The CFO tech stack vertical has been one of the main beneficiaries of the investor focus on the B2B fintech post-funding boom.
Startups in the vertical are seen by investors to be more insulated from macroeconomic headwinds compared to consumer fintechs, and cater to companies with cash to spend rather than the average layperson with a limited budget.
“For a long time, VC focused on consumers and I personally wondered why,” Balderton partner Rana Yared previously told Sifted. “The spending by consumers is dwarfed by the institutional and the B2B — this is a follow-the-money story.”
Last year, CFO tech stack startups raised close to a billion euros in funding across 72 deals — and investor interest has continued this year. So far in 2025, startups in the sector have raised €115m across 12 deals.
With that in mind, Sifted spoke to investors to find out which CFO tech stack startups we should be keeping an eye on. The only catch is that they couldn’t name portfolio companies.

Stacks — Netherlands
Stacks is building AI-native financial close software designed to automate and streamline accounting workflows for mid-market companies. Financial close processes today are still highly manual and fragmented — teams rely on spreadsheets, disparate tools and email checklists to reconcile accounts, track progress and generate reports. This results in slow month-end closes, lack of visibility, audit inefficiencies and significant resource strain on finance teams.
With a large greenfield market and the rise of AI, there’s a unique opportunity to disrupt legacy incumbents and build a modern, high-performance alternative for a massive and underserved segment. Founder and CEO, Albert Malikov, is an impressive leader and product visionary.
Round — UK
Round is a modern treasury management platform built to help founders and CFOs optimise, manage and automate how startup capital is deployed across bank accounts, savings and investments. Today, most startups and scaleups manage treasury manually — spread across spreadsheets, disjointed banking portals and outdated systems, ultimately leading to poor visibility, suboptimal cash deployment and unnecessary risk exposure. As startups continue to raise large rounds and hold significant cash reserves for extended periods, there's a growing demand for smarter, more transparent treasury management. Round offers a founder-friendly, intuitive solution that brings institutional-grade treasury capabilities to startups.
Light — Denmark
Light is building a next-generation ERP system designed to automate and simplify financial operations for tech-first and multinational companies. Today’s ERP systems, built on outdated infrastructure from over two decades ago, fail to meet the needs of modern businesses — resulting in poor UX, limited scalability and costly implementations. There is strong demand from CFOs for a modular, high-performance general ledger that can adapt to their unique workflows, integrate seamlessly with modern financial tools and scale effortlessly with growing transaction volumes.

Briefcase — UK
Briefcase is on a mission to completely redefine how accounting is done by tackling the hard bits; the manual, time-consuming and often tedious tasks within bookkeeping and end-to-end management accounting. Beyond simply automating processes, Briefcase uses multimodal LLMs to contextualise transactions so the sector can move towards fully AI-native accounting. It’s starting out by solving AI-powered bookkeeping.
Mimo — UK
Mimo is simplifying how SMEs, accountants and bookkeepers manage cash flow by bringing automated accounts payable, receivable and working capital financing into one easy-to-use platform. Mimo answers one of the biggest pains for SMEs: cash flow management related to payment terms. Mimo created a slick platform and uses credit to solve both of those pain points. Using financing as a strategic entry point to unlock the market, Mimo’s approach and the benefits it brings gives it a natural path to expand into broader payment services.
Bluebook — Sweden
Bluebook wants to take the pain out of accountants’ everyday workflows. Rather than digitising tasks, it uses specialised AI assistants or co-pilots that accountants can rely on to get quick answers about regulations, accounting rules and processes, monthly reviews and more. It’s also building dedicated agents for other specific use cases, including invoice extraction, tax filings and closing checklists.

Atlar — Sweden
Atlar is positioning itself as the core infrastructure layer for CFOs, addressing the fragmentation across treasury, accounting and payments.

Solvimon is solving a major challenge in billing and monetisation, particularly for fintech and SaaS companies with complex pricing models. Founded by former Adyen leaders, the team understands the pain points of scaling revenue operations across multiple geographies and currencies. Its platform is already being used by high-growth companies like TrueLayer and Yapily, driven by their focus on making billing a competitive advantage rather than just an operational necessity.
