| Chapter | Topic | Harry as informed peer | Guest teaching | Guest disagreement | Harry pushing back | Why |
|---|---|---|---|---|---|---|
| Anthropic eating OpenAI's Lunch? The Enterprise Zeitgeist Shift | 3 | 4 | 2 | 1 | Harry introduces the Ramp dataset showing Anthropic capturing spending, but Rory immediately corrects him on the nuance between total spend versus new marginal spend. The guests then dominate the discussion with detailed analysis of developer workflows and token economics. | |
| SpaceX's $2 Trillion Valuation and Elon's Space Data Centers | 2 | 3 | 3 | 2 | Harry references SpaceX reaching a $2 trillion valuation based on news reports, but Rory forcefully pushes back against attributing market signaling to prediction markets like Polymarket rather than actual stock movements. Harry briefly defends his premise before letting the guests analyze Elon's execution probability. | |
| Jeff Bezos's $100B AI Manufacturing Bet & the Billionaire Refuge | 2 | 2 | 2 | 1 | Harry introduces Jeff Bezos's $100B manufacturing fund and prompts the guests on how to evaluate late-career billionaire bets. The segment turns into a collaborative thesis on Miami billionaire dynamics and political environments. | |
| Groq's $20 Billion Nvidia Acquisition & Tax Inefficiencies | 2 | 4 | 3 | 1 | Harry brings detailed deal facts regarding Groq's acquisition by Nvidia, but Rory playfully calls him out for routinely ignoring his own prepared show notes.

| Figma's Valuation Drop and the Reality of AI Disruption | 3 | 5 | 3 | 2 | Harry shares personal financial exposure to Figma and quotes an interview with Figma's CRO about sales hiring and pricing.

| The Math of Series A: Why You Need a $1 Billion Fund | 6 | 6 | 5 | 4 | Harry presents a firm thesis on why modern Series A funds require at least $1 billion in capital due to check size inflation. Rory explicitly corrects Harry on how fund reserve math operates, leading to a sharp banter exchange over venture fund math. | |
| The Late-Stage Exit Crisis & Momentum vs. Shrewd Investing | 5 | 5 | 4 | 5 | Harry pushes back against Rory's praise of disciplined investors, arguing that momentum players stole AUM and achieved quick markups while disciplined investors missed out. Rory responds by telling Harry to look in the mirror. |
Statements from this episode (27)
O'Driscoll: Short software products that fail to realize AI disruption
“If you're a software product and you don't think AI is going to disrupt not just how you build, but what you build, Then you actually probably want to actively short it.”
Lemkin: Ratio of acquirers to unicorns is at career low
“I just worry there's some ratio of potential acquirers divided by unicorns, and I think we're at the lowest ratio of our careers.”
Lemkin: Hyperscalers will not buy existing unicorns
“I just don't believe the hyperscalers are going to buy these companies.”
O'Driscoll: Ramp data shows Anthropic grabbed 73% of new AI spend
“Just to start with the facts, they actually said 73% of new spending. Right. And what it is, and the same graph shows OpenAI is still actually ahead of Anthropic in terms of total spend. But the marginal buyer in the last six weeks, eight, 10 weeks has massive…”
O'Driscoll: OpenAI can still exit as largest standalone model player
“I mean, they're doing finally the right stuff, you know, perhaps a year, year and a half later, but it's still clear to me that if you just take a big deep breath and you are running that organization, focus on the two or three things, get a little more sensib…”
Lemkin: SaaStr will not switch internal AI apps from Claude to OpenAI
“It runs on Sonnet three. I mean sorry, four, seven, and maybe a little bit of Opus. There is no way we're going to switch the model. This is dialed in. It works. Now we're going to have to deal with QA when it goes to four, eight and five. There's a little bit…”
Lemkin: High-value enterprise AI apps are insensitive to token pricing
“There are so many applications like the ones I described that were not that sensitive to token costs. If you use 204 102,000 dollars, 10,000 dollars of tokens for a month for these, it just doesn't matter. And so there's the open router world where costs are s…”
O'Driscoll: AI coding apps spend 40-50% of revenue on tokens
“There's a ton of really interesting apps that, you know, for five, seven, eight percent of revenue on tokens are building huge value, which my sense at least is very different than the coding apps where you might be at 40 or 50%.”
O'Driscoll: Polymarket pricing gave SpaceX a 50-60% chance at $2T IPO
“Polymarket said the probability of SpaceX being worth two trillion dollars on the IPO went up to 50, 60%, right? From a lower number, right?”
O'Driscoll: Markets won't sustain a $400B valuation bump from Musk's fab announcement
“I am significantly more skeptical That six months from now, people are going to attribute another 400 billion of value to a statement that I'm going to build a fab.”
Lemkin: SoftBank is hitting debt limits and flashing above covenants
“The only problem is SoftBank seems tapped out. They're hitting their debt limits. They just announced this week, right? That they're flashing above their covenants.”
Lemkin: Sergey Brin has left Mountain View and will not return
“He's gone. He ain't coming back except for staff meetings and hackathons in, in Mountain View. He's gone.”
Lemkin: New York QSBS tax policy will not prevent founder exodus
“I really don't think adding QSBS to New York is going to lead to the exodus that the people wanted to do. We can talk about why, but they did it in California and that alone didn't work.”
Lemkin: Odds Google builds a long-term Figma competitor approach zero
“I think the odds that they desire, decide to build a Figma competitor from this for a decade approach zero.”
Lemkin: Figma Make is one of the worst products used recently
“Figma Make is one of the worst products I've used in the last six months”
Lemkin: Refuses to buy Figma stock at $12B valuation
“No, I don't see any evidence of turning, of these agentic investments working. I would rather miss, miss out on the bounce right off the hard deck than invest in something that may fall below it.”
Lemkin: Legacy public SaaS companies are in terminal decline over AI
“Very few public companies can effectively monetize AI, and that's why they're all in terminal decline. Almost all of them at the moment are in terminal decline.”
Lemkin: Core AI products must drive 50% or higher ARPU growth
“Is your ARPU 50% or higher than it was pre-AI? It's a really simple test. Can you drive ARPU up 50% or more? It's very different at Salesforce or ServiceNow. It appears that Notion has done that, in which case they passed the test, right? But I want to see 50%…”
Lemkin: Slack will achieve Notion-like ARPU growth from AI in 2026
“I suspect as the year goes on, we're gonna see the same thing at Slack, because most folks haven't used it, we're on it. The AI version of Slack for certain use cases is so much better. I don't love that they're not just charging another four bucks a month, bu…”
Stebbings: VC firms need at least $1B to compete in Series A
“My takeaway is, honestly, you can't do early, and you're going to kill me, Rory, with less than a billion if you're going to compete to lead A's.”
O'Driscoll: Scale Venture Partners maintains a 50% fund reserve ratio
“We, you know, over like six or seven funds, we've been 50% reserve.”
O'Driscoll: Series A returns derive from the initial check, not follow-ons
“For that kind of Series A game, the Series A is not, for us, especially for a firm that just has, you know, checks for A's and B's and of this size, it's not an option value on putting a ton of money in later. Most of your value is made on that first check.”
Lemkin: Seed ownership will increasingly dilute to 3-4% at exit
“I think we're going to see more and more of those. Right. Dilution in time. We'll see more and more seed investments eroded to three, four percent.”
Lemkin: VCs backing late-stage AI startups below Anthropic face zero exits
“So many folks sub-anthropic are going to get their arses burned because they'll end up in the dead zone. They'll have great companies without great IPOs and zero M and A opportunities.”
O'Driscoll: Capping Scale's entry valuations under $400M was the wrong play
“We haven't done deals with a billion dollars, but we kept it in a 100 to three, four hundred million dollar pre-money valuation, and right now that's been the wrong play, just to put it out there, right?”
Stebbings: 20VC's biggest regret was not playing momentum in hot AI rounds
“My biggest regret with our Series A fund is not being more elastic, disregarding the Series A mandate, and just saying I'm going to leverage the brand and the access that I have, arrogantly, forgive me for that, to get into super hot companies like your 11 Lab…”
