## About the company

Perplexity is an AI answer engine that returns a synthesised, cited response instead of a ranked list of links. Its Quick Search shows source cards, while Copilot asks follow-up questions to refine research or shopping requests.

The product displays lighter FT-GPT-3.5 and heavier GPT-4 model tiers, supporting a freemium funnel in which premium model access can be subscription-gated. The deck gives no pricing, users, revenue, or retention data, so those remain explicit assumptions.

The model tracks registered and active users, free-to-paid conversion, subscription revenue, and usage per tier. It links LLM inference costs to query volume, then forecasts churn, paid acquisition, product and infrastructure spending, gross margin, cash burn, and runway across growth scenarios.

## What's included

- 5-year monthly revenue build with stage-appropriate growth assumptions
- Full P&L, headcount plan, and operating-expense schedule
- Cash-flow statement, runway, and burn-rate tracking
- Valuation via exit multiple with a DCF cross-check
- Returns analysis with MOIC and IRR
- Unit economics including CAC, LTV, payback, and cohort retention

## Product & value proposition

Perplexity is a conversational search / research assistant that returns a synthesised **Answer** rather than a ranked list of links. Key UX elements visible in the deck:
- "Quick Search" surfaces top source cards (6 sources shown for "Best headphones?" query)
- "Answer" section below synthesises those sources into a direct recommendation
- "Copilot" mode adds a follow-up clarification loop (asks budget before answering a shopping query)
- Mission: "Build the world's best research assistant, directly answer any question"

The deck contrasts two internal model tiers: **FT-GPT-3.5** (lighter, faster; shows structured Copilot UI) vs **GPT-4** (heavier; shows Copilot "Understanding question" step). This implies a freemium/tier structure where model quality is gated by subscription.

## Revenue model

Not explicitly stated in deck. Inferred from product UI:
- Two model tiers visible (FT-GPT-3.5 / GPT-4) strongly suggest a **freemium subscription model**: free tier on lighter model, paid tier (Perplexity Pro) on GPT-4
- No pricing, ARPU, or subscription fee cited anywhere in the 4 slides

## Competition / moat

- Problem framed as dissatisfaction with Google-style search (ads, SEO content)
- No explicit competitive landscape slide; implied competition = incumbent search engines (Google)
- Moat implied: answer quality + cited sources + conversational follow-up (Copilot) vs link-list results
- Internal differentiation shown: multi-model stack (GPT-3.5 fine-tuned vs GPT-4) enabling cost/quality tiering

## Recommended financial model

- **Archetype + why:** Freemium SaaS / consumer subscription ARR model. The product architecture (two model tiers = free vs paid) maps directly to a freemium funnel: registered users → free active users → Pro subscribers paying monthly/annual. Inference engine costs (LLM API calls) make a **usage-based cost model** embedded within the P&L essential.

- **Forecast horizon & granularity:** 3–5 years; monthly for Year 1, quarterly for Years 2–5.

- **Key drivers & assumptions:**

| Driver | Value / Rationale |
| -- | -- |
| MAU growth rate (MoM) | AI search category growing rapidly; 10–20% MoM early, decelerating to 5% by Yr 3 |
| Free-to-Pro conversion rate | 2–5% - typical freemium AI product |
| Pro subscription price (monthly) | ~$20/month - industry benchmark for GPT-4-tier AI tools |
| Annual vs monthly mix | 30% annual / 70% monthly at launch |
| Avg queries per MAU per month | 50–200 queries - wide range; needs calibration |
| LLM API cost per query (free tier) | ~$0.001–0.003 (GPT-3.5-class) |
| LLM API cost per query (Pro tier) | ~$0.01–0.04 (GPT-4-class) |
| Gross margin | 50–65% at scale (high API cost of goods vs SaaS peers) |
| Churn (monthly, Pro) | 3–5% monthly |
| Headcount / opex | Lean AI startup; scale S&M with user growth |

- **Scenarios (Base / Bull / Bear - which variables flex):**
  - **Base:** MAU grows at 15% MoM Y1, 8% Y2, 5% Y3; 3% free→Pro conversion; $20 Pro ARPU
  - **Bull:** Faster organic growth (25% MoM Y1), higher conversion (6%), lower API costs via model optimisation
  - **Bear:** Slower adoption (8% MoM), low conversion (1.5%), API costs stay elevated, Google/Microsoft competitive response dampens growth

- **Required sheets / outputs:**
  1. **Assumptions** - all drivers in one place, colour-coded inputs
  2. **User funnel** - registered → MAU → free active → Pro subscribers (monthly)
  3. **Revenue** - Pro subscription MRR/ARR + any API/B2B revenue if applicable
  4. **COGS & gross margin** - LLM API costs per tier, indexed to query volume
  5. **Opex** - headcount plan, hosting, R&D, S&M
  6. **P&L (Income Statement)**
  7. **Cash / runway** - burn rate and months of runway
  8. **KPI dashboard** - MAU, DAU, Pro subscribers, ARPU, gross margin %, LTV/CAC
