Professionals with specialized industry knowledge may be able to earn money by participating in paid consulting calls, surveys, interviews, and research projects through expert networks. These companies connect businesses, investors, researchers, and other clients with people who have relevant firsthand experience.

The directory below covers 141 expert network companies, grouped by the industry each one focuses on instead of in a single alphabetical list. Each company name links straight to its signup, registration, application, or contact page.

How to Use This Directory

Start with networks that match your professional background, industry experience, and geographic location. Complete each profile carefully and keep it updated as your role, responsibilities, and expertise change. When contacted about a project, review the subject matter before accepting and decline any assignment that could create a conflict of interest or require you to disclose protected information.

Expert network projects may be occasional rather than consistent. The number of invitations you receive can depend on your experience, seniority, industry, location, profile quality, and the current needs of each network's clients.

Looking for other ways to get paid for your opinions? If you don't have deep industry expertise, consumer market research is a more accessible route — see our companion guide on how to make money from paid focus groups, with a directory of legit research firms you can register with.

Frequently Asked Questions

Joining more than one expert network can increase the number of opportunities you are considered for, although registration does not guarantee that you will receive projects. Each network has its own eligibility rules, compliance requirements, geographic coverage, and areas of interest.
