Practice by Numbers intentionally grows at a sustainable 35-40% while maintaining over 30% EBITDA. This "Rule of 70/80" (Growth % + Profit %) is achieved without venture capital, prioritizing long-term stability and customer satisfaction over hyper-growth.

Unlike the typical venture-backed narrative, Tim Mack's primary goal is not hyper-growth or a massive exit. Instead, he focuses on building a sustainable business that ensures long-term stability for his employees, prioritizing durability and mission over risky, high-growth strategies.

Chasing top-line revenue often leads to unsustainable growth and eventual collapse. Focusing on the bottom line (profitability) ensures the business is healthy, reduces founder stress, and provides the financial stability to create a better work environment and culture for employees.

With $60M in revenue and only 80 employees, Sense demonstrates world-class efficiency. CEO Alex Joukowski credits a culture where individuals grow exponentially with the business, avoiding common tech headcount bloat. His internal benchmark is an ambitious $1M in revenue per employee, driving a lean, high-performance organization.

Founder Sam Darawish argues that a healthy, moderate growth rate (25-30%) is often better than chasing venture-backed hyper-growth. He believes rapid growth can lead to taking on non-ICP customers, which pulls the product in multiple directions, wastes resources, and ultimately thins the team's focus.

The biggest risk for a founder isn't a quick failure, but a slow-growing company stuck at a few million in ARR. This 'zombie' state consumes years of your life without delivering on the venture-scale dream. To avoid this, anchor your startup in a future where the need for it is growing, not shrinking.

Brett Taylor argues that focusing solely on rapid growth can lead to 'fragile ARR.' The better metric is 'earned ARR,' which reflects sticky, high-quality revenue from satisfied customers and indicates a more durable business with a real moat.

Prioritize decisions that increase your business's sellable value (enterprise value) over just maximizing short-term profits. This involves strategically reinvesting profits to de-risk the business and build durable, long-term revenue streams, creating a more valuable asset.

The founder is comfortable with 35-40% growth because it allows the company to remain highly profitable (a "Rule of 70, 80 company"). They intentionally avoid "buying revenue" through aggressive spending, focusing instead on sustainable, inbound growth from high-quality customers to avoid breaking the business.
