Rillet, an agentic ERP (enterprise resource planning) platform for finance teams, has announced its expansion into the UK with a new office in central London.
The San Francisco company said its UK team is already on the ground.
Rillet said customers in the UK and across Europe already drive 10% of its net new ARR.
Those customers include Black Forest Labs, Temporal and Primer, which Rillet describes as some of the fastest-growing AI companies.
The company said its international net new ARR more than tripled month over month.
Rillet said UK companies were choosing it long before it had a local presence, which drove its decision to expand into Europe.
The expansion comes less than three months after Rillet raised a $100 million Series C at a $1 billion valuation, led by ICONIQ with participation from Sequoia and Andreessen Horowitz.
Rillet said it now serves nearly 1,000 customers across 75 countries.
It said it is building a large-scale organisation in London, with its founding UK team in place and significant hiring planned in the months ahead.
Nicolas Kopp, CEO and founder of Rillet, said: “Within a year of launching in the US, we already had finance teams in the UK running on Rillet.”
He added: “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.”
Dave Arkell, CFO at Black Forest Labs, said: “We chose Rillet for our ERP because they matched that ambition.”
Rillet said London is a natural starting point because the city brings together a deep pool of finance and accounting talent and an established professional services ecosystem.
The company said the move is also a return to familiar ground for Kopp, who studied accounting at the London School of Economics and spent several years working in the City.
Rillet is also bringing its Close Club community to Europe, which it said already connects over 1,500 finance leaders in the US.
The company said 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.
Rillet said those relationships give it a foundation to build local credibility and accelerate momentum across EMEA.
