About this data
Counts are records in the Zalarma investor database, as of 2026-11-01: angels, venture firms and their partners, micro-VCs, family offices, corporate VCs and accelerators that list startup investing. One investor can appear in several stage or sector rows. Stage, sector and check size come from what each record lists, so not every record has every field. Counts under 10 are not shown. Firm names are listed; we do not publish personal contact details on this site. Read how we build and check the data.
