I worked for a enterprise software company where we practiced incremental development. The quality of software was hardly stellar but they had a great sales team. By the time I left, they had 6000 customers, lot of them Fortune 500. It is also worth mentioning that they were completely bootstrapped until recently. Our customers were always ok with us informing them that features will be in x.0, as long as we delivered on them. Maybe, it was your market that prevented the lean startup methodology from being applied?
