Sell the agency, not the founder.

Agencies are valued on the revenue that stays after the founder leaves. Black Key Holdings runs a marketing division, so we know exactly what a buyer is looking for: retainer revenue that renews, a client roster no single logo dominates, a delivery team that does not need the founder in the room, and margins that survive a change of control.
The practice
Black Key Advisory provides M&A advisory for digital marketing agencies, creative studios, media-buying and performance agencies, SEO and content shops, and web and software development agencies. We advise founders on valuation, readiness, confidential sale, and buyer selection among holding companies, private-equity-backed platforms, larger agencies and strategic acquirers.
Agency types we advise
Full-service and specialist agencies: performance media, SEO and content, creative and brand, web and app development, marketing technology consultancies, and vertical-specialist agencies serving one industry. Specialists with recurring retainers in a defined vertical typically attract the most focused buyer interest.
- Performance and media
- Paid media, programmatic, lifecycle. Valued on managed spend, margin on it, and retention.
- SEO and content
- Recurring retainers, long client tenure, process-driven delivery. Buyers test the process, not the founder.
- Creative and brand
- Project-heavy revenue that needs a retainer layer or a named-client roster to trade well.
- Development shops
- Web, app and platform builds, plus maintenance and hosting revenue that makes the base recurring.
- Vertical specialists
- Agencies serving one industry with proprietary playbooks and a defensible client base.
What moves an agency's value
Recurring retainer revenue as a share of the total, net revenue retention, client concentration, gross margin after delivery cost, the share of revenue that the founder personally sells or services, and the documentation of the delivery process. Agencies with retainer-heavy revenue, no client over ten percent, and a leadership team in place trade at a premium.
Raises the multiple
- Retainer revenue with multi-year client tenure
- No client above ten percent of revenue
- Account and delivery leadership that owns the relationships
- Documented playbooks and productized service lines
- Gross margin stable across the last three years
- Proprietary tooling or data that lowers delivery cost
- Growth from referrals and inbound, not founder selling
Lowers the multiple
- Founder is the rainmaker and the creative lead
- Project revenue that restarts at zero every quarter
- Two or three clients carrying half the revenue
- Contractor-heavy delivery with no continuity
- Margins that swing with a single client's spend
- Unclear IP ownership on work product or tools
Who buys agencies
Agency holding companies and private-equity-backed platforms consolidating capabilities or verticals, larger independent agencies adding a service line or a region, consultancies and technology firms buying a marketing capability, and, for smaller shops, individual operators and search funds. Each values a different thing and structures the deal differently.
- Holding companies and platforms
- Capability or vertical fit, retained leadership, earnouts on retained revenue.
- Larger agencies
- Geography, service-line expansion, cross-sell into an existing roster.
- Consultancies and tech firms
- A marketing capability to bolt onto an existing client relationship.
- Operators and search funds
- Cash-flowing shops with a manager in place, structured with seller notes.
What an agency buyer will check
Client contracts and their termination terms, revenue by client over three years, gross margin by service line, employee and contractor agreements, IP assignment on work product and tools, platform account ownership, revenue recognition, and how much of the pipeline depends on the founder.
- Contracts
- Retainer terms, notice periods, change-of-control clauses, exclusivity.
- Revenue by client
- Three years of client-level revenue and churn.
- Margin by service
- Which lines make money and which are subsidized.
- People
- Employment and contractor agreements, non-solicits, key-person dependence.
- IP and accounts
- Ownership of tools, templates, data, and client platform accounts.
- Pipeline
- Who sourced the last twenty wins, and whether they stay after close.
How agency deals are structured
Agency transactions commonly combine cash at close with an earnout tied to retained revenue or gross profit over one to three years, plus a transition role for the founder. Rollover equity is common with platform buyers. The earnout is where most of the negotiation lives, and its definitions matter more than its headline size.
We negotiate earnouts on metrics the seller can influence after close, with clear accounting definitions, protections against the buyer's own decisions reducing the number, and acceleration if the buyer sells again. A seller who does not read the earnout carefully is selling for the cash at close and hoping.
Why Black Key for an agency sale
We run a full-stack marketing engine inside Black Key Holdings. We know what buyers of agencies want because we have built what they want. Before a sale, our team can help productize service lines, tighten reporting and attribution, and move client relationships onto a team, so the agency that goes to market is worth more than the one that called us.
That preparation is operating work, and it is the difference between a founder-dependent shop and a transferable business.
Digital agencies · Questions
Questions owners ask
How are marketing agencies valued?
Primarily on a multiple of adjusted EBITDA or SDE, with the multiple moved by the share of recurring retainer revenue, client concentration, margin stability, and founder dependence. Retainer-heavy, diversified agencies with a leadership team trade at the top of the range for their size.
Do I have to stay after selling my agency?
Usually for a transition period, and often longer if there is an earnout. Buyers pay more for agencies where the founder is not the reason clients stay, so reducing your own role before the sale increases both price and freedom.
What is a typical earnout in an agency deal?
Deferred consideration paid over one to three years if the agency hits defined revenue or gross profit targets. The definitions, the seller's control over the outcome, and the protections against buyer interference matter more than the headline amount.
