Research

Original studies on how AI answer engines represent B2B and medical device markets.

Buyers have started their sourcing research inside ChatGPT, Perplexity and AI Overviews. Those tools don't return ten links and leave the shortlisting to the buyer — they return a handful of company names and do the shortlisting themselves. We run structured audits of specific industry categories to find out who makes those lists and why, then publish the results, the method, and the limitations, so anyone can check the work or repeat it.

Who Do ChatGPT and Perplexity Recommend for Catheter Contract Manufacturing?

We asked ChatGPT and Perplexity the same five sourcing questions a medical device OEM would ask, then logged every company named and every source cited. Both engines cited manufacturers' own websites first — in every answer.

How we run these studies

One category at a time.

Broad cross-industry claims hide the variation that matters. Every study covers a single, specific buying category.

Identical questions across engines.

The same prompts, run cold, with no company name included — the way a buyer with no existing shortlist would ask.

Everything logged.

Every company named, the order they were named in, and every source the engine cited.

Method and limitations published.

The questions are printed verbatim in each study so anyone can replicate it and disagree with us.

Orthopedic implants. Sterile packaging. Laboratory instrumentation. If you'd like your category audited — or you want to know where your company currently appears — get in touch.
