Who hosts How I Built This?

Could you please clarify who is responsible for producing and presenting the podcast series "How I Built This"? I'm particularly interested in knowing if it's an individual host, a group of hosts, or if it's a network or organization that oversees the show. Additionally, I'd appreciate any details on the background or experience of the host(s), as I'm fascinated by the stories of entrepreneurs and how they got to where they are today. Thank you for your assistance in clarifying this information.
