I've read maybe ~10,000 YC applications. 8000 for YC admissions/PG quite a few years ago and anther 2000 informally as an alum.
There's a new and growing mistake and I want to share why it's more important than you think.
By the way - I try not to ever say YC admissions works this way or that way. That's YC's job and they're always changing things and making up their own minds.
But I will share my impression and you can see what you think - YC partners, please chime in as well if you like.
The YC application is fundamentally an evaluation of a founder's potential. And much less an evaluation of a specific business. (Airbedbreakfast transitioning into Airbnb because Brian, Nate, Joe never give up and never stop listening to their customers)
So, in your writing of the application, YOU need to shine through.
This batch, I read ~200 applications.
I'm guessing over half were significantly written, edited, or polished with AI.
That half was easily in the bottom half of my informal rankings, almost every time.
To be clear, most were NOT AI slop. I often couldn't tell at first they had used AI. Founders were pouring their heart and soul into their app - so I what I received was high quality.
But I think the AI really hurt them. Here's why:
Once polished by AI, I as reader lost insight into the personality of the writer.
I love the YC application because the questions are the same questions I would ask in office hours or casually to a friend that wanted help with their startup. It pushes the founder out of their pitchdeck/VC talk style into simple worded questions that can be answered simply as well. And great founders shine through when they just write like they talk. The LLM writing made answers feel more like a corporate cover letter, with the personality drained out.
The AI-assisted drafts also gave me a sense of mid work. The writing itself seemed like zero standard deviations from the mean. The LLMs had lopped off the outlier portions of sentences, paragraphs, and thoughts. Given the YC App is an outlier detector, a writing tool that lops off outlier writing is the opposite of what you want.
And the AI writing was needlessly verbose. Which hurts when a reliable predictor of great founders is that they're deep thinkers and deep thinking shines through in the density of their writing.
So...
I did an experiment. I asked a bunch of these seemingly AI-assisted app writers to talk with me live. I just asked them the same YC app questions and recorded their answers.
I then gave them back the transcripts. Unedited and unpolished.
And...
OMG! A good number turned from easy no to actual good applications.
Magic! Remove AI >> Improve application.
This happened BOTH with native English speakers and founders abroad.
So this is my recommendation to all of you.
Don't let AI touch your application, even for a second.
And maybe try the dictation approach with a friend.
My apologies to the YC admissions team if you already knew AI-written applications were crap and you were using this insight to help you easily move applications to the No pile.
YC's Winter Batch Application deadline is Nov 2nd.

We built PlanAssist to help UK Government planning officers speed up building and renovations across the country.
Built with Gemini, it has shown it can cut the time planning officers spend assessing householder applications by up to 58%. It is now being made available to 12 more councils to help them to make faster decisions. 🏡 → goo.gle/4iQXYkl
So true
We’ve tried both and both b2b sales and self serve are hard in different ways
Self serve is easier to be tricked into thinking it’s easy by seeing viral stories on the internet
We’re no longer exploring self serve for now as we don’t have a clear upgrade path
people assume you need a sales team to grow a b2b company
but we added most of our recent revenue self-serve
just people finding the product, understanding it, and paying
that only works if you do the unglamorous work upfront
the pricing has to be legible
the product has to explain itself without a human on a call
the value has to be obvious within the first few minutes or the person leaves
not always easy if you have a sophisticated saas product tho
but either way self-serve isnt the easy path
because instead of a salesperson absorbing all the confusion in a call
the product has to absorb it in the design
but when it works, it pays off in a way sales never can
a good salesperson closes one deal at a time
a product that sells itself closes deals while you sleep
which is why the goal was never to avoid sales because sales is bad
it was to build something clear enough that most people never needed the call in the first place

I used this treatment last year and my tinnitus is basically gone.
A groundbreaking treatment pairing auditory tones with mild electrical shocks rewires the brain to quiet chronic tinnitus.
Chronic tinnitus, the agonizing perception of ringing in the ears without an external sound source, affects millions worldwide and has long eluded effective medical intervention.
However, innovative research in neuroscience shows that bimodal neuromodulation—a technique combining audio tones with gentle electrical stimulation delivered directly to the tongue—can effectively quiet these phantom sounds.
By stimulating touch receptors on the tongue while simultaneously playing targeted acoustic signals through headphones, the treatment leverages the brain's natural neuroplasticity. This dual-sensory approach encourages the central nervous system to reframe its sensory processing, essentially retraining the brain to ignore hyperactive auditory signals.
In a landmark clinical study involving over 300 adults suffering from chronic subjective tinnitus, more than 86% of compliant participants experienced a significant reduction in symptom severity following 12 weeks of daily treatment.
Remarkably, these therapeutic benefits persisted for up to 12 months post-treatment, representing a major leap forward in long-term tinnitus care. Described by patients as feeling like a mild fizzing sensation on the tongue, this non-invasive therapy offers a promising and safe alternative to traditional management strategies, bringing renewed hope to millions seeking lasting relief.

Great piece here. The race to try to compete with and replicate China's industrial prowess misses so many of the crucial elements of how Chinese industry boomed.
China has become the most important manufacturing economy in the world because it is a continent-sized Silicon Valley.
worksinprogress.co/issue/chi…
Every Chinese city govt acts as a VC firm trying to create clusters in its region, because it has both the means and incentive to do so.
Local govts generate their revenues, nearly all of which they keep, from selling leases on land and from stakes they have taken in local companies, which together allow them to capture economic spillovers.
Chinese officials have their entire careers graded and determined by how much growth they have been able to create in the areas they run. Career progression is determined according to a great tournament that pits official against official and gives promotions to whoever has grown their region the most. If they don’t reach a certain stage by a certain age they are blocked from promotion forever.
This is why so many economic clusters have centred on Chinese cities, for high- and low-tech products alike. Shaodong makes 70% of the entire world's cigarette lighters; Danyang makes half of the world's spectacle lenses; Zheng'an makes 1/7 of the world's guitars; Datang a third of its socks.
Whereas many of the West’s most important city governments capture only a small amount of the spillovers from successful clusters, and thus have very little reason to foster them, in China, they get a huge amount of the upside and can re-invest it in further growth. This also gives them a great incentive to solve problems for companies, like when Shanghai's govt got Tesla's factory there built even faster than Elon himself had expected (and twice as fast as his Fremont, CA factory).
But this is not some exotic 'oriental' innovation – this is how America used to do things when it grew fastest, in the 1950s, 1960s, and early 1970s. Catching up with China on advanced manufacturing does not require a wise and strategic approach, let alone authoritarianism or the end of democracy. It may just mean fixing city government.
This is why I care so much about local in Britain and America: if we give our own local governments the same incentives and means to grow, the crazily dysfunctional entities we have become used to may be transformed into corporation-like bodies that are ruthlessly focused on making their cities rich, safe and prosperous.

Assorted things I've been mulling over regarding agents in the economy:
• Companies are in some sense the original superintelligence. It's often the case that they can use their amortized cognitive surplus to advance their interests against those of certain consumers: relative to the optimization capacity of companies, consumers can be inattentive, underinformed, irrational, etc. (Think, say, of some of the classic insurance upsells at the end of a booking process, which is typically priced substantially above what a regular policy would cost.) Herbert Simon introduced the idea of bounded rationality, and firms often end up benefiting from it. Thanks to personal agents, we will probably get somewhat more rational in how we engage with companies.
• How exactly will outcomes change? Well, certain kinds of price discrimination will work less well (how do coupons work if every agent hunts fastidiously for them?), and certain kinds of customer cross-subsidy will change (today, people who forget to cancel subscriptions subsidize those who don't). Taken across the economy as a whole, I'm not sure what the incidence of all of this will be.
• In corporate strategy, people have long debated the relative importance of distribution and product quality. Perhaps you've made something better, but does anyone know about it? Won't people just continue to buy the ACME Corp Mousetraps? Personal agents will, I think, act as a kind of structural subsidy for product quality. How would markets look different if individuals always spent at least 10 hours researching their purchases? On the margin, focusing on making a product better is, I think, going to become a more effective strategy for companies. This is good!
• It true, a corollary is that information about product quality will become more important and impactful. Today, most people have very limited ability to aggregate and integrate such data, but agents will have insatiable thirst for such signals. (It's often said that data is becoming more valuable because it helps in the training of models. That's obviously true, but I think there's a secondary way in which it's more valuable simply as a complement to cheaper intelligence.)
• A big question is whether agents will increase superstar effects (rational agents all settle on the same product) or increase dispersion (because everyone has slightly different tastes and preferences, which agents are good at eliciting, finally overcoming the artificial clustering we've been subjected to).
• Many internet companies have monetized demand routing, which is in turn often predicated on short attention spans. "I'll click on the first thing I see." This has led to some amount of inefficiency, as companies try to propitiate capricious ranking algorithms and incur various placement fees. It's not all deadweight loss (willingness to pay is itself a kind of signal, which is valuable to buyers), but it's not great. How will the nature and value of this routing change in a world of personal agents? I don't know the answer, but I think that the effects might be pretty big.
• Much of what I'm writing hinges on the assumption that personal agents will be on the consumer's side. I suspect that that will be the winning strategy, but whether it's true, and what it means to be true, involves a lot of other questions.
Taken as a whole, the market is a massively parallelized, decentralized, and highly imperfect value attribution machine, and, taking stock of all of the effects, it seems to me that the quality point may well be the biggest: that agents will change the nature of the backpropagation such that the rewards for better products increase. Maybe this is too optimistic, but I suspect (and hope) that companies that make things that they're proud of will feel that the universe is a little more partisan in their favor.

Life update: dropping the "Visiting" — I'm joining @ycombinator as a General Partner 🤩
YC was my first choice as a founder in 2019. Seven years later, I'm choosing it again.
This past year, I got to come full circle: working with founders through the W26 and S26 batches, helping them turn early ideas into products people love.
I'm incredibly excited to keep finding founders and helping them build the iconic companies of this generation 🔥

The UK’s most powerful government-built AI supercomputer, Isambard-AI, cost £225m
The Botley Road bridge cost roughly the same
Apparently our frontier AI capacity and one bridge are comparable national investments

i’ve watched a lot of friends make unnecessarily costly decisions under the assumption that every element of one’s life must be a political expression — including:
staying in exploitative nonprofit jobs, forgoing kids bc of climate change guilt, hooking themselves up to an IV drip of political news when it makes them miserable, cutting off family with even slight political disagreements.
and i think very little of it redounds to any public benefit. it often impoverishes their life and by extension others’.
the most effective and resilient public interest advocates i know cut themselves and others a lot of slack, because life is hard enough.
A gift link, because this piece is indeed bracing and worth reading in its entirety: nytimes.com/2026/09/20/magaz…

before you freak out:
this result barely has anything to do with AI. it just shows how willing Anthropic is to spend on bruteforce:
1. this does not break encryption. numbers used in RSA are much larger
2. this is still mostly a brute force effort, 2048 GPUs ran for 10 days
3. Claude implemented the algorithm to run on Anthropic's GPUs, but it didn't invent or improve it
4. RSA-896, despite its name, only has 270 decimal digits; it was expected to be bruteforced eventually, it was just a question of who'd commit enough capital
