01What it is

A sales layer that sits on top of an operator’s existing booking and payment tools and shows where deals are stalling.

02The problem

An enquiry arrives in one system, the available offices live in another, and the follow-up depends on whoever is at the front desk that afternoon. Deals die in the gaps.

03Why it matters

Operators already pay for booking software, a card processor and a door system. None of them own the sale. That was the missing piece, not more data.

04Rubin's role

I built the product and wrote the positioning it sells on.

05What was built

  • Catches every enquiry and puts follow-up in priority order
  • Matches a prospect to offices that are actually free
  • Drafts replies for an operator to review before they go out
  • A console showing stalled tours, unopened proposals and deals going cold
  • A free revenue-leak audit as the way in
