About Sansan

Sansan provides two key business card-based services: the eponymous ‘Sansan’, a contact management solution for corporations, and ‘Eight’, a professional networking solution for individuals. Sansan develops advanced technology to turn its users’ business cards into powerful, shareable, and actionable data.

B2B Contact Management “Sansan”

Launched in 2007, Sansan is a fully featured cloud-based contact management solution for corporations. Centered on business cards, and using a proprietary system of digitization harnessing the power of both AI and humans, it seamlessly organizes contacts into a secure online database, accessible at any time from either the Web App or Mobile App. The database is optimized and integrated with external information by an advanced AI system, and is fully shareable within organizations.

B2C Professional Social Networking “Eight”

Launched in 2012, Eight is a free-to-use multi-platform contact management and professional social networking tool for individuals.

Our response to COVID-19

Due to the COVID-19 situation, each employee can choose either to work from home or go to the office. Currently, it is possible for engineers to work completely remotely. After the situation subsides, we may require employees to regularly come to the office.

While we’ve supported relocation in the past, due to the COVID-19 situation we currently require you to already be a resident of Japan.
