The short answer is yes! There is a large group of Angel Investors in the SF Bay Area where I am located. I can actually help vet your company to see if a) currently have the traction to get an angel round b) what additions you might need to make in order to be attractive to investors and c) give you some connections I have made over the years. You would not be meeting with VC's as $500k is a Seed or Angel round. As Far as equity I can go over that with you as well. Let me know if you would like to schedule a call. I actually pitched against Mad Video from Argentina if I am not mistaken. We took 2nd and they took 1st in a startup competition in front of 3,000 people.
