If you ask a random person on the street who started Tesla, they’ll probably say Elon Musk. They’d be mostly right in the way that matters for the stock price, but historically? They’re kinda wrong.
Tesla wasn't born in a SpaceX hangar or during a late-night coding session at PayPal. It actually started because two guys—Martin Eberhard and Marc Tarpenning—were annoyed that they couldn't find a decent sports car that didn't guzzle gas.
Basically, the "Iron Man" version of the story we see today is the result of a massive corporate evolution, some nasty lawsuits, and a very specific vision that changed hands more than once.
The Guys Who Actually Registered the Paperwork
In July 2003, Tesla Motors was officially incorporated. Musk wasn't there yet. He didn't even know the company existed for several months.
Martin Eberhard and Marc Tarpenning were the real deal engineers who did the legwork. They had just sold an e-reader company called NuvoMedia for nearly $200 million and were looking for their next big thing. Eberhard, who loved fast cars, was tired of choosing between a gas-guzzling Porsche and a dorky, slow electric "golf cart."

They didn't start from scratch. They looked at a kit car called the AC Propulsion tzero, which used heavy lead-acid batteries. Their "lightbulb moment" was realizing that the same lithium-ion batteries used in laptops could be wired together to power a car.
It sounds simple now. Back then? People thought they were insane.
Why the name Tesla?
Eberhard actually came up with the name "Tesla Motors" while at Disneyland with his future wife. It was a tribute to Nikola Tesla, the guy who invented the AC induction motor they planned to use.
Enter Elon Musk: The Series A Gamble
By early 2004, Eberhard and Tarpenning were running out of their own cash. They needed a whale. They eventually pitched to Elon Musk, who had recently walked away from PayPal with a huge pile of money.
Musk didn't just write a check; he led the Series A funding round with $6.5 million. That’s a massive chunk of the initial $7.5 million they raised. Because he put in the lion's share of the money, he became the Chairman of the Board.
The Other Three "Founders"
This is where the history gets a bit messy. While Eberhard and Tarpenning started the company, the legal definition of "who started Tesla motors" was settled in a 2009 lawsuit. Today, five people are legally allowed to call themselves co-founders:
- Martin Eberhard: The original CEO.
- Marc Tarpenning: The original CFO/VP of Engineering.
- Elon Musk: The money man who later became the face of the brand.
- Ian Wright: An early engineer who joined shortly after incorporation.
- JB Straubel: The technical genius who served as CTO for years and was obsessed with battery tech before he even met Musk.
The Coup and the 2009 Legal War
For a few years, things were... okay. But by 2007, the development of the Tesla Roadster was a mess. It was way over budget and behind schedule.
Musk, as Chairman, started getting more hands-on. He wasn't happy with how Eberhard was running things. Eventually, the board (led by Musk) pushed Eberhard out. It wasn't a clean break. It was messy, public, and personal.
Eberhard eventually sued Musk for libel and slander, claiming Musk was trying to "rewrite history" to make it look like he (Elon) started the company alone. They settled out of court. The result of that settlement is why we have the "Five Founders" rule today.

Honestly, it’s a bit like a band where the original drummer gets kicked out right before the first hit record. The new lead singer (Musk) gets all the fame, but the drummer still wrote the first few songs.
What Most People Miss About the "Vision"
There’s a common myth that Musk just "bought" a car company. That’s not quite fair either.
While the original guys had the idea for a sports car, it was Musk who pushed the "Master Plan" of using high-end cars to fund affordable ones. He was the one who insisted on the styling and the brand's luxury identity. Without Musk’s cash and his relentless (and sometimes toxic) drive, Tesla likely would have gone bankrupt in 2008 like every other EV startup of that era.
Actionable Insights: What This Means for You
Understanding who started Tesla motors isn't just trivia; it's a lesson in how modern business works. If you're an entrepreneur or just an observer, here are three things to take away:
- Ownership isn't just about the idea. Ideas are cheap. Execution and funding are what keep the lights on. Eberhard had the idea; Musk had the capital and the scale.
- Founder status is often a legal construct. In the world of high-stakes startups, who gets credit is often decided by lawyers in a conference room, not by who was in the garage first.
- Documentation matters. If you're starting a company with friends, get the "founder" titles and equity split in writing on day one. It saves you a lawsuit five years down the road.
If you want to dig deeper into the actual engineering that separated Tesla from the pack, you should look into the history of the AC Propulsion tzero. It’s the "missing link" that convinced both Eberhard and Musk that electric cars didn't have to suck.
To see how the company evolved from those early days to today's massive scale, you can track the production milestones of the Model S, which was the first vehicle designed entirely in-house after the original founders departed.
