Our Take

Blaine Bolus, Justin Tsang, and Ramon Berríos walked so Castmagic could run. Blaine co-founded Seated (Series C, hundreds of millions raised), hosts DTC Pod (top commerce podcast), and somehow still had time to build another company. Justin was one of the first developers at Blockchain.com back when crypto was just a weird idea people laughed at—then co-founded Upside, which sold to Ampla. Ramon built Trend.io, a UGC network for creators and brands, and got it acquired by Soona. These three didn't come to play—they came to stay.

Castmagic turns one hour of recording into a content empire. We're talking perfectly accurate transcripts, timestamped overviews, shownotes, long-format articles, email newsletters, LinkedIn posts, blog content, summaries, takeaways, and AI-powered chat instances you can share. One recording becomes 100 content assets. That's not a feature—that's a cheat code. It works for podcasts, YouTube videos, Zoom calls, sales meetings, coaching sessions, research recordings. If it has audio, Castmagic extracts the gold.

The pricing is absurd: $59 lifetime access. It was $468. That's an $409 discount for a tool used by over 100K podcasters and creators. The ROI hits in the first week. Instead of hours of editing and writing, you get minutes. Castmagic is basically a content team in your browser—one that never sleeps, never complains, and doesn't need health insurance.
