Keystone is a healthcare comparison platform that lets patients search for private GP appointments, MRI scans, physiotherapy, and other services by postcode, then compare nearby clinics side by side based on published prices, patient ratings, and typical availability. The platform publishes independent patient reviews that clinics cannot edit or delete, and it clearly labels sponsored listings so organic rankings remain unbiased. Users can request an appointment directly through the platform in under a minute, with the clinic confirming the exact time and price.

Problem
The NHS wait keeps moving, with official figures showing the typical patient waiting 12.5 weeks for treatment and the longest-waiting 8% over 38.5 weeks. Going private can mean being seen within days, but most clinics do not publish prices, forcing patients to ring reception for quotes that vary wildly between clinics on the same street. Existing directories list individual doctors rather than clinics, and some platforms let practitioners curate which reviews appear, making it hard to trust the information available.
Solution
Keystone provides a search platform where patients can type a service and postcode to see every nearby private clinic ranked in one list by price, distance, patient rating, and typical availability. The platform understands everyday phrasing, not just medical jargon, and shows published prices whether fixed, from, or a range, clearly stating when a clinic only quotes on enquiry. Patient reviews are published independently and labelled unverified until tied to a completed booking, and clinics cannot edit, gate, or delete them. Users can request an appointment in under a minute, with the clinic confirming the exact time and price, and sponsored listings are always clearly labelled so paid placement never changes organic ranking.
