Questions
What is free here?
Name, type, stages, sectors, city and country, website, investment and exit counts — as aggregates across all 74 rows and row by row for the first fifteen. Contact addresses are not part of the free view and are physically absent from this page.
What does buying add?
The full export of all 74 rows in XLSX and CSV, including contact email (74 rows have one). Access follows the list, not a file: the export is rebuilt and you always download the current version.
Where does the data come from?
Source and method are described on the investor data sources page. We do not claim verification that did not happen — each row carries a confidence level. An investor who asks to be excluded is removed from both the preview and the export.
