What Big Onion does
Big Onion (legal entity BIG ONION TECH SL, CIF B67652222) is a Spanish technology consulting boutique headquartered in Madrid at calle Cirilo Martínez Novillo 37, with a secondary office in Barcelona. The firm operates with a two-person founding team — Cristina Aranda and Paul Van Branteghem — and positions itself as an experienced group of "solvers" focused on digital business innovation for enterprise and public-sector clients. Its service portfolio comprises four modular offerings delivered separately or jointly: DUE Intelligence IT (IT due diligence and assessment), Tech Boutique (strategic IT consulting, advisory, and project execution for innovation initiatives), Creación de Ecosistemas de TI e Innovación (IT and innovation ecosystem build-out), and Formación (upskilling and reskilling programs for digital competencies).
The firm's methodology is built on human-centered design, applied ethics, cybersecurity-by-design, and a deliberately informal, humor-based client engagement style intended to convert one-off clients into long-term network members. Underlying technology capability spans Solution Architecture, Software Development, Big Data, Artificial Intelligence, Intelligent Process Automation with NLP, Blockchain, Cybersecurity, and IoT, which the firm applies across projects in Marketing, Energy, and Banking. Big Onion is GDPR-compliant (EU Regulation 2016/679) and its go-to-market is sales-led direct professional services — no channel partners, no self-service, no productized SaaS. The customer base is described qualitatively as IBEX35 companies and multinationals, with no named logos or case studies publicly disclosed. The firm maintains presence on LinkedIn and Twitter, and the founders are co-founders of Spain AI, MujeresTech, and Fundación ELLIS Alicante, embedding Big Onion within Spain's principal AI and women-in-tech ecosystems.
