Fifteen years building AI products at the frontier: Meta’s first AI assistant for advertisers, the first multimodal Alexa at Amazon, the first conversational AI for classrooms at Merlyn Mind, where he was Head of Product.

Cristian Penarrieta

Founder

Twenty years shipping production systems, at Electronic Arts and then Gusto. He built a production platform for weekly mine data: deterministic ingestion, hybrid retrieval, and a Spanish-language assistant where the model picks the question and the server computes every number. Master’s in Computer Science, University of British Columbia.

Where the method comes from

The bottleneck moved. The work did not.

The knowledge acquisition bottleneck stalled expert systems in the 1980s: the rules lived in people and nobody could write them all down. Large language models removed the formalization step and moved the bottleneck to elicitation, a field with forty years of research behind it. That is the work: getting what your experts know out of their heads and into artifacts the company owns.
