The tools answer one question. KalMatrix answers them all — every day, from your data.
Reads your Jira and GitHub, forecasts every sprint against your team’s own history, catches the board-vs-code gap, and hands you one decision a day. And it grades its own accuracy so you know whether to trust it.
