We build the software your business runs on. Then AI agents do the admin work inside it.

Luiz was raised on Cape Cod, the peninsula east of Boston, Massachusetts. He graduated from high school there in 2018 and studied psychology at Cape Cod Community College.

He worked at Gade Group, a construction company, from 2016 to 2025. He started as a field worker, moved into the office as an administrator and estimator, became a division manager, took over office, project and business development management in 2022, and in 2023 became Head of Marketing, Sales and Business Development. By his own record, within two months of his taking over marketing the company's leads went from two or three a week to an average of 35 to 45 a month, and stayed there for the next two years.

At Margaritaville Resort Cape Cod in Hyannis, he led the grounds from design to completion. The architects handed Gade the blueprints; Luiz researched which trees would make the resort feel like Margaritaville and still belong on Cape Cod. That led him to cold-hardy windmill palms, which stay in the ground all year, and to seasonal palms and banana trees in containers that come inside for the winter. Gade's team then drew up the full landscape and hardscape design. By his account, he ran more than five landscape, masonry and hardscape crews on site: they removed the old landscape and parts of the previous hardscape and built nearly all of it new, and he led the project from start to completion in late August 2024 with the Gade team. By his account, the windmill palms along Route 132 were among the first planted in a Massachusetts commercial landscape to stay in the ground year-round.

"We lined Route 132 with these particular palms."

At a multi-million-dollar luxury home in South Dennis, he did more than the marketing. He helped shape the magazine features, worked with Coastal Lifestyle TV (the Cape Cod & The Islands Magazine program) to arrange its interview on the project, and appeared in it. He also worked on the build itself alongside his father, from the foundation to the finishing touches. By his account, he installed the acrylic window between the in-ground fire pit and the pool: a panel about eight inches thick and seven to eight feet long that holds back thousands of gallons of water, with imported materials and sealers that had to be measured, mixed and set in the right conditions and temperatures over more than two weeks. His résumé also lists a 2025 nomination for New England's 40 Under 40.

During his years at Gade he also started Viral Click Pro Digital Solutions, later Harmony Digital Solutions, a marketing agency that served the Gade Group companies and other home-service businesses. By his account, he ran it profitably for about a year and a half and grew it to nearly $6,000 a month in recurring revenue. In 2025 he closed the agency and left Gade to build a software and AI company full time: Harmony AI Technologies.

Along the way he taught himself to build software. He also taught himself the basics of quantum computing and began research with AI on writing code for quantum computers, alongside other research into how AI systems are designed and how large language models are built.

He started building his own agent harnesses early. The first was OverkillOS, which began as a set of markdown instruction files for his code editor, before he had a name for what he was making.

Today he builds complete apps, front to back, and the AI agent systems this company runs on. He also leads the research behind PSIM, our work on memory for personal AI. He speaks English and Portuguese, and some Spanish.
