Theta Neurotech raises $1.75M pre-seed to monitor brain and predict epileptic seizures before they occur
Summary
Theta Neurotech announced raising $1.75 million in a pre-seed round in March 2026 to develop AI-powered EEG technology for epileptic seizure prediction. The company is targeting continuous ambulatory brain monitoring for seizure prediction — as opposed to detection after a seizure begins — which would enable patients to take preemptive action and avoid dangerous activities during high-risk periods. The pre-seed raise was highlighted in Neurotech Notables #51 alongside Audicin, Ruten, and other small-round neurotech companies demonstrating the breadth of early-stage investment across the sector.
Why it matters
Seizure prediction rather than detection is the clinically transformative advance that epilepsy patients have been waiting for — knowing a seizure is coming allows protective action that reactive detection cannot provide. Theta Neurotech's AI EEG approach builds on decades of academic seizure prediction research that has recently achieved meaningful accuracy improvements through deep learning on long-term ambulatory EEG datasets. The $1.75M pre-seed is the funding stage where the core algorithm needs to be validated before clinical trial funding.
