With Namsor, use personal names to determine new data points

Our mission is to help institutions and researchers make sense of Big Data, understand international capital flows and connect ideas and people.

Detail oriented

Namsor software currently supports several taxonomies for general use.

We also design specific taxonomies calibrated at a more granular level (regional dialects, ethnicity, casts or clanic systems) for the use of academic researchers and the specific needs of international organizations (migration studies, international aid, diaspora marketing and fundraising).

Global coverage

We constantly improve the accuracy of our tools, working with linguists, anthropologists and historians.

Namsor covers all languages, alphabets, countries and regions. Our offer accepts many alphabets: Cyrillic, Georgian, Latin, Arabic, Devanagari, Bengali, Greek, Armenian, Thai, Hebrew, Kannada, Gujarati, Tamil, Hangul, Telugu, Gurmukhi, Oriya, Han (Chinese traditional and simplified characters, Kanji), Hiragana, Myanmar, Katakana and Malayalam.

We value diversity

Namsor unlocks the value of diversity. We support public and private diaspora marketing and engagement programs, for human development and economic growth. We support @GenderGapGrader with our gender diversity analytics.

Combined with bio-cultural diversity metrics, Namsor helps reduce organizations's ethical and reputational risks. We can help measure gender, racial or ethnic biases in any funnel-based or selective process that uses machine learning or AI (such as: recruitment, credit allocation, KYC or anti-fraud).
