Common questions
How and when does Ethos pay experts?
Within 30 days of your invoice, after a project closes. Some AI training platforms pay weekly, so plan for the longer wait.
Is Ethos regular AI training work like rating chatbot responses?
No. Ethos is an expert network. AI labs, investment funds and large companies pay for your domain knowledge (deal analysis, clinical reasoning, legal logic, financial modeling) in three formats: multi-week consulting engagements, 30 to 60 minute advisory calls, and research surveys. Listings like this one are the AI-lab engagements, where you write or review expert material for a model.

Between 5 and 20 hours a week. At $70/hr that is $350 to $1,400 a week. You set your own hours.

The listing asks for 4+ years in procurement, sourcing, or vendor/supplier management; direct ownership of running RFPs/RFQs and negotiating or reviewing vendor contracts and SLAs; and expert-level document, spreadsheet, and slide craftsmanship, with excellent written communication and attention to detail.
