Airbnb

Airbnb is a two-sided marketplace. Hosts list their homes, apartments, treehouses, or whatever else they've got.

Guests book and pay through the platform. Airbnb takes a cut from both sides — roughly 3% from hosts and up to 14% from guests as a service fee.

That's it. They don't own a single property.

They just built the world's largest hotel chain without owning a single bed.

Magic AI

Magic is building an AI that works like a software engineer, not a chatbot. The goal is a model you can hand a whole code base and a task, and it writes, reviews, and debugs like a teammate.

Their edge is memory. In 2024 they showed off LTM-2-mini, a model with a 100 million token context window.

To put that in perspective, that is about 10 million lines of code the model can look at in one shot, by far the biggest of any model at the time. The plan is to sell this as an AI coworker to companies that write a lot of software.

As of the 2024 rounds, the product was still not for sale.

In 2007, Brian Chesky and Joe Gebbia were two Rhode Island School of Design grads living in San Francisco and struggling to make rent. A big design conference was coming to town and every hotel was booked solid.

They bought three air mattresses, put up a simple website called AirBed & Breakfast, and charged $80 a night including a homemade breakfast. Three strangers actually showed up.

That was it — the entire origin story of a $75 billion company is three air mattresses and desperation.

They recruited Nathan Blecharczyk, a Harvard-trained engineer Joe knew, to build the real website. But nobody wanted to fund them.

They applied to 15 investors and got rejected by every single one. To keep the company alive during the 2008 election, they designed limited-edition cereal boxes — Obama O's and Cap'n McCain's — and hand-assembled 500 of each.

They sold the Obama O's for $40 a box and made $30,000. That cereal money literally kept Airbnb from dying.

Paul Graham at Y Combinator finally let them into the Winter 2009 batch — reportedly because the cereal stunt proved they were "cockroaches" who would never die. YC invested $20,000.

Within a few months, Sequoia Capital led a $600,000 seed round. The rest is history.

Magic AI

Eric Steinberger and Sebastian De Ro started Magic in 2022. Steinberger is an AI researcher who became convinced that the missing piece for a true AI software engineer was memory.

Chatbots forget what you told them a few thousand words ago. He wanted a model that could read your entire code base and remember all of it.

They raised a small seed in 2022, then a $23 million Series A in early 2023 led by Alphabet's growth fund CapitalG. From day one the pitch was not a chatbot.

It was an AI colleague that could handle real engineering work.

The early growth was pure hustle. Chesky and Gebbia flew to New York — their biggest market — and went door to door visiting hosts.

They noticed the listings with bad photos got no bookings. So they offered free professional photography to every host.

Bookings exploded. That single move — better photos — was probably worth more than any ad campaign they ever ran.

They also pulled one of the most legendary growth hacks in startup history. They reverse-engineered Craigslist's posting system so that Airbnb hosts could cross-post their listings to Craigslist with one click.

Craigslist had millions of people looking for rentals. Airbnb had none.

The hack funneled Craigslist's traffic straight into Airbnb. It was borderline shady and absolutely brilliant.

Word of mouth did the rest. Every guest who had a great stay told their friends.

Every host who made easy money told their neighbors. The product sold itself because both sides benefited immediately.

By 2015, Airbnb had more listings than the top five hotel chains combined.

Magic AI

Magic's strategy is research first, product later, which is both unusual and expensive. Instead of shipping an app and iterating in public, they raised huge sums to chase a technical breakthrough in model memory.

The headline move was the 100 million token context claim, which got the whole AI world talking. They also cut a deal with Google Cloud in 2024 to build two supercomputers, called Magic-G4 and Magic-G5, using NVIDIA chips, to train bigger models.

Star backers like Eric Schmidt served as validation. The bet is that if the tech is far enough ahead, the product and the customers follow.

Airbnb

Regulation. Full stop.

Cities around the world have gone to war with Airbnb. New York, Barcelona, Amsterdam, Paris, Berlin — all have passed laws restricting or outright banning short-term rentals.

The hotel lobby has spent hundreds of millions fighting Airbnb at every level of government. In New York City, a 2023 law essentially banned most Airbnb listings overnight.

Then COVID hit. In March 2020, Airbnb's business dropped 80% in eight weeks.

Chesky had to lay off 1,900 employees — 25% of the company — in a single memo that became famous for how honest it was. He gave everyone 14 weeks of severance and a year of health insurance.

The company burned through its IPO plans and took on $2 billion in emergency debt at brutal interest rates.

But here's the thing — COVID also saved them. People stopped wanting hotel lobbies and started wanting isolated cabins and rural homes.

Airbnb's bookings came roaring back by summer 2020, and the rural/unique stays trend became permanent. They IPO'd in December 2020 at a valuation that stunned everyone.

Magic AI

Magic has raised close to half a billion dollars and, years in, still has no product the public can buy. That is the whole problem in one sentence.

A giant context window is a great demo, but rivals like Cursor, GitHub Copilot, and Cognition's Devin already have real users and revenue. Magic has to prove that more memory actually makes a smarter engineer, not just a bigger number on a slide.

And it has to do that while burning enormous sums on compute against competitors who are already shipping. The clock and the cash both keep running.

Airbnb

Airbnb Stays is the core product — book someone's home instead of a hotel. Airbnb Experiences lets you book local activities run by hosts, like cooking classes in Rome or surf lessons in Bali.

Airbnb Luxe is the ultra-premium tier — think private islands, castles, and villas with dedicated concierge service. Airbnb Plus, an inspected-homes tier, was wound down in 2023 after proving too costly to verify at scale.

Categories (launched 2022) lets you browse by vibe — treehouses, lakefront, tiny homes, mansions — instead of just searching by location.

Magic AI

The centerpiece is Magic's LTM, or Long-Term Memory, model family. In 2024 they unveiled LTM-2-mini, a model with a 100 million token context window, pitched as the key to an AI that can understand an entire code base at once.

The broader product is an AI software engineer, or coworker, that can write and change code across a whole project. The company also announced Magic-G4 and Magic-G5, two supercomputers built with Google Cloud and NVIDIA to train these models.

Much of it is still research rather than a shipping product.

Magic AI

Magic's backers are a murderers' row of AI insiders. It started with a $5 million seed round in 2022 and a $23 million Series A in early 2023 led by Alphabet's CapitalG.

Then in February 2024 came a $117 million round led by Nat Friedman and Daniel Gross, two of the most connected investors in AI. The blowout was August 2024.

Magic raised $320 million with checks from former Google CEO Eric Schmidt, CapitalG again, Atlassian, Jane Street, Sequoia, and Elad Gil. That pushed total funding to around $465 million, all for a company still building toward its first sellable product.
