Aleksas Petravicius

Aleksas Petravicius is a Lithuanian founder and technologist listed as co-founder and chief technology officer of Neurex, a Vilnius-based sleep-technology startup.¹² The company appears in Founders, Inc. wiki Canopy Spring 2026 company topics, which provides cohort context for his current venture.⁷ Public profile and event coverage connect his work at Neurex with earlier student-stage projects in neuro-adjacent and hardware-enabled product development.¹⁴

Neurex and technical focus

Petravicius's LinkedIn profile lists his current role as "Co-Founder & CTO" at Neurex with a March 2026 start date in Vilnius.¹ His profile headline describes work on brain-computer interfaces, EEG, embedded systems, and machine learning, and references Neurex directly.¹ The Neurex company page and website describe a sleep headband product focused on deep-sleep detection and stimulation, which aligns with the EEG-centered technical framing in his profile.²³

Before Neurex, his profile lists a chief executive role at BrAI between August 2025 and March 2026 with project language focused on neuro-adaptive work optimization using AI and EEG technologies.¹ The same profile includes ongoing education at ISM University of Management and Economics in entrepreneurship and innovation.¹ These details are currently profile-reported and not yet accompanied by separate long-form third-party reporting centered on BrAI itself.¹

Tailysis hackathon coverage

Independent event coverage by ISM and Delfi names Petravicius as part of the Tailysis team that placed second at a 2025 student vibecoding hackathon in Vilnius.⁴⁵⁶ The coverage describes Tailysis as a biometric dog-collar concept tracking heart rate, temperature, and movement to surface early stress or health signals.⁴⁶ ISM's English and Lithuanian reports include direct quotations attributed to Petravicius about rapid MVP building under deadline conditions and the impact on his entrepreneurial trajectory.⁴⁵

The same reports place the hackathon in a five-day format with 170 participants from multiple countries and universities, framing the project as part of a larger AI-assisted prototyping event rather than an isolated student demo.⁴⁶ In the available source set, this event is the strongest third-party documentation of Petravicius's pre-Neurex project work.⁴⁵
