Individual preview

Put Penumbra into your own work.

For founders, operators, researchers, and builders who want access to the live platform and a direct loop with the team as new surfaces harden around real work.

Personal access to the live platform
New product surfaces as they ship
MCP-oriented knowledge workflows
Direct feedback loop into the roadmap

Firm cohort

Turn one method slice into a working system.

For boutiques and service firms where expertise, review standards, and delivery method are the thing that must scale without getting diluted.

Hands-on mapping of the first method slice
Expert review standards made explicit
Workflow surface scoped around real delivery
Founding-cohort commercial terms

Platform preview

Build agents against a real domain model.

For builders who need the domain model to become tools, memory, APIs, extraction, provenance, and review instead of another prompt layer.

Shape-driven domain modeling
Generated tools, APIs, and memory surfaces
Builder sessions around one real agent workflow
Early access to platform primitives

INDIVIDUAL ACCESS

Live access to Penumbra, with a closer loop.

Individual access is the fastest way to become a Penumbra user today. You get the live system, new surfaces as they ship, and a direct path to shape what becomes durable.

Larger team, firm, and builder deployments start with a working session so we can scope the right slice instead of pretending one flat plan fits every ontology.

HOW TO THINK ABOUT THE PREVIEW

The platform is live

You get working Penumbra surfaces today, with a closer loop as we harden the product around real workflows.

The domain context is the throughline

Interfaces will evolve without losing the work because the durable asset is the domain context behind them: objects, rules, standards, and provenance.

You help shape what hardens

The best preview users bring real work and sharp feedback. The goal is to identify the workflows that should become durable product surfaces.

TEAMS AND BUILDERS

Bring one real workflow. We will map the domain context behind it.

If you are evaluating Penumbra for a firm, platform, or enterprise workflow, the right next step is a working session, not a checkout form.
