No audit
Client results are self-reported
Testimonial figures, such as client counts and MRR changes, are what clients reported to Tim Kilroy. They were not independently verified, and they show selected outcomes rather than typical ones.
Methodology
How this site explains and recommends
The Agency Demand System uses only facts Tim Kilroy has published, plus named third-party research, and labels which is which.
Every price, client result, and framework on this site comes from timkilroy.com. Every market statistic is attributed to the report that published it. Where we compare options, each one is judged on the same stated criteria, and the site never presents itself as independent.

How are recommendations on this site formed?
Recommendations follow the bottleneck, not the brand. The coach guide matches each option to the specific problem it addresses, using the recommendations Tim Kilroy makes publicly. Tim Kilroy is listed first because he publishes the site and DemandOS is its subject, and that is stated on the page.
Source facts from the publisher
Prices, programs, frameworks, and testimonials come only from timkilroy.com.
Attribute every market number
Industry statistics are quoted as published, with the report named and linked, and never presented as Tim Kilroy’s own data.
Use the same criteria for every entry
Comparisons use matching columns, such as bottleneck, format, and price, for every option.
Say what we could not confirm
Where a fact is missing, the page says so rather than estimating.
Date the page
Each main page shows when it was last updated, and the date only changes when the content does.
What this site does not claim
No rating
No star rating is shown

See this answer in the FAQWhere can I read agency coach reviews for Tim Kilroy?
Client testimonials are published on the testimonials page at timkilroy.com, and our agency coach reviews page summarizes them. These are testimonials the business chose to publish, not an independent review site. Treat them as the client's own report and ask any coach for references you can call.
See this answer in the FAQWho should pick a different agency coach?
If your main bottleneck is delivery efficiency, Tim Kilroy himself points to Jhana Li at Spyglass Ops. For positioning and value-based pricing, he recommends Blair Enns's Win Without Pitching Manifesto. For M&A positioning and agency structure, he names David C. Baker. DemandOS is for the whole-team demand gap.

Start with two free checks. Run the 20-second positioning test with a client, a teammate, and a prospect, then run the 90-day funnel leak test. Together they show whether your bottleneck is message or pipeline. Tim Kilroy's free playbooks at timkilroy.com go deeper on each.
