Applying and requirements
Check payout-country support
Official information
OpenTrain publishes a payout-country list. If a country is absent both there and in payout setup, it says it cannot currently pay into that country.
This concerns bank payout availability, not citizenship or permission to join every project. The list is dated 1 May 2026; check the linked current list and setup.
OpenTrain’s direct contracts use employer-funded milestones. After the agreed work is submitted and approved, payout starts to the contributor’s connected bank account.
Daily payout scheduling follows approval; bank and country processing times vary. Contract amounts differ. External job-feed listings follow the external platform’s payment rules.
OpenTrain uses Stripe-hosted setup for payouts to local bank accounts in the countries on its payout-support list. Contributors do not need to create a separate account on stripe.com.
The list concerns payout support, not project eligibility. If a country is absent from both the list and payout setup, OpenTrain says it cannot pay out there.
Job recommendations consider skills, experience, languages and location. Employers may require an AI interview, review proposals and create a contract when they hire.
No minimum work or income commitment. External listings have separate screening and contract rules.
Identity verification and work location can differ
Worker report
In August 2026, a Trustpilot reviewer disputed cancellation after identity verification. OpenTrain replied that the project required work from certain countries and that account sessions outside them caused a separate location-compliance concern.
One contested account with a company reply; neither party’s records were independently inspected. No country list or platform-wide rule is inferred.
Selected public accounts. Experiences are self-reported.
Contrasting payment and support accounts
Accounts cover July–August 2026
One July 2026 Trustpilot reviewer described regular payment and good communication. An August reviewer praised workflows and support; another alleged approved work had not been paid. OpenTrain replied asking the latter to contact support and saying completed work would be compensated.
Three self-reports. Trustpilot says the company invites reviews; the complaint’s resolution is unknown.
