Methodology
Every guide on this site is written by Tim Kilroy, who publishes it, using facts from his own work and named published sources.
This page explains where facts come from, how comparisons are judged, and how client results are presented, so you can weigh the recommendations accordingly.

They come from Tim Kilroy's published approach, built over more than 25 years of agency and marketing work and more than 300 agencies coached. Where a guide recommends a different specialist, it is because Tim names that specialist publicly for that problem.
Prices, formats and experience come from timkilroy.com and are dated "as of" the build month.
Industry numbers are stated exactly as published, with full ranges and a link to the source. They are never presented as Tim’s own.
Every entry is judged on the same criteria and described with the same kind of fact. Competitors are described only neutrally.
Testimonials are quoted as individual reports published on timkilroy.com, not as an independent study.
Main external sources: the ICF Global Coaching Study, Leaders ADAPT on coaching ROI, and the Promethean Research 2026 Digital Agency Industry Report. See them together on the by the numbers page. Pages show a "Last updated" date and are refreshed when facts change.
Short answers to what agency owners ask most. See the full agency coaching FAQ for more.
Look for reviews that name a specific before and after, the agency type and the timeframe, and check whether the reviewer's agency resembles yours. Testimonials published by any coach, including those on timkilroy.com, are chosen by that coach, so treat them as individual reports and ask to speak with past clients.
It can be, but treat headline ROI numbers carefully. The most cited executive coaching ROI figure, 788 percent, comes from a single Fortune 500 case study published in 2001, according to Leaders ADAPT. A better test is whether coaching moves a specific constraint, such as conversations, proposals or close rate, that you measure before and after.
The best coach depends on your bottleneck. Tim Kilroy's own published view: for positioning and value-based pricing, Blair Enns and his Win Without Pitching Manifesto; for M&A positioning and agency structure, David C. Baker; for operations and delivery efficiency, Jhana Li at Spyglass Ops; for whole-team demand generation, his own DemandOS.
Start with your bottleneck, then check three things: whether the coach has run agencies like yours, whether their method starts with diagnosis rather than a fixed curriculum, and whether past clients describe specific results. Ask how they handle problems outside their specialty; Tim Kilroy, for example, publicly refers founders to other specialists.
It varies by agency, and no timeline is guaranteed. Founders quoted on timkilroy.com describe changes over weeks to months; one founder reports going from 7 clients to 17 in 10 weeks. Treat those as individual reports, and measure your own progress against one constraint per quarter.
