The People in the Operating RoomNarrow moat

Intuitive Surgical (ISRG) — moat facet

4,837 people who are already in the room when the case starts — the part of the moat a rival has to displace first.

Intuitive employed approximately 17,021 full-time people at the end of 2025 — about 2,288 in research and development, 7,625 in manufacturing operations, 4,837 in commercial and service operations, and 2,271 in administration, across 29 countries, with turnover of 9.3%1.

More than a quarter of the company is in or near the operating room. That presence is what a rival has to displace before its robot is evaluated.

The commercial and service number is the one that matters competitively. The 10-K describes a clinical sales team that "works on site at hospitals, interacting with surgeons or physicians, operating room staff, and hospital administrators to develop and sustain successful robotic-assisted surgery or bronchoscopy programs", helping identify interested surgeons, providing clinical information and supporting new applications, and notes that this organisation "has grown with the expanded installed bases of da Vinci surgical systems and Ion endoluminal systems as well as the total number of procedures performed"2.

That is a field force embedded in the customer's workflow rather than calling on it. It is expensive — selling, general and administrative expenses were $2,385.0 million in 20253 — and it is the reason a hospital's relationship with Intuitive is continuous rather than transactional. A rival selling a competing system is not displacing a machine; it is displacing people who are already in the room when the case starts.

The manufacturing figure is the other half of the moat. Instruments are produced at Sunnyvale and Mexicali, endoscopes in Bulgaria and Germany, Ion in Blacksburg4 — Intuitive makes the consumables it sells, which is why the gross margin is 66% and why there is no third-party supply.

Selling, general and administrative expense as a share of revenue is the test: 23.7% in 2025, down from 25.6% in 20245. Falling while the field force grows means the installed base is absorbing the cost. Rising would mean it takes more selling to place each system.

Moat trajectory: Widening

4,837 sales and marketing employees of 17,021 total, and the two European distributor buy-backs convert third-party coverage into Intuitive's own people. The physical presence is expanding faster than the fleet.

Well over a quarter of the company is in or near the operating room. That presence is what a challenger has to displace before its robot is ever evaluated, and it is the cost that makes the field force a fixed charge against a variable market.

⚠ Threats to the moat
⚠ THREAT 01
The Field Force Is a Fixed Cost Against a Variable Market
Operating expense is guided to grow 11-13% against procedures at about 14.5%. Those numbers are too close together.
