Eesmyal Santos-Brault — AI builder and consultant. Twenty years at the intersection of technology, science, and social good. Ten organizations co-founded across companies, non-profits, and consortia. Two exits. Now running NodeBook and helping organizations deploy AI where it actually belongs.
Twenty years. Ten organizations co-founded — across for-profit companies, mission-driven non-profits, and industry consortia. One question still drives the work: where does AI actually belong in human operations — and how do we deploy it without hollowing people out?
I started in green building — co-founding Recollective, a values-driven consultancy that worked on 500+ green buildings in North America and was twice certified B-Corp in the global top 10%. From there: a coworking hub for change-makers (The HiVE), software for the built environment (OPEN Technologies), audio storytelling for green architecture (GBAT), and a design-driven creative collective that spread to seven other cities (Design Nerds).
The throughline shifted toward health and AI in 2018, when I co-founded Quantified Citizen — a mobile health-research platform applying AI, automation, and participatory science to behavioural studies. It produced one of the largest naturalistic datasets on psychedelic use globally and led to peer-reviewed papers in Nature's Scientific Reports and Psychopharmacology.
Today I run NodeBook, my AI & automation consulting practice. I work with organizations deploying AI in the real world: voice agents for healthcare contact centers, knowledge graphs and conversational interfaces, agentic workflows, and the messier strategy work of figuring out where AI actually belongs in an operation — and where it doesn't. Clients range from public-health institutions to small businesses in my own community.
Underneath the client work, NodeBook is also the home of a long-term R&D thread: a temporal multimodal knowledge graph platform for personal and collective cognition. How do we extend human thinking with AI in ways that make us sharper rather than more dependent?

I take a small number of consulting engagements at a time. Public-health and research institutions, founders building real products, and local businesses all welcome.
