Brainpool AI vs micro1: overview
Brainpool AI
Brainpool AI, which says it has operated since 2017 (directories give 2016), is a London company founded by researchers who met at University College London. It built a network of about 500 AI and ML experts from universities such as UCL, Oxford and Cambridge and sells access on a project basis alongside consultancy. More recently it has moved toward its own agent platform, Cortex. Buyers get academic depth by the project, but not dedicated full-time staff.
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.
