About us

AddVANTE was founded in the early 90s as a professional services firm committed to customer service with a team of professionals with a wealth of on-the-ground experience in providing legal and economic-financial services.

Around this initial core group, over time, a team of lawyers, economists, engineers and experts in different disciplines with specific training in various areas of business have joined.

Currently, more than 100 people offer their professional services to clients in Spain and around the world. We have offices in Barcelona and Madrid, as well as strategic partners on all five continents.

We believe that pooling experiences and knowledge, along with analysing issues from different professional perspectives, contribute a great deal to the process of analysis while, at the same time, boosting creativity.

This multidisciplinary analysis provides an excellent added value to our solutions, as it enables us to understand the current climate from a broader perspective, improves communication between professionals and enables the mainstreaming of knowledge, and offers creative proposals without losing sight of the global vision of the business or project.
