"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 👇

Reassigning checklist tasks one by one is the kind of small friction that quietly slows down a close. People go on leave, ownership shifts, due dates move. Bulk actions fix that. Select the tasks, an action bar appears at the bottom of the screen, reassign preparer or reviewer, shift due dates, or delete in one go. Conflicts stay surfaced so nothing slips.

We just shipped the biggest Flux update since launch. Until today, Flux only did MoM variance. It now runs four comparison modes, with AI explanations across all of them: → Monthly → Quarterly (any 3-month block) → Yearly (any 12-month block) → Custom (incl. fiscal YTD) Use flux analysis for board decks, auditors, group reporting and more: all in one tool.

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.

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.

People of technology.

Everybody has their FX rates aligned?👀

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

Stacks has been freeing up 100,000 hours for accountants across dozens of organisations. @alex_schmitti from @lightspeedvp & @albertmalikov sit together to discuss the drastic changes in the finance landscape.

@_StacksAI has raised a $23M Series A, led by @Lightspeed, with @EQTVentures, @GeneralCatalyst, and @S16VC. Less than a year out of stealth. Here's what's happened since 🧵
