The short version

Rillet has opened a new office in central London to serve fast‑growing UK finance teams. European customers already account for about 10 % of its latest recurring revenue and the firm plans large hires in the city.

What happened

Rillet, a US‑based “agentic” ERP (enterprise resource planning) platform that combines a real‑time ledger with built‑in AI agents, announced a new office in central London.

The company says finance teams in the UK and Europe already generate 10 % of its net new annual recurring revenue (ARR).

It now serves close to 1,000 customers across 75 nations and is expanding a large‑scale operation in London, building on a founding UK team and planning major hiring in the next few months.

Within a year of launching in the US, we already had finance teams in the UK running on Rillet.

The background

According to the source, the worldwide ERP market amounted to $60 billion in 2024 and is projected to grow to $119 billion by 2030, with cloud‑based solutions accounting for 65 % of revenue.

Finance teams still need an average of 6.2 business days each month to close their books, a process that AI‑enabled ERP systems aim to accelerate.

Rillet’s “agentic” approach embeds AI agents directly into the ledger, avoiding the data‑quality problems of bolt‑on tools and promising faster, continuous closes.

What it means for owners and operators

Owners can expect a finance system that reduces month‑end workload, freeing staff to focus on analysis rather than manual entry.

Operators will have local support in London, meaning faster issue resolution and easier integration with UK‑based accounting firms such as EY and RSM.

Executives gain access to real‑time financial data, which can improve cash‑flow visibility and support faster decision‑making as the business scales.

Founders of fast‑growing firms may find the agentic ERP a more scalable alternative to legacy systems that often require costly customisations.

The numbers

10 % of Rillet’s net new ARR now comes from the UK and Europe.

The company serves nearly 1,000 customers across 75 countries.

The company’s international net new ARR increased by more than three times each month.

Rillet secured a $100 million Series C round at a $1 billion valuation and its total financing now exceeds $200 million.

Our take

Analysis by Infercline · Scale it down

A London hub lets a US ERP platform lock in fast‑growing UK finance teams before competitors.

What to do in your business tomorrow

  1. Review your current ERP’s month‑end close time and benchmark it against the 6.2‑day average.
  2. Map the finance functions that could be automated with AI agents and evaluate if a modern ERP could reduce headcount pressures.
  3. Assess the availability of local finance talent and support partners to ensure you can maintain compliance while adopting a new system.
