The Full Story

TL;DR

Victor Perez y Diego Rodriguez rechazaron becas del Rey de España en Cornell para construir Krea AI. Una demostración en localhost publicada en Twitter generó $10K en suscripciones en 24 horas. Crecieron a 20M usuarios con solo 8 personas.

Victor Perez y Diego Rodriguez se conocieron como estudiantes de pregrado en Barcelona a principios de los 2010, estudiando ingeniería de sistemas audiovisuales. Diego introdujo a Victor a la codificación y redes generativas adversarias, y Victor pasó los siguientes seis años trabajando en modelos generativos, incluyendo trabajo temprano en ArtBreeder.

Rechazando una beca real

Después de graduarse, ambos recibieron becas completas del Rey de España para asistir a la Universidad de Cornell. Victor estuvo en Cornell exactamente un día — ya estaba soñando con lo que se convertiría en Krea. La pareja rechazó sus becas de posgrado para construir la startup en su lugar.

La aplicación accidental

Diego solicitó a HF0 (un programa de residencia anunciado como "YC para fundadores técnicos") usando el concepto de Victor — sin decirle. Cuando HF0 llamó a Diego a Miami para una entrevista final, confesó lo que había hecho. Victor le dijo que "vendiera como el demonio esta cosa". Menos de 72 horas después, ambos estaban en Miami. A pesar de una mala entrevista, obtuvieron la oferta. Fundaron Krea en marzo de 2022.

La demostración en Localhost de $10K

El momento de ruptura del producto llegó cuando Victor armó rápidamente una demostración de lienzo con IA en tiempo real en una cena usando un Latent Consistency Model. Cuando el equipo publicó esta demostración en Twitter (ejecutándose en localhost), las personas asumieron que era en vivo y comenzaron a suscribirse inmediatamente — hicieron $10,000 en suscripciones en menos de 24 horas antes de que el producto estuviera disponible públicamente.

20M usuarios, 8 personas, una sala de estar

Para abril de 2025, Krea había crecido a más de 20 millones de usuarios completamente de forma orgánica, multiplicado por 20 sus ingresos, y recaudó $83M con una valoración de $500M — todo con un equipo de solo 8 personas trabajando desde una sala de estar en San Francisco. Su lista de clientes incluye Pixar, LEGO, Samsung y Perplexity.

Fundada: Marzo de 2022 (residencia HF0)
$10K en 24 horas: De una demostración en localhost publicada en Twitter
Usuarios: 20M+ (todos orgánicos)
Ingresos: Crecimiento 20x en 14 meses, $8M ARR (abril de 2025)
Equipo: 8 personas (oficina en sala de estar)
Financiamiento: $83M total ($47M Serie B de Bain Capital)
Valoración: $500M
Clientes: Pixar, LEGO, Samsung, Perplexity

Key Takeaways

Rechaza todo por la oportunidad correcta — declinar becas del Rey de España para construir una startup requiere convicción

Una demostración en localhost que se vuelve viral es la señal de product-market fit definitiva — $10K antes del lanzamiento

Mantenerse pequeño (8 personas, oficina en sala de estar) mientras sirves a 20M usuarios crea una eficiencia de capital extraordinaria

Construye para creativos, no para ingenieros — "Python no es la mejor interfaz para usar IA creativamente"

The journey, decisions, and context behind this milestone

How Victor actually did it

6/7 funnel stages sourced

Reconstructed from Victor's own published sources. Quoted claims are the founder's words, verified verbatim; anything marked as our analysis is exactly that.

Where the idea came from

Personal painPivot from A free search engine over Stable Diffusion prompts and generations at krea.ai, plus an open knowledge base of prompt modifiers, before real-time generation became the product4y domain experience

Krea came out of the founders' own frustration with creating. Victor had been building generative models for years and was working on a way to interact with AI directly in the browser; Diego applied to the HF0 residency with that idea without telling him, and the residency offer turned it into a company.

“KREA was born out of a frustration to create”

Cerebral Valley Deep Dive: co-founder Diego Rodriguez Q&A

Validation

MvpInconclusive

Built a new prompting interface on top of their Stable Diffusion prompt knowledge base and put it in front of beta testers, with a walkthrough video for early users and an open request for feedback.

The founders announced in their own newsletter that the new interface had gone out to beta testers. They did not report what the testers concluded.

“we implemented the new interface and started to share it with beta testers”

The Prompter #003 (krea.ai newsletter)

MvpValidated

Victor built a real-time generation prototype from a paper published 24 hours earlier and wired it to a webcam for a Krea Dinner, a private gathering the founders hosted for artists and engineers. Guests watched the camera instead of each other, and the founders read that as demand.

The founders treated the guests' reaction at the dinner as the signal to ship the prototype as a product.

“When we saw how people were paying more attention to the camera than the guests”

Cerebral Valley Deep Dive: co-founder Diego Rodriguez Q&A

PresalesValidated

Posted a tweet demoing the real-time tool while it was still running on localhost. Viewers assumed the tool was already live and subscribed for what they believed was priority access.

The demo tweet produced $10,000 of subscriptions in under a day, before the tool was available.

“In less than a day, we made $10,000 in subscriptions”

Cerebral Valley Deep Dive: co-founder Diego Rodriguez Q&A

First test users

UnknownFree testers

The earliest testers documented by the founders are the beta testers they shared the new prompting interface with in August 2022, announced through their own newsletter. Where those testers came from is not stated anywhere we could find.

“here’s the video we shared our early users explaining how it works”

The Prompter #003 (krea.ai newsletter)

First paying customer

Existing audiencePresale

The only paying-conversion event the founders describe is the localhost demo tweet: viewers believed the tool was already shipped and subscribed to secure early access. Note that the founders do not say these were Krea's first paying users ever, only that this burst is where they concluded creatives wanted the product.

“People thought it was already available and started subscribing just because they thought they’d get priority access”

Cerebral Valley Deep Dive: co-founder Diego Rodriguez Q&A

Acquisition channels, and whether they worked

Twitter / X · @krea_ai demo video of the unreleased real-time toolFirst customersWorked

They filmed the real-time tool running on their own machine and posted it as a demo, before it existed as a product anyone could use.

“We did a tweet showing what the KREA Realtime tool would look like (it was running on localhost)”

Cerebral Valley Deep Dive: co-founder Diego Rodriguez Q&A

The demo read as a shipped product rather than a prototype, so viewers subscribed to get in ahead of everyone else.

“People thought it was already available and started subscribing just because they thought they’d get priority access”

Cerebral Valley Deep Dive: co-founder Diego Rodriguez Q&A

Word of MouthScalingWorked

The founders describe the growth to over 20 million users as organic and mention no paid acquisition anywhere in the Series B post. Reading that as word of mouth is our mapping, not their word.

What broke as they grew

Team size was capped on purpose rather than by demand. Close to a million users were served by five full-time people, the founders named twelve as the target size, and candidates typically worked with them for weeks or months before joining.
