Our Story Behind the Club

Dear fellow entrepreneurs,I have to admit something: I’ve never enjoyed the superficial small talks that fill most networking events. As an INTJ, surface-level conversations drain me. They feel empty, and I often leave wondering why I showed up in the first place.The same goes for big, noisy conferences. Endless schedules, crowded rooms, and back-to-back sessions leave me exhausted. And honestly, I personally find it hard to absorb much in such settings. Sometimes these events feel more like photo opportunities than real learning.What’s more, I struggle to build genuine, lasting connections with like-minded people in those environments.So I asked myself: what if there were another way? A space where connections are meaningful, conversations run deep, and learning unfolds gradually—over weeks, months and years. That’s exactly what this club has become.We host monthly accountability roundtables to help you make consistent, sustainable progress. We bring together founders to share not just ideas and opportunities, but also struggles and lessons learned. And because entrepreneurship isn’t only about building companies—it’s also about building ourselves—we include leadership and well-being workshops alongside founder spotlights and frontier tech talks.I’ve seen so many of you struggle to find trustworthy support. I’ve heard how difficult it is to find a CTO, how urgent fundraising can feel, and how often burnout creeps in. That’s why we’re building an ecosystem—with mentors, coaches, scientists, investors, and other experts—so you don’t have to do this alone.We’re more than just a club—we’re a space where we grow together as entrepreneurs, as leaders, and as humans.Warmly,
Yuqing (Quin)
