Quiero hacer una prueba/locura.
Cobrar antes de publicar el sideproject.
Voy a permitir pagar una cuota anual ridícula, y luego iré aumentando el precio a medida que vaya publicando/desvelando cosas.
@jpaask precio con descuento para earlyusers.
Conseguir usuarios gratuitos ahora no implica que sean de de pago en un futuro. Eso no es validación de negocio.
Has de conseguir que saquen la tarjeta desde el minuto uno.
@jpaask ¿Que otro partido crees que quiere arreglar el destrozo?
Los partidos quieren mantener contentos a los que viven del estado (mayoría de votantes).
Reducir ayudas, pensiones o puestos de funcionarios no es una opción para ellos.
Una espiral de aumentar el gasto y hundir el país
@xoelipedes Para el votante medio, todo se arregla votando al otro, imprimiendo dinero, regalando ayudas a los míos y quitando cosas a "los malos del otro lado".
@xoelipedes Efecto Dunning-Kruger. El que menos sabe es el que más convencido está, porque no ve la complejidad. Cuanto más conocimiento tienes, más piensas en segundas y terceras derivadas, y más complejo lo ves todo. No eres el único pensándolo, tranquilo.
The Claude Code leak? You know already. The real risk is what comes after: unaudited cloned repos with bash access, and a supply chain attack on axios the same day. Here's why I run all my AI agents inside containers.

LaLiga has been ordering Spanish ISPs to block ~3000 IP addresses almost every weekend. Because Cloudflare IPs are shared, this has been doing massive collateral damage to thousands of legitimate websites, apps, and vital services - all at the whim of a private corporation.
Desarrollar un SaaS no es difícil.
Tener clientes sí lo es.
Las personas solo paga cuando tu SaaS:
→ elimina complejidad: hace simple algo que antes era técnico o tedioso
→ ahorra tiempo real: reduce pasos, automatiza tareas repetitivas
→ da claridad: convierte datos en decisiones obvias
→ reduce riesgos: evita errores, pérdidas o preocupaciones
→ permite crecer: escalar sin más caos ni más trabajo
→ genera ROI: gana dinero o ahorra costos de forma clara
Asegúrate de que el SaaS que estás creando
cumpla al menos uno de estos puntos
@devruso Tengo el mismo modelo pero el de 64gb de ram y cpu Ryzen AI 9 HX 370
Con kubuntu funciona el táctil, el sonido y la webcam.
La batería depende de para que lo uses, pero dura más de 2h ...
Única pega, los ventiladores a máxima potencia van a despegar.
Algunos hablan sin saber🤫
Last week, we shut down our startup.
This is how AI hype pushed us to $100k ARR, and then killed us 6 months later.
In 4,5 intense years, we raised $200k from incredible investors, went through pivot hell, and built Luca, an AI Running Coach on Whatsapp, hitting $100k ARR in a few months.
Then we set out to build the platform for Athletes/Gyms/Influencers to launch their branded AI Coaches. We even had a deal with a sports legend.
But soon after, we realized our AI bet was fundamentally wrong.
Here’s what we learned 👇
1️⃣ If your product must be right 100% of the time, you'll have a hard time
Even ChatGPT isn’t right 95% of the time - and it doesn’t matter. It still delivers huge value.
We had a 95% success rate in all interactions... but that meant one wrong workout per month. By the second one, trust was gone.
👉 Build for use cases where an intern could do it - or 95% success feels great.
2️⃣ The market is everything (Marc Andreessen was right)
We built complex workflows, guardrails, and prompt evaluations for 700 demanding users paying €10/month. 70k monthly interactions wtih 95% success rate. Still not enough.
I bet most AI B2B SaaS products aren’t much different. B2B just pays 10× better and sticks around.
3️⃣ Don’t make “AI” your marketing engine
Our hook worked while AI was new. Then hype faded… and it stopped working.
👉 Sell the solution, hide the AI
Leading with “AI” creates unrealistic expectations you’ll never meet.
Most users assume it’s perfect and that works against you.
4️⃣ Design for trust (reduce the black-box feeling)
When AI generates images, video, or code, you see results instantly, no trust needed.
With text-based products, show context, data, or sources to build credibility.
5️⃣ Don’t replace sympathetic jobs (this hardly applies to business owners cutting costs)
Users and microinfluencers with personal trainer friends resisted trying Luca.
6️⃣ Go international early
The US and English-speaking markets write the playbooks.
By the time something reaches Europe, it’s already crowded.
Our TikTok/IG microinfluencer strategy worked great in Spain ($4 CAC).
But abroad, the channel was owned by Runna. They’d started years earlier and had 35% of interesting microinfluencers on their payroll.
7️⃣ Don’t build proactive products on WhatsApp
AI on WhatsApp works great reactively (answering questions, receiving info).
But if your product is very proactive... you’ll drown in templates, costs, and translations.
We had 200+ templates and paid 2–3€/user/month. A nightmare for internationalization.
- Bonus: Short-form marketing really works.
Design your product with a marketing angle in mind (a visual hook, etc.).
It’s been 4,5 relentless years, mostly just Linos (CTO) and me, doing everything.
The result is hard to swallow:
years of effort, savings, and belief that ended up in nothing.
Even harder knowing friends and such great investors trusted us with their time and money.
But we’re proud of what we built and learned. And if this helps anyone, it was worth it.
For now, Linos and I are exploring new opportunities. Each of us wants to dive into new problems, new industries, and contribute our skills to other projects.
👇 If you’re building in AI or want to chat, explore opportunities or collaborate (AI product / GTM / growth), or just exchange notes, happy to chat.
