Roles to hire first as your agency passes 10 ad accounts
Guide · 2 min read · Updated 2026-10-06 · By the Cofoundr team
Hire for your biggest bottleneck, not for a job title. Measure where the hours go, then fill that constraint, whether it is media buying, client management, creative or reporting. Automate repeatable checks before adding people to do them.
Somewhere past ten ad accounts, the founder stops being able to see everything. The instinct is to hire another media buyer. Sometimes that is right. Often the real constraint is client communication, creative output or the hours lost to checking and reporting. Hiring the wrong role first is an expensive way to find out.
Find the bottleneck first
- Track hours per account for two weeks: routine checks, reporting, strategy and client contact.
- Note where quality slips: missed issues, late reports, slow creative, unhappy clients.
- Ask which tasks only you can do, and which of them should not need you.
Signals and the role they point to
- Accounts are underserved and issues are caught late: another performance marketer.
- Clients wait for answers or feel unheard: an account or client manager.
- Creative is the slowest step: a designer or video editor.
- Reporting and admin eat strategy time: reporting automation first, then an operations assistant.
- You are the single point of failure on everything: a senior hire who can own a group of accounts.
Automate before you hire
Checking accounts, finding wasted spend and building reports repeat on every account. In the scenario behind Cofoundr's time calculator they add up to about 94 hours a month for 4 accounts. Tools like Cofoundr take on that routine so a new hire spends their time on strategy and clients. See how to increase margins.
Write the role around outcomes
- Which accounts they own and what a good month looks like.
- What decisions they can make alone and what needs approval.
- How they will be onboarded and who reviews their work.
Protect against key-person risk
Each new hire adds a person who can leave. Keep a per-client record from day one so knowledge is not in one head. See knowledge transfer when a performance marketer leaves.
Do not forget to review
After three months, compare the hours and the quality with where you started. If the bottleneck has moved, the next hire should follow it.
Frequently asked questions
Should my first hire be a media buyer?
Only if account coverage is the bottleneck. If clients feel ignored or creative is the slowest step, another role may help more.
How many accounts should one person manage?
It depends on spend, complexity and how much routine is automated. Measure hours per account and use the capacity formula in the margins guide.
Is hiring the same as raising capacity?
Not always. Removing repeatable work can raise capacity as much as adding a person.
