On September 1, 2026, Wafer, an AI start-up developing a technology that continuously optimizes AI inference deployments, announced it has raised $40 million in a Series A financing round. The round was co-led by Marathon and Chemistry, with participation from Wing, AMD Ventures, and Outset Capital, as well as existing investors Fifty Years and Y Combinator. Wilson Sonsini Goodrich & Rosati advised Wafer on the transaction.

The capital will support Wafer's efforts to automate more of the inference optimization loop and advance its work toward inference infrastructure that continually improves.

The Wilson Sonsini team that advised Wafer on the transaction included Rezwan Pavri, Lester Ang, Andrew Lu, and Kennedy Myers Holloway.
