Tom Foremski of IMHO writes on how Ribbit (the self-styled "Silicon Valley's First Phone Company") was acquired by BT (British Telecom).
He wonders if start-ups are now designed from the ground with a disruptive marketing message in order to be bought out (aka, founders made wealthy) by incumbents:
Innovation has to be disruptive; therefore, as an incumbent you can survive anything that threatens you: you just need to identify disruptive technologies early, and buy them.
It's not hard to see entrenched CAD vendors using this strategy -- in the future, because they don't seem to be doing this now. With the possible exception of PTC buying CoCreate: was this in reaction to Siemens PLM Software working on synchtech?
