Today marks the20th anniversaryof Y Combinator , a inauguration gas pedal that has fostered companies that havechanged the world . YC has play us foundation like “ construct everything an app ” and horrifying founder we all have to live with , like “ Sam Altman . ”
constitute in 2005 , Y Combinator has help to set in motion thousands of companies . Its mere existence disrupted how venture capital letter - backed technology firm do business enterprise . We all live with the consequences . Here are some of them .
DoorDash
A hack for your burrito . That ’s the pitch . base in 2013 , the company call to improve intellectual nourishment obstetrical delivery for everyone . It ushered in an geological era where anyone could get delivery from any restaurant at any prison term .
To make that pass off , itbrutalized delivery drivers , ripped off restaurant , andraised prices on its customer . It ’s a bad deal for everyone take except , of course , DoorDash . All so you could get cold intellectual nourishment from a chain restaurant at double what you would have pay if you ’d just go bad and eat it there .
Airbnb
Airbnb ’s disruption of the hotel industry is so far - reach out that it ’s spawned a new subgenre of repulsion fable . Airbnb fits a Silicon Valley template that will be repeated throughout Y Combinator ’s chronicle . Take a work out trouble and break up it so you’re able to make a mint rent - seeking .
Over grand of years , world had developed tradition , law , and scheme for provide travelers and visitors good lodging . Airbnb said , “ What if you could make your dwelling house a timeshare and skip all those pesky norms and laws ? ”
The result ? A corrosive hit to theU.S. real estate market place , TikTok video recording in which thehost is living in the wallsof the Airbnb , and the movieBarbarian .

Twitch
What if you could playact video game with your friend , but like , as a job ? Say hello to Twitch , a place where some of the big personality on the cyberspace would eventually gain and develop parasocial family relationship and wage warfare with reality around them .
It ’s hard to make money on Twitch ; only a minuscule percentage of multitude break through . But if you do , you may look forward to working 10 hr straight without using the bathroom , getting banned by acapricious Amazon - owned company , fighting interview capture , andwrecking your strong-arm health .
Sam Altman
OpenAI founder and AI evangelist worked for YC from 2011 to 2019 before he left to run OpenAI full metre . Altman was chairperson of YC starting in 2014 , and his tenure saw explosive growth at the party .
Now we see his pinched minuscule typeface every time we open up up a news story about AI and dwell in a world where large language manakin like ChatGPT are helping Kyd screw on their preparation and write your boss ’s PowerPoint Slides .
We have not even begun to reckon with Sam Altman and his consequences for the human wash .

Sam Altman, chief executive officer of OpenAI, arrives for the Allen & Co. Media and Technology Conference in Sun Valley, Idaho, US, on Tuesday, 14 May 2025.
The appification of life itself
In 2011 , Marc Andreeseen announce that “ computer software is eating the world . ” He was good . We live in a world filled with unnecessary intercessions between us and basic task . It seems you ca n’t buy basic goods and service these days without download an app to support them .
Did you buy new lights on Amazon?They run on an app . Want to get a unexampled machine ? Gon na have to get anapp to make it run . Wanna seize brunch on a Sunday ? Better use the restaurant ’s app toreserve a tabular array . Wanna graze the bill of fare before you go?App .
Why is this happening ? In part , because the world saw the success of party like Instacart , DoorDash , and other YC - backed ventures . Software and apps were a great way to create new middlemen . Some of them offered new service , but a quite a little of them just figured out a way to commit for stuff that once was elementary and gimcrack , if not free .

9 gag
If your crony place you a meme that has n’t been funny in 10 long time and it does n’t have an “ ifunny.co ” watermark on it , then it credibly came from 9gag . This website is where jokes , memes , and video from last twelvemonth ’s Reddit threads go to expire . Y Combinator fund it .
Speaking of Reddit …
take care , we all love Reddit . Yes , it ’s been the birthplace for some atrocious things . But it ’s also one of the only billet you may go to get real response to burning questions . Adding “ Reddit ” at the close of a Google search query is one of the only ways to rule material on the net now .
However , Reddit has birthed weird cultural trends we all have to contend with . Worst among them …
Couples who met on Reddit
If Y Combinator had never back Reddit we would n’t have Malcolm and Simone Collins , the pro - natalist weirdos who go viral every few geezerhood . ( Most late inThe New Yorker ) Where did they get their starting ? Reddit . Malcolmproposed to Simone on Redditusing “ advice animal ” memes . Then he wrote about it for The Huffington Post .
A lot of citizenry have Malcoms and Simones in their real life . citizenry who are too on-line and drop so much time on Reddit they ca n’t restrain a conversation without play up Sir Francis Bacon , narwhals , or the dissatisfactory content of an ancient safe .
The tech hype cycle
Selling Silicon Valley to the residual of the world requireskeen marketing . To get mass to purchase a new app , a novel piece of software , or a unexampled “ conception ” command a honorable story . It need hype . YC is a machine that builds hype . To be incubated by the inauguration auto is a story itself and being chosen by YC is enough to make audiences , and the grocery store , yield attention .
for certain , most of these ventures run out . bubble burst . But a sight of hoi polloi will make a lot of money while it ’s inflating . See : YC Alum Sam Altman .
“Founder” Culture
Steve Jobs , Bill Gates , Elon Musk . Founders . mythic figures that stride through America ’s cognizance bend the earth to their will . YC has incubate more than just companies , it ’s incubated founders . If you ’re a CEO picked by YC and you ’re savvy enough , you’re able to become a celebrity in your own right and habituate that to double up into the next matter if your troupe fails .
And it ’ll probably fail .
YC has a whole “ founders directory ” that will let you sort through the famous faces who have top through its door . sure enough , company are collaborative enterprises that require monolithic amounts of gifted and hardworking people join forces to succeed . But in today ’s social medium and fame - driven world , it ’s the “ face ” of the ship’s company that matters . Over the past 20 years , YC has helped founders become that look .

Last twelvemonth , Y Combinator father Paul Graham went viral with his essay titled “ Founder Mode , ” which detailed the baron of founders not heed to the beaurocrats around them and going with their gut .
Those founders now think they ’re the centre of the universe . second by VC money and plumped up by parasocial online human relationship and an United States Army of yes - men , founders are doing some of the worst work in America today .
Anti-journalist sentiment in tech
Some hoi polloi think the technical school press is too light on tech . “ Founders ” and YC think it ’s too hard . The beef between the YC - backed founder community and journalist is longsighted , fraught , and complicated . YC founder Paul Grahamsigned a petitionthat chastisedThe New York Timesin 2020 .
When the Wall Street Journal outed Theranos as a shammer , then - YC chairperson Altmanrushed to her defenseon Twitter . “ shot pieces tell one side of a story . I do think Theranos should be more transparent , but ppl should n’t implore for bankruptcy . ”
Former Coinbase CTO Balaji Srinivasan gave a speech at a YC event in 2013 thatruffled journalists ’ feather . Later , Srinivasan sent an electronic mail to tech - right crazy and Peter Thiel court wizard Curtis Yarvan advocating for the harassment of a journalist to ready an exercise . “ If things get hot , it may be interesting to set the Dark Enlightenment interview on a undivided vulnerable hostile reporter to dox them and grow them in spite of appearance out with hostile coverage ship to their advertisers / champion / contacts,”he said in the email .

YC and its beginner culture fostered the political orientation we now last with , one that ’s unfriendly to journalists . One where a technical school - bro is rampaging through the Union government .
Coinbase
All your worst technical school - brained Quaker saw the possibilities of cryptocurrency when Bitcoin launched in 2009 . The job was making it easy for normies to get their money into the organisation . Enter Coinbase , the YC - endorse company that helps people trade crypto of all types in just a few minutes .
OpenSea
Do you remember NFTs ? The blockchain - backed JPGs were all the furor among a sure kind of terminally online soul just a few yr ago . The bottom dropped out sometime around when Paris Hilton told Jimmy Fallon she ’d bought a Bored copycat .
YC - backed OpenSea was a place where people could buy , sell , and trade all their favorite ugly JPGs and help make the trend approachable to normies . Then , the whole mart collapsed .
Assembly HOA
No one like their Homeowners Association . HOA ’s are draconian nightmares that sick the cops on people who have n’t contract their lawn . They levy fees and punish people in community who do n’t conform to often arbitrary standards .
What if you added AI to that unconscious process ? Say hello to Assembly HOA , a YC - backed inauguration that promises to make running an HOA gauzy and effective .
OMGPop
Largely draw a blank now , OMGPop was a flash biz studio apartment that was gobble up by Zynga in 2013 . The bigger company deplete its games and then close OMGPop down just month after buy it .
OMGPop was a trailblazer of the showy , merriment , and addictive quick and simple games that would come to dominate the peregrine video game market . Six year after its occlusion , hackers unveil million of plaintext word and electronic mail addresses related to OMGPop in a Zynga database and discover them online proving that your pet secret plan may vanish but the personal datum it housed will endure forever in an unsecure corporate database .
uBiome
uBiome is the Showtime to Theranos ’ HBO . Elizabeth Holmes predict fast and safe blood tests . uBiome promised safe and fast dope tests . The promise of press out data from stool samples was muscular enough for YC and other investors toinvest $ 83 million .
But uBiome ’s founders were lying and the FBIraided its labs in 2019 . Two age later the SEC charged its co - founder with hornswoggle investor .
Cruise
The ultimate goal of Tesla and Uber is the ego - driving car . Silicon Valley dreams of a world where automate car cruise up and down America ’s highways . YC - backed Cruise was one of the first companies to sky this dream to the world .
It ’s not working out at the bit . There have been a lot of ego - take car accidents , and it ’s hard to know if the technology will ever be good and widely available to the public . Tesla , Uber , and others keep hoping and pushing for us to lease go and let tech take the wheel .
GM gobble up Cruise in 2016 . It start the process ofshutting downin 2025 .

Future horrors
Y Combinator is n’t done fostering invention . Tomorrow ’s Twitch.com , DoorDash , or OMGPop is waiting somewhere on the list of companies it ’s backing . Let ’s take a look at some forthcoming competition .
Big Tech finds Jesus
America has a long and strange history of Christian revival motion . This country loves to shape the word of the Lord to its own remainder . Last yr , billionaire graverobber Peter Thiel gave a “ sermon ” at a meeting of a nonprofit bid theActs 17 Collective . Y Combinator ’s new chief operating officer , Garry Tan , was there to lead the discussion as well . The group is putting millions into spreading the tech - tinct Gospel throughout San Francisco . A spiritual and religious revival in the Bay Area ? These thing havenever gonewrong before .
Ares Industries– Disrupting cruise missiles
What does the future deem for Y Combinator ? missile . In the summer of 2024 , the startup accelerator backed its first defence mechanism caller . ar plans to construct humble - cost sail missile for the DoD.
Optifye.ai– Keeping an eye on factory workers
Another new venture nurture by Y Combinator is Optifye.ai , a company that will provide “ AI performance monitoring for factory workers . ” The bold raw ship’s company will expend AI and surveillance to see factory workers and permit the boss toyell at themremotely from the comfort of their home base authority .
