The core team is 2 friends of mine and me. All of us are Computer Science students. I am the one who spends time designing, recruiting partners for our platform.
Early in the project, some people joined along to work few hours a week (for free), but lost motivation to work on it pretty quickly. Mind you, all of them came from my personal network.
A week ago a random business student contacted me saying she has been thinking about the same idea for quite some time, but was missing the technical capabilities. She would like to join us and collaborate on growing the platform (marketing, business, recruiting of partners, social media management). She offered to do it for free and mentioned that she would likely work on a similar platform regardless if we partnered up or not.
After the first experiences of people joining us, I am hesitant to accept such offers. It usually resulted in people not doing the tasks and with me overtaking their responsibilities after a month of inactivity.
What would be your take and how would you evaluate a candidate who is willing to work for free?
