Clients

Who do we help?

Legal Stones works with companies that need legal clarity on artificial intelligence, the AI Act, data protection and contracts — whether or not they have an in-house legal team. It also collaborates with AI consultancies and integrators.

AI Legal Assessment

  • Companies rolling out Artificial Intelligence tools (ChatGPT, Copilot, Gemini, Claude, and similar).
  • SMEs that want to see real use and document governance, data, contract and training needs.
  • Teams that need a documented plan before an external milestone.

Contracts

  • Companies without an in-house legal team that need contracts reviewed before signing.
  • Businesses that regularly negotiate with suppliers or clients.
  • Teams that need clear summaries of clauses and contractual risks.

AI Act Quick Check

  • SMEs that want a 30-minute orientation on whether the AI Act may affect them.
  • Teams already using ChatGPT that do not know if the next step is the Assessment.
  • Leadership that needs to decide what to review, without starting with a long engagement.

About me

Hello, I am Lucía Piedras

I am the founder of Legal Stones, a specialised legal consultancy in artificial intelligence for companies.

My professional path has taken me through contracts, legal documentation and risk analysis, developing a very practical approach: understanding what is really behind a document and spotting what can become a problem before it does.

With the arrival of artificial intelligence, I decided to take that same approach to the new scenario companies face: understanding their legal risks and learning to use AI responsibly.

Today, at Legal Stones, we work in two areas:

Preventive law and Artificial Intelligence.

We review contracts, NDAs and agreements to help you understand what you are accepting, what risks exist and which points you should negotiate before signing.

And we help companies understand and manage their use of artificial intelligence, through AI legal assessments, AI-literacy training and orientation related to the AI Act.

My goal is not to give you a document full of legal jargon.

It is to give you clarity so you can make better decisions.

I work 100% remotely, with a close, practical approach tailored to each company.

At Legal Stones we believe in:

Clarity over jargon Prevention over conflict Analysis before decision Innovation with responsibility

Because the sooner you understand the risk, the more options you have to manage it.
