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

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:

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 !

Last night I was extremely tired and yet couldn’t fall asleep from the energy of our event, I was so stoked. Mom, I finally made it to @NYSE! Our second in person @a16z Finance Forum Demo Day event was a total blast, with 200+ CFOs and key partners joining us at the New York Stock Exchange, to watch live demos from the most innovative founders disrupting the finance categories and how the finance work gets done now with AI. Longer recap and learnings soon but just wanted to say a huge thanks to all you who joined us for the day, @seema_amble who saw the potential in the space way before anyone else did years ago, and was the great opening speaker, and the founders: - @matt_haf with @Concourse_ai - @nicckopp with @rillethq - @bensign with @joinvantage - @Riya_78 with @SequenceHQ_ - @blader with @runwayco - @nrudder_ with @get_sphere These events feel like family gatherings now. Thank you all for such a great company and here’s to many more. Where should we take our talents next?!

SF packed the house, so we’re taking it to Wall Street. Nov 11 – a16z Finance Forum: NYC Demo Day @ NYSE. AI demos from founders reinventing finance. If you’re a finance leader tired of buzzwords, this one’s for you. Sig up link below.

I’m excited to share that we’ve raised a $70M Series B, led by @a16z and @ICONIQCapital - bringing our total funding to over $100M in under a year. Accounting is a $500B category, and yet most finance teams are still running on systems built in the 90s. @RilletHQ is rebuilding the financial core of modern companies. We’ve rebuilt the general ledger from the ground up to assemble the first AI-native ERP, built for speed, flexibility, and automation. Since coming out of stealth ~12 months ago, we’ve grown lightning fast. We now power the finance stack behind companies like @PostscriptIO, @windsurf, @DecagonAI, @bitwarden and many more across many industries. Windsurf scaled revenue 10x while running global finance with just two people and Rillet. Postscript, with over $100M in ARR and four entities, now closes their books in three days. These are the kinds of results we hold ourselves to. We’ve also partnered with some of the largest and best accounting firms in the country, including @Armanino_HQ, @wissllp and Attivo. The whole industry has been begging for change for decades. With Rillet, it’s here. This round came together very quickly. The first call happened while I was eating a tuna sandwich in SF (I did not finish it). Three days later, we had a signed term sheet. It was a reflection of the momentum we’re seeing both in the product and in the market. Since announcing our Series A just weeks ago, we’ve already doubled our ARR. None of this would be possible without our team of accountants and engineers. A few months ago, I was still jumping on support calls to help customers. Today, our implementation, success, and product teams are delivering outcomes with the same speed and care that got us here. We originally booked an offsite to celebrate the Series A. In classic Rillet speed fashion, it’s now an A + B celebration. It’s proof of how fast things can move when customers love the product and a reminder of how much this team has earned the chance to celebrate together. We’re fortunate to welcome @a16z and @ICONIQCapital to the table. @arampell, @seema_amble, @mandrusko1 and @slpierre, @skstebbins bring clarity, urgency and deep conviction about the future of AI and finance. We’re also grateful to have continued support from our early partners @sequoia, @firstround, @creandum who believed in us from the start, and excited about working with @oakhcft and @FogVentures. To the Rillet team, again - thank you for building with care, focus, and speed. To our customers - thank you for pushing us, trusting us, and helping shape the product. We are honored to serve you. Let’s go!

Announcing our $25M Series A led by @sequoia Ten months ago, we came out of stealth to rebuild the general ledger from the ground up with AI at the core. Today, we power the finance stack behind some of the fastest-growing companies like @windsurf_ai and Decagon. Why are we building @RilletHQ ? Because closing the books still takes 10–20 days. Because finance teams are stuck with ERPs built a decade before the iPhone. And because every other department from sales to engineering to legal is now powered by AI. Finance should be too. Our goal is simple: zero-day close. With this fundraise, we’re one step closer. We’re incredibly proud to partner with Sequoia Capital on this next chapter. The incredible team @JulienBek @roelofbotha @Alfred_Lin and @bhalligan have already brought unmatched insights that will help accelerate our next phase of growth. They’ve seen this shift coming for a long time. Special thanks to our early investors who have doubled down in this round: @specht_p at @creandum @btrenchard at @firstround @chadbyers at @SusaVentures And to our latest angels Lee Kirkpatrick and Ron Gill, who bring with them a wealth of CFO experience and expertise having previously been at Twilio and NetSuite. Learn more about the fundraise in the blog post and media.

Huge congrats to @RilletHQ for announcing its $13.5 million seed round! Most of the complexity when it comes to high growth startup accounting is on the revenue side. Rillet integrates with your payment processor and your CRM to simplify all of this. Learn more:

Excited to back @nicckopp @RilletHQ - the next gen AI powered automated accounting / ERP. @creandum and @firstround leading a $13.5m funding. In best company w @Gloria_Bae, @scottbelsky, @cjc, @chadbyers, @kevinhartz. Our thesis here
