Company snapshot

Perplexity is an AI answer engine: real-time web retrieval plus LLMs that return cited, conversational answers (web, mobile, and Comet browser) rather than a ranked link list alone (FACT — product / help center). Monetization is primarily freemium subscriptions (Standard free → Pro → Max) plus Enterprise per-seat tiers and a separate API Platform (Sonar, Agent, Search, Embeddings) billed pay-as-you-go; API is not included in consumer or Enterprise seats (FACT — help center Enterprise FAQ; docs pricing).

We do not invent ARR, valuation, MAU, or headcount as FACT metrics.

Revenue / pricing ladder (FACT — primary pages)

Consumer / education seats

  1. Standard (Free) — accurate answers with citations; limited daily usage framing on hub pricing; practically unlimited basic searches; very limited Pro Searches; basic AI models; limited file uploads; no advanced models / image generation / premium support (FACT — help center plan comparison; hub/pricing Free $0/month).
  2. Perplexity Pro — $20/month (annual options advertised on hub; help center notes annual billing nuances) — top AI models (user can select), expanded Computer access, Deep Research, Create files & apps, higher usage limits, file/image uploads, image generation, limited video, Comet Assistant; Pro includes Comet Plus membership path (FACT — hub/pricing; What is Perplexity Pro help article; Comet Plus blog).
  3. Education Pro — ~$10/month with SheerID student/educator verification — everything in Pro plus education tips/nudges (FACT — help center plan comparison; education pages).
  4. Perplexity Max — $200/month or $2,000/year (annual on web) — everything in Pro plus highest access to frontier models (OpenAI, Anthropic, etc.), highest Research/Create/Computer limits, Model Council, large Computer credit allotments (help/marketing cite e.g. 10,000 monthly credits + one-time bonus for eligible new accounts), priority new features; Max is consumer Free/Pro path — Enterprise users directed to Enterprise Max (FACT — Max help article last modified ~2026-09-14; hub/pricing).

Enterprise seats (FACT — Enterprise pricing FAQ, modified ~2026-09-04)

  1. Enterprise Pro — $40/seat/month or $400/seat/year — all Pro features + trust/privacy (data never used for training claim), advanced seat/admin management, shared Projects / File Connectors, higher usage vs consumer Pro, dedicated support. Education/nonprofit Enterprise Pro discount: $30/seat/mo or $300/seat/yr (FACT — help center).
  2. Enterprise Max — $325/seat/month or $3,250/seat/year — Enterprise Pro + highest Research/Create/Comet limits, large personal/project file caps (help cites up to 10,000 personal / 5,000 per project), video generation allotments (e.g. up to 15/month), collaboration + security packaging (FACT — Enterprise FAQ).
  3. API not included in Enterprise Pro/Max — purchase API credits / auto top-off separately; admins cannot manage other users’ API credits (FACT — Enterprise FAQ).

API Platform (FACT — docs.perplexity.ai/getting-started/pricing)

  1. Sonar API — tokens + request fees by search context size: e.g. Sonar $1/$1 per 1M in/out; Sonar Pro $3/$15; Sonar Reasoning Pro $2/$8; Sonar Deep Research adds citation/search/reasoning meters. Request fees per 1K: Sonar Low/Med/High $5 / $8 / $12; Sonar Pro / Reasoning Pro $6 / $10 / $14; Pro Search higher ($14 / $18 / $22 by context) (FACT — docs pricing).
  2. Search API — $5.00 per 1K successful requests (up to five queries per billed request) (FACT).
  3. Agent API tools — e.g. web_search $0.0025/invocation; fetch_url $0.0005; people_search / finance_search $0.005; sandbox $0.03/session (20-min billing window) + model tokens at provider rates with “no markup” claim for third-party models (FACT — docs).
  4. Embeddings — e.g. pplx-embed-v1-0.6b $0.004/1M tokens; 4b $0.03/1M; contextualized variants higher (FACT — docs).
  5. Purchase — credits / auto top-off; AWS Marketplace; Contact Sales for custom (FACT — docs).

Company blog: Agent API consolidates multi-provider + tools; Sonar remains available with a stated retirement toward Agent presets (2026-09-27 in company blog mapping) (FACT — hub blog “Agent API…”; treat retirement date as company-stated).

Comet / publishers (FACT — company hub blog)

  1. Comet — Perplexity’s Chromium AI browser; Comet Plus standalone $5/month; Pro and Max include Comet Plus. Company blog: publisher compensation model allocates subscription-related revenue with Perplexity retaining a portion for compute and distributing the rest to participating publishers based on human visits, search citations, and agent actions (FACT — introducing-comet-plus blog). Press reports an initial $42.5M publisher pool and 80%/20% split (SECONDARY — Axios/Digiday; not restated as audited FACT economics here).

Teaching arc (for canvas)

Free Standard (cited search) → Pro $20/mo → Max $200/mo → Enterprise Pro $40/seat → Enterprise Max $325/seat → API Platform PAYG (Sonar / Agent / Search / Embeddings; billed separately from seats).

Partners / ecosystem (FACT / company-stated)

Cost structure themes (INFERENCE only — no public P&L)

Inference/compute for multi-model answers + retrieval crawl/index, Computer/agent sandboxes, Comet browser distribution, publisher revenue share on Comet Plus path, and PLG + enterprise GTM. No opex lines disclosed as FACT.
