[tragic]

I currently work in one week sprints and we do this. Not 100% of the time of course, and it's an internal facing team where the customers are two desks away. But I've also done it on other teams with proper paying customers.

The devil is in the definition. As an example, we have a tool that bootstraps a new Git repo and we're adding a feature that will include our company Rubocop config if it's a Ruby project. There is no reason on earth that this should take 3-5 developers a week to accomplish (never mind two). But it's a feature and it could be useful. And on top of all the other features, the tool is quite useful nowadays compared to the first extremely thin slice we did.

The trick is reducing what you're counting as a feature to the smallest thing that is actually worth bothering to use. It won't always fit into one or two weeks, especially if you're dependent on hardware manufacture, or beholden to the iOS store approval timetable or whatever. But for your line of business SAAS apps there's absolutely no technical reason why you can't do it; there may be human obstacles to doing so. (Hell, maybe we're all wrong and you shouldn't do it.)
