Quantiphi vs Sigmoid: overview
Quantiphi
Quantiphi has worked only on AI, machine learning and data since it started in 2013, and it now employs somewhere between 3,000 and 4,000+ people, depending on which directory you trust. That makes it the biggest company on this page by a wide margin. Its staff augmentation product, Elastic Staffing, was built with AWS for teams that need generative AI or ML specialists faster than a normal hiring cycle allows. In one company case study, a U.S. energy supplier brought in eight specialists through the program and reported savings of more than $570K (per company website; independently unverifiable). The firm is headquartered in Marlborough, Massachusetts, and Google Cloud named it 2025 AI Partner of the Year for North America.
Sigmoid
Sigmoid is a San Francisco company founded in 2013 that built its business on data engineering for Fortune 500 consumer brands and later moved deeper into machine learning and generative AI. Its own sales deck describes a hybrid model: each client requirement is classified as either a project or a staff-augmentation need, and augmented staff are billed monthly with a dedicated project manager and engineering manager on top. The company reports more than 200 ML models put into production and over 5,000 data workflows built (per company materials; independently unverifiable). Delivery runs from more than 12 centers across the U.S., Europe, Latin America and India.
