Alex Cooper made "mistakes in terms of trusting people" at the start of her career.

The 30-year-old Call Her Daddy host has opened up about building her multimillion-dollar Unwell media empire, admitting that her early days in the industry came with a steep learning curve.

Appearing on Phoebe Gates and Sophia Kianni's The Burnouts podcast, Alex said: "I wish I would have put more things in writing so that I could back up what really happened.

"It's so crazy how much emotion can get tied into business. As much as everyone's like, it's business, it's not personal -- everyone takes it f****** personal, especially if it is your own company or your brand."

The media mogul recalled being caught off guard when people misrepresented conversations she had with them in good faith.

She explained: "Some of my missteps in business came when I was being honest with someone, who would then turn it around and say I had done something entirely different. And I'm like, 'Wait, that never happened.' I guess I technically should have put that in writing -- so I think now I put everything in writing."

Alex also pulled back the curtain on the inner workings of her landmark $60 million Spotify deal, signed in 2021, revealing she'd initially been offered a comparable deal with Amazon but turned it down.

Alex recalled: "To be honest, it was the same amount of money basically and a little less work. So I was like, why would I not do Spotify?"

The Spotify arrangement -- 52 episodes a year with a guaranteed monthly income and no download targets -- was easy to "wrap her head around".

Alex admitted she was "so green" when she signed the deal, recalling her confusion at discovering her agents at United Talent Agency received the Spotify payments first before passing on her share.

She said: "I was like, 'Wait, no, I want that in my bank account. And then I'll send your 10 percent.'"
