Core Viewpoint - The primary focus for evaluating AI startups is user retention, which is crucial for their long-term viability and growth potential [5][6]. Group 1: Investment Criteria - User retention is emphasized as the key metric for assessing AI companies, as many lack sustained user engagement despite initial interest [5]. - The cost of re-engaging users in the mobile era is significantly high, making retention a critical factor for success [5]. Group 2: AI Application Opportunities - The most commercially viable AI applications are often not the most glamorous technologies, but rather those that address practical needs, such as meeting minutes [5]. - Examples of successful AI commercialization include Abridge and Plaud, with Plaud achieving a valuation of $1 billion and attracting interest from major companies [5]. Group 3: Competitive Landscape - In the US and China AI investment landscape, the fastest-growing companies are predominantly B2B in the US, while Chinese companies are mainly B2C [7]. - Chinese entrepreneurs are seen as well-positioned to innovate in user experience outside of AI, particularly in gaming, which has seen significant growth [7]. Group 4: Future Trends - The upcoming year is expected to witness a surge in AI applications, following the current focus on hardware and infrastructure [7]. - Predictions indicate that new major players in the AI space, akin to ByteDance and Kuaishou, are likely to emerge soon [7].
