Company profile
researched Sep 2026Valarix is an artificial-intelligence financial technology platform focused on corporate tax compliance and bookkeeping across the USMCA corridor. Its cloud software applies machine learning models to reconcile invoices, automate tax classifications, and produce audit-ready deliverables, with the stated aim of completing such outputs in under an hour. The company describes its product as an autonomous assistant for accounting — a "JARVIS for accounting" — intended to help fast-growing companies avoid structural tax penalties and identify overlooked tax credits.
Under the ContaAyuda brand at contaayuda.com, the company also operates a Spanish-language fiscal and financial content property. That site aggregates technical articles and videos, a public FAQ covering tax and accounting questions, a directory of accountant profiles linked to their recent content, and a calendar of fiscal and accounting deadlines and community sessions. Content is contributed by users and accountants, with publications that include video given priority placement.
The platform is positioned specifically for the Mexico–United States market, taking advantage of the alignment between the two countries' tax regulations and the large volume of XML invoice data available in Mexico, which is used to train specialized AI models for transaction categorization and error reduction in tax processes.
Founding story
Valarix was founded by Christopher López and Mayank Desai. López, educated at Tecnológico de Monterrey, previously worked at iuvity and built ContaAyuda, a tax practice that used AI to serve more than 200 clients with a small team, and has passed through acceleration programs including Techstars and Endeavor. Valarix was created to bring that automation-driven efficiency to a larger scale.
