Was that a serious question? It doesn't matter if the product is terrible as long as they can make sales, revenue growth looks fine (unless you've built a $100M business in a year?), and they definitely do make money unless you're talking about profit, which in VC-funded companies is traded for faster growth and exit (like an IPO).
And its not growing rapdlit, and nor was its $100M in revenues built in a year.
I find it strange that you say they aren't growing fast enough but yet say they don't make any money when they are delaying profits precisely for growth. Have you ever actually started or run a business?
In this case, they are nowhere near profitability. They need the IPO to forestall bankruptcy, they are 12 months from running out of cash. Their profit margin is still a massively negative -35%. There are no signs this business can ever be significantly profitable.
And if that’s not good enough for you, companies I’ve founded have raised over $20M in VC funding, and one was 2 months from an IPO we pulled because though we were profitable our growth had fallen to “only” 20%. We sold that business for $100M to a public company.
