Interesting trends that pop out at first glance:
1. Seems like YC is all aboard the B2B SaaS train. This is funny because early last decade B2B SaaS was known as mostly a lifestyle business category, while investors focused on consumer facing tech and big ticket enterprise products
2. It appears that the big tech employee track and the startup track are one and the same now. This flies in the face of the common wisdom that entrepreneurs and employees are very different from one another.
