Summary
A-Cube, a Milan-based RegTech startup, has secured €4 million in Series funding led by P101 SGR, with co-investment from Sella Direct Ventures. The round underscores growing institutional confidence in European tax compliance automation, particularly as regulatory frameworks shift toward mandatory digital reporting. P101 SGR, managing €500 million in assets with a track record of 300+ transactions, led the deployment alongside Sella Direct Ventures, signaling confidence in the company's market positioning and execution trajectory.

Founded in 2018, A-Cube has built an API-first platform for managing and exchanging digital tax documents, including electronic invoicing and real-time reporting capabilities. The company has achieved meaningful scale, having processed over 70 million invoices to date and serving more than 450 customers across 10 European countries. This operational footprint demonstrates traction in a compliance-heavy sector where network effects and regulatory adoption create durable competitive advantages.

The company intends to deploy the capital toward three strategic priorities: expanding core product capabilities, building adjacent solutions that complement digital tax reporting, and integrating artificial intelligence into its platform architecture. According to Antonino Caccamo, A-Cube's co-founder and CTO, the investment arrives at an inflection point for global taxation, as regulatory changes and technological innovation converge toward increasingly digital and integrated reporting models. Caccamo emphasized that A-Cube aims to provide infrastructure enabling companies to manage complex multi-country environments while positioning compliance as a strategic rather than purely operational function.

Giuseppe Donvito, Partner at P101, cited substantial market fundamentals to justify the investment thesis. Electronic invoicing adoption is projected to reach 90% of European companies by 2030, creating a serviceable addressable market exceeding €20 billion. This expansion is being materially accelerated by regulatory initiatives, particularly the EU's VAT in the Digital Age (VIDA) directive, which mandates real-time tax reporting across member states. The combination of regulatory pressure and market scale positions RegTech providers focused on tax compliance infrastructure for pronounced growth, placing A-Cube squarely within a favored investment category for institutional capital.
