Founded in 2013, the company promised to improve food delivery for everyone.

It ushered in an era where anyone could get delivery from any restaurant at any time.

To make that happen, itbrutalized delivery drivers,ripped off restaurants, andraised prices on its customers.

Its a bad deal for everyone involved except, of course, DoorDash.

Airbnb fits a Silicon Valley template that will be repeated throughout Y Combinators history.

Take a solved problem and disrupt it so it’s possible for you to make a mint rent-seeking.

A corrosive hit to theU.S.

Its hard to make money on Twitch; only a small percentage of people break through.

We have not even begun to reckon with Sam Altman and his consequences for the human race.

The appification of life itself

In 2011, Marc Andreeseen declared that software is eating the world.

We live in a world filled with unnecessary intercessions between us and basic tasks.

This website is where jokes, memes, and videos from last years Reddit threads go to die.

Y Combinator funded it.

Speaking of Reddit …

Reddit

Look, we all love Reddit.

Dozens of beachfront homes in Malibu, CA were destroyed overnight in the Palisades Fire on Wednesday, January 8, 2025.

Yes, its been the birthplace for some horrible things.

However, Reddit has birthed weird cultural trends we all have to contend with.

(Most recently inThe New Yorker) Where did they get their start?

A shot of an IRS building looking up at it from a very low angle.

Malcolmproposed to Simone on Redditusing advice animal memes.

Then he wrote about it for The Huffington Post.

A lot of people have Malcoms and Simones in their real life.

The tech hype cycle

Selling Silicon Valley to the rest of the world requireskeen marketing.

YC is a machine that builds hype.

Sure, most of these ventures fail.

Predator Badlands

But a lot of people will make a lot of money while its inflating.

See: YC Alum Sam Altman.

Founder Culture

Steve Jobs, Bill Gates, Elon Musk.

Jblflip6

Mythological figures that stride through Americas consciousness bending the world to their will.

YC has incubated more than just companies, its incubated founders.

And itll probably fail.

Eufysolocam

Sure, companies are collaborative enterprises that require massive amounts of talented and hardworking people cooperating to succeed.

But in todays social media and celebrity-driven world, its the face of the company that matters.

Over the past 20 years, YC has helped founders become that face.

Alicia Witt in Urban Legend

Those founders now think theyre the center of the universe.

Anti-journalist sentiment in tech

Some people think the tech press is too easy on tech.

Founders and YC think its too hard.

The beef between the YC-backed founder community and journalists is long, fraught, and complicated.

YC founder Paul Grahamsigned a petitionthat chastisedThe New York Timesin 2020.

When the Wall Street Journal outed Theranos as a fraud, then-YC president Altmanrushed to her defenseon Twitter.

U.S. President Donald Trump speaks to the media during a guided tour of the John F. Kennedy Center for the Performing Arts before leading a board meeting on March 17, 2025 in Washington, DC.

Slam pieces tell one side of a story.

I do think Theranos should be more transparent, but ppl shouldnt pray for failure.

Former Coinbase CTO Balaji Srinivasan gave a speech at a YC event in 2013 thatruffled journalists feathers.

Metaquest3s

YC and its founder culture fostered the ideology we now live with, one thats hostile to journalists.

One where a tech-bro is rampaging through the federal government.

Coinbase

All your worst tech-brained friends saw the possibilities of cryptocurrency when Bitcoin launched in 2009.

Anker Desktop Charger

The problem was making it easy for normies to get their money into the system.

Enter Coinbase, the YC-backed company that helps people trade crypto of all types in just a few minutes.

OpenSea

Do you remember NFTs?

Predator Badlands

The bottom dropped out sometime around when Paris Hilton told Jimmy Fallon shed bought a Bored Ape.

Then, the whole market collapsed.

Assembly HOA

No one likes their Homeowners Association.

Jblflip6

HOAs are draconian nightmares that sick the cops on people who havent cut their lawns.

They levy fees and punish people in communities who dont conform to often arbitrary standards.

What if you added AI to that process?

Eufysolocam

Say hello to Assembly HOA, a YC-backed startup that promises to make running an HOA transparent and efficient.

The bigger company ate its games and then shut OMGPop down just months after buying it.

uBiome

uBiome is the Showtime to Theranos HBO.

Elizabeth Holmes promised fast and safe blood tests.

uBiome promised safe and fast poop tests.

But uBiomes founders were lying and the FBIraided its labs in 2019.

An image of a hand holding a black vape with a vibrant blue chamber where you can faintly see a laser.

Two years later the SEC charged its co-founders with defrauding investors.

Cruise

The ultimate goal of Tesla and Uber is the self-driving car.

Silicon Valley dreams of a world where automated cars cruise up and down Americas highways.

Framework 13 Laptop 1 Hero

YC-backed Cruise was one of the first companies to pitch this dream to the world.

Its not working out at the moment.

GM gobbled up Cruise in 2016.

Samsung Odyssey 3d 6

It began the process ofshutting downin 2025.

Future horrors

Y Combinator isnt done fostering innovation.

Tomorrows Twitch.com, DoorDash, or OMGPop is waiting somewhere on the list of companies its backing.

Lets take a look at some upcoming contenders.

Big Tech finds Jesus

America has a long and strange history of Christian revival movements.

This country loves to shape the word of the Lord to its own ends.

Y Combinators newest CEO, Garry Tan, was there to lead the discussion as well.

The group is putting millions into spreading the tech-tinged Gospel throughout San Francisco.

A spiritual and religious revival in the Bay Area?

These things havenever gonewrong before.

Ares Industries Disrupting cruise missiles

What does the future hold for Y Combinator?

In the summer of 2024, the startup accelerator backed its first defense company.

Ares plans to build low-cost cruise missiles for the DoD.
