About BlockBuilder UG (haftungsbeschränkt)
BlockBuilder UG (haftungsbeschränkt) develops AI and blockchain solutions for German-speaking mid-market companies with a consistent focus on data sovereignty and GDPR compliance. Instead of processing sensitive data in US clouds, BlockBuilder relies on on-premises AI and European infrastructure: AI models that run in-house or in EU data centers, ensuring that business and personal data never leave the company. The core offering centers on two products: prAIvicy, a data-protection-compliant AI assistant with integrated legal database for regulated industries, and Ada, an industry-configurable AI back-office platform for property management companies and law firms that automates recurring administrative work such as mail intake, document handling, and routine correspondence. Additionally, BlockBuilder offers consulting and software development around AI agents, on-premises AI, smart contracts, and DeFi. The target audience consists of DACH B2B companies that want to leverage AI productively without taking on compliance risks.
