Software is often called the "ultimate business model" because of its unique economics.
: Historically, software was "buy once, use forever" on floppy disks. Today, most businesses use Software-as-a-Service (SaaS) models, providing recurring revenue and constant updates.
: Unlike physical goods, once the first copy of software is written, the cost of selling the second copy is almost zero.
: One founder built a B2B product after seeing $15,000-per-seat software in their industry that was poorly made, realizing they could do it better on the side. 2. The Model: Why Software is Different
: Bill Gates and Paul Allen envisioned a "computer on every desk," realizing early that hardware is useless without the right software layers.
