We believe investors deserve more than spreadsheets.

MercuriusData was built by a small team of investors and engineers who got tired of the gap between what traditional stock screeners show and what actually matters when evaluating a company.

We built the tool we wished existed: one that reads annual reports the way we would, explains its reasoning, and gives us a second opinion powered by the world's best AI models.

What Drives Us

Transparency Over Black Boxes

Every score comes with an explanation. We don't hide behind algorithms — we show our work so you can form your own view.

Depth Over Dashboards

The market is full of tools that show you 50 metrics at a glance. We'd rather show you 6 that actually matter, with the context to understand them.

Independence

We don't sell financial products. We don't take commissions. We built a tool for investors, funded by subscriptions. Our only incentive is to make the analysis useful.
