Group 3: AI's Role and Market Sentiment - The sell-off was triggered by Anthropic's announcement of an AI tool capable of automating various legal tasks, raising concerns about the future of SaaS [5][6]. - The market's reaction may be overly panicked, as SaaS still holds advantages in the SME market due to its low entry barriers [1][10]. - The SaaS market is expected to differentiate, with traditional SaaS potentially being replaced by AI-native solutions, which could expand the market size and cover more untapped SMEs [10][11].
