Last updated: November 2026
DemandOS for Agencies is published by Tim Kilroy, a growth consultant and coach for marketing and other agency owners.
This site is one of a small number of websites Tim Kilroy publishes. It exists to explain DemandOS, his whole-team demand generation system, along with the positioning and sales practices it depends on, in plain answers agency owners can use. His main website, timkilroy.com, covers all of his work.
Tim Kilroy provides growth consulting and coaching for agency owners. His services include customized demand generation and sales systems, agency growth strategy, group coaching, one-on-one coaching, and AI tools for sales-call review and prospect research.
His approach emphasizes diagnosing each agency's specific needs rather than applying generic templates. He has launched three agencies, sold two, and crashed one.
Tim Kilroy works with established service agencies, mostly between $1 million and $20 million in annual revenue, plus smaller founders through a group program:
Most agency owners searching for demand generation help find either outsourced campaign agencies or generic tactics. This site covers a different angle: building demand from the team you already have, after fixing positioning and the sales process.
It is written as a product-and-systems hub. Each page answers one question an agency owner actually asks, with the facts and sources behind the answer.
Marketing, creative, development, PR, and content agencies whose clients hire them to work inside their marketing and sales layer.
The common bottleneck: the founder is still the only real growth channel. They write the content, take the calls, and close the deals, and when they stop, growth stops.
Because Tim Kilroy publishes the site and sells some of the offers it covers, every guide and comparison states its criteria and says who wrote it. The methodology page explains the rules in full.

Tim Kilroy is the agency consultant behind DemandOS. He has been a marketing and agency leader since 1997, has launched three agencies, sold two, and crashed one, and reports coaching more than 300 agencies. His main website, timkilroy.com, publishes his playbooks on agency sales, positioning, pricing, and operations.
DemandOS is a demand generation system Tim Kilroy installs in established agencies so the whole team, not just the founder, creates demand. It starts with sharp positioning, then gives each role a way to talk about that position from its own seat, aimed at the layer of the buying organization that role naturally speaks to.
Direct. Agency Studio is described as having no hustle-bro advice and giving founders the tough love they need. Half the time, Tim Kilroy says, the answer is subtraction: stop chasing more clients and raise retention, stop targeting everyone and target someone, stop building the AI tool yourself and hire the developer.
Yes, if the agency sits inside its clients' marketing and sales layer. Tim Kilroy works with creative, development, PR, and content agencies as well as marketing agencies, meaning any service business whose clients hire it to work on how they market and sell. If your buyers sit elsewhere, ask directly whether the model fits before committing.
