2025 has already been a landmark year for The Diary of a CEO. Steven Bartlett has continued to push the show into new territory — bigger guests, harder questions, and conversations that feel less like interviews and more like turning points for the audience listening.
We've been tracking every episode at diaryofceo.online, and these are the moments from early 2025 that stopped us in our tracks. Not just good episodes — specific moments within episodes that changed how we think.
One of the most powerful trends in 2025's episodes has been guests — extremely successful guests — admitting they still feel like frauds. In one early January episode, a guest who runs a billion-dollar company paused mid-sentence, collected themselves, and said: "I wake up most mornings convinced today is the day everyone finds out I'm not as smart as they think."
The silence that followed was unlike anything the show has produced. Bartlett didn't rush to fill it. He let the moment breathe. And that restraint — that willingness to let uncomfortable truth hang in the air — is what makes DOAC different from every other business podcast.
Why it matters: If someone running a company worth more than most people will ever see still battles self-doubt, the idea that you need to "fix" your confidence before starting becomes obviously absurd.
While most tech podcasts in 2025 have been breathlessly optimistic about AI, one of Bartlett's early-year tech conversations took a different turn. The guest — a founder deeply embedded in the AI space — laid out a framework for thinking about which jobs AI will actually replace versus which ones it will augment.
"Everyone's asking 'Will AI take my job?' The better question is 'Which parts of my job are pattern-matching, and which parts require genuine human judgment?' Automate the first. Double down on the second."
The conversation went further into how young people should be thinking about career planning in an AI-first world — not by avoiding technology, but by developing skills that compound with it rather than compete against it.
Why it matters: This was practical, actionable career advice at a time when most AI discourse is either utopian or apocalyptic. The middle ground — nuanced, specific, and grounded — is exactly what people need.
Bartlett has always been open about his personal life, but a 2025 solo segment saw him revisit things he'd said in earlier seasons about relationships and admit he was wrong. Specifically, the idea that romantic relationships are a "distraction" from business success.
"I used to say you had to choose — love or ambition. I was 25 and stupid. The truth is that the right relationship doesn't drain your energy. It multiplies it. I was just choosing the wrong relationships and blaming the concept."
This moment resonated massively with the audience because it modelled something rare in the creator economy: publicly updating your beliefs. Most influencers double down on old takes. Bartlett threw his old take in the bin and explained exactly why.
Health episodes on DOAC have always been popular, but a 2025 conversation with a leading longevity researcher produced a moment that reportedly led thousands of listeners to book blood tests within 48 hours of the episode dropping.
The guest explained, in simple terms, that most people are walking around with undiagnosed deficiencies — vitamin D, B12, magnesium — that directly affect energy, mood, and cognitive function. But the moment that cut through was this:
"You wouldn't drive your car for five years without checking the oil. But most people go decades without a basic blood panel. You're running a biological machine on hope."
Why it matters: Health advice on podcasts rarely translates to action. This episode did, because the guest gave a specific, low-cost, immediate next step — not a lifestyle overhaul, but a single appointment.
An entrepreneur who'd built and lost a £50M company came on the show in February 2025 and delivered what many listeners are calling the best business education in a single episode. Rather than a success story, they walked through their failure in forensic detail:
The level of specificity was extraordinary. This wasn't vague "I failed and learned from it" content. This was a post-mortem with timestamps, numbers, and named decisions. The kind of case study business schools charge thousands for, delivered free on a podcast.
If you've been listening to DOAC since the early days, 2025 feels like a gear change. Three things stand out:
Based on Bartlett's hints on social media and guest patterns, we're anticipating several major conversations later this year. Without spoiling anything, the show seems to be moving toward more long-form, multi-part episodes with guests who've traditionally avoided podcasts.
We'll be tracking every episode and updating this list at diaryofceo.online as the year progresses.
