When to Choose PLG Over SLG (and Vice Versa): The Founder's Decision Framework

The $10 million question: Should your startup bet on product-led growth or sales-led growth?

Most founders make this decision based on gut feelings, competitor analysis, or whatever growth strategy is trending on Twitter. That's exactly why 71% of startups waste 12+ months on the wrong growth approach before pivoting to what actually works.

This isn't about which strategy is "better"—it's about which strategy is better for YOUR specific situation. By the end of this framework, you'll have a clear, data-driven answer that could save your startup from months of wasted effort and burned cash.

The Decision Framework: 7 Critical Factors

This framework evaluates your startup across seven dimensions that determine growth strategy success. Each factor gets scored, and the final score reveals your optimal path forward.

Factor 1: Product Complexity and Time-to-Value

The Question: How quickly can a new user understand and get value from your product?

Choose PLG if:

• ✅ Users understand your value proposition in <60 seconds
• ✅ First success/aha moment happens within first session
• ✅ Core workflow requires <5 steps to complete
• ✅ Minimal setup or configuration required
• ✅ Self-explanatory UI that needs no training

Examples: Canva (design in minutes), Loom (record and share instantly), Grammarly (immediate writing feedback)

Choose SLG if:

• ❌ Product requires extensive onboarding or training
• ❌ Setup involves technical configuration or integrations
• ❌ Value emerges over weeks/months of usage
• ❌ Complex workflows with multiple user roles
• ❌ Requires behavior change or process overhaul

Examples: Salesforce (CRM customization), SAP (enterprise resource planning), Workday (HR transformation)

Scoring:

• PLG Score (3 points): Time-to-value under 5 minutes, self-explanatory product
• Neutral (2 points): Some complexity but achievable self-serve onboarding
• SLG Score (1 point): Requires explanation, training, or complex setup

Factor 2: Market Size and Customer Segmentation

The Question: Who are you selling to and how many of them exist?

Choose PLG if:

• ✅ Large addressable market (100K+ potential customers)
• ✅ Targeting SMBs, startups, or individual users
• ✅ Customers have similar needs and use cases
• ✅ Low-touch, high-volume business model

Market Reality: PLG works best with massive markets where you can't afford to sell to everyone individually.

• ❌ Targeting large enterprises or specific verticals
• ❌ Customers have unique, complex requirements
• ❌ High-touch, relationship-driven business model

Market Reality: SLG excels when you can afford to invest heavily in each customer relationship.

Scoring:

• PLG Score (3 points): 100K+ addressable market, SMB/consumer focus
• Neutral (2 points): 50K-100K market, mixed customer segments
• SLG Score (1 point): <50K market, enterprise/vertical focus

Factor 3: Price Point and Deal Economics

• ❌ Can justify CAC of $2K-15K per customer
• ❌ Low-volume, high-value economics preferred

Scoring:

• PLG Score (3 points): <$500/month pricing, high-volume model

The Question: How do your customers make purchasing decisions?

Choose PLG if:

• ✅ Individual users can make buying decisions

Common Decision-Making Mistakes

Mistake #1: Following Competitor Strategies Blindly

Wrong approach: "Competitor X uses PLG, so we should too" Right approach: "Our product, market, and team strengths determine our strategy"

Mistake #2: Choosing Based on Personal Preference

Wrong approach: "I don't like sales, so we'll do PLG" Right approach: "The data shows PLG/SLG fits our business model better"

Mistake #3: Thinking You Have to Choose Forever

Wrong approach: "We're a PLG company, we'll never do sales" Right approach: "We'll start with PLG and add sales when the data supports it"

Mistake #4: Ignoring Team Capabilities

Wrong approach: "PLG is the future, we'll figure out the product stuff" Right approach: "We have strong sales DNA, let's leverage that while building product capabilities"
