Cryptocurrency-enabled crime is a trillion-dollar global problem.

Cryptocurrency-enabled crime is a trillion-dollar global problem. It spans:

1. Money laundering ($2-5 Trillion)
2. Tax evasion ($50-200 Billion)
3. Fraud & scams ($15-30 Billion)
4. Drug trafficking ($20-50 Billion)
5. Crypto hacks & theft ($2-10 Billion)
6. Darknet markets ($2-5 Billion)

This is not surprising considering the massive size of the crypto market. In 2025, the volume of just two crypto stablecoins (USDT + USDC) was $33 Trillion. That's more than the annual GDP of the US and 8x India's GDP!

c4 AI

c4 AI finds the evidentiary needle in a haystack of data.

c4 AI analyses case files, screenshots, notes and multilingual text to uncover details investigators might otherwise miss.

In one case, c4 AI examined a dense block of Japanese text and detected a concealed 24-word crypto seed phrase. That discovery helped investigators dismantle a darknet operation.
