Building AI agents, in public.

I'm Martín Alcalá Rubí. I've been building artificial intelligence companies since 2009. I co-founded Tryolabs and Zapia (+7M users) and I was its first CEO.

This is an open logbook of experiments, agents, open source projects and learnings, shared in real time.

What I'm working on

HarnessMachina

building

Your AI engine. On your hardware. On your terms.

Open-source AI orchestration platform for organizations with strict data-residency requirements. Deploy RAG, multi-model workflows and agentic systems 100% on-premise, even air-gapped.

    The China talk at the WTC was a hit talk

    Together with Juan Olloniego we shared at WTC Montevideo what we experienced at the Prosus Summit in Shenzhen. Turnout far exceeded our expectations: we expanded the venue twice and people still couldn't get in. Huge interest in AI, robotics and what's coming globally.

    Distributed inference on a DGX Spark cluster infra

    Exploring distributed inference on the NVIDIA stack: running open-weight models by splitting the load across several nodes of a local DGX Spark cluster. The goal is to serve larger models with low latency and no cloud dependency — all on-premise, on my own hardware. In parallel, testing the integration of those models with OpenClaw, Hermes and other local agents.

    I give a talk about AI in China, at the WTC talk

    Together with Juan Olloniego I share at WTC Montevideo what we saw in Shenzhen representing Zapia — meetings with Tencent, ByteDance, Galbot and SF Express — and what the scale and speed of that ecosystem means for those of us building technology from Latin America.
