About David Baszucki

David Baszucki likes to joke that he spent two years after Stanford doing “the worst jobs in the world” before he trusted his gut and followed his curiosity into educational software. After co-founding Knowledge Revolution and building Interactive Physics into a hit lab simulator, he sold the company and took his family on a cross-country RV road trip. Out of that reset came a much bigger bet: a cloud-based, 3D, multiplayer platform where people could build experiences for each other. The first version, DynaBlocks, flopped. The second version, with user creation at the center, became Roblox. Baszucki and a tiny team stuck to a horizontal vision—cloud, multi-device, user-generated, virtual economy—through near-death monetization scares, the rise of Minecraft and Fortnite, and waves of safety and regulatory pressure. Today, as founder and CEO of Roblox, he thinks in decades, not quarters, sees AI as core infrastructure, and talks as much about intuition, safety, and personal re-architecture as he does about sharding and concurrency.

Interview

December 2, 2025

Q

When did you first feel an entrepreneurial instinct in yourself?

Question 1 of 17
David Baszucki

First entrepreneurial feeling came from a small idea: after Stanford a dorm friend suggested window cleaning. My brother and I knocked on doors and washed windows all summer. That was the first time I saw we could spin something up from nothing and make money.

Q

How did you feel right after finishing college and trying to start your career?

Question 2 of 17
David Baszucki

After college I felt lost. School had a clear path; job hunting did not. I had two or three awful jobs and even called my dad about how bad it was. That disappointment later pushed me to stop forcing it and move intuitively toward work I cared about.

Q

What finally helped you move from feeling lost to a clearer direction?

Question 3 of 17
David Baszucki

Time off after bad jobs helped. Apple II and Macintosh were rising, educational software was interesting. Instead of analyzing every option, I decided to enter educational software, following fascination with 3D simulation, physics, and consumer software. That step led directly to Knowledge Revolution and later Roblox.

Q

How did you find and choose your early co-founders like Eric Cassel?

Question 4 of 17
David Baszucki

Co-founders came from serendipity and openness. I wrote the Interactive Physics vision; MacUser reviewed it. Eric Cassel read it, called, flew from Cornell, and joined. I did not run big searches—I shipped, had a vision, and stayed open to people drawn to it, a pattern that repeated.

Q

What is one big lesson you took from building Knowledge Revolution?

Question 5 of 17
David Baszucki

Lesson: deep customer empathy is gold. With educational software we knew users well. Moving into mechanical engineering software was more tech-driven and less connected to our natural strengths. It worked, but taught me to think hard before walking away from a group you truly understand.

Q

Why did you take a long RV road trip with your family after selling the company?

Question 6 of 17
David Baszucki

After selling Knowledge Revolution I needed a reset. We bought a 40-foot RV, towed a car, and drove across Canada and Minnesota with our three kids. I even hosted a short talk radio stint. It was about adventure and clearing my head before the next big bet.

Q

You once used a spreadsheet with nine possible careers. What did you learn from that?

Question 7 of 17
David Baszucki

I once tried to optimize life with a spreadsheet of nine careers and metrics. It was a bad way to choose. For big decisions, pure analysis can trap you; intuition about what fascinates you is better than a perfect grid. That lesson returned whenever I chose between safe options and harder, interesting ones.

Q

How did you decide to shut down DynaBlocks and rebuild it into Roblox?

Question 8 of 17
David Baszucki

DynaBlocks was a small 3D puzzle game with about 100 users that vanished in two weeks. We knew the real vision was multiplayer, cloud-based, with creation and play. We shut it down and spent 9–12 months rebuilding the broader platform, trusting the big vision despite the first failure.

Q

How did you know Roblox had finally hit product–market fit?

Question 9 of 17
David Baszucki

When we launched user creation and self-publishing, with maybe 100–200 users, we saw constant building within hours. Four of us watched the viral pattern we knew from past bumps and recognized product–market fit. Later the full virtual economy triggered the same immediate reaction.

Q

What happened during Roblox’s near-death monetization crisis and how did you solve it?

Question 10 of 17
David Baszucki

In 2007 users grew but dollars per user fell, revenue flat, costs rising. We tried 50 ideas; none fixed it. The answer was building a full virtual economy—currency, creators selling, users buying, cash-outs, better discovery. Once launched, developers saw they could make a living within hours.

Q

How did you deal mentally with big competitors like Minecraft and Fortnite?

Question 11 of 17
David Baszucki

Minecraft and Fortnite exploded and it felt unfair. We leaned on our pipeline: auto-sharding in the cloud, multi-device support, stable APIs, one engine for mobile and PC. We stayed a unified platform instead of splitting engines or running a big first-party game, playing a long-term infrastructure game.

Q

When engagement and safety seem to conflict, which way do you choose?

Question 12 of 17
David Baszucki

We choose safety. Parents, regulators, and we all want kids safe. Assume an 11-year-old just got a phone. Invest in age estimation, filtering, and safety tools even before laws demand it. There may be short-term engagement trade-offs, but long-term it's right and an opportunity.

Q

How do you build a “safety-first” culture inside a large company?

Question 13 of 17
David Baszucki

We architected vertically, not just functionally. Roblox Safety is a dedicated group with product, engineering, and live ops inside it, with headcount you can measure. Adjacent groups touch safety, but having a pure safety team at the executive level makes it real, not just a slide.

Q

What changes did you have to make in yourself to grow from founder to public company CEO?

Question 14 of 17
David Baszucki

I had to re-architect myself. Early on you can yell and push with raw energy; at scale that fails. I became more zen about feedback—pausing before saying 'that will never scale' and delivering it helpfully. I also trust my gut more without over-clamping it with analysis.

Q

How do you see AI changing Roblox as a business and a platform?

Question 15 of 17
David Baszucki

We run hundreds of AI models for safety, search, discovery, and 3D generation. Waves: quiet behind-the-scenes improvements; generative tools letting creators and users build by talking; eventually avatars and assistants. Our advantage is billions of hours of 3D interaction—we never sell the data but use it to make the platform smarter.

Q

Are you worried that AI will replace developers on Roblox?

Question 16 of 17
David Baszucki

I am optimistic. Like the industrial revolution, work changes rather than disappearing. For creators, AI will raise quality and shift the landscape, not create mass unemployment. New work appears—designing systems, stories, economies, communities that AI accelerates. The best developers will lean in and go further.

Q

What is the best leadership advice you carry with you today?

Question 17 of 17
David Baszucki

Best advice is simple: trust your gut. Many people told me that. My best decisions came from intuition I finally listened to, even when harder or riskier. I still look at data and analysis, but I need to say 'this feels right' and commit.
