Founded by Drew Houston and Arash Ferdowsi, Dropbox’s first employees consisted mostly of MIT Computer Science majors who either graduated or left to join the company. They are diverse racially, but entirely male. Since Dropbox’s industry, cloud computing, may not have been super “sexy” at the time, it is clear that they valued technical ability above all else. They hired the most talented developers they could find, which was crucial to building a high-quality product.
Without actively recruiting those outside the MIT network (for the most part), or actively recruiting women, the company has found it difficult to create a welcoming culture for a more diverse crowd, even today, with their number of female hires still notoriously below average. Notable exceptions to the “MIT crowd” include Jon Ying, who drew the now famous “Psychobox” for the 404 error page and became the company’s first designer. There’s also Michael Nagy, who was much older, a teacher by trade, and joined as their first technical support engineer.
