- Barcelona-based Factorial has closed a $150M Series D led by General Catalyst at a $2.5 billion valuation, one of the largest non-AI-infrastructure rounds in Europe so far in 2026.
- General Catalyst is simultaneously committing an additional $540M through its Customer Value Fund, a structure that ties investor returns to customer value created, not equity dilution.
- The raise opens June as one of the strongest months for European tech funding this year, following a May dominated by AI infrastructure and biotech.
Jordi Romero didn’t set out to build an AI company. He set out to fix a problem he’d already lived, the administrative chaos of managing people at a fast-growing startup. Ten years later, his company has torn up everything it built and started again.
Factorial, founded in 2016 in Barcelona by Jordi Romero (CEO),Bernat Farrero (CRO), and Pau Ramon Revilla (CTO), today announced a $150M Series D at a $2.5 billion valuation. The round was led by General Catalyst, with participation from returning investors Atomico and Four Rivers.
Three founders, one Barcelona story
The backstory matters. Romero and Ramon came from Redbooth, a project management startup that began in Barcelona before relocating to San Francisco, where both spent years building in the shadow of Silicon Valley. Farrero came from Itnig, one of Barcelona’s best-known startup studios, where he had already backed and co-founded more than a dozen companies. When Farrero convinced the other two to start Factorial in 2016, the founding team brought an unusually deep operator background to their first institutional raise and a shared conviction that European SMBs were being chronically underserved by HR software built for US enterprise.
Factorial grew without burning through capital, turned profitable before most European peers, and reached unicorn status in October 2022 on a $120M Series C led by Atomico. Most recently, in March 2025, General Catalyst committed a further $120M in non-dilutive funding through its Customer Value Fund, its first engagement with Factorial, before today’s equity stake. Total funding prior to this Series D stood at approximately $300M across all rounds. The Spanish tech now serves more than 16,000 businesses across 90 countries, employs around 2,600 people, and is hiring up to 50 new staff per week.
What it does and what it’s becoming
For most of its life, Factorial was a system of record: structured HR screens, payroll, time tracking, absence management. Its new architecture, Factorial One, rebuilds the entire product around two AI agents. One holds and applies a company’s policies across HR, finance, and IT. The other acts on behalf of individual employees: drafting work, surfacing information, executing tasks on their behalf. The bet is on deliberate simplicity: two agents with clear accountability, rather than the sprawling multi-agent deployments most enterprise vendors are currently racing to ship. As TFN has reported, European AI agent startups are increasingly chasing a $52B market but few are doing so from a base of 16,000 paying enterprise customers.
“Ten years ago we built Factorial as a SaaS company. Today we are an AI-first company, building agents for our customers,” said CEO, Romero. “This round does not close a chapter. It opens the one that matters.”
The $700M structure
Beyond the $150M equity round, General Catalyst is committing up to $540M through its Customer Value Fund, bringing total capital committed to over $700M. Under this model, GC’s returns are tied to the customer value that spend generates, not to additional equity dilution for Factorial. It’s an unusual structure that gives the company significant firepower to scale sales and marketing across Europe without burning through equity. General Catalyst, which TFN reported is in talks to raise $10B across new funds, is making its first direct equity stake in Factorial with this round.
Pranav Singhvi, Partner at General Catalyst, said, “Factorial is doing exactly that and doing it with a level of product horizontality and ambitious growth at scale that is rare anywhere in the world.” General Catalyst has previously backed Stripe, HubSpot, and Mistral.
Why this round matters for Europe
Rounds of this size don’t arrive often in European tech and when they do, they tend to cluster in AI infrastructure, defence, or biotech. Factorial’s raise is different. It is a ten-year-old workforce software company from Barcelona, built on European customers, now crossing a valuation milestone that puts it alongside Wise, Vinted, and Personio as one of the continent’s most valuable scaleups. May closed strongly for European tech – Lovable’s $330M Series B at $6.6B set the tone late last year, and 2025 marked Europe’s biggest funding year on record but June opens with Factorial’s raise as the month’s first major signal, landing in a category – enterprise software, that has historically struggled to produce European winners at this scale.
Germany is Factorial’s declared number one international growth market. A new Munich office anchors a hiring push targeting mid-market companies in a region historically dominated by SAP and Workday and one where Factorial’s compliance depth across European labour law gives it a structural edge neither US-headquartered rival has fully replicated.
Competition
Factorial’s closest European competitor is Personio, which raised $200M at an $8.5B valuation in June 2022 but has raised little since. US rival Rippling is the more formidable long-term threat, it raised $450M at a $16.8B valuation in May 2025 and has yet to crack European compliance complexity at scale. That gap is Factorial’s clearest structural advantage, and the one it is now moving aggressively to entrench.
The question Factorial now has to answer is whether two agents and a unified workspace can do what hundreds of specialised tools have failed to: make enterprise operations software something employees across 90 countries actually want to use and whether a European company, built on European discipline, can win that race before the Americans figure out how to cross the compliance moat.
