Interface preview, demo data
3 levels of ads growth. One at a time.
Every ad starts small. Only the proven ones earn a bigger budget.
Level 1
Baby Ads Split Test
Many small ads on small budgets. Creatives and audiences run side by side, and the data picks.
- Cuts losers once they've spent enough to judge
- Never decides on one day or one sale
pause $30 spent, 0 purchases
Level 2
Ad Graduation
Ads that hold CPA under your ceiling, with enough purchases, graduate out of the test.
- Checks CPA against your ceiling, days in a row
- Moves the winner to scale, after you approve
graduate CPA $14, 9 purchases
Level 3
Big Boy Scale Up
Graduates get real budget, raised in steps so delivery doesn't break.
- +20% per step, 48h cooldown between steps
- Rolls back if CPA slips past tolerance
scale $50 → $60 → $72 / day
Your ads run all night. You can't watch them.
Nagamon checks every ad set each morning against limits you set, then shows you exactly what it wants to do and why.
Find your CPA ceilingLosers run all night
An ad set that stops converting at 11pm keeps spending until you wake up and check.
Calls get made on feel
Pause or scale depends on the day you're having, not on a rule you wrote down.
Black boxes stay switched off
If a tool can't say why it touched your budget, you won't let it.
The limit itself is a guess
Without your real margins, every rule starts from the wrong CPA.
Three settings. Then it runs every morning.
Nagamon reads your Meta ad account, decides, and asks. It never deletes anything.
Set your numbers
Enter price and costs once per product, or let your store send real orders.
CPA ceiling: $22.87output
Set your limits
Daily budget caps, the biggest change per step, and the wait between changes. The kill switch stays with you.

Inside Nagamon. Small jobs, done the same way every day.
Cut loss
Pauses ad sets that pass your CPA ceiling, only after minimum spend, days and results.
Scale up
Raises budget on proven winners by 10 to 30% per step, one step per cooldown.
Auto rollback
If CPA slips past tolerance after a raise, it steps back on its own and logs why.
Audit log
Every action keeps its time, before and after, reason, data and approver. It can't be edited.
Daily report
Spend, purchases, CPA, ROAS and each action with its reason, by email or Telegram.
Pixel check
Confirms purchase events actually fire on your store, not just that the code is there. After launch.
Sell here, or where you already sell.
Ad decisions are only as good as the sales data behind them. Nagamon takes it from real orders, not from what you type in.

What CPA can you actually afford?
Most automation asks you for a CPA limit. This works it out from your real costs. Free, no signup, change any number.

Your limits. Not the model's.
The AI decides. Meta's API acts. You draw the lines both of them stay inside. Try the controls.
Automation mode
Nagamon drafts every action and waits. Nothing changes in Meta until you tap approve. This is where every account starts.
Kill switch
Automation is running
Every action is on the record
Time, ad set, before and after, the reason, the data behind it, and who approved it.
You set the caps
Daily and monthly budget ceilings, max change per step, cooldowns. The model works inside them.
One click to undo
Every pause and every budget change can be reversed from the log or the daily report.
Your access stays narrow
Encrypted tokens, minimum permissions, never written to logs. Ads are paused, never deleted.
Built to be trusted, not to look clever.
We skip the creative generator on purpose. Nagamon does one thing: budget decisions you can check.

Questions
Something else? Email us.
Will it change my ads without asking?
No. Every account starts in draft-approve mode, so nothing changes in Meta until you approve it. You can switch to auto later, and anything above your caps is still held for you.
Can it delete ads or campaigns?
No. Nagamon only pauses ad sets and adjusts budgets. Every change can be undone in one click.
What are the 3 levels of ads growth?
Baby Ads Split Test runs many small ads to find what works. Ad Graduation moves the proven ones out of the test. Big Boy Scale Up raises their budget in safe steps, with rollback.
Do I need my own online store?
No. You can sell from a Nagamon sales page with checkout. If you already use Shopify or WooCommerce, connect it instead and your orders flow in.
Which ad platforms does it work with?
Meta only for now, which covers Facebook and Instagram. We're getting the decisions right on one platform before adding Google or TikTok.
How does it handle currency and time zones?
It works in your ad account's currency and judges each day by your account's time zone, not our server's.
Is my Meta and store access safe?
Tokens are encrypted and never written to logs. We ask only for the permissions needed to read performance, read orders and manage ad set budgets.
When can I use it?
The CPA calculator works today, on this page. Automation opens to the waitlist in stages, starting with daily reports and the action log.
