Theresia Gouw, co-founder of Aspect Ventures, and Sukhinder Singh Cassidy, president of StubHub, are the definition of friendship goals. The power duo started working together in 1999, and have been building each other up\u2014as well as other women in Silicon Valley\u2014ever since. The two spoke candidly about what it\u2019s like to work with a close friend in a conversation with CNN\u2019s Kate Bolduan at Marie Claire\u2019s Power Trip conference, an exclusive two-day event in San Francisco.How Gouw and Singh Cassidy met isn't unusual for women in tech. Gouw was working in venture capital at Accel, and Singh Cassidy, then the co-founder of software company Yodlee, was looking for an investment. \u201cWe noticed each other as the only women in the room. Not just that day, but in that whole year,\u201d says Gouw. Accel Partners ended up investing in Yodlee, and thus \u201cbegan the work friendship,\u201d explains Gouw. Their paths would cross again during Singh Cassidy\u2019s stint at Google. \u201cWhen I was at Google many years later, Theresia started pitching me for whatever I was doing next,\u201d recalls Singh Cassidy. \u201cWhen it came time for me to leave Google, I went to Accel because of Theresia. She invested in my next company.\u201d Despite the trope that working with close friends can get tricky, both women maintain that their partnership has actually been beneficial for business. \u201cI think that there are some huge benefits to going into business with somebody you\u2019ve known for a long time,\u201d says Gouw. \u201cYou have that level of trust within one another. It allows you to have a much more honest, deeper discussion around problems.\u201dSingh Cassidy agrees\u2014especially in the cutthroat world of Silicon Valley, she says, female friendship in the industry is key to success. \u201cI think that the Valley can be very transactional,\u201d she says. \u201cThe benefit of having a relationship is, even at tough moments, it causes you to be more candid and respectful.\u201dEven when trying out new things, the two continued to lean on each other. When Singh Cassidy left Accel for a job at Polyvore and it didn\u2019t work out, Gouw still showed unwavering support. \u201cI took a job that she didn\u2019t agree with. I took a job that was funded by another VC,\u201d says Singh Cassidy. \u201cSix months later, I was back crying on her shoulder. I appreciated the candid perspective.\u201dThe pair are united in a common goal: To create more and better opportunities for women in tech and venture capital, two predominately male-run industries (Gouw is also a founding member of All Raise, a nonprofit driven to create more opportunities for women and people of color in venture capital). With only 3 percent of all venture capital going to female-founded companies, and considering the bro culture that controls much of the tech industry, it's voices and partnerships like Gouw's and Singh Cassidy's that are needed to change the narrative.
