## About the company

Vapi provides infrastructure for developers building voice AI applications. Its customers create agents and production call flows on top of APIs, making the product a usage-led platform rather than a static software seat purchase.

Developers can begin with an experiment, then expand through more agents, call volume, applications, and enterprise deployments. The commercial opportunity grows with production usage, while speech, model inference, telephony, and hosting costs scale directly with each call.

The model cohorts developers and accounts, converting active builders into paying usage. It forecasts call minutes, API pricing, enterprise commitments, expansion, churn, and usage-driven COGS, then layers developer relations, sales, engineering, gross margin, cash burn, and runway.

## 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

Vapi is a full-stack voice AI infrastructure layer that abstracts the complexity of building production-grade voice agents. Instead of months of specialized engineering, developers connect to Vapi and get:
- Enterprise telephony + WebRTC transport
- Conversational model orchestration (LLM routing)
- Deterministic call workflow engine
- Knowledge base & integration connectors
- Pre-integrated STT (Deepgram), LLM (Anthropic, OpenAI), TTS (ElevenLabs)

Value prop: "Or they could just use Vapi" - replaces a multi-vendor, multi-month build with a single API.

## Market

No explicit TAM/SAM/SOM figures given. Market context from deck:
- $400B global call center spend
- Billions of B2C phone calls made daily; ~8 per human
- 62% of SMB calls go unanswered
- 40% agent attrition in call centers
- Apple Intelligence + Gemini Live expected to onboard 4 billion people to generative voice
- Two addressable segments: Existing Call Volume (restaurants, insurance, banking, recruiting, auto, healthcare) and New Call Volume (hardware, therapy, roleplay training, language tutors, AI companions, children's toys)

No SAM or SOM quantified in deck.

## Revenue model

Not explicitly stated in deck. Based on product description and developer-platform archetype:
- Usage-based pricing on voice minutes consumed (standard for voice API platforms); rationale: Twilio/Deepgram/ElevenLabs all charge per-minute, and Vapi sits above all three.
- Possible tiered plans (free/starter for developer community, paid enterprise tiers with SLAs); rationale: deck highlights both startup ecosystem and enterprise customer closings.
- Channels: bottom-up developer-led (100% organic), plus top-down enterprise sales.

## Traction & metrics

- "Closing enterprise customers every week"
- "A startup ecosystem is sprouting up on our platform"
- "100% organic growth, thanks to our developer community"
- No revenue figures, ARR, MRR, customer counts, call volume, or retention rates disclosed in deck.

## Competition / moat

Not explicitly named. Implied competitive positioning:
- Replaces DIY multi-vendor voice stacks (Deepgram + LLM + ElevenLabs + telephony glued together)
- Moat narrative: scale (99.99% uptime for millions of calls), determinism engine, and developer community flywheel
- No direct competitors named in deck.

## Recommended financial model

- **Archetype + why:** Usage-based SaaS / developer API platform (voice-minutes consumed × per-minute rate). Closest comparable: Twilio. Revenue = [active customers] × [avg minutes/customer/month] × [blended per-minute price]. Enterprise tier adds committed-spend contracts on top. Two-segment model: SMB/startup (high volume, low ACV, self-serve) and Enterprise (lower volume, high ACV, sales-assisted).

- **Forecast horizon & granularity:** Monthly for Year 1–2; quarterly for Years 3–5. Five-year horizon appropriate for a growth-stage infrastructure company raising in Dec 2024.

- **Key drivers & assumptions:**

| Driver | Value |
| -- | -- |
| Blended per-minute API price | $0.05–0.10/min |
| Average call duration | 3–5 min |
| Enterprise customers (at model start) | "Closing every week" = ~4–8/month |
| Enterprise ACV | $50K–$250K |
| Gross margin | 40–60% |
| Organic CAC (dev) | ~$0 |
| Enterprise CAC | $10K–$30K |
| Net revenue retention | 110–130% |
| Call center market addressed | $400B spend |

- **Scenarios (Base / Bull / Bear - which variables flex):**
  - Bear: developer adoption slower than organic projections; enterprise sales cycle 6–9 months; per-minute price compresses to $0.03 as competition intensifies.
  - Base: steady developer community flywheel; 1–2 enterprise closes/week by mid-Year 2; price holds ~$0.05/min; GM expands to 55% as volume grows.
  - Bull: Apple/Google voice AI wave drives rapid developer adoption; 3+ enterprise closes/week; strategic wholesale deals with LLM providers compress COGS; GM reaches 65%+.

- **Required sheets / outputs:**
  1. Assumptions - all drivers above with scenario toggles
  2. Revenue model - cohort build: (a) self-serve developers: new devs/month × ramp curve × monthly minutes × price; (b) enterprise: new logos/month × ACV × expansion rate
  3. COGS - LLM/STT/TTS passthrough + hosting infra
  4. P&L - revenue, gross profit, S&M, R&D, G&A, EBITDA
  5. Headcount plan - tied to revenue bands (sales, eng, infra ops)
  6. Cash & runway - burn rate vs. raise proceeds
  7. KPI dashboard - minutes consumed, active customers, ARR, NRR, GM%
