Great ideas rarely emerge from isolation

South Park Commons is a community of technologists ideating and validating what to build next. We believe this shouldn’t be done alone. Our members range from exited founders and highly-cited researchers to new graduates and first-time entrepreneurs. What unites us is ambition, ability, and a mutual commitment to helping each other navigate -1 to 0.

Mikhail
Waterloo and Google taught me engineering, while my journey to world championships in skydiving taught me human nature, high performance and leadership. I'm an explorer at heart and love the questions: "is it possible?" and "can we do it?"
Feross
Founder & CEO of Socket. Socket helps companies defend their systems against open-source software supply chain attacks. We're growing fast and hiring!
Kevin
I'm working on an AI media company. Think Fox News / MSNBC but driven fully by AI, and distributed on modern platforms like TikTok. Previously, I started a web-scale crawler that I sold in 2022. I also do standup comedy and anything outdoors.
Mike
Founded Skip (YC W18) now working on something new. Terrestrial and Internet Explorer.
Feng
Do crabs think fish can fly? I’m Yan (go by my last name), just moved to SF post-Duke CS. Building weirdly fun stuff, training for triathlons, and dreaming of octopus-level sensing. Let’s jam on wild ideas—ideally mid-run, ride, bball, or dance break?
Sam
Building Sentience...
Rebecca
I’ve lived inside the finance function my entire career - from ex-big 4er to in-house finance leader. I’ve built finance teams and systems from the ground up, led complex migrations, and battled the broken workflows that define today’s finance tech stack. I’ve seen the pain from every angle: as a service provider, a builder, and a user. Founders chase product-market fit. I am the validation of the problem, and the founder-market fit. I'm not just building software; I’m rebuilding the infrastructure I wish I had. As an ex-accountant turned founder, I’m on a mission to modernize the back office and deliver an all-in-one AI finance platform that replaces fragmentation with clarity, speed, and automation.
Jason
Co-founder and CEO of Storytime, focused on building new ways to engage audiences through audio. Former Head of Partnerships at Expo and a long-time builder and educator at Stanford.
Guglielmo
Co-founder of Adjoint, Inc. Previously working on system-level autonomy at NASA/JPL, and got my Ph.D. in aerospace engineering from Polytechnic of Turin.
