FAQ

Frequently Asked Questions

Everything you need to know about listing your company and winning clients on OpenTrain AI.

Is it free to list my company?

Yes. Creating your company profile and appearing in buyer searches is free. To submit proposals, there is a low monthly fee you can turn on or off anytime. No commission on projects you win.

How do I receive RFPs?

When buyers post a project, we match it to providers based on services, tools, and experience. You get notified when a project fits your company. You can also browse all open RFPs and propose on any that interest you.

Can I see who the buyer is?

Some buyers stay anonymous during early evaluation. You still see the full project scope, tools, timeline, and budget. Buyers typically reveal their company name when they shortlist you or after signing an NDA.

Do I have to use OpenTrain's tools to deliver the work?

No. OpenTrain is for finding clients, not running projects. Deliver the work in the buyer's tools, your own platform, or whatever you agree on. We only handle proposals, messaging, and optional payments.

What goes in a proposal?

Your pricing, timeline, team capacity, relevant experience, and approach to the project. You can attach documents if needed. The standard format helps buyers compare proposals quickly.

How do reviews work?

After a project, buyers can leave a verified review on your profile. More reviews help you rank higher in buyer searches and win more work.
