Mateo founded Háblalo, an app providing a free, mobile Augmentative and Alternative Communication (AAC) device for people with disabilities.
After downloading Háblalo, users take a brief quiz regarding their access requirements resulting in a fully customised interface based on disability type. Depending on the customisation, the app may include features such as a pictogram library, phrase construction tools, quick-access phrases, subtitling, and translation. Háblalo also has tailored content, accessible by scanning a QR code at participating businesses and public buildings.
In 2023, Mateo won the Entrepreneur of the Year Award supported by TFG Asset Management. The recognition led him to connect with entrepreneurs and industry leaders in Europe, where he eventually hopes to expand Háblalo. The connections that he made at the Summit have provided him with a worldwide network, and significant global momentum due to his award.
By 2024, 300,000 people used Háblalo. He is also the Founder of Asteroid Technologies, the umbrella organisation behind Háblalo that focuses on accessible technology. In addition, Mateo has founded Apgreid, an edtech company, and Grondplek, a 3D printing venture. In 2025, Háblalo has already grown to 500,000 users.
