Dimitris Fotis Sakellariou (Piramidal)

Overview

Dimitris Fotis Sakellariou, often referred to by his moniker "Piramidal," is a pioneering neuroengineer and AI scientist. He is best known as the founder and CEO of Piramidal, a cutting-edge neurotechnology startup based in San Francisco. Sakellariou's work primarily involves developing innovative AI models that interpret complex brainwave data, particularly for applications in intensive care units (ICUs). With over 15 years of experience, he has significantly contributed to the fields of computational neuroscience and neuroengineering, with a focus on EEG (electroencephalogram) analysis. Under his leadership, Piramidal has gained recognition for its ambitious goal of building the world's first large foundation model for the brain, which promises to revolutionize neurological diagnostics and patient care.

Recent Developments

August 2025: Piramidal, under Sakellariou's leadership, has partnered with the Cleveland Clinic to develop a large-scale AI model aimed at enhancing brain health monitoring in ICUs. This collaboration utilizes EEG data to interpret brain activity in real-time, enabling quicker medical interventions. The model has been refined using proprietary and public EEG datasets and targets applications in real-time patient monitoring, epilepsy, and sleep analysis.
August 2024: The startup secured $6 million in seed funding, supported by Y Combinator, Lionheart Ventures, and Adverb Ventures, to advance their AI-powered foundation model for brainwave analysis. This model aims to enhance the speed and accuracy of EEG interpretation, crucial for diagnosing neurological disorders.
2024: Sakellariou's AI model development at Piramidal attracted attention from major healthcare providers for its potential to manage and understand unexplored dimensions of brainwave data.
The announcement of a strategic collaboration with the Cleveland Clinic to co-develop and refine these models marks a significant step forward in the field of medical AI, aiming for a wider commercial rollout.
