Guests / narrator：于北川
Listen: 02:49–16:32. Yu recalls roughly forty million daily users when he joined, alongside anxiety about an entertainment product's ceiling. Familiar-person social features might create reasons to return even without wanting video, strengthening retention and broadening adoption.
Guests / narrator：谢君陶
Juntao joined OpusClip in 2023 and worked on payments, commercialization and growth products. Edited from a live presentation and questions, the episode covers acquisition, conversion, retention and insight. Its central idea is to make growth actions opportunities to understand users, beyond finding another traffic source.
Guests / narrator：虞快
Listen: 01:57–06:39 and 18:48–19:43. Yu lists doctors, lawyers, engineers specializing in particular languages, and people combining unusual disciplines or languages. A model company may know something is wrong without knowing how to evaluate medical or legal answers systematically. It needs judgment as well as labor.
Guests / narrator：Joe
The title connects three months in the United States, conviction and ten-million-dollar ARR. Joe is more specific: ACE Studio then earned about US$800,000 monthly, compared with a previous level above US$80,000. Growth was slow for five weeks before a change from week six. Multiplying US$800,000 by twelve gives about US$9.6 million, a monthly run rate rather than proof of full-year collections or revenue entirely meeting recurring-revenue definitions.
Guests / narrator：封诚
If a company connects AI throughout its processes and reports impressive coverage, has its business improved? Feng Cheng examines acquisition, conversion and delivery, then concentrates on leads already obtained: potential customers who receive slow responses or inadequate explanations.
Guests / narrator：赵充 / Joe / 胡修涵
Product–market fit, or PMF, means that a group of people repeatedly finds a product worth using or paying for. These three interviews show why no single number proves it for every business. An occasional office tool can first demonstrate that individual tasks merit payment. Professional software needs to participate in real delivery. A character entertainment product must explain why people return.
Guests / narrator：Jay 党嘉成
A prompt contains instructions, background and rules supplied to a model. Sharing one can resemble sharing a template, but a consumer may actually want a text adventure, a conversational character or a tool that repeatedly completes a task. FlowGPT’s changing description reflects a move from collecting instructions toward consuming those experiences directly on its platform.
Guests / narrator：张阳
How can a team outside its target market know whether it is building something people need? Zhang Yang begins by asking whether the team obtains real, firsthand information continuously and connects that understanding to product, payment and acquisition.
Guests / narrator：肖弘（Red）
Monica’s answer has three layers: appear where people work, connect consecutive steps, and use revenue and organizational capability to sustain improvement. A browser extension provides entry into the work itself. Buying an extension is a business tool for accelerating validation.
