With Congress-Match the experience starts before the conference begins and continues during and after it ends.
With Congress-Match you can see who's attending, what is their line of business\interests and what are they looking for in the conference.
With a tinder like interface you can select which attendees you find interesting and check them. If they check you too, you both get each other contact details and now for business.
