Recently I've finished the series of illustrations for StayInDrops, a startup in Boston, MA, helping to test your business ideas before going to the crowdfunding platforms.
You can briefly describe your product or service and get a valuable feedback from the early potential customers.
No risks, since you are not selling but only testing your business ideas.
You can learn more about your target audience by asking your own questions and getting results with all demographics in 14 days.
Definitely worth checking out!
