Sigmoid vs Fuzzy Labs: overview
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.
Fuzzy Labs
Fuzzy Labs is a small MLOps consultancy incorporated in January 2019 and based at the GM Digital Security Hub in Manchester. It works side by side with data science teams to get models into production with less technical debt, describing itself as the client's in-house MLOps team and an extension of that team. Clients range from startups to policing and secure government work, and some roles require UK security clearance. The company says it doubled revenue in its most recent year and runs a fellowship to train new MLOps engineers.
