TODAY · THE KEPT FLAMEEvery era kept the same fire and rebuilt the room around it. In a practice, the fire is judgment, craft, and the relationships the work is built on. The room is everything that surrounds it — workflows, tools, and now AI. Hearth Advisory keeps the first while helping firms rebuild the second, so the work that matters survives every change of architecture.
