Elizabeth is the best POC 500 Startups has. She is acute in her mentoring and yet patient in helping us work through our bumps!
Srini is awesome! He's been extremely helpful with intros to contacts and guidance. He understands what it takes to build a startup since he's done it successfully before - this is the kind of angel or advisor you want on your team.
Ben has been extremely helpful in working with me to solve problems and set up experiments in our early days. Very personable but will also shoot straight with you -- highly recommend working with him.
