This is an established business play for VC backed startups.
A SAAS is always two things, the product, and sales. You absolutely must have sales, because no matter how good the product is, you don't have a business if nobody buys it. So the product is optional.
The pitch is "We're the completely automated solution for X", but internally everything is done by hand. You then try to find some customers. If you don't get product-market fit, you shut down without having to spend anything on engineering. But if you do get product-market fit, great! Time to build out the actual automation. During the gap, it doesn't matter how bad your unit economics are, you can just use infinite VC money to hire thousands of people while promising the board you'll eventually lay them all off. You will experience hypergrowth during this period because you can underbid everyone else thanks to your endless spigot of money.
