History shows pioneers who fund massive infrastructure shifts, like railroads or the early internet, frequently lose their investment. The real profits are captured later by companies that build services on top of the now-established, de-risked platform.

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.

The fundamental goal is to become a "better competitive alternative" for a specific customer—being so superior that they bypass competitors to choose you. Achieving this state is the business equivalent of the house advantage in a casino (“the house vig”) and the only reliable way to build a lasting enterprise.

It's tempting to add adjacent revenue streams like training or job boards. However, these often represent entirely new business models requiring different organizational commitments, potentially distracting you from perfecting your primary revenue engine.

Venture investors aren't concerned when a portfolio company launches products that compete with their other investments. This is viewed as a positive signal of a massive winner—a company so dominant it expands into adjacent categories, which is the ultimate goal.

Businesses get into trouble by diversifying too early. Instead, focus on perfecting your primary revenue driver—the "spine" of the company. Once that foundation is solid and you're world-class at it, you have earned the right to expand.

Building a massive company requires a dual focus: investing in new innovations and constantly grinding to improve the core business. The latter is often unglamorous but is critical because the natural state of technology is decay, and the core business funds future bets.

Buyers pay a premium for predictable income, not just high revenue. Even non-SaaS businesses, like a home builder, can create valuable "durable revenue" by adding contract-based services like lawn care, significantly increasing enterprise value.

Airlines create immense value for society but capture almost none of it as profit, making them bad businesses. Google creates less total societal value but captures a huge portion. The ability to capture value is more critical than the volume of value created.
