🫑 3-Line Summary
•
Y Combinator (YC) is investing heavily in AI-based labor support and replacement services, noting that humans pay the most money to hire the labor of others.
•
The AI portfolios recently produced by YC mainly consist of automating CS and administrative tasks in specific specialized fields (vertical markets), such as heavy equipment rental, dentistry, and financial research.
•
AI solutions designed to completely replace humans, such as medical consultations, must carefully review country-specific legal regulations and risks, even if technical implementation is feasible.
🥦 Insight
•
Targeting the areas where people are already willing to open their wallets
Service planners and entrepreneurs often feel pressured to create entirely new markets. However, as YC's recent move demonstrates, the surest shortcut is to use AI to streamline areas where companies are already spending significant costs hiring employees or freelancers.

Korean-style Opportunities Discovered in the Vertical CS Field
Rather than simply importing a heavy equipment CS AI model targeting the US market, it appears that introducing a customized CS AI for specialized markets in Korea, such as dermatology or plastic surgery where periodic reservations and customer management are key, would be a highly viable business opportunity domestically.

Balancing Replacement and Assistance
If you start with the grandiose goal of completely replacing human experts while intoxicated by a technological utopia, you are likely to run into regulatory hurdles. In the beginning, it is much more advantageous for circumventing regulations and entering the market to approach it as a reliable assistant that boosts productivity tenfold by helping with simple, repetitive tasks performed by experts.
🥄 A spoonful of execution
•
Among the business or tasks you are currently preparing, what are the repetitive tasks that incur fixed monthly labor costs or take the most time? If you were to entrust that process to an AI agent, please list just one task that you could automate first.

Sam Altman, the father of OpenAI, is actually one of the founders of Y Combinator (hereinafter YC).
Perhaps for this reason, YC has recently been investing heavily in AI, and for the past few years, it has been continuously focusing on AI startups, training and producing graduates through batch programs.
So, what do the AI startups that YC is heavily betting on have in common?
In the video "From Idea to $650M Exit: Lessons in Building AI Startups" uploaded to YC's official channel, Jake Heller, who sold an AI company called CoCounsel for $650M (which is nearly 1 trillion at current exchange rates, meaning it is a unicorn), directly explains YC's perspective on the great potential it sees in AI.
