Case File № 002 · The People

Three people.One obsession:what your clothes are made of.

CircFibre didn't come from a boardroom. It came from a builder, a brander and a researcher who kept asking “but what is it actually made of?” — until the question became a kit.

The Builder

Aidar Kalbaev

Aidar is the reason the SafeCheck Analyzer exists. He prototypes, breaks, rewires and re-tests hardware until a kid can run a real materials analysis with two buttons and zero risk. If something in the kit clicks, glows or seals shut — he obsessed over it first.

The Brander

Miron Krutiakov

Miron decided CircFibre wouldn't look like a toy — it would look like a case file. Every stamp, dossier and verdict sheet in the kit went through his desk. He's the voice that turns fiber science into a story kids beg to continue.

The Market Researcher

Tin Yan Alexandra

Alexandra has talked to dozens of parents, teachers and brutally honest kids. She finds out what families actually need — not what we assume — and keeps every decision honest, from the price to the packaging to the fourth mystery fabric.

Why we're on this case

It started with a label that lied.

A “100% cotton” tee that failed a lab test. A hoodie nobody could identify. One dinner-table question — “what is this shirt, actually?” — that wouldn't let three people sleep. CircFibre is the answer: real forensic technique, kid-sized, sealed and parent-approved.
