Quantillium

Quantillium offers standardized global corporate filings and financial data from 60 stock exchanges via an API. The job it does: building software for you when nothing off the shelf fits.

Who is it for? Mostly companies with a specific process to automate. Alongside the main category they mention Financial Services. As a very small company team themselves (1 to 10 people), they tend to serve customers of a similar scale best. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

Quantillium is based in New York, New York. Their site is quantillium.com.

Our checklist for this category: portfolio relevance, who owns the code, and how they handle changes. Ask for a trial on your own data, not a canned demo.

If you have worked with Quantillium, tell the next buyer what you paid and what surprised you. That is the part of this page we cannot write.
