Stockholm-based financial data company Quartr has raised $18 million in a funding round led by existing investor Altos Ventures, with participation from new investor SEB. Quartr provides structured data from public companies, including earnings calls and other investor relations materials, through its Quartr Pro research platform and Quartr API. Founded around the collection and structuring of first-party information from public companies, Quartr provides data and tools used for financial research and AI-driven applications. Its offering is split between Quartr Pro, an AI-powered research platform aimed at financial professionals, and Quartr API, which allows businesses and developers to integrate Quartr’s data into their own products and workflows. The $18 million round comes as Quartr positions its data infrastructure between traditional financial research tools and the emerging generation of AI applications.
