The cost of starting a company used to be $5 million. Then $500,000. Then $50,000. Now it is closer to $500. The only expensive thing left is your unwillingness/fear to begin.

The LatAm Global Founder Era

“Then came our Ronaldos and our Messis: @rauchg at Vercel, @hdubugras & @pedroh96 at Brex, @LuisvonAhn at Duolingo, @woloski & Eugenio at Auth0. The first ones that moved to the US, competed in the Champions League of tech, and succeeded.

Now, a new wave is arriving: @luanalopeslara at Kalshi, @c_valenzuelab at Runway, @victorcardenas at Slash, and many others. A new vintage of LatAm-born founders, global from day one.”

FENÓMENO BARRIAL

[immad @immad]

Every VC had a reason Vercel shouldn't exist.

Guillermo Rauch heard a different reason from every investor he spoke to when building Vercel, and he kept going anyway.

He joined us live at Mercury HQ in SF for Founders in Arms, and this was one of the sharpest moments in the conversation: the idea that consensus is a signal to walk away, not lean in.

Full conversation with Guillermo Rauch (CEO, Vercel) on the latest Founders in Arms episode. Link in bio.

🎙️@rauchg CON NAVAL: 15 FRASES POTENTES

“La tarea del ingeniero se está convirtiendo en otra cosa”

“Estoy completamente obsesionado con esta idea de fábricas de software”

“Ahora ya no evalúo si alguien produce una tarea. Evalúo si construye la fábrica que multiplica resultados”

“Antes se hablaba de ingenieros 10x. Ahora claramente existen ingenieros 100x o 1000x”

“La calidad del re-prompting es extremadamente importante”

“Los modelos dejaron de ser ingenieros junior. Ahora son ingenieros principales”

“Respeto mucho más a los modelos como pares intelectuales”

“El ser humano todavía completa al modelo. La pregunta es cuándo va a pasar al revés”

“La web se está volviendo nativa para agentes”

“La categoría de software de infraestructura y bloques reutilizables para agentes va a ser extremadamente valiosa”

“No querés gastar un trillón de tokens recreando algo que ya existe”

“Cualquiera que entienda APIs, flujos de datos e inputs y outputs ya tiene una ventaja enorme”

“Un buen líder de ingeniería ya hacía vibe coding con personas. Ahora hacemos lo mismo, pero con agentes”

“Los modelos ahora vuelven con trade-offs y decisiones arquitectónicas”

“Lo realmente impresionante es cuando el modelo te dice: ‘No, no uses eso. Hay una mejor arquitectura para este problema’”

Sam Altman reveals why he no longer believes universal basic income is the answer to AI

"I used to be really excited about universal basic income, where you just give everybody money. I still am kind of excited about that. But I think people really need agency"

"If you just say AI is going to do everything and everybody gets a dividend, it's not going to feel good, and I don't think it would actually be good for people"

"I don't just want a check every month. What I'd want is an ownership share in whatever the AI creates, so I feel like I'm participating in this thing that's going to compound and get more valuable over time"

"So I sort of like universal basic wealth better than universal basic income"

Hace un tiempo nos preguntamos cómo podíamos hacer algo más por el ecosistema tech argentino. No como servicio, sino como comunidad.

La respuesta fue @premiostech_la: una premiación presencial para startups early stage que resuelven problemas reales con tecnología. Un espacio para dar visibilidad a los que construyen en silencio, cuando todavía nadie está mirando.

Lo organizamos junto a @FardoAI y el consejo de aliados. Una noche diseñada para que también puedas ganar desde las conversaciones.

Hoy lanzamos la página. Las postulaciones abren pronto. Si estás construyendo algo que vale la pena, o conocés una startup que merece estar en el mapa, este es el lugar.

Elon casually suggested Neuralink could eventually give humans a “math co-processor.”

Which is an absolutely insane sentence to read in 2026.

His point is actually interesting though:
human brains never evolved specifically for advanced mathematics.
AI systems basically did.

So Neuralink potentially adding direct computational assistance to human thinking starts sounding less like sci-fi and more like cognitive hardware expansion.

Human brains may eventually get upgrades.

Show me the thing you’ve built with AI you’re most proud of. Reply with a working product URL and what model / agent you primarily used.

[Jon Hernandez @JonhernandezIA]

“Today’s AI is the flip phone era.”

Sundar Pichai, CEO of Google and Alphabet, says today’s AI models will look primitive in just 3 years.

Agents will become normal, interfaces will fade, and content will move from any format to any format.

@vercel se suma como sponsor para el 6 de junio y eso nos tiene muy contentos. Ahora vamos a poder construir sin restricciones para dar una mano a quienes más lo necesitan.

Gracias y bienvenida a una iniciativa de impacto social en el mundo tech 🙌

@SpaceX is NOT just a rocket company. There's no one close to building what Elon has achieved. The implications for our world will be MONUMENTAL.

Nadie miraba hacia donde más importa: los que construyen sin red, apostando a que el problema que encontraron vale la pena resolver.
