Maybe hire a freelance market researcher to find out? ;) Generally, something like this is going to appeal to fortune 500 companies. Smaller companies and entrepreneurs are going to be doing market research themselves. From the question it is difficult to tell if you have come into possession of such a platform, or are thinking about building one. Regardless, to succeed it's crucial that you deeply understand who your target customer is and what pain you are solving for them. Most ideas for a business stem from the entrepreneur's discovery of a solution to a problem for a certain group of people. Since who has the greatest need is unclear to you at the moment, the best thing to do might be to contact people at companies who you think have the greatest need. Find a way to get in touch with someone at the company involved in hiring market researchers, and ask them what challenges they face. You can also talk with a few market researchers themselves to get an idea of where they see the greatest demand of companies looking to hire them. Hope this helps.

I would seriously consider launching a blog and posting content of the same type to the blog, in abundance. Then add a popup box to the blog to collect email addresses. Post daily blog posts about topics related to your blog and your newsletter. If you do this consistently, over time, you will build up traffic to your blog and also get people entering their email into your popup. This is the free way to do it...
