand for agentic ERP solutions among finance teams across the UK and Europe.
