Last week, the YC Winter 2023 batch presented their new businesses to an invitation-only group of investors, press, and others in the startup community. The two days included 265 startups, who were selected by YC from a pool of 20,000 applicants.
In this post, we look to highlight the major themes and trends in the batch - so as to ascertain what might be next for enterprise tech. YC has an outstanding track record of success, with 300+ companies in its 18-year history valued at $150M+ and 90 companies valued at $1B+.
Before we begin, we would like to congratulate all YC W23 founders! It was a privilege to participate in Demo Day and to listen and learn about your teams, technologies, markets, and business models. Congratulations to YC W23.
In the below chart, we map the number of YC companies by batch over the past 10 years and the percentage of those companies that are tagged as B2B by YC. The W23 batch saw a remarkable increase in the focus on B2B, which kept us busy over the two days and which speaks to the scale and breadth of the opportunity in enterprise tech.
As with previous posts, we divide this post into two sections: 1) our favorite quotes and 2) the key themes and company descriptions.
