My simple recommendation is, if $1.5m gives you 18 months of runway, and you need a $100k salary … raise $1.6m-$1.65m and pay yourself $100k.
There’s no right answer here. Two years without pay is at the point where it’s de-motivational, and risky, for the business. But you can’t put the company in danger by taking scare capital out. More on that here: In The Early Days, Don’t Forget To Pay Yourself, Too
Try to raise another $100k-$150k to pay yourself.
