## Summary

Perplexity AI raised $500M at a $9B valuation in early 2025 and handles 100M+ monthly queries as the leading AI-native answer engine with cited sources.

## Company Overview

Perplexity AI has redefined web search by replacing ranked links with synthesized AI answers that cite their sources in real time. The platform processes queries using a combination of search index retrieval and LLM reasoning, delivering cited, conversational answers across research, shopping, coding, and news questions. Its Pro tier adds access to frontier models (GPT-4, Claude, Gemini) and unlimited search, driving rapid subscription revenue growth.

The company raised $500M at a $9B valuation in January 2025, led by SoftBank and IVP, as it expanded from consumer search into enterprise — launching Perplexity for Enterprise with SSO, data privacy controls, and API access. With 100M+ monthly queries and a rapidly growing user base drawn from knowledge workers and researchers, Perplexity has established itself as the primary AI search destination for users who need sourced, up-to-date information.

Perplexity competes directly with Google Search and Microsoft Bing AI, but differentiates through its answer-first, citation-forward interface and willingness to integrate any frontier model rather than building a proprietary LLM. The company is exploring advertising revenue models that maintain answer quality while monetizing its high-intent search traffic.
