A lot of companies have ambassadors, spokespeople, and other influential, external contacts for the brand. That can be a great audience to tap into for a branded company podcast, like the United Nations is doing in their show:

Awake At Night

Host Melissa Fleming talks to the diverse set of UN representatives - I’m not exaggerating, the guests include an “advisor”, “envoy”, “coordinator, “under-secretary-general”, “advocate”, and “rapporteur” (which means a person appointed by an organization to report on the proceedings of its meetings).

It’s a great showcase for the amazing people involved in the work of the UN across the globe. I listened to the episode “Saving Seas, One Swim at a Time”, which highlighted advocacy work for healthy oceans through long-distance, cold-water swimming.
