We are committed to protect and safeguard our clients’ interests at all times.  We maintain strong relationships that are supported by mutual trust, confidentiality and respect.

We’re full-service, so you’re fully represented.

When working with startups, we know that they (and their teams) need to dream and create new universes, new unforeseen markets, even if that means taking a non-customary approach to the Law and the regulations, they need to push the envelope without breaking it

We successfully negotiated and obtained the first ride-sharing or car-hailing regulation in Latin America, acting as counsel to Cabify.


We are a law firm focused on helping venture-backed startups set up in Mexico, Mexican startups launch their operations abroad, and international VC funds invest in Mexican startups.
