To me, that's just reallocating resources. Any efficient system of capitalism will see that happening.
However IPO's with unreasonable valuations, and investments greater than what's needed is a pretty good sign of bubble. So i'll let linkedin, and facebook make me scared of a bubble. Not to mention the startup Color.
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.
Simplest answer: a tech deal team - Google, for example, has one internally.
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.
Big tech companies are buying up startups left and right. I am guessing they have some ex-M&A guys on staff (Note: The OP said that he was moving to tech, not necessarily a startup)
Forecasting, pricing and marketing analytics roles are all good transitions. Lots of excel still necessary - all you really need to learn is some SQL and maybe R/SAS.
