That's why I recommended including how much money the company has raised. Companies with lots of money also have a lot of employees, hence skewing 'market rate' up to something significantly higher than you'll get from any < 10m raised company. It's like (obviously not as extreme, but I'm using hyperbole) comparing salaries for similar roles at non-profits vs. investment banks just because they're both in the same city.
