The announcement combines a $42M seed and a $75M Series A; I treat the combined $117 million as one financing and include each tranche’s named leads.
Published by hand (wsj.com): "Parallax, which was founded by a Stanford University graduate who previously co-founded a defense hardware company, has raised $117 million to enter the market for a key piece of equipment made by industrial giants: gas turbines.": Checked by hand: The WSJ states the $117M; parallax.ai's homepage links that article ('Announcing $117M raised'), which settles identity.

Parallax builds smaller natural-gas turbines, using 3-D printing, to provide on-site power for AI data centers.
AI data centers face a projected 65GW-plus gap between committed compute and available grid power by the end of the decade, while existing turbine OEM delivery times are slipping into the 2030s. Parallax is betting that roughly 10-megawatt, container-shippable turbines with 3-D-printed cores, fewer parts, and more common materials can be manufactured and deployed faster for on-site data-center power.
