These are its, not ours.

Six from one night's run for a WordPress product, with the hook each was built from. One scored 4/10 and is still here, because a page that only shows the good ones is lying about what a batch looks like.

Why you're here

Marketing is the job you never signed up for.

You started this to build the thing. Instead you're the media buyer, the copywriter, the editor and the person who forgot to post for eleven days.

You post when you remember.

Which is the weeks you aren't shipping, hiring or on support. Nothing compounds, so every month starts from zero.

Every creative needs a brief.

An hour of art direction you don't have, then a week of waiting, for one asset you'll test once and never learn from.

You can't tell what worked.

Three ads is not a test. With no volume there's no signal, so you end up guessing and calling it strategy.

An agency wants $4k and a quarter.

Retainer, kickoff call, strategy deck. Ninety days before anything is live, and they still ask you for the assets.

Meanwhile the ads beating you are the same twelve formats, running untouched for sixty days.

That's the whole game: find the formats that work in your niche, make a lot of them, kill the rest fast, and never stop. It isn't clever — it's just more work than one founder can do between everything else.

So don't do it. Hire the loop.

It doesn't answer prompts. It runs a loop.

Four moves, repeating. Every turn is informed by the last, so week six outperforms week one with nothing new from you.

01

Research the niche

Pulls the ads running against you, the hooks they lead with, and how long each has been live. The ones still spending are the ones that work.

02

Make the creative

Writes the angle, art-directs the frame, produces static and UGC-style video in your brand kit. Fifteen variants, not one.

03

Publish & spend

Builds the campaign, splits the budget, schedules the organic posts, ships. Your connected accounts, real placements.

04

Read & iterate

Kills losers by morning, clones the winning format into new angles, and tells you in one paragraph what it learned.

The core four

Paid

Meta, TikTok, YouTube

Creative testing at a cadence no freelancer will match: fifteen variants a night, budget shifted to whatever survives the morning, losers cut before they spend twice.

It does the labour, not the deciding. Set the leash per channel and change your mind any day.

Draft only

It researches and makes; nothing leaves the app until you say so. Good for week one.

One notification a day with the batch. Thumb up, thumb down, or edit the line. It posts what you cleared.

Autopilot

Inside a budget cap and your brand rules it ships alone and reports after. Most founders land here by month two.

Branding

It knows what you look like before it makes a single ad.

Start with a name and a sentence: it builds the wordmark, palette, type pairing, photography direction and a voice guide it then obeys in every caption. Already branded? Upload the kit and it adopts it.

brand kit — marks, palette, type

The obvious objection

“You want me to give an AI my ad account and my card.”

Correct, and you should be uneasy about it. So the guardrails aren't a promise in a support doc — they're these four things, and you can check every one from inside the app.

You set the monthly ceiling. It throttles itself days early to stay under, and tells you when it does. It has never got the authority to exceed it — not a rule it follows, a number it can't pass.

And on week one it can't publish anything at all. Draft-only is the default — it earns the leash by showing you work you'd have approved anyway.

See the three modes

Proof, such as it is

We have no customers yet. So it markets us.

Every ad that brought you to this page was made, published and iterated by the product, against our own budget. When we start spending, the numbers will be published here, including the bad weeks.

What a bad week sounds like

“Everything I made this week lost. Six angles, all under 0.7% click-through. I've paused them, put spend back on the format that works, and I'm testing a different hook tonight.”

A product that only shows its good weeks is a product you should assume has bad ones. When ours start, they go here too.

Pricing

Priced on what you spend.

Not seats, not credits. Testing $600 a month and running $30k aren't the same job — so they aren't the same price. Every band is the whole product.

Six from one run against a WordPress plugin product. It found the pain on Reddit, wrote the angle, art-directed the frame and scored its own work — the 4/10 is here too, because a page that only shows the good ones is lying about what a batch looks like.

The obvious objection

“You want me to give an AI my ad account and my card.”

Correct, and you should be uneasy about it. So the guardrails aren't a promise in a support doc — they're the four things below, and you can check every one of them from inside the app.

A hard cap, not a target

You set the monthly ceiling. It throttles itself days early to stay under, and tells you when it does. It has never got the authority to exceed it — not a rule it follows, a number it can't pass.

Brand rules it can't break

Words it will never use, claims it can't make, colours it won't leave. Written on day one, enforced on every asset before it's queued — not checked after it's live.

Everything is reversible

Every post can be pulled, every campaign paused, every decision undone from the notification that announced it. Revoke access on Meta's side and it stops the same minute — you don't have to ask us.

A log of every action

Timestamped: what it did, what it spent, and the reasoning it had at the time. Not a feed of activity — an auditable record you could hand to an accountant.

And on week one it can't publish anything at all. Draft-only is the default — it earns the leash by showing you work you'd have approved anyway.

See the three modes

Proof, such as it is

We have no customers yet. So it markets us.

When we start spending, every ad that brings someone here will be made, published and iterated by the product, against our own budget — and the numbers will be published here, including the bad weeks.

It's the only honest proof a pre-launch product can offer: not a testimonial, just our own account left open.

What a bad week sounds like

Everything I made this week lost. Six angles, all under 0.7% click-through. I've paused them, put spend back on the format that works, and I'm testing a different hook tonight.

A product that only shows its good weeks is a product you should assume has bad ones. When ours start, they go here too.

Once there are customers, this section becomes their numbers. Until then it's ours, and you can watch it work in real time.

Pricing

Priced on what you spend.

Not seats, not credits, not creatives. A founder testing $600 a month and a team running $30,000 aren't buying the same thing, so they don't pay the same. Every band is the whole product.
