The tech sector may be known for the rapid adoption of change, but I confess I was surprised to see the short amount of time it has taken for women’s representation in the boardrooms of Silicon Valley to go way up.
Currently women directors fill 23% of the board seats on the Lonergan SV150. Compared to our study of Silicon Valley boards published in the 2015 Who Runs Silicon Valley Board edition, this is an increase of nine percentage points.
SV150 Board Membership over Time
Summer 2015 | Summer 2018 | Summer 2019 | |
---|---|---|---|
SV150 board seats | 1100 | 1250 | 1310 |
Women filled board seats | 157 | 237 | 307 |
Percent women filled board seats | 14% | 19% | 23% |
Number boards with no women members | 45 | 24 | 7 |
Source: Lonergan Partners 2015 Who Runs Silicon Valley board report and the Lonergan SV150 annual analysis 2018 – 19; board composition data was sourced both from company websites and proxy information. 2015 board data above adjusted to include all 150 companies of the Mercury News SV150 (reported data in summer 2015 excluded six acquired companies).
This rapid change in part reflects the impact of legislation passed in 2018, requiring public companies headquartered in California to have at least one woman on the board by the end of 2019. This requirement steps up so that by the end of 2021, these boards will need at least three women directors. However, our tracking shows the movement began well before the 2018 legislation was passed.
Some other highlights from our research:
The increase in women-filled board seats since 2015 (150 seats) represents 71% of the total increase in board seats (210 seats). This is consistent with my observation in working with boards that they have reacted to the current challenge in two ways: filling seats coming vacant with women, and even more often adding women-filled seats to the board.
Other key statistics we have found in our research:
Larger Companies have more women in the boardroom
Company Group | Average Board Size | Average # Women Directors | Percentage Women |

All SV150 | 8.8 | 2.0 | 23% |
Top 50 | 10.1 | 2.6 | 26% |
Middle 50 | 8.3 | 1.9 | 23% |
Bottom 50 | 7.9 | 1.6 | 20% |
Note: ranking based on 2018 sales
Women CEOs serve with more women directors than male CEOs
Company Group | Average Board Size | Average # Women Directors | Percentage Women |
---|---|---|---|
All SV150 | 8.8 | 2.0 | 23% |
Women CEOs only | 9.4 | 3.3 | 35% |
Women CEOs only (excluding the CEO) | 8.7 | 2.0 | 23% |
Men CEOs only | 8.4 | 2.3 | 27% |
Note: average board size includes the CEO except where noted; board population was sourced in May 2019.
These rapid changes to board gender diversity have clearly required significant board time and effort. None of this change is easy, especially when Silicon Valley boards appear to be looking for new talent en masse.
