micro1 vs Appen: which should license your company's data?

Both also run contractor work, which is a separate business from buying company records. The Appen reviews we sampled came from contract workers and tool users, not businesses that licensed data, so its 1.5 tells you little about how it treats a company selling records. micro1's 4.7 also covers the whole company, not only its data deals.^{7,17,16,18,15}

Money behind the buyer is a fairer test. micro1 has committed $1B to buying company data and says it is financing that with capital from Citi and Hercules Capital, and it told a court it completed 50+ data transactions in 45 days, without naming sellers or prices. Appen reported $119.9M of revenue for the first half of FY26, up 17%, of which Appen Global was $43.7M, down 27%, and it names no finished deal in this program.^{19,20,21,22,10}

A company with 30 to 200 people and a shelf of process documents fits micro1's own description closely, and its range tells you what it says it pays. Companies that are closing should look harder at Appen, which promises a prioritized response on wind-downs and can often license your complete history.^23,6,4

Appen says it answers within two business days and puts a mutual NDA in place before further discussion, so asking costs little. When its quote arrives, ask micro1 for a written number too, and ask Appen what its page leaves out: exclusivity, whether you approve buyers, and how many days after acceptance the money lands.^24,10
