Where To Find Emerging Product Voices on Substack?
You join Substack to find your people.
The thinkers, the builders. Fellow maniacs who ship at midnight and write about it at 2am.
But Substack’s search algorithm - for obvious reasons - prioritizes results based on page rank, so you find world-famous newsletters so established you were already subscribed - twice - on two different email addresses.
They’re brilliant- but they don’t feel like someone you’d DM a half-baked demo for feedback.
(Side note: we delivered this feedback in this post for the Substack Team.)
Searching for ‘‘AI’’ doesn’t help either. At this point it’s harder to find a newsletter without AI in the title.
Welcome to my first 2 weeks on Substack.
So I did what any product person would do: I made a list.
Then I shared the list and it became an instant hit.
So I promised to release a fresh version every 3 months. Here’s Episode 2.
Who You’ll Find in This List
Product People of Substack includes authors who write about:
Building meaningful, trusted products
Building with AI
How AI is reshaping how we design
How AI is reshaping how we ship
How AI is reshaping how we market
How AI is reshaping our careers while we’re busy doing all that
In other words, it’s not just tech commentary.
It’s tech lived and questioned.
How This List Travels The Internet
I created a GitHub repo for the lists, so anyone can browse, fork, or remix them freely. Each edition lives there, along with submission links and update logs.
The list also lives on StackShelf because - of course.
I’ll also be sharing it on AI Vanguard Society. Michael Spencer (AI Supremacy) is driving this new space, join if you’re into AI.
Last but not least: the list is shared via our Community Chat with two extra perks:
you’ll see which writers vibecode / code
you’ll see which writers are happy to recommend a fellow builder. Reach out to them, I’d love for you to support each other.
👉 You can pass along either version to make it ridiculously easy for new readers to discover brilliant product minds.
How This List Works
⚡️ The list isn’t ranked or sorted - and that’s intentional. ⚡️
No filters, no auto-sorting by subscriber count. Because I want you to give everyone’s words a fair shot before letting metrics decide for you.
Subscriber count is not always a proxy for usefulness.
And some of the best writers are just getting started.
The List: Product People of Substack
Now - our community is growing fast, so the list is looooong.
But if you’re a builder at heart, investing 20 minutes of your time to follow ALL these amazing people is the fastest way to grow a strong community around you:
AI - the Deep, the Curious and the Fun by Ursula Maria Mayer
Kenny - Your Freelance Friend by Kenny - Your Freelance Friend
The Product Philosopher by Dutch DeVries
