# Blocks Software > Blocks Software B.V. is a Dutch software company that develops AI-powered tools for accountants. Its flagship product, Luca, is a virtual assistant that uses Retrieval Augmented Generation (RAG) to give accountants fast, verifiable access to professional standards, legislation, and firm-specific knowledge — improving both productivity and quality of work. > Blocks operates under the brand name "Blocks – Accountancy Intelligence" and is headquartered in Groningen, the Netherlands (KvK 98973991). The company was founded by Nick Venhuizen RA (co-CEO), Arthur Jager (co-CEO), and Lucas Castelo (CTO). Blocks serves audit firms, compilation practices, technical departments, compliance teams, and administration offices across the Netherlands. Luca consolidates fragmented professional knowledge — spanning Dutch GAAP (Richtlijnen voor de jaarverslaggeving), legislation and regulations, and firm-specific methodologies — into a single searchable platform. It provides accountants with sourced, verifiable answers and assists with drafting consultation memos and documentation. The platform follows a strict "accountant in the loop" principle: the accountant always remains responsible for final decisions, while Luca accelerates research and improves consistency. Blocks prioritises security and compliance. All data is processed exclusively within the EER, hosted on Hetzner servers in Germany, and Blocks is fully GDPR/AVG-compliant. The platform is model-flexible and designed to meet the requirements of the EU AI Act. --- ## Pagina's - [Klantverhaal downloaden](https://blocks-software.com/klantverhaal-downloaden-vermetten/) - [Whitepaper downloaden](https://blocks-software.com/whitepaper-downloaden/) - [Fullstack Developer](https://blocks-software.com/werken-bij/fullstack-developer/) - [Werken bij](https://blocks-software.com/werken-bij/) - [Vacature Senior Security & DevOps Engineer](https://blocks-software.com/werken-bij/senior-security-devops-engineer/) - [Privacyverklaring](https://blocks-software.com/privacyverklaring/) - [Careers](https://blocks-software.com/en/werken-bij/) - [Privacy Policy](https://blocks-software.com/en/privacyverklaring/) - [Over ons](https://blocks-software.com/over-ons/) - [Demo aanvragen](https://blocks-software.com/demo/) - [Request a Demo](https://blocks-software.com/en/demo/) - [About Us](https://blocks-software.com/en/over-ons/) - [Home](https://blocks-software.com/) - [Home](https://blocks-software.com/en/) --- ## Berichten - [Hix Podcast: Afstoffen](https://blocks-software.com/nieuws/hix-podcast/) - [Hix Podcast: Afstoffen](https://blocks-software.com/en/news-2/hix-podcast-afstoffen/) - [Luca helps accountants navigate professional practice information](https://blocks-software.com/en/news-2/luca-helps-accountants-navigate-professional-technical-information/) - [Luca helpt accountants hun weg te vinden in vaktechnische informatie](https://blocks-software.com/nieuws/luca-voor-vaktechnische-informatie/) --- > Blocks Software B.V. — Suikerlaan 23b, 9743 DA Groningen, the Netherlands — KvK 98973991.
