AI storytelling for families
Show Notes
When Ricardo Vice Santos was at Spotify in the early days, he noticed something nobody was talking about out loud. People were uploading birthday songs with your name in the title. “Happy Birthday Ryan.” “Ryan, You Look Good Today.” Hundreds of them. And he started asking a question that would take him fifteen years to fully answer: what if Beyonce could sing a song made specifically for you?
That question became an obsession. It followed him through Spotify's growth years, through a nutrition company, through a preventive health scanner startup called Neko Health, and eventually landed him at dreamstories.ai - an agentic content studio built on one beautifully simple premise. Your kid is the hero. Every page. Beautifully illustrated. Printed and shipped to your door.
Nearly 100,000 books sold. A team of seven. And a vision that makes most AI founders look like they're thinking too small.
The Organizing Idea: End-of-One at Scale
Ricardo's entire career can be understood through one organizing idea: deliver something that feels one-on-one, at scale. He did it in music discovery at Spotify. He did it in nutrition. He did it in preventive health. Now he's doing it in media, starting with the most emotionally charged content category on the planet - the books parents read to their kids at night.
The insight is not just that personalization is nice. It is that personalization, when done at the right layer of the stack, changes the entire economic structure of a category.
- •Physical goods command real prices in a world where digital content trends toward free.
- •Personalized books become repeat purchases, not one-time novelties.
- •The episodic format converts a gift into a subscription behavior without the consumer ever thinking of it that way.
- •The creation experience itself is part of the product, not just a means to an end.

End-of-One at Scale
The organizing principle behind Ricardo's entire career: make every customer feel like the product was made specifically for them, while the unit economics work at scale.
- •Personalization is not a feature - it is the product. It changes what a customer is willing to pay and how often they return.
- •Physical goods with personalization resist the gravity toward zero that pulls all digital content.
- •The creation experience and the final artifact are both part of the product. Designing only one of them leaves value on the table.
- •When personalization is structural, not cosmetic, it creates defensibility that generic content platforms cannot replicate.
The Agency Spectrum Model
A framework for understanding where your target customer falls between passive consumption and active creation - and designing your product for the underserved middle.
- •Passive consumers want content delivered. Active creators want full tools. The majority sit in between: they would create if you made it easy enough.
- •Roblox cracked this for gaming. dreamstories.ai is cracking it for personalized storytelling.
- •The product today starts with templates. The product tomorrow is an open creative platform.
- •Character consistency across pages is harder than it looks, and that technical difficulty is a meaningful competitive moat.
The Episodic Subscription Unlock
Most personalized book companies sell once or twice a year around holidays. Ricardo recognized that pattern as a ceiling, not a floor.
- •The episodic structure means every book sets up the next one - the story does not end, it continues.
- •Kids grow. Stories should grow with them. Parents notice fast when the character is no longer the right age.
- •Retention is driven by the child's desire to re-read and the parent's desire to never read Goodnight Moon again.
- •Cart values from cold paid acquisition surprised even Ricardo himself - the emotional stakes of the category command premium pricing.
Founder Experiment: Build a Character Consistency Pipeline
Ricardo's core technical moat is the proprietary pipeline that keeps a specific face looking like itself across multiple illustrated pages - a problem that sounds simple and turns out to be surprisingly hard. Here is how to experience it firsthand using Cursor or Replit.
- 1Take a reference photo. Use your own face or a stock image with a clear, well-lit portrait.
- 2Use a model like Flux or SDXL to generate three character variations from that reference - different angles, different expressions, different illustrated styles.
- 3Attempt to maintain character consistency across a four-panel sequential story. Each panel should show the same character doing something different.
- 4Your job is not to get it perfect. Your job is to measure how fast the likeness degrades across panels, and which prompt engineering techniques slow that degradation.
- 5Document your findings: which prompting approaches held consistency longest, which model settings had the most impact, and what the failure modes look like.
Why this matters: Experiencing character consistency degradation firsthand changes how you think about the moat in any personalized media business. The pipeline Ricardo built at the infrastructure level is what separates dreamstories.ai from any competitor who tries to replicate the product with off-the-shelf tools.
