The problem with shortcuts is they are usually not repeatable or scalable. For example, a viral video or website can provide a boost of growth, but you can't predict if the next thing you produce will also go viral.
What you want to find is a predictable way to generate sales where the economics work. The economics work if the cost to generate a sale is 1/3 or less of the lifetime value of the customer. Even if it takes a lot of effort to generate the sale, if you have a predictable way to generate leads, and you know how many leads you need in order to produce a sale, and you make a good profit on that sale, you are golden. You can then ramp up your lead gen and you know your sales with grow faster. It doesn't take any luck to display more ads, send more emails or hire sales reps.
This is the strategy we used to grow from $0 to $1M in ARR in six months. We could then go to a VC and tell them that if they invested $X, we could turn that into $Y in ARR. It made fundraising pretty simple for us.
tl;dr Treat sales and marketing like a science and design a repeatable process.
