BairesDev vs micro1: overview
BairesDev
BairesDev was founded in Buenos Aires in 2009, is headquartered in San Francisco and employs several thousand engineers across Latin America. Buyers can choose staff augmentation, dedicated teams or project delivery, and the AI practice covers ML, data engineering and generative AI. It is a practical choice when one contract needs to cover AI engineers and the software developers around them. As a generalist, though, its AI depth varies by engineer, and rates are not published.
micro1
micro1 was founded in 2022 and is based in California. Its AI recruiter, Zara, interviews every applicant for 20 to 40 minutes, which lets it screen in high volume. Buyers can take contractors hourly or monthly and start with a one-week test. It raised a Series A at a $500 million valuation in September 2025, and most of its business now supplies experts to AI labs. Product teams can still buy engineers, but an automated interview is not an engineer's review.
