Sigmoid vs micro1: 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.

micro1

micro1 was founded in 2022 by Ali Ansari and built from the start around an AI recruiter, called Zara, that interviews and screens applicants. The company acts as employer of record for the engineers it places, offers full-time hires and managed teams, and lets you test any engineer for one week at no risk. Rates are fixed by seniority. Its growth has come increasingly from supplying human data and experts to AI labs, and Reuters reported a Series A at a $500 million valuation in 2025.
