  14. 14. Future prospects GoCredit system opens up a completely new potential domain For GoJek (PayTM Bank – GoJEK bank) Credit score as a service – Use the calculated credit score for enabling Various services Data collected by the system helps GoJek create detailed model Of every user 1. Use for targeted advertisements 2. Chatbot (Using contextual data collected , NLP algorithm created) 1. Automated helpdesk chatbot 2. Interactive chatbot for using GoJek services Copyright Skyline Labs 2016-17
  15. 15. Machine learning • Data unavailable for accurate prediction as of now • Sample data trained over linear regressions to calculate weightage of parameters • To train the backend – Limited release of GoCredit feature to collect data • Code for calculating weightage using ML is ready to demo Copyright Skyline Labs 2016-17
  16. 16. Privacy issues • Ask user permission to access data – If denied, GoCredits not available • Many applications (Including Google) access SMS data • Hash code the data captured - GoJek provides GoCredit without knowing who the user is. • Don’t send SMS data to server. Offline logic on smartphone will calculate the credit score and send to servers. Copyright Skyline Labs 2016-17
  17. 17. Money security • GoCredit system is created to be profitable – Model assures minimal risk • Maximum credit value allocated will not be high (50,000-60,000 Rupiah) • Credit is given only to the users with average monthly spending of a certain high amount (For example 1,00,000 rupiah) • Legally enforceable credit system – defaulting will lead to legal action • Credit allocation will be based assuming worst case scenarios – The data trained using ML will allocate 50,000 rupiah if credit worth calculated is of 1,00,000 rupiah. • Typical value for customer acquisition - ~30,000-40,000 rupiah. • Risk involved in GoCredit per user – equal to customer acquisition cost Copyright Skyline Labs 2016-17
