Details

CallerID – advanced call protection

ID Caller is a mobile security system that protects users from phone fraud, spam, and stolen devices. The app identifies risky numbers in real time, warns the user about threats, and provides compensation if fraud or theft happens anyway.

This ensures safer communication and reduces the risk of data or financial loss.

Case Story

Vitaliy Yakushev
Vitaliy Yakushev
CEO & Founder at CallerID 

SelfStartGlobal was built to solve the complexity of university admissions. Traditional CRMs weren’t flexible enough for different processes, stages, and agent workflows. With Tetracode, we turned this into a customizable, automated platform that makes admissions structured and transparent for every institution.

Our goal was to manage the entire admissions journey in one place. Tetracode developed the core CRM system, screening tools, templates, and collaboration features. The result is a platform that streamlines operations and delivers a better experience for both administrators and applicants.

We built a smart call-screening platform that detects suspicious numbers in real time and alerts the user instantly. The system supports spam databases, automated warnings, fraud classification, and caller verification — protecting users before they answer the call.
