AI-powered operating system for agencies
The whole agency, on one screen

AI-powered operating system for agencies
Thirty minutes, on your own numbers.
Proposals, delivery, client approvals, contractor work and the invoices at the end — run by one system, with AI doing the parts nobody wants to.
Watch it runClients, contractors, projects, and a twelve-week cash flow forecast — chart and week-by-week table. The real application, not a mock-up.
Not on the projects that went wrong — those are obvious. On the ones that felt fine. None of it shows up in a spreadsheet that only knows what you billed.
Not four tools that agree because somebody retyped the numbers.
A proposal drafted from the brief, sent for signature.
It becomes a contract. They sign from a link; you counter-sign.
Signs in with a link. Sees deliverables by milestone, approves with a reason, replies in a thread that emails you.
Milestone 2 — Build
Revenue minus the costs you remembered to enter is not margin, it is optimism.
An hour with no cost basis is reported as uncosted, not valued at zero — the difference between a number you can take to a pricing conversation and one that just looks reassuring.

12 hours recorded with no cost rate. Reported as uncosted, not as free.
Example figures.
Every hour carries a cost rate, not just a billing rate. An hour with no cost basis is reported as uncosted, never as zero.
Sign-in by link. Deliverables by milestone, approvals with a reason, a thread that emails them when you reply.
Tenant isolation in the database, enforced two-factor, and an audit log that takes no edits.
Not built, and said plainly: single sign-on, SOC 2 certification, accounting and chat integrations, portals on your own domain.
Every line names something the product does. No free tier — the demo is the introduction.
For a studio of one. Everything needed to run a single client engagement well.

Start on StarterMilestones, tasks, deliverables — and hours costed as they are logged.
Invoice from the milestone. They pay from a link. Margin updates.
Their own sign-in, their own hub. Assigned tasks, messages, files behind an NDA gate, and invoices they submit themselves.
Proposal to contract to invoice to paid, without retyping any of it.
Effective-dated rates at four levels, approved by a second person. Utilisation says "not measurable" rather than inventing forty hours.
Rules are data, not code. Dry-run before anything sends. The same fact twice still sends one email.
Scope from a brief, tasks from a milestone, a morning briefing. Grounded in your data, and it refuses to guess.
