Appen alternatives: who else pays for company records

micro1 publishes tiers of $100K-500K, $500K-2M and $2M+, and Polyshares quotes $100K-$2M+. SuperAnnotate gives an indicative $100K-$1M+ with a written valuation after the scoping call, and Labelbox Prism says smaller targeted datasets start around $50K and large partnerships reach $1M+. Centific, in our view the closest match to Appen, publishes no range either, though it says it gives a written estimate after the first conversation.^{15,16,17,18,19}

Appen's page ties payment to acceptance and gives no number of days. Mercor gives a clearer clock, a wire on delivery, typically within 2-4 weeks of signing. micro1 says it pays in full within 30 days of acceptance, after up to 30 days of review on its site. Polyshares and Ventra both describe 30 to 60 day terms, which for Polyshares start once the data is approved, anonymized and delivered, and for Ventra start at signing.^{11,9,20,21,22,23}

Appen's page states no exclusivity terms, and neither do Centific's or Scale AI's. micro1's published license is nonexclusive and Endless says the same of its own, while Polyshares and Labelbox Prism both say exclusive by default, with Prism listing alternatives such as single-buyer access or time windows. SuperAnnotate counts exclusivity among the things it prices, so the answer can change your number.^{9,24,25,26,27,28,29,17}

A wind-down is where Appen says the most, claiming a faster path, a prioritized response and often the complete history. Centific offers a dedicated asset-purchase agreement for wind-downs, but its FAQ uses near-identical wording to Appen's, for reasons we do not know, so do not read the two pages as separate confirmation.^10,30,31

For a truly different second look, Polyshares says it has a large appetite for companies that are winding down, closed or in bankruptcy, Pewter takes firms with 20+ full-time staff at their peak, and Ooak Data says a director, liquidator or administrator can sign. Labelbox Prism says wound-down companies are among its most active sellers, with a single payment that can happen inside bankruptcy.^32,33,34,35

Appen reported first-half revenue of $119.9M, up 17%, of which Appen China was $76.2M, up 80%, and Appen Global $43.7M, down 27%, and it names no finished deal in this program. micro1 has committed $1B over 12 months and told a court it completed more than 50 data transactions in 45 days, without naming sellers or prices. Polyshares lists four deals with names kept confidential, none of them independently confirmed.^{36,9,37,38,39}

In our view Appen is still worth a call if your company is too small for micro1 or you need a quick wind-down path, since it states no size floor. If you want numbers before that call, the quiz connects you with the buyers we work with that fit, and the seller ranking and our reviews cover the rest. On this page micro1, Polyshares, Ventra, Pewter and Grepped pay us a referral fee. Our scores and reviews don't change for it.^10,40
