Business Models
How a company creates, delivers, and captures value. A weak business model is the #1 killer of startups — over 26% of failures cite it as a primary cause. Getting the model right is as important as building the product.
Common Startup Business Models
Subscription / SaaS
Recurring revenue for ongoing access to software or services.
- Strengths: Predictable revenue, high LTV, compounding growth
- Challenges: High churn sensitivity, long payback periods
- Pricing variants: Per-seat, tiered, usage-based, freemium
- Examples: Slack, Salesforce, Netflix
Marketplace
Platform connecting buyers and sellers, taking a cut of each transaction.
- Strengths: Network effects, asset-light, scales well
- Challenges: Chicken-and-egg problem, disintermediation risk
- Revenue: Transaction fees (typically 10-30%), listing fees, promoted placement
- Examples: Airbnb, Uber, Etsy, eBay
Transactional / E-commerce
Selling products directly to customers, either physical or digital.
- Strengths: Simple to understand, immediate revenue
- Challenges: Inventory risk, thin margins, high CAC
- Examples: Shopify merchants, Warby Parker, Casper
Freemium
Free base product with premium features for paying users.
- Strengths: Low friction acquisition, viral potential
- Challenges: Conversion rates typically 2-5%, free users cost money to serve
- Examples: Dropbox, Spotify, Zoom
Advertising
Free product monetized through ads.
- Strengths: Massive scale potential, zero friction
- Challenges: Requires enormous scale, low revenue per user, privacy concerns
- Examples: Google, Facebook, Twitter/X
Platform / API
Providing infrastructure or tools for other businesses to build on.
- Strengths: Deep lock-in, ecosystem value, compounding moats
- Challenges: High upfront investment, long sales cycles
- Examples: Stripe, Twilio, AWS
Choosing a Business Model
Key questions:
- How does the customer currently solve this problem? (Willingness to pay)
- What’s the natural transaction frequency? (One-time vs recurring)
- Where in the value chain do you sit? (End user vs business)
- What are the unit-economics? (CAC, LTV, payback period)
- Does the model support growth? (Network effects, viral, word-of-mouth)
The Business Model ≠ The Product
Many startups build great products but fail because the business model doesn’t work. The product solves a problem; the business model captures value from solving it. Both must be validated — often separately.
