We are the leading private platform for tax filing in Spain and Mexico. Over 4 million users and more than 2 million tax returns filed back us up.

We combine the power of AI with the expertise of over 200 tax professionals with a dual purpose: to free individuals, freelancers, and businesses from the burden of tax bureaucracy, and to fight to recover every euro and every peso they're entitled to. Over €300M saved for our users proves it.

Our HumanAI system brings together two complementary forces: AI analyzes, detects, and simplifies; human experts interpret, review, and apply judgment. AI reaches where humans can't, and vice versa.

What we do:

🔹 For individuals — Your taxes and paperwork, done right. Our AI cross-references your data against 250+ deductions to find the savings others miss. Experts validate every result.

🔹 For freelancers — Your accounting firm, but smarter. AI that automates the repetitive, and a dedicated expert for what requires judgment.

🔹 For companies — The tax benefit your entire workforce actually uses. Tax wellness programs for employees and clients, with 24/7 smart advisory.

🔹 For banks, fintechs, and insurers — Embeddable tax infrastructure via API. Integrate intelligence and trust directly into your channels.
