Santiago Mediano Abogados and Reversa: continuous regulatory advice for clients that operate in several countries

The firm is bringing Reversa into its practice to analyse the regulation that applies to its clients, support legal research and contract review with official sources, and anticipate regulatory change in the markets where they operate.

• Firm: Santiago Mediano Abogados, a business law firm.
• Offices: Madrid and Lisbon.
• Practice areas: technology and data protection, intellectual and industrial property, media and entertainment, fashion and distribution.
• With Reversa: legal research, contract review, Radar and agents specialised by practice area and client.
• Partnership: since September 2025.

Santiago Mediano's clients are companies that operate in several countries, in sectors with a growing regulatory load. Beyond knowing what is new, they need to understand which obligations affect them, in which jurisdictions and what they should do.

Answering with rigour means finding the regulation that applies in each jurisdiction, checking it against the official sources, reviewing contracts in light of that framework and spotting the changes that may affect each client. The firm wanted to build this work into its advice to international clients in a systematic way.

Working with Reversa supports the analysis of the regulation that applies to each client in the relevant jurisdictions, with references to the official sources so every conclusion can be checked. Agents specialised by practice area support regulatory monitoring, so lawyers can spend more time interpreting what it means and deciding with the client how to act.

• Regulation with verifiable sources. Reversa supports finding and analysing the applicable rules, their obligations and their application dates, with references to the official sources.
• Monitoring tailored to each client. Starting from the regulatory matrix the firm builds, the agents help identify relevant updates, and the legal team assesses their scope and the measures to take.
• The firm's judgement in every decision. Lawyers validate every conclusion and agree with the client how to act.
• Confidentiality. Each client's information is handled in a private environment, with data hosted in the EU and ISO 27001 certification.

• Multi-jurisdiction legal research. The team is bringing Reversa into its analysis of the regulation of Spain, the European Union and other markets where its clients operate, with references to the official sources.
• Contract review against the law. Reversa supports checking contracts against the regulation of each jurisdiction and helps identify the clauses that may need changes, and why.
• Intellectual and industrial property. The firm has set up an agent specialised in media, entertainment, music and video games to help identify the updates that matter for protecting and registering its clients' rights.
• AI and data protection. A second specialised agent follows legislative initiatives in the European Union and Spain, including those on protecting minors online. This helps the firm assess their possible impact before new obligations take shape.
• Client communication. The firm is launching alerts tailored to each client's sectors and products, as well as newsletters on the changes that may affect their business.
• New services. Spotting rules early supports the design of legal services, such as the firm's digital compliance offer, which brings together DORA, NIS2, the AI Act and eIDAS.

• International reach. The firm has supported the rollout of Reversa at clients with international activity, among them a multinational industrial group, covering the regulation of Spain, the European Union and Poland.
• From one-off matters to continuous support. The model lets the firm offer each client permanent monitoring of its regulation, from the initial assessment onwards.
• Verifiable rigour. Conclusions that rely on Reversa are linked to their official source.
• New legal services. Monitoring regulatory change feeds the design of new advisory offers, such as the firm's digital compliance offer.

The model aims to give the companies Santiago Mediano advises continuous regulatory monitoring, grounded in verifiable sources and adapted to their international activity:

• General management. Visibility on what regulation requires before entering a market, launching a product or closing a deal.
• Legal. Support in analysing the jurisdictions that matter to the company, with references to the official sources and reviewed by the firm.
• Compliance. A map of obligations linked to their source rules, the base for monitoring and updating the company's regulatory framework.

"What matters is not receiving more alerts, but understanding which ones affect each client and what they should do. Reversa helps us follow regulation and check the sources; our job is to put that information in context and support the client in their decisions."
