Documented cause
SynthBrain built a synthetic data generation platform for Korean AI teams building computer vision and NLP models, helping companies augment training datasets without collecting sensitive real-world data. The platform served 30+ enterprise clients in finance, manufacturing, and retail. The ChatGPT era fundamentally changed the landscape: foundation models pre-trained on massive real datasets reduced the need for proprietary training data among most enterprise use cases. Korean enterprises began using GPT-4 and open-source LLMs directly rather than building custom models that required synthetic training data. SynthBrain's pipeline dried up in 18 months.
Lesson
“AI infrastructure products that serve the "training data" layer are structurally vulnerable to foundation model shifts. Businesses should have monitored LLM progress and pivoted to a use-case layer defensible against fine-tuning approaches.”
