Marketing operations at large brands and agencies run on a growing stack of disconnected tools. Context degrades every time a brief changes hands, and one campaign still takes weeks.

"The problem was never the tools," says Marco Mendoza, CEO and founder of Hi Luca. "The problem is that nobody built the system that makes them work as one."

Hi Luca is a MarTech company building the Marketing Operating System for the AI era: one platform where large marketing operations load their brand, products, and buyer personas, launch campaigns, optimize them, and lower the cost of every decision.

Early experiments with large language model prompts were unreliable. "At the beginning we believed the problem was speed," Mendoza explains. "But it was not speed, it was context." Small, specialized agents sharing one brand memory solved it. Taking them to production at enterprise scale required security and governance, and Google Cloud with its Agent Development Kit made the path clear.

On Google Cloud, the application and core backend run on Compute Engine and Google Kubernetes Engine (GKE), with BigQuery managing campaign and performance data. The agent layer, built on Gemini and the Agent Development Kit, orchestrates specialized agents for strategy, copy, creative, and validation.

A marketing team loads its brand context, products, and buyer personas once. The platform proposes campaign ideas, maps audiences to real Google and Meta Ads segments, assembles validated creative variations, and delivers the campaign to Meta Ads Manager as a paused draft ready for approval.

A campaign that took three to four weeks and five to seven people now launches in under four hours with one orchestrator, at a fraction of the cost. Hi Luca's own development cycle is 70% supported by AI, used to write requirements documents.

"The benefits our clients experience are speed, diversity, and cost," Mendoza explains. "They launch more campaigns, with more creative diversity, without adding headcount for every new brand."
