The company went public on the Nasdaq Global Market (ticker FUSE) on October 23, 2025, through a merger with the SPAC CSLM Acquisition Corp. Today it sells its own AI Studio and agent products alongside forward-deployed engineers and small squads of data and ML specialists who work inside client organizations.

Sigmoidal
