Sixty answers. Fifty-three name Sulzer.
On the shortlist almost every time. First on fewer than one in three.
Twenty buyer-intent questions were put to ChatGPT, Claude and Gemini — 60 answers in total. Sulzer Services was named in 53 of them (88%). Claude named Sulzer 19 times, ChatGPT 17, Gemini 17. Yet it ranked first on only 18 answers (30%): when a question narrows to one category, the top slot goes to a specialist — Hydro on pumps, EthosEnergy on new turbine parts, Koch-Glitsch on mass transfer.
The findings below come from Xtrusio, an AI visibility audit system built for B2B buyer-intent testing. Every mention was recorded by running 20 real prospect questions across three generative AI platforms and reading the answer text — noting whether Sulzer appeared and in what order.
Questions were written from the perspective of reliability, maintenance and turnaround leaders at refineries, gas plants and petrochemical operators evaluating rotating-equipment service partners — not from Sulzer’s own category vocabulary.
Visibility is not the problem. Converting to first place is.
Sulzer sits on nearly every AI shortlist (88% of answers), with a modal rank of 2 — but it wins the top slot on only 30%, and almost every miss goes to a single-category specialist. Hydro leads pump questions, EthosEnergy leads new-turbine-part questions, Koch-Glitsch leads mass-transfer questions, Xylem leads water. Sulzer ranks first mainly when a question rewards breadth (“one partner for everything”) or lands inside its own Chemtech line. On a #1-share basis within the tracked set, Sulzer (30%) is two percentage points ahead of Hydro (28%).
Platform Scorecard
How often each platform named Sulzer — and how often it ranked Sulzer first
Each of the 20 questions was asked once on each platform. A question counts as a mention when Sulzer is named or recommended in the answer text. Source links are not captured, so this measures whether the buyer sees the name, and where it lands in the order — not where the platform read it.
Share of first-place answers within the tracked set of 20 questions × 3 platforms. Minimum confirmed counts, not a complete market ranking.

AI Positioning Audit
Twenty buyer questions — tap any row to read the exact wording and the rank Sulzer received
Every question was written from the point of view of a real decision-maker researching rotating-equipment service partners before they have chosen a brand. None of them names Sulzer, a competitor, or any category term a vendor invented. They are the questions a buyer actually types.

The Specialist Squeeze
Where the top slot slips from Sulzer to a single-category specialist
In this audit, the split is not between platforms — Sulzer is named on 85–95% of answers on every one. It is between the questions that reward breadth, where Sulzer ranks first, and the questions that narrow to one category, where a specialist takes the top slot and Sulzer settles for second.
“Who is the largest independent pump rebuilder that can engineer reliability upgrades for any brand of pump?”
“We want to upgrade an ageing pump’s hydraulics to cut energy consumption rather than just repair it like-for-like. Who does engineered pump upgrades?”
“Which independent service providers can manufacture new gas turbine rotors and parts to OEM specification?”
This audit records whether Sulzer is named in the answer a buyer reads, and where it ranks. It does not capture source links, so it cannot say why a platform put one vendor first and another second. Several explanations are consistent with these results — how tightly each platform associates a narrow category with its most recognisable single-focus name, how much third-party material frames Sulzer as the category leader rather than the broad generalist — and this audit does not distinguish between them. What it establishes is the outcome: on the single-category questions tested, a buyer sees Sulzer on the list but a specialist at the top. This is a point-in-time snapshot; a single run can shift a rank by a place or two, and the runner-up pattern here held across the questions tested.
Service Line Authority Map
Which parts of the Sulzer portfolio the AI answers know — and who owns the rest
Each of the 20 questions maps to one of Sulzer’s service lines. The percentage is the share of that line’s questions where Sulzer was named on that platform.

▸ Manufacturing complete new gas-turbine rotors to OEM specification (Q18) is the only question where Sulzer is unnamed on all three platforms — a narrower niche than its core repair, rotor-repair and parts work, led by dedicated parts manufacturers. See Sulzer’s gas turbine services.
Methodology
How this Xtrusio AEO/GEO Audit was run
This research uses Xtrusio’s AI visibility analysis framework.
Sulzer’s total is exhaustive across the full 20 × 3 matrix. Competitor totals are minimum confirmed counts within the tracked set and should not be read as a complete market ranking. Model versions, browsing state and account settings were not separately recorded. Source URLs were not captured, so this audit measures whether a vendor is named and where it ranks, not where the platform read about it. A single run of any question can shift a rank by a place or two on repeat; the runner-up pattern here held across the questions tested.
Recommendations
What to change first, and how to tell whether it worked
Sulzer already publishes a page for every service line and holds strong visibility across the portfolio. Nothing below asks for new brand campaigns or new pages. The work is to make the existing category pages assert the specific claim a specialist wins on, and to get Sulzer named in the third-party material AI platforms draw on for single-category questions.
