Questions

Questions about Tim Kilroy

Who does Tim Kilroy work with?: Tim Kilroy works with agency owners at two levels. Agency Studio serves founders under $50K a month. SalesOS and DemandOS serve established marketing, creative, development, PR and content agencies between $1M and $20M a year whose growth still depends on the owner posting, pitching and chasing every lead.
Is this only for marketing agencies?: No. Tim Kilroy also works with creative, development, PR and content agencies. The common thread is that the agency sits inside its clients' marketing and sales layer. If your agency fits that description, the positioning, sales and demand work applies to you.
Can a solo consultant benefit from agency coaching?: Yes, if you are past the earliest stage. Tim Kilroy notes that staying a highly paid solo expert is a valid choice with zero shame. If you want to build a team instead, coaching helps you avoid hiring people who can only work at your direction, which creates overhead without freeing you.
Does Tim Kilroy offer a free first conversation?: Yes. timkilroy.com describes a free 30-minute call with no pitch: you explain what is going on, Tim helps diagnose the real problem, and you leave knowing what to fix first whether or not you work together. Details are on timkilroy.com.
Is there a free self-assessment for agency owners?: Yes. timkilroy.com offers the WTF Assessment, a 2-minute diagnostic that shows where your agency is stuck and which tools to use first. It is a useful starting point before deciding between group coaching and a custom build.
Where can I read more of Tim Kilroy's thinking?: timkilroy.com publishes a blog and long-form playbooks on agency sales, discovery calls, positioning, cash flow, content marketing, account growth and follow-up, plus an Agency Research Hub that pairs industry reports with recommendations. All are free to read.
