What's the right age to start a company?

VC has a DiCaprio problem.

Leo just turned 50. The upper age of his girlfriends is usually 25. But they keep getting younger, while he gets older. The gap widens every year.

Venture has developed a parallel pattern, but with founders instead of girlfriends. VC partners get grayer but the founders stay the same age. Real pitch, real cap table, and a founder who cannot legally order a drink. I have a rule about this. If you can't sit across from me at a closing dinner and order a beer, I'm probably not your investor.

But VC swings hard in the other direction too. Our industry loves the seasoned operator. Someone who has spent two decades in the trenches, built and exited companies, and earned the kind of credibility that makes investors feel safe. That's the comfortable bet, and capital flows there easily. Marc Lore is a great example. Started Diapers.com, then Jet.com, now working on Wonder, and money will flow to him regardless of what he does next. It also doesn’t hurt that he’s already a billionaire. Ravi Gupta is someone else who comes to mind. Longtime operator, Instacart COO, crushing it at Sequoia, making a comfortable salary every year. He recently left to build Ithaca Holdings, a billion-dollar acquisition vehicle, with a former Meta exec. Why does he need to leave to start a company? Because he's that excited. And he's far from alone. Everyone's going back to building right now.

The venture industry loves a barbell: back the 18-year-old prodigy or back the 45-year-old executive with a Rolex and a Rolodex. The middle is quieter than it should be. This isn't about who can build a great company (any age can). It's about where venture is leaving money on the table. The founders in their late 20s and early 30s have real professional scars and came of age with AI already in the mix, and they're getting overlooked in a market that loves a headline at either end.

📈 Built for This Moment

I think too often, we forget who actually builds the defining companies of each technology wave. And more importantly, we forget that each wave has a different age band, because each wave requires a different kind of founder.

PC: late teens to mid-twenties. Bill Gates was 19 when he founded Microsoft. Steve Jobs was 21 and Steve Wozniak was 25 when they started Apple. Michael Dell was 19 when he started Dell out of his dorm room. The barrier was purely technical. Build great technology and the product sold itself.

Internet: mid-twenties to early thirties. Jeff Bezos was 30 when he started Amazon. Larry Page and Sergey Brin were 25 when they founded Google. Jerry Yang was 26 when he co-founded Yahoo. Elon Musk was 28, Peter Thiel was 31, and Max Levchin was 23 when they built PayPal. Technical skill alone wasn't enough anymore. You needed business instinct and credibility.

Mobile and social: late twenties to mid-thirties. Brian Chesky was 27 when he founded Airbnb. Kevin Systrom was 27 when he launched Instagram. Jack Dorsey was 30 when he co-founded Twitter. Travis Kalanick was 33 when he started Uber. The two outliers, Mark Zuckerberg at 19 and Evan Spiegel at 21, got a lot of media attention mostly because of their age. Both also struggled publicly with the demands of scaling before they had the leadership experience to match. This wave rewarded founders who understood distribution, network effects, and how to build teams that could grow as fast as the product.

Cloud and enterprise: mid-thirties. Marc Benioff was 35 when he founded Salesforce after 13 years at Oracle. Alex Karp was 36 when he co-founded Palantir with CIA backing through In-Q-Tel. Stewart Butterfield was 36 when he started Slack. You needed the trust of Fortune 500 companies. Top-down sales cycles. Deep enterprise relationships. It's infinitely harder to walk into those rooms at 22.

Each wave demanded a different skill set, and the age band shifted accordingly. Now AI is rewriting the rules again. Software is commoditized. The technical moat that used to take years to build can be replicated in weeks. The differentiator is shifting toward distribution, leadership, and speed of execution.

Every major tech wave has been owned by a specific age band. AI is no different. There's a generation best positioned to win this one, and I have a thesis on which one it is.

👶 Gen Alpha and Baby Gen Z (Under ~25)

The self-taught internet native who has been shipping since middle school.

Of course, this cohort is more AI native than any other. They grew up inside these tools. They’re also fearless, and sometimes that fearlessness is exactly what a market rewards.

But these kinds of founders also have a habit of imploding their companies, and it almost always traces back to leadership. You can only get these reps by logging time inside organizations, and most of this cohort hasn't done that yet. How to navigate a cofounder conflict before it becomes existential only comes from years of experience, and no amount of AI fluency can shortcut that. The founder who has literally never had a work experience other than a singular internship and claims to know everything: I've sat across from that person dozens of times now.

The result is founders who can ship fast but struggle to scale. And at pre-seed, those two things look identical, right up until they don't.

⚡️ Zillennials aka Older Gen Z/Younger Millennials (~26-35) 

Old enough to have professional scar tissue, young enough to have adopted AI without fighting their own habits.

ChatGPT launched in October 2022. This cohort was 22 to 31 at that moment. They were in their first or second real job, still forming their professional muscle memory, and AI was part of that from the start. Their habits were still being shaped, and AI shaped them. That’s different from every other cohort.

There's something else worth naming here. Einstein published four of his most groundbreaking theories at 26. There's a well-documented pattern where people do some of their greatest work in their mid-to-late twenties, old enough to have built real skill, young enough to still be naive about what's supposed to be impossible. Some people call 26 the miracle year. I think that applies directly to what we're seeing right now.

Two founders in our portfolio come to mind. One spent roughly a decade building, scaling, and eventually selling a startup. Now they're back with something AI-native, and the difference is clear in every decision they make. They've rethought how they want to raise and know exactly who they need around them. And they're still young enough that the all-consuming early stage grind fits their life. 

The other held senior operating roles at two different companies, including a COO seat at a multi-billion dollar one, and led 0-to-1 scaling at both. Now they're building their own thing for the first time, and the operational instincts are there. When I look at who we've actually backed at Park Rangers, it keeps being this profile. Maybe that's partly a function of my own age, so I should be transparent about that. But I think there's more to it.

These founders are sometimes underestimated, which cuts both ways. They get overlooked in favor of flashier 20-year-old prodigies and more credentialed 40-year-old operators. But underestimation also gives them room to operate without the pressure that comes with being the hot demographic. The 29-year-old with five years of growth marketing experience who just built an AI product doing $100K MRR three months in deserves more attention than they're getting.

I've spent the last several years thinking about exactly this cohort. I even hosted a podcast called Dear Twentysomething, where I recorded 100+ episodes interviewing people about what their 20s were actually for, what they were building, what they were afraid of, etc. I've always been a little obsessed with how decades define us, especially in those early career years when you're still figuring out who you are and what you're capable of.

💼 Millennials, Gen X, and Beyond (~36+)

The seasoned operator with a track record investors love.

Sam Altman is 40. Dario Amodei is 42. Bret Taylor is 45. The biggest names in AI right now are all in this cohort, and every VC in the world would write them a check tomorrow. That's the point. This is the proven bet. The founder who has already done it, already earned the credibility, already built the network that makes fundraising feel like a formality. 

But the opportunity cost of starting from scratch at this stage of life is the highest it's ever been. And their professional habits were fully formed before AI arrived. There was existing muscle memory to override, and that's a real friction point when speed matters most.

Nobody needs to be convinced to bet on this cohort. Capital already flows here.

🎯 The Overlooked Bet

So who is venture sleeping on? The Zillennials. Mid-twenties to mid-thirties. Old enough to lead. Young enough to still be building their first real thing. At exactly the right age when the tools got good enough to matter. That’s the bet.

At Park Rangers Capital, we're not solely betting on the VC barbell. We're spending more time in the blind spot.
