Have you got confirmation that as the firm grows so does your compensation? Also seeing they have raised 8 figures then, they should easily be able to pay you 150k + equity + bonuses, if they are not able to do this I would be concerned and would be concerned as they aren't able to compensate you properly.

Also note, that your investments won't immediately make any return so that is another thing to consider especially in terms of the fact that you will be on a lower salary initally and will have to "wait" to see the outcome of your investments in terms of making your % back.

Additionally, I don't think a shift in career would make your less marketable if anything it will increase it because, should the firm "fail" then you have learnt expertise to bring back into the marketplace as a consultant looking from more of a financial background to assess whether adding X feature is good in terms of value to the company or anyone - sure you can A/B test this stuff but you can get a quick understanding by having both sets of skills.
