We don’t have a pitch deck.
We’re not raising.
We don’t even really sell.
Everything we’ve accomplished at The Nucleus Network has grown from one thing:
Trust.
People vouching for us in rooms we’re not in.
Friends texting friends:
“You should talk to Nucleus.”
“They’ll make the right introduction.”
“Jake’s your guy.”
Warm introductions > cold outreach
Stop what you’re doing!!
Take 30 seconds to be grateful for what you have.
Then keep going.
Important ‼️
Had a meaningful conversation with a friend about how much better life has become since he’s focused on hanging around people who are positive not negative.
Couldn’t agree more!
Just wired angel investments into two incredible founders building amazing companies…
More to come next week
People just make things happen in NYC.
It’s heard to explain.
The energy is contagious.
I always aim to bring that energy back to LA.

No matter your opinions on the aftermath of that day…
We are all human and that day was one of the worst days in modern history.
Never forget!
Daniel is on our board at Nucleus.
So impressed and happy for him!
Today I am introducing @suprette_.
For generations, the heart of French village society revolved around supérettes, small neighborhood markets that served as cultural anchors where people gathered, connected and lived daily life together. Places like that matter more now than ever.
These neighborhood pillars provided the inspiration not just for our name, but for our broader thesis as well. With so many aspects of business and life, from technology to content to intelligence, becoming increasingly commoditized, value is moving swiftly to what can't be replicated.
This is why we exist.
We are operators first. We identify and partner with a small number of exceptional businesses, take meaningful ownership, and embed ourselves alongside their teams, bringing capital, talent and technology to the work. We protect what makes them special and strengthen everything behind the business.
We recognize that capital alone won't unlock that potential. These businesses are built on taste, craft, quality and authenticity. Scaling them takes people who understand how they actually work.
The businesses behind these experiences, across hospitality, events, sports, and health and wellness, share qualities that are rare and durable. They create real-world connection and cultural resonance. Demand is rooted in ritual and identity, not algorithms. Technology sharpens rather than disrupting them. The experience remains deeply human, while everything behind it becomes smarter, stronger and more efficient.
Today’s cultural anchors look different than the traditional supérette, but they matter more now than ever. Our focus is finding those businesses that communities form around and where their value compounds with every experience.
In a world of infinite supply, that scarcity only becomes more valuable. We are building the cultural infrastructure of real life.

“Why are you investing in so many CPG companies?”
You can’t make AI hummus, AI pickles, AI supplements etc.
Also CPG founders are the best
