Ever since I met @sidd in our early days at Stripe, I hoped we’d one day find an idea big enough to start a company together.
That day is finally here.
After building quietly for the past year, I’m excited to officially launch @AccrualHQ, a new foundation for professional accounting 👇

More on Arc in @AccountingToday
"Arc extends Accrual's platform across tax, audit, client accounting services and advisory. It works alongside Accrual's other dedicated workflow products to handle investigations, analyses and other assignments that span systems. Permissions, recorded actions and human review are built into the process; practitioners retain responsibility for final judgment and approval."

We built “ARC” internally for Accrual earlier this year. Every candidate and new hire raved about what it’s capable of, across the board. Inevitably someone asked the obvious question: why wouldn’t we give this to our customers, purposefully built for firms?
Seeing accountants use Arc in the few weeks brought a sense of excitement and joy similarly to early prototypes of Accrual. We can’t wait to see how you put it to work, in ways we haven’t even thought of.
Enjoy!
Every accounting firm has work that has no screen.
The investigation that crosses three systems. The client question that requires digging through old correspondence. The analysis someone assembles by hand because no workflow was ever built for it.
Meet Arc.
Give Arc a substantive job. It gathers the context, develops a plan for approval, does the work, and brings back finished work for review.
We built Arc first to run Accrual. Now we’re bringing it to accounting firms.

We started Accrual in tax. We always believed that was the beginning.
Today, we’re expanding across tax, audit, and advisory, with one intelligence platform built for the way accounting firms work.
We’ve been building for where the profession is going.

This is the way. Accept code on merit and ensure that a person takes accountability for it. Doesn’t matter if it was typed, chiseled, generated, or bit-flipped via magnetized needle on a chip.
If it’s good, it’s good. If it’s slop, it’s slop.
KDE is working on an official AI / LLM policy, and it reads like the rules of Fight Club.
In short, KDE’s AI policy:
1) Encourages using AI, as long as a human is kept “in the loop”.
2) But you can’t tell anyone that you used AI.
“Don’t disclose LLM usage”.
“Don’t add ‘Assisted-by: [some LLM]” (as is done in the Linux kernel).
“Nobody in KDE should know if you use an LLM”.
In other words: “Welcome to developing KDE with AI. The first rule of developing KDE with AI is: you do not talk about developing KDE with AI.”

2) is precisely how I feel on a daily basis
Two things early founders often get wrong, and should remember:
1) Building culture can feel like it's just fluff at the start. Until you start to raise capital or hire teams, and then you see how it shapes everything you do moving forward.
2) You should build a team so talented that it makes you slightly uncomfortable to be with them, because you know you are going to have to raise your game to keep up.

As great as Sam is at hyping, Monaco exceeds it 🔥
Today, we're launching Monaco into General Availability.
We onboarded several hundred hypergrowth startups during our beta. The results are staggering:
The average customer added 16 percentage points to their month-over-month revenue growth rate.
The average customer tripled their monthly meeting volume.
With today's release, Monaco is now the most advanced AI sales platform in the world.
Monaco customers have an unfair competitive advantage.

Europe in summer isn’t exactly famous for productivity. We did our part, for one week, at least
Every few months at Accrual, we close Slack, pack up our laptops, and meet somewhere new for hackweek.
This time: France, famously the place to go in summer when you really want to get some work done. 🇫🇷
Being remote-first doesn’t mean we don’t spend meaningful time together. Quite the opposite: we’re very intentional about it, and about making that time count.
Hackweek starts with our customers: the conversations we’ve had, the pain points we keep hearing about, and the ideas we can’t stop thinking about.
Then everyone jumps in.
Engineering, product, and design, but also sales, operations, and recruiting. During hackweek, customer feedback is every Accruer’s job. We question assumptions, debate ideas, make decisions, build, break things, fix them, and ship – a LOT.
And the best parts of hackweek rarely make it into the demo.
They’re the long dinners, wrong turns through a new city, running jokes that follow us home, and discovering that the person you’ve been slacking with in recent weeks is, in fact, a really lovely human.

Working at the edge of AI-native means we're not just building AI for our clients. We're building it for our team.
Meet Arc: the Accrual Remote Coder. An agent platform we built ourselves, for ourselves.
CPAs propose changes to the tax logic they review. Account managers show up to calls already briefed. Support ships its own fixes. Titles stop mattering when the tooling removes the boundary between them.
Our teammate Jarrod wrote about what that looks like from the inside - this is the first of two posts on Arc.

Accrual has converted 100% of our pilots to production with the biggest accounting firms in the country. @getCos chatted with @pablosrugo on the latest episode of The Product Market Fit Show to share more about Accrual's growth.
From Cos: "Most AI tools in accounting quietly patch over failures. Humans fixing what the model got wrong before you see it. Running the same return multiple times and handing you the best version. We don't do that. We show firms exactly what the AI produces, return by return, side by side with what they finalized. Where we're wrong, we say why."

"Writing code is one of the most satisfactory things in my life. Almost every day, if I had a choice, I would end up writing code," - @getCos, Co-Founder and CEO of Accrual.
Our team isn't all engineers, but we're bringing an engineering mindset to everything we do at Accrual: never stop building, improving, and delivering.
Many thanks to @_uncoveredmedia for capturing what we're all about.

Demos are easy. Production is hard.
This season Accrual helped CPAs prepare nearly 20,000 complex tax returns.
You don't get there with a wrapper.
Sat down with @marcbhargava from @generalcatalyst on what AI-native actually means for accounting.

Firm Growth Forum with @AccountingToday is a wrap! It was great to see so many clients, advisors, and industry leaders all in one place this week in sunny San Diego. Very proud of the way Accrual showed up - from panel discussions, to onstage case studies with @Armanino_HQ, to dinners and nonstop conversations.
The through line was clear: firms are moving past the question of whether AI will matter in accounting. They are focused on how to pilot it, evaluate quality, build trust with reviewers, and move from a controlled test to a firm-wide rollout.

First tax season at scale == tons of learnings 🤓
Tax Season 2026 in review: what we learned.
Over the last month, we compared Accrual drafts against filed returns, including the corrections we caught during tax season and the ones preparers and reviewers made later in the tax engine.
We distilled exactly how 1040s moved from Accrual draft to firm-finalized return and we're already working on improvements.

🧵@AccrualHQ is building the platform accounting firms can run their AI transformation on.
That's why @Armanino_HQ has been such a strong partner. As part of their Vision 2030, they set out to rethink how tax work gets done, and brought AI into production this season across six offices.

What that looked like in practice:
• 15 min median time to draft a return
• 3 existing tools replaced with Accrual
• 74% client portal acceptance (industry: 10 to 40%)
• Up to 60% fewer prep hours on complex returns
• Reviewers shifted from field-by-field verification to judgment and client work

The most ambitious firms aren't buying point solutions. They're rebuilding how the work gets done.
82% of Armanino users plan to expand next season. Grateful to Cody, Tim Webb, Chris Carlberg, and the entire Armanino team.
