HumanAPI sells high-quality human data to Fortune 500 companies and frontier AI labs, and their requests are often very specific. To meet them, we needed to know exactly who was providing the data. I designed HumanAPI 2.0 around that problem. I created an ID card style onboarding where each step was recorded as audio by the user, so we could capture their voice, background, language and skills from the very first minute. That gave us a clear profile of every contributor, so when a lab asked for a very specific type of person, we could find them and deliver fast.
