🚨 The B2B marketplace you’ve never heard of — solving fashion’s $500B problem.

Josh Kaplan went from fashion founder to reinventing how brands offload excess inventory.

Today, he’s co-CEO of Ghost, one of LA’s fastest-growing startups — and the secret backend for how brands like Levi’s, Vans, and Express manage their surplus stock. 🛍️📦

🎙️ We sat down with Josh to break down how he’s digitizing one of the last analog industries — and why tech adoption in fashion is way harder than it looks.

🔍 What you’ll learn in this episode:

🧵 How COVID exposed critical cracks in the global supply chain — and led to Ghost

🦄 Why you should always pitch for Partners and not for Funds

📉 Why excess inventory is fashion’s most ignored profit leak

🗽 The playbook Josh used to get a student startup on a Times Square billboard

📬 How to cold email as a student and get Fortune 500 execs to respond

🔁 Lessons from building both sides of a two-sided marketplace — twice

🚀 What most founders get wrong about B2B marketplaces

💡 Plus:

The founder mindset of "always building" — and why Josh plans to launch again even after a big exit.

🔁 Repost if it made you think. This one’s for the builders.

This might be the most insane AI founder story you’ll hear all year.

Dropped out of high school.

Met the Queen of England. 👑

Helped pivot Instabase by building a transformer before it was cool.

Now? He’s building a foundation model for the human mind — and raised from a16z, Menlo, and Benchmark.

🎙️ We sat down with Daniel Reid Cahn, cofounder & CEO of Slingshot AI, to unpack how he’s using AI to reinvent mental health — without replacing human therapists.

🔍 What we cover:

• Why the future of therapy isn’t GPT wrappers — it's foundation models for psychology
• How Daniel raised millions pre-PMF from top-tier VCs
• Why LLMs are perfectly suited (and dangerously close) to handling our deepest thoughts
• What it really takes to hire top-tier AI and psych talent
• Building a bi-continental company across the US & UK from Day 1
• Why AI therapy could compete with psychedelics — and what keeps Daniel up at night
• The truth about defensibility in AI today: data, distribution… or something else?

💡 Plus:

His founder playbook, ethical design principles, investor tactics, and what he’d do if launching from scratch today.

This is not your average AI story.

It’s raw, smart, and brutally honest.
