I did some researches about a possible product and it looks able to fill some gaps. How can I find and ask some feedback to target customers without a real product?
You can do it, you need to buy leads at a cheap price and you need to place calls and send them emails,it will be a good way to satisfy your query and also to market your product or who knows you might get some clients.
If you need leads you can mail (firstname.lastname@example.org)
I have been buying leads from them for the past 7 months and they are just great.
They charge me .30 cents per lead......their leads contain__email id,address,phone number,state,city , zip code and obviously the customers full name.
Best of luck
The answer is fairly simple, execution very hard. Sounds like your are the ideation phase, so demographic research is key. One of the most important things you need to do is create and share surveys with your target demo, now you can either buy leads and send that across, or share it with your network and ask them to share along creating the pyramid effect. Folks are 10x more likely to complete a survey if it comes from someone they know directly or indirectly.
