[quantified]

I have worked for companies that chased breadth and companies that focused. The focused group contained the only real successes.

Breadth is a killer. It requires resources (eng, PM, executive) that are not available in young companies. Where it was pursued, the management imperative to build the broad set of capabilities without resourcing meant that almost everything sort of sucked. It was in one instance the result of a strong founder chasing every shiny buzzword even without a strong business justification.

Go with focus, unless you have proven-strong management and actual big-tech resourcing.
