Positions count by year

Hover over a name to see the position and date range. This table only includes positions where at least the start date is known. The positions count can count the same person multiple times if they held different positions; similarly, the list of staff may include the same person multiple times if they held more than one position during a single year. For each year, a person is included if they were at the organization for any part of the year; this means the actual staff count at any point during the year can be lower (or higher, if some staff held multiple positions in a single year).

Number of full-time staff at the beginning each year

The following table lists some dates and people who were at the organization on the given date (namely, the start of the year). The table may not list every person who worked for the organization (e.g. they could have joined and left in the middle of a single year). This table excludes associates, interns, advisors, and board members.

Full history of additions and subtractions

This table shows the full change history of positions. Each row corresponds to at least one addition or removal of a position. Additions are in green and subtractions are in red. If a position name changed, it is listed simultaneously as an addition (of the new name) and removal (of the old name) and colored yellow. Additionally there are faded variants of each color for visited links.
