# 15 minutes on your numbers with Deeplathe

> Fifteen minutes on your figures, not a slide deck. 30%+ on your profit comes from 1 of 2 places. Cost you stop spending, or revenue you aren't catching. Working out which one is open to you is the whole call. We'll go through: • One job in your week, and what it costs you to run it today • Which of the two it is for your business, and what an agent would actually do • What stays a person's job. There is always some, and we'll name it You leave with the arithmetic on your own numbers. No deck, no product menu, and no price before we both know the scope. If it isn't a fit, you'll hear that inside the fifteen minutes rather than in a follow-up sequence.
