Company data (HQ, sector, founding year) comes from each startup’s own record. Funding figures are cross-referenced from the deals tracker’s most recent verified round for that company – not a lifetime-total field, since that field is not yet consistently populated across startup records.

This table currently shows the most recent verified round per company rather than lifetime capital raised, since a reliable lifetime-total field is not yet populated for most startups on Sesamers. 106 companies carry the cleantech tag in total; these six have the most complete cross-referenced records so far. Energy storage is the most common secondary tag – BATTIA, Rebaba and WLF Energy all carry it.
