How to sell a marketing agency?

Selling a marketing agency follows the same arc as any business sale, but the buyer scrutiny is specific. Start by cleaning up your books, separating owner add-backs to show true EBITDA or SDE, then establish a defensible valuation. From there you prepare marketing materials, approach qualified buyers, negotiate a letter of intent, work through due diligence, and close. A full process usually takes about 6-12 months.

Agencies typically trade around 4.0x-8.0x EBITDA, or roughly 2.0x-5.0x SDE for smaller, founder-run shops. What pushes you to the high end: recurring retainer revenue rather than project work, a clear vertical or service niche, gross margins that hold, and, critically, a delivery team and account relationships that do not depend on the founder.

Client concentration is the single biggest discount driver. If one or two clients are a large share of revenue, buyers will discount the price or structure more of it as an earnout. Founder dependence, where you are the rainmaker and the creative lead, is the second. Documented processes, a strong second-tier leadership bench, and contracts with notice periods all de-risk the deal.

Buyers range from individual operators (about 2x-3x SDE) and search funds (3x-5x EBITDA) to private equity building agency platforms (4x-8x EBITDA) and strategic acquirers, larger agencies or holding companies, paying 5x-10x EBITDA for a capability or client roster they want. DealSeam is not a traditional business broker; it introduces agency owners to qualified buyers where there is a fit and is paid by the buyer, so sellers pay nothing.
