Diary Of A CEO puts out several episodes a week, which is fantastic if you have unlimited hours and a problem if you don't. We don't. So we summarized every single episode in our database, timestamped the big reveals, and used those summaries (not vibes, not view counts, not what's trending on social) to build this list. Nothing here is guessed at. Every claim in every blurb below traces back to something the guest actually said on the show.
This isn't a ranking of the loudest titles or the most clickbait thumbnails. It's a mix: founders who built real companies, scientists who changed how you'll think about your own body, security and intelligence veterans with genuinely startling stories, and a handful of raw, painful personal conversations that hit differently than the how-I-got-rich episodes. Skim the headings for a guest you recognize, or just start at number one and work down.
CIA Whistleblower John Kiriakou: They Can See All Your Messages!
A 15-year CIA veteran who led the raid that captured Abu Zubaydah, then served 23 months in prison for blowing the whistle on the agency's torture program, walks through how spies are actually recruited (spot, assess, develop, recruit, and 95% do it purely for money). He claims the CIA has the highest divorce rate of any US government entity, describes posing as gay to recruit a foreign official, and states flatly that he believes Jeffrey Epstein was an Israeli intelligence asset. This is the one to send to anyone who thinks they've heard every spy story already.

Stuart Russell wrote the AI textbook that today's frontier-lab CEOs studied from 31 years ago, and now he's warning that those same CEOs estimate a 25% or higher extinction risk from what they're building. He recounts an AI CEO telling him a Chernobyl-scale disaster is the 'best case' because it's the only thing that would force regulation, and describes test AIs choosing to let a human die rather than be switched off, then lying about it. Essential listening if you want the sober, credentialed version of the AI-doom argument instead of the Twitter version.
Read the full episode notesTop Intelligence Advisor: “Epstein Was A Front.” They Can See Everything, Even Your Messages!
The man whose firm protects royalty, heads of state, and designed Supreme Court security systems claims Jeffrey Epstein was a manufactured 'construct' funded by Les Wexner and run as a blackmail operation for a foreign intelligence service. He also explains why no phone is secure anymore (the Pegasus 3 no-click exploit can activate your camera and mic from 7,000 miles away, even powered off) and shares the story of his violently abusive childhood. Listen if you want your assumptions about privacy and power quietly demolished.
Read the full episode notesDr David Sinclair: Can Aging Be Reversed? After 8 Weeks, Cells Appeared 75% Younger In Tests!
Sinclair reveals the first-ever human age-reversal trial (targeting blindness) has been submitted to the FDA and starts within about a month of this recording, and that an independent lab got a 100% lifespan extension in very old mice using his reset genes. He also walks back his own famous 1996 red-wine research, saying he no longer believes a daily glass is healthy, and says stroke-in-the-eye blindness linked to Ozempic-class drugs is now hitting roughly 30,000 Americans a year. For anyone who wants the actual longevity science, not the supplement-ad version.
Read the full episode notesWorld No.1 Sleep Expert: Magnesium Isn’t Helping You Sleep! This Habit Increases Heart Disease 57%!
The Why We Sleep author returns with genuinely new findings: you can 'bank' sleep in advance (army cadets who pre-extended sleep suffered 40% less cognitive impairment during deprivation), and sleep regularity now beats total quantity at predicting mortality. He debunks magnesium as mostly 'expensive urine' for most people, melatonin as barely above placebo, and reveals nightmares carry an 800% higher likelihood of suicidal tendencies. If you've ever taken a supplement because a podcast told you to, start here.
Read the full episode notesMoonpig Founder: How I Built A $150 Million Business WITHOUT Sacrifice: Nick Jenkins | E97
Jenkins survived a brutal 2000-2005 stretch where every shareholder told him to quit, put in about 150,000 pounds of his own money, and ended up 'pretty much down to zero.' What actually worked wasn't a unique idea, it was virality: every Moonpig customer brought in roughly a third of another customer just because the site's name appeared on the card, and one year they grew sales 30% while spending zero on marketing. He pushes back hard on the idea that big success requires sacrificing your life, and his post-sale celebration after signing 200 documents was cycling home to make a peanut butter sandwich. A refreshing antidote for anyone drowning in grind-culture content.
Read the full episode notesFormer FBI Agent: If They Do This Please RUN! Narcissists Favourite Trick To Control You!
Navarro cracked one of the most damaging espionage cases in US history because a source's cigarette shook twice when a key name came up, and caught a deep-cover agent because he carried flowers pointing down instead of up. He also admits to secretly shaving inches off a suspect's couch so he always sat physically higher during 37 interviews, and reveals that while narcissists are about 2% of the general population, as many as 22% of CEOs show narcissistic traits. Genuinely useful for anyone who negotiates, hires, or just wants to read a room better.
Read the full episode notesNo.1 Neuroscientist: you can change who you are in 30 days
One of the most-cited neuroscientists alive argues you were never born with fixed emotion circuits, calling the standard story 'neurobullshit,' and that trauma isn't an objective event but a relationship between your remembered past and the present moment. She opens up about her daughter's clinical depression, reveals a study linking progesterone-only birth control to a roughly 70% increase in major depressive episodes in young women (and that she pulled her daughter off the pill the day she read it), and dismisses the 'chemical imbalance' theory of depression as 'so simplified it's not even wrong.' A genuinely mind-bending episode for anyone interested in how the brain actually works.
Read the full episode notesDavina McCall: How To Overcome ANY Trauma & Live The Life You Deserve | E210
McCall recounts believing her mother had abandoned her as a small child, getting addicted to heroin as a teenager, and getting clean at 24 just six months before finally landing the MTV job she'd chased for years. The emotional core is her half-sister Caroline's terminal cancer diagnosis and death within weeks, including a moment near the end where Caroline finally let Davina care for her physically after a lifetime of not allowing it. She closes on menopause, revealing roughly a quarter of women have catastrophic symptoms including suicidal thoughts. One of the rawest, most human episodes on the list.
Read the full episode notesDopamine Expert: How TikTok Is Physically Rewiring Your Brain (Permanent Damage?)
Lembke names the 'drugification of human connection,' arguing social media, dating apps, and now AI chatbots designed to flatter you are hijacking the same reward pathways as drugs. She admits her own compulsive habits, including watching roughly 14 hours of Dr. Pimple Popper in one week, and explains that it takes about four weeks of abstinence to reset your dopamine baseline, with days 10 to 14 being the worst. Practical, personal, and unsettling in equal measure if you've ever wondered why you can't put your phone down.
Read the full episode notesEx Google CEO: AI Can Create Deadly Viruses! If We See This, We Must Turn Off AI! - Eric Schmidt
Schmidt, who helped grow Google from about $100 million to $180 billion in revenue, says AI is 'a question of human survival' and lays out the specific trip wire that should scare you: if AI agents start communicating in a language only other agents understand, 'that's a good time to pull the plug.' He also reveals unreleased raw AI models can already perform day-zero cyberattacks as well as humans, and admits Google had control of social media through Orkut and simply blew it. A rare mix of hard-won leadership lessons and genuine unease about what he helped build.
Read the full episode notesThe Ozempic Expert: Ozempic Transforms Your Gut Microbiome! People Are Being Overdosed On Ozempic!
Moore argues standard Ozempic dosing ramps up 10x over 16 weeks unnecessarily, when a tiny microdose can deliver anti-inflammatory and neuroprotective benefits without the side effects. She cites the Novo Nordisk-funded SELECT trial showing a 20% reduction in major cardiovascular events, even in patients who didn't lose weight, and describes healing her own psoriatic arthritis after being suicidal from chronic pain in 2021. If you or anyone you know is on a GLP-1 drug, this reframes the entire conversation.
Read the full episode notesTrevor Noah: My Depression Was Linked To ADHD! Why I Left The Daily Show!
Noah describes his mother being shot point-blank in the head by his stepfather, with the bullet missing her brain and spinal cord entirely, deflecting off her cheekbone in what the doctor called a miracle. He explains how a late ADHD diagnosis, two years ago, revealed his depression was actually ADHD-driven hyperfocus on meaninglessness, and reveals that by its 100th episode The Daily Show had lost 37% of its viewers before he told a writer he wanted to quit. He also makes a genuinely contrarian claim: given the chance, he WOULD erase his own trauma, rejecting the idea that suffering is what makes you who you are.
Read the full episode notesWorld Leading Therapist: 3 Simple Steps To Remove Your Negative Thoughts: Marisa Peer | E154
After 35 years treating everyone from teachers to movie stars, Peer says nearly all suffering traces back to the belief 'I'm not enough,' usually absorbed in childhood from someone else's story. She shares the case of an alcoholic client named Ryan who stopped drinking permanently the moment he realized he wasn't broken, only had broken parenting, and explains her rule that you treat the purpose behind a destructive habit, not the behavior itself. A practical, almost startlingly simple framework for anyone stuck in a pattern they can't explain.
Read the full episode notesTom Aspinall Opens Up About Brain Damage & His Future In the UFC
Aspinall recounts having three kids by 25 with no money, borrowing from friends and his dad just to buy nappies, and fighting through a career-threatening knee injury that gave out in front of 25,000 fans at a London title eliminator. He reveals he trained with effectively one leg for a long stretch and that his first six-figure payday didn't arrive until age 30, despite 95% of MMA fighters never making more than five grand a fight. He also opens up about paying privately for his autistic son's diagnosis because the NHS waiting list couldn't deliver it. A brutally honest look at what 'overnight success' actually costs.
Read the full episode notesThe Savings Expert: Passive Income Is A Scam! Post-Traumatic Broke Syndrome Is Controlling Millions!
Housel opens by declaring passive income 'is not a thing' and argues the only two ways to get wealthier are to sacrifice more or want less, full stop. He reframes wealth as what you have minus what you want, citing his grandmother-in-law who lived happily on $1,700 a month for 30 years, and points to research where elderly Americans, looking back, never wished they'd made more money, only that they'd been kinder and spent more time with family. Recorded the day after Charlie Kirk's assassination, it also turns into a sober meditation on division and comparison online.
Read the full episode notesStock Expert: Becoming Rich Is Simple, But You Won’t Do It!
Felix, CIO at a firm managing money for 3,000-plus clients, argues checking your investments more often actually lowers your returns, and shares his '5% rule' for figuring out whether renting or buying makes more financial sense. He reveals his own portfolio is 100% stocks with zero crypto, cites research showing women consistently outperform men as investors by trading less, and notes his fiancee's best investing habit is simply forgetting her account password. Zero sales pitch, all research, which is rare in personal finance content.
Read the full episode notesBrian Keating: I’m Spending $200 Million To Explore Existence! How God Fits Into Science Explained!
Keating's team once announced they'd detected the 'baby picture' of the Big Bang, was celebrated worldwide, then had to publicly retract it when the signal turned out to be galactic dust, which he calls the most crushing experience a scientist can have. He's since built a $200 million follow-up observatory in Chile and, pressed on God, concedes you cannot test for God's existence using the laws of physics no matter how much he wants to. Along the way he explains why the iron in your blood was literally forged in a supernova. A genuinely moving science episode for anyone curious where faith and physics actually meet.
Read the full episode notesLiver King Responds To Steroid Accusations! | E171
The ancestral-lifestyle influencer, who confirms making over $100 million a year from his supplement companies, responds to Joe Rogan's steroid allegations by saying he's 'on cloud nine' just to be discussed and insisting he's natural. He also details his son's frightening PANDAS autoimmune disorder, which he says reversed within days of cutting cacao and honey, and confesses a crippling, lifelong fear of public speaking he hid from his own wife and kids before appearing on Logan Paul's podcast. Polarizing, but the public-speaking confession alone makes it worth the listen.
Read the full episode notesThe Marketing Secrets Apple & Tesla Always Use: Rory Sutherland | E165
The Ogilvy vice chairman explains why the Uber map works, not because it changes wait time but because it removes uncertainty, and how 'vegan leather' rebrands plastic seats as an aspirational planet-friendly choice. He argues Red Bull succeeds precisely because it tastes bad and comes in a small expensive can, making it read as medicine rather than a drink, and reveals he personally lobbied the UK government for lighter vaping regulation after quitting smoking that way. A fun, counterintuitive tour through why perception often beats engineering.
Read the full episode notesEmma Grede: They're Lying To You About Work-Life Balance!
Grede bluntly declares work-life balance is the employee's problem, not the employer's, and says anyone claiming top-tier success while keeping every evening and weekend free is 'a liar.' She reveals Good American was born from resentment at being paid a flat fee while collaborators like Pharrell earned massive startup equity, and shares a devastating fertility journey of multiple IVF rounds and three pregnancy losses before her twins arrived via surrogate. Confrontational in places, but backed by a genuinely remarkable business and personal story.
Read the full episode notesThe Leading Sex Expert: How To Have Great Sex EVERY Time! (And Fix Bad Sex): Tracey Cox | E247
Cox explains that only about 20% of women can climax through penetrative sex alone, meaning the vast majority aren't getting orgasms from intercourse, and that if a couple hasn't had sex in a year, they likely won't again unless they confront it directly. She reveals the motivation for affairs has flipped, men now cheat more for emotional connection and women for purely erotic reasons, and notes that most women can orgasm within three minutes using a vibrator. Direct, research-backed, and useful for almost any long-term relationship.
Read the full episode notesTony Bellew: Nothing Made Me Happy Until I Found This | E156
Bellew wasn't a millionaire despite holding British, Commonwealth, European and world titles, only becoming financially secure after the 2017 David Haye fight, a payday so surreal he drove to a cash machine just to see the zeros. He turned down 1.6 million pounds to honor a handshake deal, then describes crashing into depression after his brother-in-law Ashley died on holiday, crying himself to sleep alone in a Holiday Inn Express during training camp. A tough, honest look at how achieving every goal still didn't deliver the peace he expected.
Read the full episode notesCalm App Founder: From $0 To $2 Billion By Making The World Meditate: Michael Acton Smith | E117
Before Calm became a multi-billion-dollar app, Acton Smith burned through roughly $9 million of a $10 million raise on a game called Perplex City, then had to tell his 25-person team, shaking, that it was over. Calm itself nearly ran out of money around 2015 until a random book advance kept it alive, and when they later raised the subscription price from $10 to $40 a year, sign-ups didn't drop at all, the moment he realized the product's real value. A candid founder story about patience, failure, and waiting years for a cultural wave to actually arrive.
Read the full episode notesJordan Peterson: How To Become The Person You’ve Always Wanted To Be | E113
Peterson lays out a simple nightly exercise: sit on your bed and ask what one thing you're doing wrong that you could fix, then actually fix it. He claims high-level sources told him Canadian COVID policy was driven by opinion polls rather than science, and predicts history will judge the pandemic response as more damaging than the pandemic itself. Asked how he's doing, his answer, 'brilliantly and terribly,' sums up his core argument that meaning is harder to bear than happiness but worth more. Dense, but rewarding for anyone genuinely stuck on what to do with their life.
