I like that WhoGoes has a simple UI that's clean and straightforward, with no learning curve or clutter. I can just search for an event and immediately see who's attending. I appreciate the fully enriched company and individual profiles, giving me all the information like name, title, company, and email in one place, so I don't need to cross-reference multiple tools to build a prospecting list. The source post feature is a real differentiator, as every contact is linked back to their actual LinkedIn post where they mentioned attending the event. This makes my outreach feel personal and relevant instead of just a generic cold email. The initial setup was super easy, taking me only 5 minutes to get started.
