Accountable was founded in 2017 by Rodolphe Ardant, Nicolas Quarré, and Augustin de Camboulas. Headquartered in Brussels, Belgium, the company developed a holistic mobile app designed to support self-employed professionals. Unlike traditional tax refund tools, Accountable helps users connect expenses, create and manage invoices, and access insights on VAT and tax deductibility. Its goal is to optimize taxes early in the business process while providing an end-to-end solution for managing self-employment finances.
