A ~US$962M investment at risk every year
Indonesia invests heavily in sending its brightest students abroad — ~US$962M annually flows to UK universities through scholarships like LPDP, on the explicit expectation that scholars return and contribute to national development.
But a preventable transition gap — language, NHS, housing, visas, food, wellbeing — quietly erodes that investment. Students disengage, drop out or stay disconnected, producing 'brain waste' instead of returnable human capital.
A multi-level problem with no single owner
The gap sits across three failing layers at once: institutional (universities don't know who needs what), community (scholar associations are stretched thin), and individual (students don't know what they don't know until it's too late).
Any solution had to be culturally attuned, bilingual, 24/7, low-friction, and cheap enough to scale to thousands of students without grant-funded gatekeeping.
WhatsApp-native, bilingual, multi-level
We chose to meet students where they already are. 90.9% of Indonesians use WhatsApp daily. No app installs, no onboarding tax, no learning curve.
Phase 1
Pilot — 2–3 UK campuses
Co-creation with PPI UK, university international offices, LPDP
Step-by-step guidance across academics, NHS, housing, visas, food and wellbeing — in Bahasa Indonesia and English.
Phase 2
UK-wide rollout
Layered partnerships with host universities
Verified-info loop with continuous learning from every interaction; ethics & data-protection officers embedded.
Phase 3
Replication toolkit
Other nationalities · other host countries · labour migrants
TARA's architecture is transferable. The same multi-level model maps to Indonesian workers abroad and to migrants of other origins.
Decision-grade economics
Cost per interaction under US$0.50 vs. US$15–25 for equivalent human support. ~£5 per student reached protects ~US$96k of national investment per scholar-year.
- Selected as a Geneva Challenge 2025 Global Finalist (top from 100+ international teams).
- Aligned with SDGs 3 · 4 · 10 · 17 (health & wellbeing, quality education, reduced inequalities, partnerships).
- Built a 5-person team across Imperial, UCL and Hamburg with a co-creation governance stack.
“If you spend US$962M sending people somewhere, the rational thing to do is spend the next US$5 helping them land. TARA is that landing.”
