Sonar API and Enterprise -- How Perplexity Monetizes AI Search

Perplexity's business model goes far beyond consumer subscriptions. The Sonar API lets developers embed Perplexity's search capabilities into any application, while Enterprise plans ($40-$325/seat/month) target organizational adoption. This module covers the product tiers (Free, Pro at $20/month, Max at $200/month, Enterprise), the February 2026 advertising abandonment, revenue growth to $200M ARR, and the Deep Research feature. Candidates interviewing for product, growth, or business-facing roles especially need this context.
