Tax compliance is becoming more and more complicated. Multinational firms now have to deal with a variety of reporting requirements across multiple countries, and doing so by hand is unsustainable. A-Cube is an Italian API-first company that was founded in 2018 and has been covertly building infrastructure to solve this problem. The company’s €4 million funding round, was led by P101 SGR, one of Italy’s top foreign VC firms.
Sella Direct Ventures, a FinTech-focused investor, also participated in the round.
The Numbers Behind A-Cube:
A-Cube has handled more than 70 million invoices since 2019. Currently, the platform links 120,000 entities and serves over 450 clients in more than ten countries. These are actual operational numbers that show how its electronic invoicing API and e-reporting infrastructure are being used; they are not forecasts.
Within a single interoperable architecture, the company links public authorities, financial institutions, and corporate platforms. This implies that a public authority in Italy and an ERP system in Germany can communicate via the same layer without the need for custom integration work on either end.
Why P101 Bet on RegTech:
For P101, this is the firm’s second RegTech investment, following its 2023 bet on Aptus AI. It is also the 15th transaction across Programma 103, Azimut Eltif Venture Capital P103, and Programma 103R Digital. The fund itself is partially backed by the European Union through the InvestEU Fund, which adds institutional weight to the deal.
Giuseppe Donvito, Partner at P101, pointed to a clear market signal: electronic invoicing is projected to be adopted by 90% of European companies by 2030, in a market valued at over €20 billion. That projection is what makes A-Cube’s digital tax compliance platform relevant beyond Italy.
Where the €4 Million Goes:
The funding is earmarked for three areas. First, accelerating the technological development of the platform itself, including the integration of AI models for greater automation and data quality. Second, expanding the product into compliance areas adjacent to digital tax reporting, particularly as multinationals deal with multi-jurisdictional requirements. Third, supporting international growth as European regulatory frameworks converge.
The EU’s VIDA directive, VAT in the Digital Age, is scheduled for 2028 and will require real-time tax reporting across member states. Italy already mandated electronic payments on April 20, 2026. A-Cube’s infrastructure is built to handle this kind of regulatory evolution without requiring its customers to rebuild their integrations.
The Bigger Picture for Operators:
For founders and operators building products that touch financial or tax data, this round signals something worth paying attention to. RegTech infrastructure is becoming a requirement, not a nice-to-have. The VIDA directive alone is estimated to generate over €110 billion in additional VAT revenue for European governments over the next decade, which means enforcement will follow adoption.
A-Cube is also accredited to the PEPPOL network, the pan-European procurement framework, which gives it direct connectivity across public sector entities in multiple countries. If you’re building a finance tool, an ERP integration, or a payments product that operates across European markets, understanding how e-reporting APIs work is increasingly part of the technical landscape.
Antonino Caccamo, Co-founder and CTO of A-Cube, described the company’s direction as evolving from a compliance platform into what he called an enabler of financial, tax, and operational processes. With AI integration on the roadmap, the platform is moving toward predictive capability and structured data management, not just document routing.
A-Cube operates from Milan and Ferrara, with active deployments in 10+ countries.
