micro1 vs KORE1: overview
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.
KORE1

It recruits for ML, LLM, MLOps and GenAI roles on contract, contract-to-hire or direct-hire terms. Contract-to-hire is the buying model to note: you pay a bill rate while the engineer works for you, then convert them to staff if it works. KORE1 reports a 17-day average time-to-hire for IT roles. Screening is done by recruiters.
