"We believe personal intelligence you own will become the foundation for an entirely new consumer ecosystem.
Every device will give the same intelligence a deeper understanding of your life or a new way to help you. Core is the first step towards it."
🔥
We believe an ecosystem will grow around personal intelligence you own.
We’re building it at @ghostai.

"Imagine an earring that whispers helpful tips in your ear: “Better for you to set the learning rate to 0.00251342.” Good results are no longer in question; with a Whatever Agent Ultra Max subscription, you never come to a meeting short on quantitative results or new experimental ideas...
In the original story, the earring’s advice is always right, and the people who wear it live remarkably successful lives. But when they die, the part of their brain responsible for deliberation has withered from disuse.."

I strongly believe any company can be absurdly effective
You just have to load “no” as your default answer. No, no, no, okay fuck yes
Had a lot of fun sitting down with Nakul and spilling our secrets
Railway started the year at $20M ARR. It’s now ~$100M. Solo founder. Fully remote. Only ~40 people.
The one trait that explains why Railway is breaking all the rules:
“It’s almost like cheating on your homework when you go and look at somebody else’s solution. If this is how Stripe does this or this is how Cursor does this, I don’t want to hear about it.”

"to me it's almost like cheating on your homework when you go and look at somebody else's solution. you pollute your own brain with whatever that is."
love @JustJake's point around ignoring conventional playbooks as he builds @Railway. yet another great listen by KnuckleUp.

met Zain in December after my colleagues Max and Nakul pulled me in mid-meeting. Zain stayed an extra 30 minutes and we invested shortly after. rare to meet someone who has accomplished so much early on in life and is just scratching the surface.
congrats to Zain and the entire @ghostai team on the launch of Core! excited to be part of your journey.

“Message market fit is when you have people signing up. Product market fit is when they retain.”
Juicebox got 30,000 signups in 3 days. Then came six brutal months getting the product to actually work.
David Paffenholz. Co-founder and CEO of Juicebox.
Started the company at 21. 90 employees, 5K+ customers today. Bet on getting search right first while competitors tried to build the entire “AI recruiter.”
