About this episode

Qasar Younis is the co-founder and CEO of Applied Intuition, a $15 billion AI company that adds intelligence to cars, tractors, planes, submarines, and other vehicles—essentially, Tesla or Waymo without the hardware. He was previously COO of Y Combinator, started his career as an engineer at GM and Bosch, and was born on a farm in Pakistan. We discuss: 1. Why the biggest AI revolution will play out in mining, farming, construction, and trucking over the next 5 to 10 years, not in software 2. Why Qasar intentionally stayed under the radar for nearly a decade while building Applied Intuition, and why most founders shouldn’t do that 3. The truth about China’s AI capabilities and why comparisons to American companies are fundamentally flawed 4. The company values that drive Applied Intuition: speed above everything, laugh a lot, half the work is follow-up, never disappoint the customer 5. The biggest lessons from Qasar’s stint as YC’s COO, including that the most successful companies show traction very early 6.

Episode summary

You’ve been quietly building Applied Intuition into a $15 billion force that puts AI into cars, tractors, planes, subs, and heavy equipment, with nearly every major automaker and even the Department of Defense on your customer list. If this all goes right, what does the near future with physical AI feel like?

Think Industrial Revolution energy, but aimed at abundance and access; AI lowers suffering by personalizing help, speeding discovery, and widening mobility for people who can’t drive or afford a car. Physical AI will make transport cheap and safe, bring services closer to those far from care, and chip away at problems we once thought impossible.

People are anxious about AI, jobs, and those viral robot clips; markets are wobbling too. How do you stay optimistic, and what should listeners do right now?

Fear fades with understanding; learn how the systems work and you’ll spot hard limits behind flashy demos. Also separate societal anxiety from stock moves—some investors are reacting to surface-level prototypes and mispricing risk, which isn’t the same as a real product moat collapsing.

Self‑driving is just robots on wheels, and when it fails it’s already dangerous. How safe can this get?

Autonomy already outperforms many human drivers, and in a few decades we’ll see human-only driving as reckless given the tens of thousands of annual road deaths. In trucking and other hazardous work, a bit of intelligence prevents crashes and saves lives.

On hardware, how close are we to robots helping us day to day?

They’re here in narrow forms; the leap is versatile agents that handle many chores with light guidance, which can come fast once enabling hardware becomes cheap and ubiquitous. Expect the biggest gains first by adding intelligence to existing machines—cars, mining trucks, and construction gear—where the mechanical platform is mature and the ROI is obvious.

Over the next five to seven years, two tracks scale worldwide: lower‑cost L2‑plus systems (light sensors, no HD maps) and geo‑bound L4 (heavier sensors and compute). As autonomy shifts from a pricey option to nearly standard, accidents and injuries fall, and this pattern repeats across farming, mining, logistics, and defense.

Listeners fear AI will take their jobs, but there’s also a view it arrives just in time for aging workforces and shrinking populations. Where do you land?

These industries need autonomy now—fewer people want grueling, dangerous roles, and the average farmer is near retirement. Slamming the brakes on frontier tech would stall growth and hurt the most vulnerable; the better path is to push forward and cushion transitions.

How do you see the China question and clips like those nunchuck robots?

Don’t compare state‑aligned entities one‑to‑one with Western firms; goals, incentives, and sustainability differ. Admire the research, but judge outcomes like unit economics honestly, and avoid zero‑sum thinking while acknowledging the systems aren’t equivalent.

You stayed quiet for years, then your first tweet blew up; most founders are told to build in public. Why did you go under the radar, and why speak up now?

Radical pragmatism—time spent posting is time not spent on product and customers, and we preferred Berkshire‑style focus over hype. As stakes grew, mentors pushed me to share ideas that matter beyond our company, so I’m using visibility as a tool, not a lifestyle.

You’ve said great companies show early pull; what should founders without traction do?

If two years in the market isn’t steering you toward a sharper path, consider a hard reset—co‑founders, space, or even your own capacity may be off. Treat your first three years as craft training; many winners are on a second or third try.

Share the operating values that actually drive Applied.

We codified what worked: move fast and safely, never disappoint customers, prize technical mastery and high output, and remember that half the job is follow‑up. We also protect sanity—laugh a lot—and we believe our best work happens quietly without fanfare.

You talk a lot about maintenance and craft.

Operational excellence is mostly quality, safety, and upkeep—think automotive factories turning out a car every half minute. That’s why we have cleaning zen, no‑shoe spaces, and a bias toward fiscal discipline; caring for the system yields clean code and durable businesses.

You also push broad, deep reading over hot takes; what’s the philosophy and a few standouts?

Read widely and old to increase signal, then map those ideas to your work; a well‑rounded leader makes better calls. Recent and evergreen picks include The Emperor of All Maladies, Made in America, Guns, Germs, and Steel, SPQR, and the Autobiography of Malcolm X.

How do you build a culture where the best idea wins and emotion doesn’t derail decisions?

Invite inputs from customers, competitors, and every level of the team, and reward people for speaking up; then decide quickly and adjust when the market shifts. Momentum blinds companies—Google vs. early Facebook is a lesson—so we prize decisiveness and course‑correct without ego.

On emotions and AGI, some argue feelings unlock consciousness; how do you square that with running a company?

Human thought is richer than pure input‑output, but in product decisions emotions often distort judgment, so strip the filter and aim for consistent reasoning. Leaders still have to be right, which means building a sustainable, standalone business.

Spicy closer: many CEOs here don’t have great taste—why?

Narrow life experience dulls judgment; if you’ve never been at the bottom of a huge org or out in the world, you miss what good feels like for real people. Broaden your inputs—jobs, travel, art, history—and your taste, and your decisions, get sharper.

This was a blast. Where can people find you and be helpful?

Send me book recommendations and non‑obvious research, especially around physical AI in mines, farms, construction, and trucking. I’m on Twitter now and always open to thoughtful takes.
