For service-based businesses, 80% gross margins should be the absolute minimum. This high margin is not just for profit; it is the essential fuel required to cover all other business costs like sales, marketing, and administration, making it a prerequisite for scaling.

Jeeves considers its in-house infrastructure layer—not its UI—to be its core product and moat. By building its own ledger and becoming a principal card issuer, it can abstract away partner complexity and offer a seamless, unified experience across 25 countries, a strategy they call "difficulty is very defensible."

Zillow moved from an ad marketplace for mortgages to originating loans itself. This captures margin from a high-cost part of the transaction, but more importantly, it allows Zillow to control and integrate the entire process, solving the consumer pain of juggling multiple vendors and disjointed communication.

If your business relies on third-party suppliers for deals (e.g., real estate wholesalers), the fastest way to grow is to acquire one. Your superior monetization model allows you to extract more value from their operation, giving you control over the entire supply chain.

A powerful software value-creation lever is "engineering out" partners. By acquiring or building technology that replaces a licensed third-party service, a company eliminates a variable cost. In SaaS, this cost reduction applies retroactively to the entire customer base, dramatically boosting gross margin.

By building its own financial stack "straight to the metal" on MasterCard, bypassing third-party issuers, Brex gained a crucial advantage. This vertical integration provides the flexibility to launch in new countries with the "flip of a switch" and power complex embedded finance partnerships.

Jeeves uses AI to achieve massive operational leverage, growing revenue 10x while reducing staff from 200 to 140. For example, a four-person underwriting team now handles billions in payment volume, a task that would have required 15 people just two years ago, leading to significant margin expansion.

When their card provider shut them down, Jeeves faced a 60-day gap with no product. To survive, they launched a credit-based payment product managed on a spreadsheet. This crisis-born MVP now accounts for 40% of the company's revenue.

For early-stage hard tech startups, the decision to vertically integrate isn't about margin improvement. It's a question of survival. You should only take on the immense risk and capital intensity of vertical integration if the company literally cannot exist without controlling that part of the supply chain or tech stack.
