I would like to hire a Growth Hacker

[login to view URL] is a website that delivers custom video drawings. We want to pivot and try to reach out to a new specific audience: "males between 18-23 who are dating". We want to launch a campaign #saveabro where we want to target guys who are late on preparing that perfect gift idea for their crush, and we'd offer them a 48h video delivery. We need to answer these questions: What is the profile this audience? Determine Your Audience Size? What social media sites do they regularly use? What websites do they visit for information on? Do they listen to podcasts? If so, which ones? Do they regularly read blogs? If so, which ones? What people do they follow or pay attention to online? What is their online behavior? Where can we connect with them and how?
