But there’s more to this shift than meets the eye. In a strategic move to enhance the quality of interactions, Y Combinator is cutting cohort sizes in half. This decision isn’t just about numbers; it’s about depth.

With smaller cohorts, investors gain more meaningful time to delve into founders’ business models, understanding their intricacies and evolution. It’s a dynamic that allows for more informed and impactful investment decisions.

A Front-Row Seat to Innovation

For those of us keenly watching the frontiers of artificial intelligence (AI) and machine learning (ML), this change is particularly thrilling.

Each batch presents a fresh opportunity to back startups leveraging the latest AI advancements to create tools that revolutionize enterprise applications. Every iteration of Y Combinator’s cohorts reveals a new wave of talent—founders with profound domain expertise who are redefining what’s possible with software. These startups aren’t just building; they’re enabling the future, one innovation at a time.

The YC portfolio spans a broad spectrum, from AI-driven software to disruptive healthcare technologies.

As these companies make their debut through Y Combinator, we attempt to reach out, make friends and profile hem before their big raise and demo day.

The Rise of Vertical Software and AI

The S24 batch has spotlighted a compelling trend: the rise of vertical software solutions, powered by AI.

An astonishing 75% of founders in this batch are building AI-related products, underscoring AI’s transformative role across industries.

These startups are no longer experimenting; they’re embedding AI at the core of their offerings, using machine learning to automate complex workflows once dominated by skilled professionals.

From healthcare to fintech, productivity to industrial automation, the surge in industry-specific software marks a departure from the one-size-fits-all approach of the past. Startups now deliver tailored solutions that address niche problems with surgical precision, often leveraging AI to understand and process unstructured data in ways that were previously unimaginable.
