Javier Estella Lana

Javier Estella Lana is a Madrid-based lawyer who has served as Managing Partner of Avantia (Avantia Asesoramiento Fiscal y Legal) since 2005. Avantia is one of the leading independent Spanish firms providing tax and legal services to national and international private-wealth clients, with a team built around roughly three decades of senior experience. The firm advises top-tier Spanish and international ultra-high-net-worth individuals, family groups, artists and sportspeople, family businesses, entrepreneurs, and directors of leading Spanish blue-chip listed companies, and operates an associated family-office function (the avantia-fo.com domain used in his email).

Before founding/leading Avantia, Estella was Wealth Partner and National Director of Wealth Planning at EY Abogados (Ernst & Young). Earlier in his career he was a senior associate at Price Waterhouse (PwC), where he was one of the founding members of the firm's High Net Worth and Family Business group, helping to initiate the Spanish private-client practice. His work centers on national and international estate planning, succession and will planning, family-business governance, and joint personal–corporate tax structuring, including M&A, restructurings, IPOs, and financing arrangements for family enterprises.

He is academically active: he has been a Professor of Estate Planning at IE (Instituto de Empresa) and other institutions, and serves as an Academic Advisor and co-director of the wealth/estate-planning forum at Fundación Fide. His education includes a Law degree from the Autonomous University of Madrid, a Master in Tax Advice from IE, a PDG (senior management program) from IESE, and a Leadership in Law Firms program from Harvard Law School.

Estella has been ranked Band 1 in Private Wealth Law (Spain) by Chambers High Net Worth and has held a Chambers ranking for roughly a decade. Client testimonials describe him as "always available," someone in whom clients have "complete confidence… to provide the best advice, minimise risks, and ensure maximum legal certainty," and "a great professional by all measures."

• Primary professional lens is private wealth and family-business advisory, not venture/startup investing; any angel activity flows from advising and structuring wealth for entrepreneurial and UHNW families.
• Client base skews to established family groups, entrepreneurs, and business owners in Spain and cross-border, rather than early-stage technology startups.
• Where capital is deployed, it is most consistent with family-office allocation (succession-driven, tax-efficient structuring) — seed-stage classification per the database could not be substantiated with named deals.
• No publicly stated startup investment thesis, sector preference, or check-size range was found in primary sources.
