The accounting platform that started as a Google Sheets add-on and grew up to close the books - automatically, in real time, across 160+ currencies.
There is a particular kind of dread that finance teams know well. It arrives around the fifth of the month, when last month's numbers are still not closed, when someone is pasting a trial balance into a spreadsheet for the third time, and when the board deck is due tomorrow. LiveFlow is a company built almost entirely around removing that dread, which is a less glamorous mission than curing cancer or reaching Mars, but a considerably more addressable one.
The premise is simple enough to fit on an index card. Accounting data lives in systems like QuickBooks Online and Xero. Analysis and reporting happen in Google Sheets and Excel. Between those two worlds sits an enormous amount of manual copying, pasting, reconciling, and swearing. LiveFlow's original product was a pipe between them - connect your accounting system, and your spreadsheets fill with live numbers that update on their own. No export. No stale figures. No 11pm discovery that the version you sent the board was wrong.
That is not a revolutionary idea, and LiveFlow would probably be the first to admit it. What is interesting is who built it and how far they took it. The three co-founders - Lasse Kalkar, Anita Koimur, and Evan O'Brien - all previously worked at Revolut, the fintech that is famous, among other things, for moving very fast and expecting its finance function to keep up. If you have spent time closing books inside a hyper-growth fintech, you have a fairly vivid understanding of why the existing tools are inadequate. LiveFlow is, in a sense, the product those three wished they had.
"Finance teams are being asked to move faster and play a more strategic role, but the tools they've been given haven't kept pace."
Lasse Kalkar, CEO & Co-founderThe company went through Y Combinator and raised a $3.5 million seed round in 2021, led by Moonfire Ventures, with Y Combinator, Seedcamp, and WndrCo along for the ride. The angel list is the kind that makes other founders slightly jealous: Klarna co-founder Victor Jacobsson, a Google VP of product, and a former Airbnb international-expansion executive among them. In September 2024, Valar Ventures led a $13.5 million Series A, which brings the total raised to roughly $20.9 million - not a staggering number by fintech standards, which is arguably the point. This is a company selling something people actually pay for, not a moonshot burning capital to manufacture demand.
You can learn a lot about a B2B company from the shape of its customer list, and LiveFlow's is instructive. Brands like Wendy's and Crumbl Cookies use it. Accounting firms like BDO and KLR use it. What those have in common is not size but structure - lots of entities, lots of locations, lots of intercompany transactions that have to be netted out before anyone can see a clean number. This is precisely the situation where consolidation stops being tedious and becomes genuinely hard.
LiveFlow likes to tell a story about one of its Crumbl Cookies customers, who was booking multiple intercompany journal entries for what was, conceptually, a single event. With LiveFlow, that collapsed into one entry. It is the sort of detail that sounds trivial until you multiply it across dozens of franchise entities and a monthly cadence, at which point it becomes the difference between a finance team that goes home at six and one that does not.
"Flow is built for continuous close - where accounting, consolidation, and planning work together in real time."
Lasse Kalkar, on LiveFlow's AI-native ERPThe most recent chapter, and the most ambitious, is Flow - an AI-native ERP that LiveFlow introduced in February 2026. This is a meaningful escalation. A reporting layer that sits politely on top of your accounting system is one thing; an ERP that aspires to be the accounting system is another. The pitch is "continuous close," the idea that the month-end close should not be a discrete, panic-inducing event but a background process that is always mostly done. Flow orchestrates what LiveFlow describes as a team of AI agents to handle reconciliations, categorization, and intercompany elimination on an ongoing basis.
There is a slightly counterintuitive strategy underneath all of this. The conventional wisdom in enterprise software is that ERPs are sticky because they are painful to replace, and that the way to win is to convince a customer to endure the pain of migration. LiveFlow did the opposite. It started by meeting finance teams inside the spreadsheet they already lived in, earned trust by getting the numbers right, and only then earned the right to move toward the core. Migration to Flow, the company claims, can happen in under a day - which is a promise that only makes sense if you have already spent years proving you will not break anything.
The other notable thing about LiveFlow is what it says it is not trying to do. In an era where every finance-automation pitch seems to end with the quiet implication that accountants are a cost to be eliminated, LiveFlow has been unusually explicit about the reverse. Its stated ambition is to make accounting appealing to new graduates by automating the tedium so the humans can do the judgment. Whether that is genuine conviction or clever positioning is hard to say from the outside, and it is probably a bit of both. Either way, it is a more interesting bet than "software replaces people," and it happens to align with the interests of the accounting firms LiveFlow sells to.
None of this guarantees the outcome. Moving upmarket into ERP territory means bumping into NetSuite and Sage Intacct, incumbents with decades of entrenchment and enormous switching costs. And "AI agents that close your books" is exactly the sort of claim that sounds wonderful until an agent quietly miscategorizes something and no one notices until the auditors do. But LiveFlow has the two things that matter most at this stage: real customers paying real money for a problem they genuinely hate, and a founding team that has felt that problem personally. In accounting software, that is often enough to build something durable.
