Appen

What it wants

Operational documentation (procedures, wikis, QA), decision and escalation records (support desk, ITSM, CRM, project tracking, messaging) and systems of record (ERP, warehouse, contracts, HR, procurement).

What it publishes about price

No figure published. "Terms are agreed in writing before extraction begins"; price follows uniqueness, how connected the systems are, volume and how far back the records go.

Who it takes

Companies of any size; those winding down are answered first.

How the holder is paid

"Payment is on acceptance rather than submission."

Who removes personal data

Appen covers extraction, anonymisation and transfer at no cost to the company; personal data is removed, with synthetic rewrite where the workflow has to survive the redaction. The company approves a sample pack before anything is licensed.

What it pays for an introduction

Nothing published.

We are not Appen's agent, partner or representative. If you hold data it might buy, we can put it in front of Appen and every other buyer that fits at the same time.
