Stacks

"Stacks felt like it was built for the way we actually want to work." - Ida Salmen, Cost Accounting Manager at @epidemicsound The full story of how their finance team rebuilt their close 👇

Great energy in the office today! ✨

A list of 37 European AI startups that raised $10M+ in Q1 2026. All likely hiring:

Shipping AI is one thing. Shipping AI that actually works in production is something else entirely. Last week, we brought together @AnthropicAI and @_StacksAI at our London office for “AI Agents in Production — Shipping AI that actually works,” a candid conversation on what it takes to bridge that gap. Adriaan Engelbrecht, Applied Engineer at Anthropic, highlighted the importance of evaluating AI models tailored to specific use cases rather than a one-size-fits-all approach. Ivan Bovyrin, Founding Engineer at Stacks, stressed that human-in-the-loop patterns are key to gathering customer feedback and improving agent performance. Both speakers emphasized that trust comes from deterministic, reliable systems. It was inspiring to be in the room alongside the engineers and builders at the forefront of Applied AI. Conversations like these continue to move the needle.

We've been running the PMM function at @_StacksAI as a team, but it needs someone to own it full-time. We're hiring our first Product Marketing Manager, positioning, launches, and competitive intel, all from scratch. Real ownership, no layers, high bar for craft. London. DM me.

Harmonic just dropped its Q2 '26 Hot 25 list, featuring the early stage companies seeing the most investor interest on @Harmonic_AI's platform. My biggest takeaways: Almost zero competition between these products. Every quarter, this list has multiple clusters of startups all sort of doing the same thing. This quarter you can argue that all of these products operate in completely different spaces / industries / core ICP. 11 of 25 were on Q1's list. This is the highest I've ever seen carry over between quarters. 23 of the top 25 have raised in the past year. On the same thread as above, investors love concentrating into the winners. Very strong technical teams. If you look at the founders backgrounds (link in next post), there's a strong bias towards very technical founding teams.

Most variance commentary stops at "what happened." The best explains why it matters, and what to do next. Christian Wattig (@Wharton FP&A) and @albertmalikov are going live April 2nd for a 60-min masterclass on AI-driven variance analysis. You'll walk away with: → The "What, Why, So What" framework → The ARCTIC method for finding the real story → How to generate variance commentary in seconds with AI Sign up link in comments 👇

Today we're launching Flux AI Agent. Flux investigates variances the way a senior analyst would. It pulls transaction-level evidence directly from your ERP, enriches it with full context, flags outliers, and writes explanations with citations back to source data. What used to take days happens in seconds.

If you're toggling back to your ERP to fix missing entries, there's a better way. Ben walks through his experience with bank reconciliations as a chartered accountant and shows how it’s supposed to be done.

oh hello there @Nasdaq tower 🗽

@SebJohnsonUK spot us when you really zoom in 👀

European tech is FINALLY firing on all cylinders. $8bn has been invested in 2026 but what stands out is the breadth of the investments. Last year it was all about the application layer. Already this year we've had big raises across: > Frontier AI - Ineffable > Chips - OLIX > Robotics - RobCo > Defence - Harmattan AI, STARK > Fintech -Pennylane, Stream > SaaS - Mews Europe needs to have players in each category and we're finally getting them There's also been a BUNCH of new unicorns and one new decacorn - ElevenLabs. The total number to beat for 2026 is $64bn (total for 2025) which I am VERY confident we will surpass. Great stuff from @yoramdw, and the @dealroomco team

Everybody has their FX rates aligned?👀

@jbahrdestefano @lightspeedvp @generalcatalyst Impossible to miss this story! ;)

Missed this fintech funding story last week! @_StacksAI raised a $23M Series A led by @lightspeedvp (less than a year after their $12M seed led by @generalcatalyst) Stacks is an agentic AI platform for enterprise accounting teams, automating reconciliations, journal entries, and the month-end close No real stats on the biz but apparently 30+ enterprise customers onboarded since coming out of stealth last year axios.com/pro/fintech-de…

@etnshow @albertmalikov @lightspeedvp Can't miss this!!

Albert Malikov (@albertmalikov) CEO and Founder of Stacks (@_StacksAI) joins us tomorrow at 2:20PM GMT after raising a $23M Series-A last week led by @lightspeedvp.

@menlotimes @eqtventures @generalcatalyst Reinventing finance as we speak!!

Stacks @_StacksAI Raises $23 Million to Reinvent Finance Operations With Agentic AI. Stacks, helping reinvent the financial close, led by Albert Malikov and the team, has raised $23M Series A led by Lightspeed, with EQT Ventures @eqtventures, General Catalyst @generalcatalyst, and S16VC doubling down. The round comes less than a year after Stacks’ $12 million seed financing led by General Catalyst, underscoring the company’s rapid traction and momentum.

The next major frontier for AI exploration might be for the Office of the CFO. This week on The Investment Memo, @_StacksAI Co-Founder and CEO @albertmalikov joins @alex_schmitti to explain the "perfect storm" hitting finance teams, from accountant shortages, fragmented data, and workflows still anchored in the past. Stacks is taking a different approach with a strong data foundation and systems designed for accuracy. It’s a clear look at how an AI-first finance stack could help set a higher bar for efficiency and accuracy. 0:00 Accounting Workflows & Quick ROI 0:49 TIM Introduction 1:42 Why the CFO Office Is Ripe for Disruption 3:41 Monthly Close & Data Fragmentation Problem 7:31 Why AI Adoption in Finance Is Hard 11:31 Stacks Origin Story & Product Vision 19:02 Real Customer Use Cases & Impact 26:22 Series A, Culture, and Future of Finance
