Quartr Raises $18M to Build the AI Data Backbone for Public Company Research

Jan de Vries · 2026-08-11

When you're digging into a company's financials, the last thing you want is stale or scattered data. That's the problem Quartr set out to solve, and it just got a serious boost to go bigger. The Stockholm-based startup has closed a $18 million funding round to expand its AI-ready investor relations (IR) data platform, which is quickly becoming the go-to source for hedge funds, asset managers, and even AI systems. ### What's the Deal? The round was led by Altos Ventures, an existing backer, with new investor SEB joining in. With this investment, Altos becomes Quartr's largest shareholder. This latest raise builds on a $6.3 million investment from Altos in 2024 and a $2.9 million seed extension in 2022, bringing the company's total seed funding to roughly $8.1 million. It's a clear vote of confidence from investors who see the growing demand for reliable, structured financial data. ### Why It Matters Quartr isn't just another financial data provider. It's building what it calls the "AI infrastructure for company research." The platform pulls structured, real-time IR data directly from public companies, including earnings calls, filings, and slide decks. That means everything is first-party and sourced straight from the companies themselves, which is a big deal for accuracy and trust. The company's two core products are Quartr Pro and Quartr API. Quartr Pro is an AI-powered research platform that lets analysts search across thousands of documents, with every answer linked back to its source. Quartr API, on the other hand, is a data backbone for developers, feeding structured audio, transcripts, and filings from over 15,000 companies across 65 markets into other platforms and AI systems. ### The Growth Story Quartr says it's growing at triple-digit rates with strong unit economics. Net revenue retention sits at around 120%, meaning existing customers are spending more over time. More than 800 financial institutions and tech companies use Quartr, including four of the five largest hedge funds in the world. That kind of traction speaks volumes about the product's value. ### The Bigger Picture Co-founder and CEO Oscar Küntzel puts it simply: the goal is to let others build on top of their knowledge graph so you can get an exhaustive answer to a complex query. That's the vision. As the financial industry shifts rapidly toward AI, Quartr is betting that owning the primary source—live audio, transcripts, filings, and slides—will keep it ahead of both traditional research tools and newer AI-native competitors. The fresh capital will go toward faster product development and expanding data coverage. It's not a pivot into new lines of business, but rather fuel to stay ahead of the AI shift. If you're in finance, tech, or just curious about where data is heading, this is one to watch. ### What's Next Quartr aims to build the definitive first-party data layer that both human analysts and AI systems rely on. It draws exclusively from public company IR material and doesn't train on customer queries, which is a smart privacy play. As demand for AI-ready financial data grows, owning the source and delivering it in real time could be the winning formula. For professionals in the US, this is a reminder that the race for clean, structured data is global. And with players like Quartr pushing the envelope, the future of company research looks a lot more efficient.
