i replaced a $6k/month agency with ai for $200. here's the exact 30-day migration.
the cost math is brutal once you see it — a full-service retainer is ~$72k a year, the ai stack that does the execution is ~$2.4k. here's how the swap actually goes, week by week, and where it bites.
most agency retainers are a bundle. you pay $6,000 a month for strategy, execution, account management, and reporting — and maybe 15% of that is the part you actually can't replace. the other 85% is execution: posting, drafting, scheduling, reporting, chasing. that part doesn't need a human anymore.
run the numbers and it's almost rude. a $6k/month agency is $72,000 a year. the ai stack that does the same execution is closer to $200/month — $2,400 a year. that's not a discount. it's a different category of business.
you're not firing your agency. you're unbundling it — keeping the 15% that's judgment, deleting the 85% that's labor.
the 30-day migration, for real
week 1 — map the bundle. list every single thing your agency does. not "social media" — the actual tasks: 12 posts, 4 emails, weekly report, monthly keyword pass. you can't replace what you haven't named.
week 2 — replace one channel, not all. pick the highest-volume, lowest-judgment channel (usually content scheduling or reporting). stand up the agents there. leave everything else with the agency. you're proving the swap, not betting the company.
week 3 — run them side by side. agent output and agency output, same week, same brief. compare on the only thing that matters: leads, sales, hours saved. not "does it feel as good" — does it move the number.
week 4 — cut what's proven, keep a human on retainer for the 15%. 5-10 hours a month of an actual specialist for the judgment calls. that's the hybrid everyone lands on, and it's right.
where it bites
ai is a production and analysis layer. it breaks the moment you expect it to make judgment calls with incomplete information — which campaign to kill, which client to fire, when the brand voice is off. keep a human on that. everything downstream of the decision, the agents handle.
i didn't theorize this. i run my agency this way. the migration is real, the math is real, and the part nobody tells you is that the hard step isn't the tech — it's being honest about how much of "agency work" was never strategy to begin with.
