If the investor is a good co-founder and committed to the idea and has the network and chops to make something happen for $3000, might be a good idea for some people. But... you want a co-founder who is committed, can point you to the right way to build the MVP so that you can actually acquire customers, has a network in and some knowledge of your vertical. Otherwise, you build an MVP, give up 50% for... not necessarily very much. Now you have a weak co-founder with 50%, might make it hard to take the next step, sort out control issues, have enough equity to get more people interested and still be interesting for the founder. And if you really believe in your idea, and are the kind of strong hacker and entrepreneur that will be successful, is $5,000 that big a hurdle for friends and family, credit cards etc.?
