Fusemachines vs Sigmoidal: overview
Fusemachines
Fusemachines was founded in New York in 2013 by Sameer Maskey, a Columbia adjunct professor, around a simple idea: train AI engineers in places big tech ignores, then put them to work for enterprise clients. Its AI Fellowship program has trained engineers in Nepal, the Dominican Republic and Rwanda. 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
Sigmoidal is a New York machine learning consultancy founded in 2016 and led by CEO Mariusz Kierski. It covers NLP, predictive modeling and generative AI, and directory listings describe staff augmentation built for long projects. One Clutch reviewer, a real estate company, used Sigmoidal to scale its internal team. Revenue estimates sit around $3 million, which makes it one of the smaller firms here.
