The challenge
- Customer support cost scaling linearly with rapid user growth, threatening unit economics
- Tier-1 support handling 70% of the same repeatable queries, indicating high automation potential
- Previous chatbot deployment attempts hitting under 50% resolution, damaging user trust
- Escalation quality inconsistent across chat, email and in-app channels
- Regional Tagalog-English code-mixing patterns breaking generic multilingual LLM performance
The Corpshore approach
- Built a dedicated AI training team labelling and refining Tagalog conversation data for model fine-tuning
- Deployed a human-in-the-loop workflow with a sub-60-second escalation SLA to protect user experience
- Established a RLHF loop feeding customer feedback signals directly back into weekly model training cycles
- Implemented language-aware routing distinguishing Tagalog code-mixing, pure English and Filipino formal register
- Instituted monthly model performance reviews with the client's machine learning engineering team
