Inside Startup Battlefield is back in our feed with episode three. There are 180 companies solving crucial problems that didn’t make it to the Disrupt stage, but that doesn’t mean they’re making any less of an impact. TechCrunch writers Devin Coldewey and Harri Weber take us on a walk through the Expo Hall and let us listen into their conversations with a handful of the most interesting companies in the Battlefield 200.

New episodes of Inside Startup Battlefield drop every Monday. Be sure to check out all of the other podcasts in the TechCrunch Podcast Network: Found, Equity, The TechCrunch Podcast, Chain Reaction and The TechCrunch Live Podcast.
