Greg Joseph S.J. Tiongco

Greg Joseph S.J. Tiongco is a co-managing and founding partner of Tiongco Siao Bello & Associates Law Offices, whose practice underpins the firm's recognition as FinTech Law Firm of the Year in the Philippines at the Corporate INTL Global Awards 2024. The award reflects the firm's capabilities in advising the country's fast-growing financial-technology sector.

Greg Joseph S.J. Tiongco is a co-managing and founding partner of Tiongco Siao Bello & Associates Law Offices, one of the most active and well-known law firms in the Philippines. He co-founded the firm alongside John Philip Siao and Karlo Bello, and it has since grown to operate offices in Metro Manila, Cebu City and Davao City, serving an international client base drawn from across Asia, North America and beyond. With a career spanning around two decades, he is recognised for his extensive experience across corporate law, mergers and acquisitions, litigation, labour law, and data privacy and compliance. He graduated with honours from the Ateneo de Manila University School of Law, where he was a silver-medal recipient, and is a member of the Philippine Bar.

Tiongco's professional standing has been acknowledged well beyond a single award. He has been named among the top clients' choice lawyers in the Philippines, listed among the top 50 technology, media and telecommunications lawyers in Asia by Asian Legal Business and Thomson Reuters, and recognised among Asia's leading disputes lawyers. He has acted as counsel on major matters, including one of the largest acquisitions of government assets in the country and the facilitation of the entry of the Philippines' third telecommunications provider, and provides corporate counsel to Philippine conglomerates, multinationals and listed companies, frequently working alongside international law firms.

Financial technology in the Philippines has expanded rapidly, driven by digital payments, mobile financial services and a large, young population adopting new financial tools. Advising this sector calls for lawyers who can combine corporate structuring, regulatory compliance and data-privacy expertise, guiding companies through licensing, product design and the protection of the personal and transactional data at the core of their operations. Tiongco's experience across corporate, technology-facing and data-privacy work positions the firm to serve fintech founders, investors and established financial institutions alike, from early-stage ventures seeking to launch a product to larger businesses managing regulatory relationships. The regulatory dimension is central to fintech practice. Companies operating in payments, lending and related fields must navigate licensing regimes and the supervision of financial authorities, while also meeting obligations on consumer protection and the handling of sensitive data. A firm advising the sector must therefore be able to move between transactional work, such as fundraisings and commercial agreements, and the compliance analysis on which a fintech business depends, an alignment reflected in the firm's recognition among Asia's leading technology, media and telecommunications lawyers.

With clients spanning many industries and jurisdictions, the firm is well placed to advise on the cross-border dimensions that increasingly characterise fintech businesses. Its recognition as FinTech Law Firm of the Year in the Philippines at the Corporate INTL Global Awards 2024 affirms both its role in a dynamic sector and the depth of experience that Tiongco and his partners bring to it.
