Service businesses sell their expertise, but the first hour of every inquiry is spent on admin — reading, sorting, replying, guessing. Sieve takes that hour back. Inquiries land in one place, get scored against the rubric you set, and come back as a call-ready brief: what they want, whether they can afford it, how urgent it is, and what to ask next. You see the whole pipeline at a glance, work the ones that fit, and let the rest go politely. It runs the same way at 11pm as it does on a Tuesday morning, and it never forgets to follow up.
