“Sentiment in the sector deteriorated after AI startup Anthropic unveiled an end-to-end workflow automation productivity tool, rekindling concerns that rapid advances in AI could disrupt traditional software business models and weigh on industry-wide profitability,” Ponmudi R, CEO of Enrich Money, an online trading and wealth tech firm, said.
