GuestRadar

GuestRadar helps podcast hosts and producers book better guests by showing who drives measurable audience lift. Connect your podcast hosting analytics (Apple Podcasts, Spotify for Podcasters, and major hosts via RSS + attribution links), then track episode-level outcomes like follower growth, completion rate, click-through, and newsletter signups. The app builds a “guest impact profile” by combining public signals (social reach, newsletter size estimates, topic authority) with your private performance data to predict which guests are likely to move your numbers. It also streamlines outreach with lightweight CRM features: templates, scheduling links, and a one-page guest brief generator. This is not a magic ‘growth hack’—it’s a decision tool to reduce wasted booking time and focus on guests with proven traction for your specific audience.
