Known for	Co-founding Entangl

Antanas Zilinskas is a Lithuanian-origin entrepreneur and engineer who is the co-founder and chief technology officer (CTO) of Entangl, a Y Combinator (Summer 2024 batch) backed startup that uses artificial intelligence to detect and resolve issues in data center engineering and operations.

Career

Before founding Entangl, Zilinskas worked in aerospace engineering. Together with his co-founder Shapol M, he led a reusable rocket program and managed four launch missions. This experience in high-stakes engineering, where design precision and safety are critical, informed the pair's subsequent work in automated error detection for complex engineering systems.

Zilinskas and Shapol M co-founded Entangl in 2024. The company was initially conceived to automate the detection of design errors across engineering projects, addressing a longstanding problem in cross-team design reviews where costly mistakes often go undetected despite weeks of preparation. The platform scans knowledge bases—including repositories such as GitHub, Google Drive, and OneDrive—to detect changes as they occur and assess their potential impact across interconnected systems.

The company subsequently focused its product on the data center sector. Entangl's AI platform helps data center operators avoid mistakes that cause outages, ensuring efficiency and uptime for critical infrastructure. According to the company, trillions of dollars in global markets depend on the facilities it supports, and it claims that over 90% of the world's derivatives rely on the data centers it helps operate. The company states that AGI laboratories use Entangl to keep their data centers online.

Entangl is based in San Francisco and operates in the enterprise software and automation sectors. The company participated in Y Combinator's Summer 2024 batch under group partner Tom Blomfield. In addition to Y Combinator, Entangl states that it is backed by leaders from Nvidia, Cloudflare, AMD, and Hugging Face, among others.

Zilinskas serves as the company's CTO, overseeing the development of its machine learning tools for error detection and prevention in complex engineering environments.
