Over the past two days, Y Combinator held its 38th Demo Day, which continues to be one of the most exciting sets of days in tech.

Over the past two days, Y Combinator held its 38th Demo Day, which continues to be one of the most exciting sets of days in tech. We had the privilege to participate, and we congratulate each of the YC W24 batch founders on their companies’ launches!

As with previous batches, we include in this post our summary takeaways–including both favorite quotes and insightful trends from the founders’ presentations. Y Combinator founders reflect the best of the best at the earliest stages of innovation and startup formation.

Of note, we define enterprise tech broadly, across developer, SMB, large enterprise, and government customer segments. 

I. Favorite Quotes

Over the two days and 243 presentations, we had numerous favorite moments. Some of these are unsolved problem statements about the world. Some of these are contrarian trends. Some are inspiring facts about the founders. Our takeaway quotes from the W24 batch were:

“The current analytics stack just doesn’t cut it for AI.” Dawn

“LLMs will be as ubiquitous as Javascript.” Vectorview

“Ingestion is one of the biggest bottlenecks for deploying enterprise AI applications.” Reducto

Garry Tan projected that 14 of this year’s batch would become unicorns, at least based on prior cohorts’ percentages. For this year, AI tools, data, and developer platforms were the major themes, and healthtech and fintech were the major industry verticals. With that said, we found a remarkably wide range of new applications, enabled and differentiated by LLMs, to reimagine enterprise functional areas and industry verticals. 

To give one sneak peek into next week’s Enterprise Tech 30 report… many of the new ET30 companies this year are in gen AI infrastructure, and many of the returning ET30 companies are in data infrastructure. ET30 companies represent the most promising across early, mid, late, and giga stages. The YC companies represent the company formation stage, and the YC W24 batch tells us that the gen AI applications wave is emerging in enterprise tech, leveraging the gen AI infrastructure and data infrastructure over the past few years.

Congratulations again to the entire YC W24 batch. We’re excited to see what’s next for each of your companies and to collaborate with each of your founding teams across Wing’s activities.
