StartUp is back: Season 4 of Gimlet’s flagship podcast StartUp has begun, kicking off with a three-part mini-series on what’s happening in the company — and it’s all about growth. The company is hitting a point of “high spending, low revenue” as they develop new shows and are concerned about their cost structure. “Since the start of the year, Gimlet has more than doubled in size. And while growth is often the goal for a startup, it also costs a lot of money … How are they going to pay for all this growth? And what will happen if they can’t?” Co-founder Alex Blumberg also announced that Gimlet will no longer be producing top-ranked podcast Mystery Show, but refused from giving details, preferring to say “there are certain things that certainly need to remain private” (runtime 36:18). Vox has background on what appears to have happened after Mystery Show host Starlee Kine lit-up Facebook.
