People assume that profitability is perfectly predictable in a spreadsheet - anyone who has run a business for any sustained amount of time knows how false that is. Sure, if you run a SaaS, the margins may be so large that you can hand-wave profitability and probably be ok.
But remember, your first super productive workers are not the ones who are are around 5 years later.
Your first smart and capable customers are not your average customer 5 years down the line.
If you are pursuing revenue growth at any cost, you could end up with a lot of revenue and no hope at being profitable.
Spreadsheets and fancy decks can be made to convincingly present whatever story you want to tell, regardless of reality - look at Uber/Lyft. When you look at how the public markets are punishing this now, it seems obvious, but when you’re smaller and gunning for your next round, it’s probably the furthest from your mind.
