What kind of work will you be doing? I'm in a similar situation (M&A side though), and I'm not sure what kind of value I could bring to a tech firm without the coding skills that are needed in a early stage startup.
Abstracted a little, capital markets start-ups. You could add value by hybridising Silicon Valley and New York.
Go any further, e.g. to a Pinterest, and I don't know. Maybe there is a business development role? I'd guess you'd be throwing away a lot of your existing value at that point.
Call people. Most are very willing to help.
