The AI cofounder that runs your marketing.

An AI cofounder is an agent that owns a function of your company end to end — not a chat window you have to drive. Ours owns marketing: it researches your niche, makes the creatives, ships them, reads the numbers, and changes its mind when the numbers say so.

Definition

What is an AI cofounder?

An AI cofounder is an autonomous system that owns a business function end to end. Three tests separate it from everything else calling itself AI: it decides without being asked, it acts on those decisions, and it is accountable for an outcome you can measure.

A tool waits for input. An assistant answers a question. A cofounder has a standing brief and comes back on Monday with what it did — and what it learned from the half that did not work.

The core four

The four jobs it owns

01 · Research

It reads what your customers actually complain about — in their words, with the receipts — and ranks the pain by how often it recurs. Not keyword volume: language.

02 · Creative

Statics and video in your brand kit, seeded by the pain that ranked highest. Every asset keeps the prompt that made it, so what wins can be repeated deliberately.

03 · Distribution

Into the accounts you already have, paused by default until you approve. It publishes on the cadence you set, in the weeks you disappear into product.

04 · Learning

Two days of signal, then it kills the bottom and clones the winners. What it learns seeds tomorrow's work, and every decision is on the record with the numbers behind it.

Onboarding

Your first thirty days

Week one it only drafts — nothing leaves the building while you decide whether to trust it. Week two it starts queueing for approval by 9am. By week four most founders have moved it to a daily ceiling and stopped reading every card.

Full walkthrough: your first thirty days.

Honesty

What it will not do

It will not invent a positioning you have not decided. It will not negotiate a partnership, price your product, or tell you which market to enter — those are judgement calls that need a person who carries the consequences.

It also will not co-brand its work. A founder's ad should look like theirs, not ours.

FAQ

Questions founders ask

What is an AI cofounder?

An AI cofounder is an agent that owns a function of your company end to end — not a chat window you have to drive. It decides, acts and reports back, rather than waiting to be prompted.

How is that different from an AI assistant?

An assistant answers when asked. A cofounder has a standing brief, a budget and a cadence, and comes back with what it did while you were doing something else.

Does it spend my money without asking?

Only if you let it. The default mode queues everything for approval, and a daily ceiling you set applies in every mode — it has no path to spend past it.

What happens if it gets something wrong?

Every kill, promote and hold is logged with the metrics that drove it, so a week of unattended running is a week you can audit line by line. You can move it back to draft-only any day.

Do I keep what it makes?

Yes. It is priced as software, cancellable monthly, and everything it produced stays yours.
