Occupation	Co-founder and CTO of Entangl
Known for	Co-founding Entangl

Antanas Zilinskas is a Lithuanian-origin entrepreneur and engineer who co-founded and serves as chief technology officer (CTO) of Entangl, a Y Combinator (S24 batch) backed startup using artificial intelligence to detect and resolve issues in data center engineering and operations.

Early career

Zilinskas spent his early career in aerospace engineering, where he worked alongside co-founder Shapol M on a reusable rocket programme. He led development of the programme and managed four launch missions. That background in high-stakes engineering proved formative. Precision design, cross-team coordination, and operational safety are disciplines that don't forgive errors lightly, and the lessons Zilinskas drew from that environment directly shaped how he and Shapol M would later approach automated error detection for complex engineering systems. The specific organisation and programme Zilinskas worked with during this period have not been independently reported in available sources.

Entangl

In 2024, Zilinskas and Shapol M founded Entangl with the goal of automating the detection of design errors across engineering projects. Costly mistakes frequently slip through cross-team design reviews despite extensive preparation, and Entangl's platform was built to address that gap. The system scans knowledge bases, including GitHub, Google Drive, and OneDrive, to identify changes as they occur and assess their downstream effects across interconnected systems.

The company later pivoted toward the data center sector. Entangl's AI platform is designed to help data center operators catch mistakes before they trigger outages, keeping critical infrastructure efficient and operational. According to Entangl, the facilities it supports underpin a significant portion of global financial market infrastructure. The company also states that artificial general intelligence laboratories rely on its platform to maintain their data centers. Both claims come from Entangl's own materials and have not been independently verified by third parties.

Based in San Francisco, Entangl operates in the enterprise software and automation sectors. The company went through Y Combinator's S24 batch under group partner Tom Blomfield. Beyond Y Combinator, the company says it's backed by individuals from Nvidia, Cloudflare, AMD, and Hugging Face, though specific investor names and funding amounts have not been publicly disclosed in independent coverage.

As CTO, Zilinskas oversees development of the company's machine learning tools for error detection and prevention in complex engineering environments.
