卖什么
Custom models trained on your data
商业模式拆解
触发点：什么让他们现在购买？
Prompted third-party models do not learn from the company and are costly/slow; want faster, cheaper inference they own.
工作流：什么输入变成什么输出？
Discover (review system, define quality metrics), Refine (context/plumbing lift in days), Specialize (train model on customer data), Compound (production feedback loop); customer owns the weights.
经济账：省了什么，怎么收费？
未核实Likely custom services/engagement fees for training plus cheaper inference; no pricing published.
渠道：怎么接触到客户？
Engagement-led: Work with us form, reply from a Feyn engineer within two working days; open-source models and blog for inbound.
