"This network is the most engaged, thoughtful, responsive professional network I've encountered. I have gone to folks for everything from financial modeling help to growth hacker recommendations to offsite planning needs. The group feels like an extension of my Hummingbird coworkers in the frequency with which I contact them and trust I feel in their responses" CoS, Hummingbird

"The CoS Mastermind network and its programs at Primary Ventures is meticulously well curated (thanks to the relentless efforts of Gina and team). From carefully planned workshop sessions to open office hours, CoS Mastermind has provided many opportunities for professional and personal growth and, most importantly, has connected me with quality friends, mentors, and colleagues who will be a part of my network for a lifetime. Beyond the Mastermind network itself, the Primary Ventures team is incredibly dedicated at providing valuable introductions to a wide range of professionals. You’re in good hands once you’re a part of the Primary Venture network." CoS, Ro

"It’s been incredible to see this network scale so fast so successfully. The Chief of Staff role can feel like a Team of One at times, so having this network of tremendously competent and supportive individuals to collaborate with has been invaluable!
