You say this as if the goal of building a business (and measure of success) was to raise money? From what I can see, Front has 360+ employees and generates $64M in revenue, which works out to $177K revenue per headcount. Missive generates $2M with a headcount of 4, which comes out to $500k revenue per employee. Imo, generating almost 3x more revenue per headcount, and not having to deal with the headaches of managing a 360+ employee team (while maintaining complete ownership of your company) is the type of success that more founders should aspire to.
