Two pre-seed rounds announced this week, one in Stockholm and one in Amsterdam, together total less than €4 million. In a quarter where biotech and data-centre infrastructure are drawing nine-figure cheques, that sum barely registers. Yet the two deals tell a more revealing story about where enterprise software is heading than most of the larger headlines. Both Vessla and Huppa describe themselves not as tools or platforms but as "operating systems" for a specific industry. Both have been backed by operators from the previous generation of European software winners. And at least one of them, Vessla, is explicitly built around AI agents rather than human users clicking through screens. Taken together, they mark a shift in how the next cohort of enterprise SaaS companies is being conceived, funded and positioned. The deals in detail According to EU-Startups, Vessla has emerged from stealth with €2.94 million (roughly $3.3 million) in pre-seed funding to build what it calls an agentic operating system for real estate. The round was more than twice oversubscribed and was led by Seedcamp, with participation from Inception Fund, Tiny VC and operators from Lovable and OpenAI. The investor roster is worth pausing on. Lovable is the Stockholm company that has become one of Europe's most visible AI-native success stories; OpenAI needs no introduction. That individuals from both are writing angel cheques into a property-management startup suggests the people closest to frontier AI see vertical, workflow-heavy industries as the natural first landing zone for agents. Huppa, meanwhile, has raised €1 million in pre-seed funding for an all-in-one platform serving gyms, CrossFit boxes and fitness studios, EU-Startups reports. The round was led by a group of entrepreneurs including the founders of Sentia, Keylane, TicketSwap, Moneybird and Revue, five Dutch companies spanning cloud infrastructure, insurance software, ticketing, accounting software and newsletters. That is a notably experienced bench for a sub-€1.5 million round in a sector that most venture investors would once have dismissed as too small and too fragmented. Why vertical, and why now The enterprise SaaS playbook of the 2010s favoured horizontal products: one CRM for everyone, one HR system for everyone, one collaboration tool for everyone. The logic was that total addressable market scaled with generality. The weakness was that general tools rarely fit any single industry well, which is why mid-market businesses in property, fitness, hospitality and logistics ended up running their operations on a patchwork of spreadsheets, legacy point solutions and WhatsApp groups. Vertical SaaS reverses the trade-off. By narrowing the customer to a single industry, a company can absorb the entire workflow, from scheduling and billing to compliance and communication, and in doing so capture a far larger share of each customer's software and payments spend. The "operating system" framing used by both Vessla and Huppa is a signal of that ambition. Neither wants to be one line item among many; each wants to be the layer everything else runs on. What has changed in the past eighteen months is that AI has made this ambition more credible. Property management and gym operations are both heavy with repetitive, text-based, judgement-light tasks: tenant queries, maintenance triage, lease renewals, class waitlists, membership churn follow-ups. These are precisely the tasks where language-model agents have moved from demo to deployment. Vessla's decision to describe itself as agentic rather than merely AI-enabled is a bet that the winning product in property management will not be a better dashboard but a system that does the work with minimal human prompting. The European angle For the European ecosystem, these rounds matter for three reasons. First, they demonstrate a maturing recycling of capital and expertise. Huppa's cap table is essentially a who's who of Dutch software founders from the previous cycle. Vessla's includes operators from Lovable, a company that is itself less than three years old. The speed at which successful European operators are turning around to fund the next generation is accelerating, and that compounding effect has historically been the hardest thing for a startup ecosystem to manufacture. Second, they show that Europe's strength in vertical, unglamorous B2B software remains intact even as the spotlight falls on foundation models. Europe has never produced an OpenAI, but it has produced a long list of durable vertical software businesses. The combination of deep domain focus with imported AI capability is a plausible path to building companies that are globally competitive without needing to win the model race. Third, the modest size of these rounds is itself informative. Seedcamp leading a €2.94 million round that was twice oversubscribed implies the founders could have raised more and chose n
