🥈 Second place at @ProjectEurope_ Barcelona, Cala's "Wolf of Wall Street" track. The brief: rewind 365 days, $1M to deploy, beat S&P 500 buy-and-hold on a live leaderboard. Most teams put the LLM in the driver's seat. We didn't. Here's how we built it 👇

Free dinner tonight! 🍔 Thanks @itstuyo

Great talk with Jesús Santos on Arc risk & Paulo Rodríguez being an absolute crack in sales and GTM. All at the @shakersworks officies!

for the folks who know ball

@GuliMoreno @matiii @exp8fellowship @matiii this has to happen 🔥

@matiii If you're up for it, happy to do an @exp8fellowship fireside for the 100 best young engineers in Madrid! 🔥 Can find a cool spot!

I’ll be in Madrid, Warsaw, and Paris over the next two weeks. If you’re nearby and want to help us double down on Europe and build locally across the region, let me know - would love to meet!

@inigodelasantas Check DM!

@aleexlopezg ¡Brutal! Me encantaría ver la demo 🙋🏻‍♂️🙏

Wrote about our experience at Project Europe on my Substack; the architecture, what we built, and what actually surprised us! alexlopezg.substack.com/p/we-finished-…

Jose Ramon Perez Aguera, CTO/CPO de @Mercadona Tech, sobre cómo reemplazaron Algolia (€9-15k/mes) por un desarrollo propio para la web de Mercadona 29 decisiones técnicas que la IA no tomó. Las tomó un equipo con experiencia. El resultado: +85% de mejora en ranking, 0% búsquedas sin resultados (antes 4%), y de $9-15K/mes a menos de $900/mes.

Leaving the hack aside, the best part was the space itself. Builders, founders, investors, deep talks randomly at 3am. Thanks to cala, @itnig , @exp8fellowship and to the rest of the companies that made the whole thing possible. The Spanish AI ecosystem needs more of this.

4/ It selects the final weights by maximizing expected return while penalizing the worst losses (5% tail). The result: a portfolio robust to bad scenarios, not just optimized for the average.

Shipped. Traveled. About to hack. Quorum is done (my benchmark proved me wrong), Valencia to meet Linear's CTO, and heading to Barcelona this week for Project Europe hackathon. Details: alexlopezg.substack.com/p/two-weeks-no…

Most people think AI is a tool you use. They're wrong. AI is a way of operating you adopt. The shift that matters: - Intuitive → Explicit - Stories → Structures - "Feels right" → Measurable You can't design systems for agents until you think like one.

I've been studying how the best AI companies actually grow. The pattern isn't what most people think. Carles Reina (GTM at ElevenLabs) showed me a different framework: Global infrastructure → Local wedge Here's how it works:open.substack.com/pub/alexlopezg…
