Founders must consider their sales motion (e.g., PLG vs. enterprise sales-led) when designing the product. A product built for one motion won't sell effectively in another, potentially forcing a costly redesign. This concept extends "product-market fit" to "product-market-sales fit."

The slow growth of public SaaS isn't just an execution failure; it's a structural problem. We created so many VC-backed companies that markets became saturated, blocking adjacent expansion opportunities and creating a 'Total Addressable Market (TAM) trap'.

When moving beyond your initial niche, target adjacent verticals. For example, a company serving realtors should target mortgage brokers next, not an unrelated field like lawn maintenance. This strategy maximizes the transfer of product features, market knowledge, and potential word-of-mouth.

When launching into a competitive space, first build the table-stakes features to achieve parity. Then, develop at least one "binary differentiator"—a unique, compelling capability that solves a major pain point your competitors don't, making the choice clear for customers.

Don't force your sales team to learn and sell a completely new product. Instead, integrate the new capability into an existing, successful product, making it "first" or "default" for that channel. This reduces sales friction and complexity, leveraging established momentum for adoption.

A founder of an athletic underwear brand faces a classic strategic choice. One path is to focus narrowly to dominate a niche, like Spanx did. The other is to expand into adjacent products (like sports bras) to create a complete brand system. This highlights the core tension between operational focus and building a broader brand platform.

To grow an established product, introduce new formats (e.g., Instagram Stories, Google AI Mode) as separate but integrated experiences. This allows you to tap into new user behaviors without disrupting the expectations and mental models users have for the core product, avoiding confusion and accelerating adoption.

To scale effectively, resist complexity by using the 'Scaling Credo' framework. It mandates radical focus: pick one target market, one product, one customer acquisition channel, and one conversion tool. Stick to this combination for one full year before adding anything new.

Instead of diversifying randomly, a more effective strategy is to expand into adjacent verticals. Leverage your existing, happy clients for introductions into these parallel industries. This approach uses your established credibility and relationships as a bridge to new markets, lowering the barrier to entry.
