How To Be Contrarian — And Right
Y Combinator· 2025-10-17 14:00
Startup Strategy & Competition in AI - The AI industry is seeing increased competition, making it crucial for startups to differentiate themselves through unique insights and contrarian bets [1] - New technology platforms typically offer a two-year window of opportunity before the market becomes saturated with obvious ideas [2] - Startups should focus on identifying and addressing genuine human needs rather than pursuing trendy or derivative ideas [1] - Founders should re-examine conventional wisdom and challenge established playbooks to discover innovative approaches [25] Contrarian Thinking & Identifying Opportunities - Discovering a "secret," or a belief that is not yet widely accepted, is key to standing out from the competition [1] - Great startup ideas often exist in a legal "gray area" where laws may not be clearly defined or up-to-date with technological advancements [4][16] - Founders should focus on first principles thinking to identify user needs and societal benefits, even if it means challenging existing regulations [13][15] Case Studies & Examples - DoorDash succeeded by focusing solely on delivery, a contrarian approach to the "full-stack startup" trend of the time [25] - Coinbase initially faced criticism for working with banks and regulators, a contrarian approach to the cypherpunk ethos of early Bitcoin adopters [9] - Flock Safety, now valued at $75 billion, initially faced skepticism due to its hardware focus and small target market [53] Emerging Trends & Potential Shifts - The "forward-deployed engineer" model, while currently popular, may be ripe for disruption by AI-powered solutions [35] - Code generation is reducing switching costs for enterprise software, enabling startups to compete with established players like NetSuite [30] - AI-powered solutions can transform customer data and business logic in minutes, offering a significant advantage over human-driven approaches [36]
What Everyone Is Getting Wrong About AI And Jobs
Y Combinator· 2025-10-14 14:00
Is AI going to make human labor obsolete. Right now, the loudest voices on both sides of the AI jobs debate are in hysterics. On the one hand, you've got doomers who are convinced we're a couple of years away from near universal unemployment.Over a 5-year period, it could wipe out half of white collar entrylevel jobs. Unemployment could spike to 10 to 20% in the next 5 years. So, we're looking at a world where we have levels of unemployment we never seen before.On the other hand, you've got people who think ...
The World's First Commercial Mobile Carbon Capture Device

Engineering & AI Pitfalls - Focusing on a single measure of success in engineering can lead to neglecting other important aspects [1] - Achieving targets without considering the broader context results in missing the points [1][2] - AI's success in chess, exemplified by Deep Blue beating Kasparov, did not advance the understanding of human intelligence [2]
Every AI Founder Should Be Asking These Questions
Y Combinator· 2025-10-07 14:00
Welcome to this this talk. I'm extremely confused. Uh I think maybe more confused than I've ever been in my entire life. Probably definitely more confused than I've ever been in my entire life. Uh and I want to talk about that because I think I don't know when you're confused. That's the start of something interesting. If you're trained as a scientist, that's like the thing you want to pay most attention to is that moment where you're confused like, "Oh, this is interesting. I don't know what's about to hap ...

Don’t Be Afraid to Talk About Price
Y Combinator· 2025-09-19 01:51
Founders are often very afraid to have a willingness to pay conversation. They feel like if they bring a dollar amount up, it might scare the customer off. But honestly, that's almost always not true.It's so so important to have the conversation with a customer. If I can solve this problem for you and deliver these metrics we've talked about, how much would that be worth to you. You really need to disqualify customers who just aren't ready, able, or willing to buy your. ...
"Startups only exist to find product-market fit."
Y Combinator· 2025-09-14 22:05
Startup Focus - Startups should prioritize achieving product-market fit above all else [1] - Every dollar and effort in a funded startup should be directed towards finding product-market fit [2] - The core team, consisting of founders, their computers, and potentially one engineer, is often sufficient in the early stages [2] Avoiding Big Company Traps - Startups should not emulate big companies by replicating their functions prematurely [1] - Investing in unnecessary resources like offices or excessive departments can be a distraction and detrimental to progress [3] - Focusing on appearing "grown up" like bigger companies can be counterproductive if it diverts attention from core objectives [3] Resource Allocation - Unlike big companies, startups should avoid spending on functions that are not essential for achieving product-market fit [1] - Prematurely hiring for roles that are not yet needed can create management overhead and hinder focus [3]
Agency and Independence
Y Combinator· 2025-09-10 17:40
It's pretty clear now in the AI world that like the AI is very good at following instructions and it's probably going to be hard for humans to compete with the AI on just like following instructions reliably. In which case people here need to think about what are they going to get out of their college experience. That goes beyond just kind of showing up passing the test following the instructions really really well.like it's going to require how do you know to do things yourself and how do you have like age ...
