What the edition found
Size does not predict Reputation: Telstra Health is recommended more strongly than MedicalDirector
The sample separates Telstra Health from MedicalDirector on Reputation: Telstra Health 79 (range 73 to 85) against MedicalDirector 66 (range 60 to 72). The engines recommend it more strongly and name it less: Presence 24 against 37.
17 vendors the engines recommend but rarely name
17 of the 29 companies on the Leaderboard are Cult Favourites: named in under 15 percent of answers, and recommended for their benefits in the answers that reach them. Listed by composite, they include Coviu (48), Dedalus (48), and CareMonitor (41).
Further findings
Most of the Leaderboard needs to be found
Across the Leaderboard, the most room in the composite is Influence for eight; Presence for 21. The most room is the factor whose weight, times the points it sits short of a full score, is largest: the most composite still to gain.
Who could move by the next edition
On the Leaderboard, these companies' ranges reach a line, so the sample cannot place them firmly on their side of it. Reputation, against the line at 50: Healthengine (49 to 60), Nookal (48 to 56), and Splose (49 to 55). Presence, against the line at 15: Hotdoc (13 to 18), Zedmed (14 to 19), Oracle Health (14 to 19), Healthengine (10 to 15), and Zanda (10 to 15).
The engines agree on the most-named, and much less on everyone else
Consensus, compared as medians and not as a composite or a sector score: the two companies named by default, with Presence of 30 or more, have a median Consensus of 45.5. The other 27 companies on the Leaderboard have a median Consensus of 35.
Edition 1 read 830 answers from five AI engines (ChatGPT, Claude, Copilot, Gemini, and Perplexity) to 166 buyer questions. The engines named 28 companies. The 29 named most are on the Leaderboard, each scored on all five factors.
