TLDRAravind Srinivas, CEO of Perplexity AI, discusses the journey and vision of his company in a fireside chat. Perplexity AI, established a year and a half ago, is an AI-powered search engine that focuses on transforming natural language queries into SQL. Initially, they built a prototype tool for analytics over Stripe data, which was well-received but lacked significant user traction. To overcome this, they scraped Twitter data to create a compelling demo called Bird-SQL, which attracted investors like Jeff Dean. As language models improved, Perplexity evolved its strategy to rely on less pre-processing and more inference-time processing. This shift has allowed them to offer a fast, conversational search experience that retains context for follow-up queries. Despite competition from tech giants, Perplexity has seen organic growth and aims to further refine its product and approach to search, positioning itself as a potential future alternative to traditional search engines.
