Level3AI, founded in July 2024 by Harry Yu and Zachary Wang, builds enterprise AI agents (branded 'Emily') that automate end-to-end customer engagement across voice, email, and chat. The platform is purpose-built for APAC complexity, handling interactions across 95+ languages and 16+ countries while integrating with both legacy and modern systems. Level3AI differentiates by guaranteeing business outcomes such as CSAT or conversion rates, backed by a full refund if agreed metrics are not met. Having profitably bootstrapped for 18 months, it powers 10M+ interactions for 1M+ end consumers across brands like GetGo, Carousell, Yuu Rewards, and Carsome. In January 2026 the company raised a $13M seed round led by Lightspeed, with BEENEXT, 500 Global, Sovereign's Capital, and Goodwater Capital participating, to fund R&D and APAC expansion.
