What's next — scenarios
The Embodied AI Boom (Upside) (35%)
NdotLight secures enterprise contracts with major robotics firms, validating the simulation-as-a-service model.
- Announcement of NdotLight partnership with a global automotive or humanoid robotics leader
- Successful Series B funding round led by non-Korean VC
The Infrastructure Standard (Base Case) (50%)
NdotLight becomes a core component of NAVER's AI stack, providing steady, predictable B2B revenue.
- Integration of NdotLight simulation tools into NAVER's proprietary foundation models
- Consistent headcount growth in NdotLight's engineering department
Simulation Bottleneck (Downside) (15%)
Capital expenditure increases without proportional gains in physical AI performance, leading to D2SF reassessing follow-on commitment.
- Delay in NdotLight's product roadmap milestones
- Shift in NAVER's investment focus back toward Large Language Models (LLMs) over physical AI
