How this page is built

Computed from the SpaceNexus funding record: every figure is a count, a sum or a date over our own rows, and every sentence is a fixed template filled from them. Nothing on this page is written or estimated by a model.
A round counts when it is a published private funding round into a space company, the rule behind our quarterly funding editions and the Most Active Space Investors release.
Investor names are read from each round's recorded lead and investor fields by fixed rules: co-leads written “A / B” or “A; B” are split, hand-checked spelling variants are merged and fund vehicles are credited to the firm that manages them. The wording as recorded is shown beside any row where it differs.
Only 468 of the 626 counted rounds in our records name any investor, so this is what our records show, not a complete list of AirTree Ventures's investments.
Pages join search engines once an investor appears on at least 2 counted rounds.
No investor pays to appear here or to change what is shown.
