Warby Parker

Vertically integrated DTC eyewear — Warby Parker designs frames in-house, contracts manufacturing directly (cutting out the brand licensing middlemen), and sells directly to consumers through its website and owned retail stores. The $95 price point (later raised to $95-$195) eliminates the traditional retail markup chain.

Home Try-On program lets customers pick five frames to try for free before buying. Revenue comes from prescription glasses, sunglasses, contact lenses, and eye exams (offered in stores).

The company expanded from pure e-commerce into physical retail with 200+ stores, making it an omnichannel brand rather than purely online.

SpaceX makes money three ways. First, launch services — companies and governments pay SpaceX to put their satellites into orbit.

A Falcon 9 launch costs about $67 million, which undercut the competition by 75% when it debuted. Second, Starlink — SpaceX's own satellite internet constellation, which is now generating over $6 billion in annual revenue from 4+ million subscribers.

Third, government contracts — NASA pays SpaceX to ferry astronauts to the International Space Station and the DoD pays for national security launches.

The secret sauce is reusability. Before SpaceX, every rocket was used once and thrown into the ocean.

SpaceX figured out how to land the first stage booster back on Earth and fly it again. A single Falcon 9 booster has flown over 20 times.

That's like the difference between throwing away an airplane after every flight versus keeping it for decades.

Neil Blumenthal lost a pair of glasses backpacking and couldn't believe replacing them cost $700. He mentioned this at Wharton Business School, where classmates Dave Gilboa, Andrew Hunt, and Jeffrey Raider were having the same reaction.

They dug into the economics and discovered that Luxottica — an Italian conglomerate most people have never heard of — owned Ray-Ban, Oakley, LensCrafters, Sunglass Hut, Pearle Vision, and the licensing rights for Chanel, Prada, and Versace. One company controlled the supply chain from design to retail and priced accordingly.

The four students launched Warby Parker in February 2010 with a simple website selling prescription glasses for $95 — about a quarter of what Luxottica charged. GQ called them "the Netflix of eyewear" before they'd shipped their 100th pair.

They hit their first-year sales target in three weeks and had a 20,000-person waitlist within 48 hours of launch.

In 2001, Elon Musk had just sold PayPal to eBay for $1.5 billion and was sitting on roughly $180 million after taxes. Most people would buy an island.

Musk decided to buy rockets. His original idea was even weirder — he wanted to send a small greenhouse to Mars called "Mars Oasis" to reignite public interest in space exploration.

He flew to Russia three times to buy refurbished ICBMs. The Russians kept raising the price and at one point literally spat on him.

On the flight home from that last failed Russia trip, Musk opened a spreadsheet and started calculating the raw material costs of building a rocket from scratch. He realized the materials were only about 3% of the typical price of a rocket.

The rest was markup, inefficiency, and monopoly pricing by companies like Boeing and Lockheed Martin. He decided to build his own.

SpaceX was founded in June 2002 in a warehouse in El Segundo, California. Musk put in $100 million of his own money.

He hired Tom Mueller, a legendary rocket propulsion engineer who had been building rocket engines in his garage as a hobby. The first rocket, Falcon 1, was supposed to be the cheapest orbital rocket ever built.

It took six years and three spectacular explosions before it finally worked.

The DTC playbook: build a beautiful brand, price dramatically below incumbents, and tell a compelling story about why the old way was a rip-off. The Home Try-On program was brilliant viral marketing — people posted photos of themselves in five different frames on social media asking friends to vote.

"Buy a Pair, Give a Pair" philanthropy (one pair donated for every pair sold) gave the brand a social mission that resonated with millennials. Physical retail expansion gave customers who wanted to try before they buy a real store experience.

Celebrity endorsements and fashion magazine coverage positioned Warby Parker as a lifestyle brand, not just a discount option. Steady geographic expansion of stores into new markets, each store becoming a customer acquisition channel.

SpaceX

SpaceX's growth strategy was simple: be cheaper than everyone, then be better than everyone, then be the only option.

They started by undercutting the launch market. The United Launch Alliance (Boeing + Lockheed Martin joint venture) was charging $300-400 million per launch.

SpaceX offered $67 million. Government agencies and commercial satellite companies started lining up.

Reusability was the real game-changer. Landing a rocket booster looked like science fiction when SpaceX first attempted it in 2013.

They failed over and over — spectacular ocean landings, explosions on drone ships, near-misses. But in December 2015, a Falcon 9 first stage landed back at Cape Canaveral.

It was the first time an orbital-class rocket had ever landed after a mission. Now they do it routinely — it's almost boring.

Starlink created a completely new revenue stream. Instead of just launching other people's satellites, SpaceX launched thousands of its own.

By 2024, Starlink had over 4 million subscribers and was generating billions in revenue. It turned SpaceX from a launch company into a telecom company.

Luxottica (now EssilorLuxottica after merging with the world's largest lens maker) remains a $90 billion behemoth with resources Warby Parker can't match. Post-IPO stock performance has been disappointing — shares fell over 70% from their 2021 highs as the DTC bubble deflated.

Physical retail expansion is capital-intensive and each store needs to reach profitability. Competition from dozens of DTC eyewear brands (Zenni, EyeBuyDirect, Pair Eyewear) that copied the model and often undercut Warby Parker on price.

Prescription eyewear requires optometrist involvement, which adds complexity and regulatory overhead compared to selling non-prescription consumer products. And the fundamental challenge of glasses: people only buy them every 1-3 years, making customer lifetime value dependent on retention across very long purchase cycles.

The early days nearly killed the company. SpaceX's first three Falcon 1 launches all failed.

The first one in 2006 crashed 25 seconds after liftoff due to a corroded fuel line nut. The second in 2007 reached space but the second stage shut down early.

The third in 2008 failed because the first and second stages collided during separation. Musk had enough money for one more attempt.

If flight four failed, SpaceX was dead.

Flight four worked. On September 28, 2008, Falcon 1 became the first privately developed liquid-fuel rocket to reach orbit.

Musk has said he was so stressed during that period he was throwing up regularly.

The financial pressure was existential. Musk was simultaneously funding Tesla, which was also on the brink of bankruptcy in 2008.

He had to split his last $40 million between the two companies. He borrowed money for rent.

But right at the end of 2008, NASA awarded SpaceX a $1.6 billion contract to resupply the International Space Station. That contract saved the company.

Starship development has been its own saga. The rocket has exploded multiple times during testing.

Each failure costs hundreds of millions. But SpaceX treats failures as data — they move faster by blowing things up and iterating than competitors do by being cautious.

Falcon 9 is the workhorse — the most-launched rocket in the world. It carries satellites to orbit and astronauts to the ISS, and the first stage lands itself for reuse.

Falcon Heavy is three Falcon 9 boosters strapped together — the most powerful operational rocket in the world until Starship came along. Dragon is the spacecraft that carries astronauts and cargo to the ISS.

It's the only American vehicle currently flying humans to space. Starlink is the satellite internet service — over 6,000 satellites in orbit delivering broadband to 100+ countries.

Starship is the big one — the tallest and most powerful rocket ever built, designed to carry 100+ people to Mars. It's still in testing but has already completed a full flight.

The company went public on the NYSE in September 2021 via direct listing.
