商业模式拆解
买家：谁掌握预算？
未核实Developers and product/engineering teams at companies building voice agents and voice features (hypothesis from API/docs-led product).
触发点：什么让他们现在购买？
Need low-latency, natural multilingual voice (sub-50ms TTS) for real-time voice agents, translation and customer service.
工作流：什么输入变成什么输出？
Developer calls Gradium APIs for text-to-speech, speech-to-text, live voice-to-voice translation, voice cloning and voice design, or builds an agent via Gradbot, then pays by credits consumed.
经济账：省了什么，怎么收费？
Credit-based subscription: TTS 1 credit/character, STT 3 credits/second, S2S translation 30 credits/second; extra 100k credits cost $6.9 down to $3.8 by plan.
渠道：怎么接触到客户？
Self-serve signup with free plan and docs, plus "Talk to us" for Enterprise.
