§ 01 · Studio · Retainers
The band between subscribing to a product and installing the full Engine. Five productized programs your team uses ongoing, at $5,000–$15,000/month. We operate the agents. Your team gets the output. No engagement commitment required.
Retainers run continuously, cancellable monthly. Many orgs start here and roll into a full engagement when the work scales.
§ 01
Retainers are the middle band. Below them: self-serve products. Above them: full engagements. The studio meets you at the cadence you need — and you can move between bands as the work grows.

§ 02
Start with one. Move between them. Roll into an engagement when the work justifies it. Or stay on retainer indefinitely — many do.

Each retainer has a fixed scope and a fixed monthly fee. You know what arrives, when, and at what cost. No SOW renegotiation. No hourly drift. No surprise invoices.
We operate the AI capability. You receive the output. The agents, the skills, the pipelines all run on Perpetual Core's infrastructure — the same eight-registry Engine the studio installs in full engagements. You don't inherit the substrate (that's the engagement); you inherit the output it produces.
Cancellable any month, 30 days' notice. Move up to a full engagement at any point — we discuss retainer credit toward engagement scope on a case-by-case basis, depending on the work already shipped.
Retainers are the studio at production cadence. Engagements are the studio at installation cadence. Same team. Same Engine. Different surface.
