A One-of-
“Encounter Database”

・Digitizing tens of millions of business cards per month, hundreds of millions per year.
・Analyzing how business connections come together, progress, and lead to further connections.
・Driving Sansan’s own product development and offering valuable data for global research.


What Is an Encounter Database?

When two people meet and
exchange business cards,
they’re exchanging data.
Millions of such exchanges are
happening constantly, all over
the world.
We digitize the business card
data from these exchanges.

This data represents
face-to-face encounters.

Deeply analyzing the data lets us visualize networks of
connections. In this way,
DSOC creates a database of
human connections and
networks: an Encounter


3 Key Features
of Data

  • #1


    Business cards contain names, companies, department names
    and roles, location and contact
    information, and other
    valuable details.
    No one puts incorrect
    information on their business
    card, and they update their
    card when they change
    positions or companies.
    This makes the data highly
    Subject this data to analysis and you can focus on certain attributes, see changes over time, and profile individuals and companies.

  • #2


    Business cards are exchanged
    in-person, face-to-face.
    They represent real-life
    Encounters upon encounters, when digitized and analyzed, reveal a comprehensive network of connections. These linkages are based on real-life interactions in a business context. Conventional social networks cannot show such insight.
    We can see connections
    between individuals,
    companies, and groups.
    We see the strengths and
    complexity of these
    connections in rich detail.

    DSOC’s proprietary system
    has digitized the information
    from hundreds of millions of
    business cards. It starts with
    the initial scan or snapshot.
    Data is then digitized by OCR
    in a couple of seconds. But it’s
    not done yet.
    A combination of machine
    learning and human
    verification then ensures near
    100% accuracy in the
