👋 Hey, I’m Karo

AI Product Manager, Substack Bestseller and someone who believes in testing before tweeting.

I run a fast-growing newsletter and community for thousands of builders, founders, and creators exploring the wild frontiers of AI, product, design and vibecoding.

Must have:

• A clear list of expected outcomes

• the ability to test the product as both a free and premium user (e.g. via a temporary discount code).

Optional:

• Brands who reward my readers with unique perks see higher engagement and stronger results.

• Enjoy a 50% discount when you share my writing with your audience; just commit to reposting on your own site/blog.

Step 1: Please send your request. If needed, I’ll reach out with clarifying questions.

Step 2: I review and either approve or recommend a better-suited creator.
Step 3: If approved, you'll receive a booking confirmation.
Step 4: Once booked, you provide relevant assets, I complete the testing and send you a draft.

Step 5: The blog post goes live on the agreed date, and I share the engagement stats.
