Every industry code,
decoded and connected.
Find the right classification code, understand exactly what it means, and convert it across the systems that actually matter — ISIC and NACE, NAICS across North America, and the national standards of twenty-five more economies, from Belgium and Poland to Indonesia and Argentina. Every code and every crosswalk comes from the official statistical authority that publishes it.
One business. Twenty-nine different codes. Zero clarity.
Classification systems are fragmented across countries and overlap in confusing ways. The same soybean farm is labelled twenty-nine different ways — and each lives in its own opaque government tool.
