Most coffee is four months old.

“Why $19?”

What it learned. Close-up pour shots beat flat-lays by 2.4× on hook rate. Cloning the format into three new angles today.

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.

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.

Make the creative

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

Publish & spend

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

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.

Control

You stay the creative director.

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.

Approve first Default

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.

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

The questions you'd ask before handing over an ad account.

Short answers. The longer ones are in the product.

What is Cofounder?

Cofounder is an autonomous AI marketing agent for founders and small teams. It researches what is working in your niche, makes the creatives, publishes them to your own connected accounts, reads the numbers overnight, kills what lost and doubles down on what won — then tells you what it learned in a morning brief. It is built for the case where marketing is the job nobody at the company signed up for.

How is this different from ChatGPT or a prompt template?

A prompt gives you a draft when you ask for one. Cofounder owns the loop: it decides what to test without being asked, ships it to real placements on your own ad accounts, measures the result, and changes the next run based on what happened. The difference is not output quality, it is that nobody has to remember to run it.

Will it spend my money without asking?

Only if you tell it to, and never past the ceiling you set. You choose one of three autonomy modes per channel: Draft only, where nothing leaves the app until you say so; Approve first, the default, where one notification a day carries the batch for a thumb up or down; and Autopilot, where it ships inside your budget cap and brand rules and reports afterwards. The monthly ceiling is an authority limit it has no path to exceed, not a target it aims at — and it throttles itself days early to stay under.

What does Cofounder cost?

Pricing is banded on the ad spend it manages, billed monthly, on top of your own ad spend which you cap. Up to $1,000 a month in spend is $99. $1,000 to $5,000 is $249. $5,000 to $20,000 is $599. Past $20,000 a flat fee stops being honest, so it is priced against the accounts on a call, in writing. There is a 14-day free trial and you can cancel in one click.

Whose ad accounts does it use?

Yours. It connects to your own ad and social accounts and publishes to real placements under your brand, so the audience, the pixel data and the account history stay with you. Revoke access on the platform's side and it stops the same minute — you do not have to ask us.

What happens if it makes something off-brand?

Your brand kit is built on day one: words it will never use, claims it cannot make, colours it will not leave. Those rules are enforced on every asset before it is queued, not audited after it is live. Everything is also reversible — any post can be pulled, any campaign paused, and any decision undone from the notification that announced it.

What does it not do?

It does not decide your positioning, price your product, choose which market to enter, or negotiate partnerships. Those are judgement calls that need a person who carries the consequences. It does the labour, not the deciding.

Can I see what it did and why?

Every action is logged with a timestamp: what it did, what it spent, and the reasoning it had at the time. It is an auditable record rather than an activity feed — close enough to hand to an accountant.

Who is Cofounder for?

Founders and small teams who can build the product but have no paid-marketing function — solo founders, SaaS and ecommerce operators, B2B startups, agencies and local businesses. It is not built for funded growth teams who already employ marketers.

Is Cofounder available yet?

It is pre-launch and currently opening a founding cohort, whose rate stays locked to their band for as long as they stay. It has no customers, no published revenue figures and no third-party reviews yet.
