Discord

Discord makes money primarily through Nitro — a $9.99/month subscription that gives users bigger file uploads, HD video streaming, custom emoji, animated avatars, and profile customization. There's also Nitro Basic at $2.99/month with fewer perks.

Server owners can pay for Server Boosts that unlock premium features for their community. Discord also added a cut of server subscriptions — creators can charge monthly membership fees and Discord takes 10%.

The key insight is that Discord's core product is completely free. Voice chat, text chat, screen sharing, communities with thousands of members — all free.

Nitro is cosmetic and convenience upgrades. Most users never pay and Discord is fine with that.

The free users create the network effects that make the platform valuable.

SpaceX

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.

Jason Citron had already built and sold a gaming company — OpenFeint, a social gaming platform for mobile, which GREE bought for $104 million in 2011. After that, he started Hammer & Chisel, a game studio that was supposed to make mobile games.

The game they built, called Fates Forever, was a mobile MOBA that got great reviews but almost nobody played.

What Citron noticed was that gamers were using terrible tools to communicate. TeamSpeak was clunky.

Skype was laggy. Nothing worked well for groups of people who needed to talk while gaming.

The internal voice and text chat tool that Hammer & Chisel had built for their own team worked better than anything on the market.

Citron and co-founder Stan Vishnevskiy pivoted the entire company. They stripped out the gaming stuff and launched Discord in May 2015 as a free voice, video, and text chat platform for gamers.

It spread through Reddit first — a post on the r/gaming subreddit went viral and crashed their servers on day one. Within a year they had 25 million registered users.

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.

Discord

Discord grew through communities, not ads. The first users were gamers on Reddit and Twitch who were sick of TeamSpeak and Skype.

Streamers would set up Discord servers for their fans, and every viewer who joined brought their friends. The growth was entirely organic for years.

The bot ecosystem was the secret weapon. Discord made it trivially easy to build bots — automated programs that add functionality to servers.

Music bots, moderation bots, gaming bots, utility bots. Developers built tens of thousands of bots, each one making Discord servers more useful and sticky.

A server with good bots became a mini-app platform.

COVID and the "beyond gaming" shift were massive. When lockdowns hit, study groups, book clubs, art communities, crypto communities, and just friend groups all started using Discord.

By 2020, non-gaming usage overtook gaming usage. Discord quietly dropped the "for gamers" tagline and rebranded as a platform for communities of all kinds.

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.

Monetization has been the eternal question. Discord has 200 million monthly active users but has never turned a profit.

Nitro subscriptions are growing but most users are happy on the free tier. Unlike Facebook or Twitter, Discord doesn't run ads — they've explicitly said ads in DMs or chat would destroy the product.

Finding ways to monetize without betraying user trust is the core challenge.

The Microsoft acquisition saga. In early 2021, Microsoft reportedly offered $12 billion to buy Discord.

Citron and the board walked away. The thinking was that Discord could grow into something worth much more independently.

Whether that was the right call depends on whether Discord can eventually figure out profitability — Microsoft would have solved that problem instantly with its distribution.

Content moderation at scale is brutal. With millions of servers and hundreds of millions of users, Discord has struggled with harmful content — extremist groups, CSAM, doxxing, and harassment.

They've invested heavily in trust and safety teams and automated detection, but the decentralized nature of servers makes moderation much harder than a centralized feed like Twitter or Facebook.

SpaceX

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.

Discord

Discord's core is servers — community spaces organized into text and voice channels. Think of a server like a clubhouse with different rooms for different topics.

Voice Channels let you drop in and out of audio conversations like a walkie-talkie. Stage Channels are for live audio events with audiences.

Forum Channels organize discussions by topic. Discord also has direct messaging, group chats, video calls, screen sharing, and a growing app/bot ecosystem.

Activities let users play games and watch videos together inside Discord calls.

SpaceX

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.
