About this model
Stytch provides drop-in and API-driven passwordless authentication primitives including email magic links, SMS and WhatsApp passcodes, session management, OAuth, WebAuthn, embeddable links, and authenticator-app codes. Developers can use prebuilt UI flows or REST APIs and SDKs across web, iOS, Android, React Native, Node, Python, Ruby, and Go.
The research supports a consumption model that scales with authentication API calls and customer monthly active users, with enterprise contracts possible for larger deployments. It does not disclose pricing, customers, revenue, or usage. Its product value is reducing the engineering and abandonment costs associated with passwords and password resets.
The model should forecast developer accounts, production apps, authenticated MAUs, events, price, enterprise contracts, identity-infrastructure cost, expansion, churn, and NRR. Scenarios should separate self-serve API adoption from larger customers needing advanced authentication features, compliance, support, and account-management workflows.
A turnkey financial model
Live formulas, no hardcoded values
Outputs are driven by live formulas, so the workbook updates from its assumptions instead of relying on hardcoded results.
All assumptions in one tab
Inputs are clearly marked in the Assumptions tab and separated from calculations, making it clear what to change and what to leave intact.
Statements always balancing
For integrated-statement models, the balance sheet, cash flow, and supporting schedules tie through properly.
Distinct schedules for clarity
Debt, working capital, taxes, and cash flow can get messy quickly. We group calculations in clear schedules, not across disconnected tabs.
No hidden macros or external links
There are no unexplained external workbook links or macros to undermine auditability or portability.
Changes flow through the model
Update a key driver and see the impact carry through the forecast, financing, and return outputs. We never use hardcoded numbers in formulas.

How to build a detailed financial model for Stytch
A complete walkthrough of the business, drivers, and assumptions behind the downloadable Stytch model - distilled from its pitch deck and publicly available information.
Product & value proposition
Stytch provides a suite of drop-in and API-driven authentication primitives that replace passwords:
- Email magic links (desktop + mobile; removes "forgot password" flow)
- SMS one-time passcodes (OTP), WhatsApp passcodes, email passcodes
- Session management (single-point authorization)
- OAuth / OpenID logins
- WebAuthn (biometrics, hardware keys)
- Embeddable magic links (weave auth into any user interaction)
- Authenticator app passcodes
Integration options: prebuilt UI flows OR direct REST API; SDKs for Web (JS/React), iOS, Android, React Native; client libraries for Node, Python, Ruby, Go
Roadmap (2022): native biometrics, Login with Ethereum, push authentication, PIN creation
Traction & metrics
Industry stats cited (not Stytch-specific traction):
- Engineers spend 8+ weeks/year on auth maintenance on average
- 21% of users forget passwords within 2 weeks; 78% forget one in past 90 days
- 1/3 of online purchases abandoned due to forgotten passwords
- 75% of users who initiate password reset abandon the interaction
- IT teams spend 5 hours/week on password issues
- A password is reused 13x on average
- 92% of businesses believe passwordless is the future
Competition / moat
Not explicitly addressed. Positioning implied through product breadth (9 auth methods live + 4 on roadmap) and flexible integration model (prebuilt UI + raw API). Comparable vendors (Auth0, Okta, Firebase Auth) are not named. Moat framing is developer experience and passwordless-first architecture.

Recommended financial model
- Archetype + why: Usage-based / consumption SaaS ARR model. Stytch sells auth API calls and monthly active user (MAU) authentication volume to developer teams - identical billing mechanics to Auth0, Clerk, and WorkOS. Revenue scales with customer MAU growth, making a bottoms-up MAU-to-revenue driver tree the right structure. No evidence of seat-based or flat-fee pricing, so per-MAU tiers are the billing unit.
- Forecast horizon & granularity: 5-year annual model (Y1–Y5), with Y1 broken into monthly for cash management. Given early stage (Feb 2022, no traction shown), Y1–Y2 are build-out years and Y3–Y5 are growth curve years.
- Key drivers & assumptions:
*Customer acquisition*
- Number of customer accounts (companies) at period start
- New logo adds per month
- Churn rate (logo)
*Volume / consumption*
- Average MAUs authenticated per customer account
- MAU growth per customer per year
*Pricing*
- Revenue per MAU (blended)
- Free tier MAU threshold
*Unit economics*
- Gross margin
- SMS/OTP delivery cost per authentication event
- S&M as % of revenue
- R&D as % of revenue
- G&A
*Headcount*
- Engineering, sales, customer success hires by year
- Scenarios (Base / Bull / Bear - which variables flex):
- Bear: slower new logo adds, lower MAU growth per customer, higher SMS cost
- Base: PLG flywheel works, mid-market expansion, gross margin improves as SMS mix shifts to email/magic link
- Bull: enterprise deals close earlier, blended MAU price holds, MAU per customer ramps faster
- Required sheets / outputs:
- Assumptions - all drivers with toggle for scenario
- Customer model - logo count, MAU by cohort, blended revenue
- P&L - Revenue, COGS (infra + delivery), Gross Profit, OpEx (S&M / R&D / G&A), EBITDA
- Cash flow & runway - burn rate, cash balance, implied raise timing
- Summary / KPIs - ARR, NRR, CAC, LTV, LTV/CAC, gross margin, runway

Hey, I’m Alex and I created Finamodel.
Over my years in the finance industry I kept building the same models over and over again. Same structure, same assumptions, different logo. So I started building frameworks to turn them into clean, reusable templates.
Every model here is one I’d actually use for a client, and I personally vet each one before it goes up.
I’m not an expert in every industry, but I’ve built enough models to know what belongs in one. And when something is completely foreign to me, I reach out to my network for experts to work on our models with us.
Having a template library on hand cuts a first build from hours to minutes.
Need help finding your model? You’ll find me in the Finamodel app!
