Ask anyone who's bought custom software what happened to the date. The slipped deadline is so universal that the industry stopped apologizing for it. It's priced in. It's expected. It's the reason you keep a fake go-live date and a real one.
We run it differently, and the mechanics matter more than the promise.
All of the flexibility lives before the commitment. We scope with you. We build margin into the calendar on purpose. We will push back on a date we can't stand behind, and we'd rather lose the work than take a date on hope. What we will never do is commit and then negotiate.
After the commitment, there is no flexibility, because there doesn't need to be any. The prototype already exists before the date does. The risk that kills timelines on traditional projects, the wrong assumptions discovered in month four, is spent before we ever put a date in writing. A date moves for exactly one reason: you moved it.
That is the engagement model doing its job.
