Rillet has landed in the UK! Today we’re opening our London office as we expand into Europe. This comes at an exciting moment for us. Although we've had customers in the EU since the early days of @RilletHQ, we're accelerating dramatically. 20% of our customers today already operate in the UK and Europe and we are excited to support them locally now, as well as expand our support to more companies across the pond. This moment also feels like a full circle for me personally. After having spent years studying and working in London, I’m excited to reconnect with old friends and colleagues in the City. If you're local and unreasonably passionate about what we're building, we're hiring in person!

At @RilletHQ , we obsess over outcomes. Sure, an agent can pull a report or run the numbers for an ad-hoc analysis. But the more tedious work for finance teams is acting across systems like Salesforce, Slack and Gmail: chasing overdue invoices, sending collection emails, booking a bad-debt reserve. That’s the work Rillet’s agent harness automates.

Legacy ERPs were designed as systems of record. The newest AI products repeat the same mistake: agents layered on top of systems that were never built for them, working from thin data, with a human directing every step. We built Rillet differently from the foundation up. Every business event becomes a purpose-built economic primitive, carrying the full context of what happened and why, with a set accounting result that doesn’t need an LLM to decide. And on top is the harness. — Ingests context across your stack — Routes tasks to the right model — Handles multi-step workflows — Human approval where it matters. One environment where humans and agents share the same financial truth, divide the work, and keep every action auditable. In 2-3 years, we believe every company will run finance this way. That's the accounting superintelligence we're building at @RilletHQ .

.@roelofbotha, who was CFO for PayPal through its IPO and sale to eBay, on why he's betting on the AI start-up @Rillet: "ERP is one of the most important categories of software — changing your ERP or accounting system is like open heart surgery." cnb.cx/4x5WO8B

The U.S. has a shortage of accountants right now, which is driving growth of Rillet CEO Nicolas Kopp's AI-native accounting platform so much, he raised $100M in 48 hours. spr.ly/6011B1WU19

Last night we announced our $100m fundraise at $1B led by @ICONIQCapital. The response has been tremendous. We're creating an entirely new category of finance. Right now this seems ambitious but five years from now, what we're doing will seem obvious. The future runs on @RilletHQ. Let's go

A year after partnering with @RilletHQ on their Series B, we're honored to deepen our partnership with @nicckopp and the team by leading their Series C. Over the past 12 months, Rillet has grown to serve more than 600 companies across 60 countries, is winning head-to-head evaluations against legacy incumbents, expanded Aura AI into a platform of purpose-built agents across the accounting cycle, and built a partner ecosystem spanning EY, KPMG, and half of the top 30 U.S. accounting firms. The clearest sign of progress to us comes from customers closing their books in hours and pushing toward a zero-day close. Nic and the team are bringing reliable, real-time financials within reach for modern finance teams, and we're honored to be by their side for the journey.

When we started researching @Rillet, we reached out across the Bain Capital portfolio to make CFO intros. Turns out, many didn’t need one. They were already customers. That kind of pull is notable in ERP, a category built around systems that are notoriously hard to rip out. Rillet is building accounting superintelligence: a real-time ledger with deep context and agents that tackle increasingly complex financial work. We’re excited to participate in Rillet’s $100M Series C as @nicckopp and team take on some of the most entrenched players in enterprise software! cc @Abby__Meyers Josh Xu @BainCapVC fortune.com/2026/08/18/rille…

Today we're announcing our $100M Series C at a $1B valuation, led by @ICONIQCapital. It's our third round in 14 months and brings our total funding to over $200m The round came together in less than 48 hours. We weren't planning to raise. Then new ARR doubled last quarter and we crossed 600+ customers including public companies and enterprises with $2B in revenue. Rillet AI agent usage is growing 70% each month and CFOs are replacing Oracle Fusion, SAP and Workday to run their companies on Rillet. We also announced our alliance with EY and officially partnered with more than half of the top 20 CPA firms. @RilletHQ is creating an entirely new category of finance infrastructure. With Rillet, the ERP becomes the harness for the modern finance organization, where people and agents share the same financial data, apply the same accounting policies and controls, and work from a single, continuously updated view of the business. Agents perform increasingly complex financial work, while finance teams retain visibility, approval authority and a complete audit trail. Thank you to our customers for believing in the mission and building the future of finance with us. We could not do this without you. Thank you to the Rillet team. As I say often, building Rillet is our own version of sending rockets to Mars. It is incredibly difficult. You make it look easy. Finally, thank you to our investors. To ICONIQ for leading the round and to our existing and new investors for building with us. @sequoia , @a16z, Sequoia Global Equities, @BainCapVC, @oakhcft, @BatteryVentures, @FirstMarkCap, @scalevp, and @creandum. Back to work :)

We built Rillet on the idea that the centuries-old practice of "closing your books" should be obsolete. Month-end, which used to be a scramble to reconcile everything and get the numbers to zero out, is now just another day. Based on a sample of Rillet customers, we went deep with @a16z on how AI-native ERP is breaking the mold of traditional accounting.

For the last 20 years, sales leaders insisted on Salesforce. Same with NetSuite and finance. A terrible UI was not a dealbreaker since it's what they knew and trusted. Less than 6 months of being Claude-pilled and those same people are building w/AI and open to new tools. The mindset shift is real. Let's go @RilletHQ 😀

The finance role is evolving. FP&A is moving to real time reporting. Accountants are becoming orchestrators of data and systems. Historically, much of our time has been spent sorting, copying, pasting, filtering - the classic “why don’t these two data sets match?” AI-native teams are operating differently. They’re building data cleanliness with Rillet upstream so everything is queryable downstream in a secure and compliant manner. We are building the next shift in AI that doesn't wait to be asked. No prompts or queries needed. It surfaces the anomaly before anyone knew to look for it - continuously in real time, running in the background. So your team focuses on the work that actually moves the business forward. Yesterday I sat down with Romaine Bostick and Katie Greifeld at Bloomberg to talk about exactly this. We got into why human-in-the-loop still matters even as automation accelerates and what @arampell means when he says the best companies are filing cabinets. Thank you for having @RilletHQ and @a16z on air! Watch the full interview here: bloomberg.com/news/videos/20…

My face was on macarons last night. Career highlight honestly. I did a fireside chat with @a16z, @Stifel & @RilletHQ about how elite sport & startups have a lot in common: risk, unglamorous work, betting on yourself, and defying the odds. Feels like I never left Silicon Valley after all. Thanks @tesshatch @nicckopp @IvanoMakSF !
