Agency Growth by the Numbers

Published research shows a crowded agency market where most owners say their growth engine is weak and few call their pipeline very healthy.

The Agency Playbook Journal, published by Tim Kilroy, collects the published statistics most useful to established agency owners, each with its original source. None of these figures are Tim Kilroy's own data.

How hard is it to grow a marketing agency right now?

Hard, by the published numbers. There are about 71,000 digital agencies in North America, and 93% of marketing service firms say their growth engine is not strong enough. Only 14% describe their pipeline as very healthy.

Common questions

How many digital agencies am I competing with?

The Promethean Research 2026 Digital Agency Industry Report counts about 71,000 digital agencies in North America, up 42% since 2024, and more than 200,000 worldwide. It also finds that 87% employ fewer than 50 people. That crowding is a strong reason to position clearly, because a generic agency is easy to confuse with thousands of others.

Why don’t referrals scale for an agency?

Referrals do not scale because you cannot decide to get more of them this month. They arrive because of past work, the quality of your service, and how you have treated your network. That makes them valuable but unpredictable. An agency that wants to grow on purpose needs a lead generation system it can turn up when revenue goals rise.

Does content marketing work for agencies?

Content marketing works for agencies when it is treated as a demand system rather than a publishing habit. Tim Kilroy’s content playbook cites Ehrenberg-Bass Institute and LinkedIn B2B Institute research that about 95% of B2B buyers are not in the market at any given time. Content keeps your name trusted during that window, so you are considered when the need arrives.

How long should a discovery call be?

Many B2B teams plan 30 to 45 minutes. Arcade’s 2026 B2B sales playbook describes a discovery call as a 30 to 45 minute structured conversation to qualify pain, budget, timeline, and stakeholders. For an agency, length matters less than the outcome: by the end, both sides should know enough to judge whether another call is worth the time.

Which financial numbers should an agency owner watch?

Tim Kilroy’s 2026 planning workshop names four: revenue against goal, expenses against budget, tax reserve, and real profit. Its bucket guidance puts owner salary at 10 to 15% of revenue, the tax reserve at 20%, and operating expenses at 50 to 60%. Treat these as planning guidance and confirm the specifics for your agency with your accountant.
