Transcription

Chapter 1: What inspired Vlad Tenev to create Robinhood?

2.107 - 22.613 Unknown

Tetragrammaton.

0

23.273 - 46.417 Vlad Tenev

I was at this party in San Francisco in I think it was early 2012. And this was still when we were running our second business, the software business selling the picks and shovels to hedge funds. And I was explaining to this person at the party what we were doing. In San Francisco, a lot of people are, you know, tell me about your startup sort of thing.

0

46.918 - 63.95 Vlad Tenev

I was like, okay, well, we have this technology. It's really fast. Back then we weren't competing on cost, but it was all about latency. Like how quickly can you take a signal from the market, be able to interpret it and spit out a trade in response. And we were talking microseconds here.

Chapter 2: How did Robinhood change the landscape of stock trading?

64.171 - 84.903 Vlad Tenev

So you take the signal. Michael Lewis wrote a book about this. He did, yes. And that book caused a lot of problems for me later on. Yeah, because that book was published right when Robinhood was announced and launched. Effectively, I was telling this person about my business. And we have these customers that are using our software.

0

85.284 - 94.176 Vlad Tenev

They're trading billions of dollars per day in volume with a small team of people. And it's really fast. And by the way, it's very efficient.

0

Chapter 3: What challenges did Robinhood face during its early days?

94.216 - 117.402 Vlad Tenev

They pay next to nothing, right? And this guy was like, So you're telling me these customers, three or four of them that you have, trade tens of billions of dollars a day and they pay next to nothing. Why can't I have that? You know, I have my Schwab account. They're charging me, I don't know, $10, $20 a trade. Can I use your software? And at first I was kind of like, that's ridiculous.

0

117.882 - 120.265 Vlad Tenev

You can't use the software. You have to be a developer.

0

Chapter 4: How did the financial crisis influence Robinhood's founding?

120.325 - 151.597 Vlad Tenev

It's, you know, for institutional customers. But then I get to thinking, and I call my partner who is in New York on a sales trip. The question was, can we go after retail? Is there a retail product here? And this guy's right. All of the big discount brokerages are charging $10 a trade. And we kind of knew how everything worked full stack, how you can connect to the market.

0

151.657 - 157.808 Unknown

They're also kind of antiquated for young people. I don't think they thought about opening one of those accounts.

0

158.469 - 160.052 Vlad Tenev

Yeah, absolutely not.

0

Chapter 5: What role did technology play in Robinhood's success?

160.352 - 182.115 Vlad Tenev

And they had high minimums. Most of them would require $2,000 before opening an account. Nobody had mobile apps. So we started thinking, we're like, well, is there some reason why you can do this for really cheap on the institutional side, but not on the retail side? Are there additional rules and regulations? And we got deeper and deeper and deeper.

0

183.715 - 197.45 Vlad Tenev

and we just realized there's no fundamental reason. It's just no one had done it. Nobody had done it, and it was kind of a new thing. I mean, every 10 or 20 years, someone comes and tries, right?

0

Chapter 6: How does Robinhood approach user experience and accessibility?

197.47 - 225.214 Vlad Tenev

But it's not very many people were trying. As a matter of fact, E-Trade, which was kind of a disruptor in a similar vein to Robinhood, started in the 80s in Palo Alto, California, oddly enough. with these two older guys. One of them was like a business guy, and the other one was an engineer. And the business guy, I think he was in his 60s or 70s, this guy Bill Porter, had just gotten a Macintosh.

0

226.136 - 251.856 Vlad Tenev

And his idea was, I love my Macintosh, it would be really cool to be able to trade stocks on it. And that was kind of the genesis behind E-Trade, which became the dominant sort of like .com first online broker. So yeah, every 10 or 20 years, something happens where the right people kind of get together and create something. My college best friend and I, we bonded over physics.

0

252.137 - 254.259 Vlad Tenev

So we both came to Stanford to study physics.

0

Chapter 7: What are the future plans for Robinhood's services?

254.459 - 276.12 Vlad Tenev

We both met in the physics department as physics majors. And we would challenge ourselves by taking all the graduate classes. And so we really bonded doing these late nights in the physics building, banging our head against the wall, trying to solve these like super difficult problems. Were they all problems that were already solved? Yeah, yeah.

0

276.24 - 297.056 Vlad Tenev

It was like, you know, homework problems, things like that. Not unsolved novel research, at least at that point. And then we both transitioned to math at the same time because... Stanford physics department was geared towards creating experimentalists. and I experienced experimental physics.

0

Chapter 8: How has going public impacted Robinhood's operations?

297.116 - 323.376 Vlad Tenev

And these are the people that are like working on the massive colliders and it's basically like a industrial scale project, right? And what appealed to me was one person, one mind sitting on a couch, lying down, maybe with a chalkboard and just taking 100% of your mental energy and creating an insight or a novel idea. That's what I really loved about physics.

0

323.356 - 347.463 Vlad Tenev

And it turned out that the purest way to capture that is math. And I wasn't as interested in like the laboratory work, doing like electronics. So you like the theoretical side. I like the theoretical side. And Stanford was much more towards creating experimentalists. They had some good theorists, but if you wanted to get too theoretical, they sort of sent you to the math department.

0

348.164 - 378.085 Vlad Tenev

But yeah, so my co-founder and I we transitioned to math. And then when we graduated, he was one year older than me, he stayed to get his master's in math. And then when I graduated, it was kind of like, what are we going to do next? So I went down to UCLA to get my PhD. And he got a job in finance, kind of on a whim, at this hedge fund up in Marin County, just north of San Francisco.

0

378.622 - 407.592 Vlad Tenev

his first month on the job, my first month in grad school, Lehman Brothers blew up. And so this was the start of the global financial crisis. 2008? 2008, fall of 2008. And sort of in the wake of this global financial crisis, we decide to start our own financial company. He kind of pulls me into it, right? I was a little bit skeptical, but I wasn't having that much fun in my PhD program.

0

408.353 - 431.46 Vlad Tenev

I think my first year in my PhD program, it sort of hit me like a ton of bricks that I entered into math with pure intentions and to be creative, but like this was a career. I was signing up for a career and the aspects of the career that I was confronted with were really not that attractive.

431.592 - 435.799 Unknown

So would you say the financial collapse was an opportunity? It was a huge opportunity.

436.36 - 453.932 Vlad Tenev

But the first opportunity, we didn't get the idea for Robinhood. It was really just, there's a lot of volatility. We can trade for ourselves, create our own trading algorithms, our own hedge fund to capitalize on that. And so that was the first business. And that didn't work out very well.

454.253 - 459.061 Unknown

Are most of the people involved in that world super brilliant mathematicians or not necessarily?

459.441 - 478.592 Vlad Tenev

So at that time, there was a bit of a changing of the guard. So in the old days, institutional trading was run by these big banks, you know, the Goldman Sachs, JP Morgans, they would have institutional trading desks. You imagine like a sea of people on phones.
