BUSINESS PROBLEM

We believe global exposure is key to a well-rounded education

“Ensure inclusive and equitable quality education and promote lifelong learning for all”

Global traction and understanding underpins success in careers in today’s globally connected environment. To have global exposure from the vantage of a university education is invaluable for international networking and global vision; it also open doors to bigger opportunities.

When students approach their global exposure opportunities with an enthusiastic and open mind, the benefits are immense. Academically, gaining a first-hand, real-world perspective of issues learnt in the classroom serves to deepen students’ learning and knowledge application. More importantly, the journey builds independence, empathy, open-mindedness, not to mention soft-skills like communication and teamwork. These attributes not only build character and personal development, but also give students an edge when they are seeking employment and advancement in the competitive workplace.

The UN Sustainable Development Goals hold that quality education is a right for everyone

This opinion is echoed by SMU’s Graduate Learning Outcomes, under the Global Citizenship category

  1. Intercultural understanding and sensitivity
  2. Understanding of the Asian context
  3. Ethics and social responsibility
  4. Understanding of sustainability issues

Given the vast importance of Global Exposure, we believe that access to opportunities such as exchange should be as widely available as possible.

Therefore…

BUSINESS PROBLEM

Information regarding exchange is dispersed and volatile

Management

Strategy

Operations

Course mappings change often

What mapped one semester may not the next

SMU’s own course offerings also change

!

Information is hard to access

Information is passed from person to person

If you don’t know anyone, you’re out of luck

!

What students look for differs

Each student’s interests differ

What each student looks for differs too

INTRODUCTION SCENARIOS TECHNOLOGY CONCLUSION

A personalized, user-centric experience connecting students and universities aligned with their personal preferences is key

MONETIZATION

Our business model lends itself to monetization easily

Strategic options are available to universities looking to gather data and promote themselves

INTRODUCTION SCENARIOS TECHNOLOGY CONCLUSION

Students benefit

  • Access to unique and new experiences (trend of prioritizing authenticity)
  • Organic discovery of new universities

Universities benefit

  • New influx of interested and engaged students
  • Extended network opening up opportunities for more research and joint programs (competitive advantage!)
  • Better student-university matching
  • Get interested students of higher quality
  • Alcoholics rejoice!

Both students and universities get access to higher-quality opportunities with interested and engaged counterparts

VIABILITY

Our business model is attractive to both universities and students

Strategic options are available to universities looking to gather data and promote themselves

INTRODUCTION SCENARIOS TECHNOLOGY CONCLUSION

For students

92%

of Gen Z indicated being true or authentic to oneself is important

For universities

Access to a wide variety of new and authentic exchange experiences

Social search

is Gen Z’s first port of call when looking for information about products and services

Organic discovery of universities that appeal to students’ preferences

Student diversity

widens perspectives, challenges prejudices, and builds intercultural sensitivity

An influx of interested and engaged prospective international students

Global exposure

allows institutes of higher learning to stay at the forefront of technological development

Access to a high-quality pipeline of students who go the extra mile

Both students and universities have strong incentives to onboard to Uniexplorers, given the higher quality of opportunities available to both

More dump:

  • Strategic goal of global education for universities
  • Organic searching and matching

Monetization

  • Advertisement
  • Universities can be boosted
  • Summer schools?
