Believe it or not, the guy you see on X (formerly Twitter) every single day didn't actually start Tesla. Honestly, if you ask the average person on the street "who made Tesla motors," they’ll shout "Elon Musk!" before you even finish the sentence. But they’d be wrong. Well, mostly wrong. It's complicated.
The real story starts in 2003 with two engineers named Martin Eberhard and Marc Tarpenning. These weren't car guys in the traditional sense. They were Silicon Valley veterans who had just sold an e-book company for a small fortune. They were looking for their next "big thing," and they happened to notice something weird in the driveways of Palo Alto.

Wealthy people were buying Toyota Priuses.
Now, a Prius in 2003 wasn't exactly a status symbol. It was a statement. These people had Porsches and BMWs, but they were driving the Prius to show they cared about the planet. Eberhard and Tarpenning realized there was a massive, untapped market for a car that was green but also, you know, actually cool. They wanted to build a "technology company that happens to make cars."
The Original Architects You’ve Probably Never Heard Of
Martin Eberhard was the first CEO. Marc Tarpenning was the CFO. They incorporated Tesla Motors on July 1, 2003. Why Tesla? Because of Nikola Tesla, the genius who basically invented the AC motor. They didn't have a factory. They didn't have a car. They just had a vision: use lithium-ion batteries—the same stuff in your laptop—to power a sports car.
At the time, the big car companies in Detroit thought this was hilarious. General Motors had just crushed their own electric car program, the EV1, literally sending the cars to the crusher. They "knew" electric cars were golf carts. Boring. Slow. Ugly.
Eberhard and Tarpenning didn't care. They hired a guy named Ian Wright, an Australian engineer who became the third employee. Then they went looking for money. They needed millions, and most venture capitalists laughed them out of the room. Building a car company is a great way to turn a large fortune into a small one.
Enter Elon Musk: The Investor Who Rebranded Everything
In early 2004, the trio met Elon Musk. He had just made $176 million from the sale of PayPal to eBay. He was already starting SpaceX, but he was obsessed with electric flight and cars. He put in $6.5 million of his own money, becoming the lead investor and Chairman of the Board.
Shortly after, JB Straubel joined as the fifth employee. Straubel is often called the "secret weapon" of Tesla. He was the one who actually figured out how to keep thousands of laptop batteries from exploding when you put them in a car chassis.
So, who made Tesla motors? For years, this was the subject of a massive, ugly legal battle. In 2007, things went south. Production of the first car, the Roadster, was a disaster. It was way over budget and years late. Musk, who was the Chairman, basically staged a coup. He pushed Eberhard out of the CEO chair.
It got nasty. Eberhard eventually sued Musk for libel and slander. He claimed Musk was trying to rewrite history to make it seem like he was the sole founder. In 2009, they reached a settlement. The result? A legal agreement that five people can officially call themselves "co-founders":
- Martin Eberhard
- Marc Tarpenning
- Ian Wright
- Elon Musk
- JB Straubel
The Drama Behind the "Founder" Title
The irony is that while Eberhard and Tarpenning literally filed the paperwork, the Tesla we know today—the global behemoth—is undeniably Musk’s creation. He provided the vast majority of the early funding. He obsessed over the design of the Roadster, insisting on carbon-fiber body panels when others wanted cheaper materials.
Musk didn't just write a check; he took over the steering wheel.
By the time the Roadster actually hit the streets in 2008, Eberhard and Tarpenning were gone. Musk stepped in as CEO during the height of the 2008 financial crisis. The company was days away from bankruptcy. Musk threw in the last of his PayPal money to save it. If he hadn't, Tesla would be a forgotten footnote in a museum of failed startups.
Why the Distinction Actually Matters
You might think this is just a bunch of millionaires arguing over titles. It's not. The debate over who made Tesla motors is a debate about the soul of Silicon Valley. Is a company the "idea" or is it the "execution"?
Eberhard and Tarpenning had the idea. They saw the market shift before anyone else. They proved that lithium-ion was the future. But Musk provided the scale. He moved Tesla from a niche boutique for rich guys in Malibu to a mass-market force that forced every other car company on Earth to change their business model.
Today, Martin Eberhard lives a relatively quiet life, still a shareholder but mostly out of the spotlight. Marc Tarpenning is a venture capitalist. Ian Wright started his own company focused on electric trucks. JB Straubel left in 2019 to start Redwood Materials, a battery recycling giant. And Elon? Well, you know where he is.

How to Think About Tesla’s Origins
If you're researching the history of the EV industry or just curious about how we got here, keep these facts in your back pocket:
- Tesla wasn't a "Musk Original": He was the fourth person to join the cap table.
- The "Secret Master Plan": This famous document, which outlined Tesla’s path from sports cars to affordable sedans, was written by Musk, but the engineering foundation was built by the original team.
- The Lawsuit is Key: Anytime you see a bio of Musk calling him "the founder," remember there are four other guys with a legal right to that title.
If you're looking to understand the modern business landscape, studying the "founder dispute" is a masterclass in how narratives are built. While the original engineers gave Tesla its name and its heart, Musk gave it its teeth.
To dig deeper into this history, you can look up the original Series A funding documents from 2004 or read the 2009 settlement details. Understanding the friction between "visionaries" and "executors" is the best way to predict which startups will actually survive the next decade.
