Glasshouse enters closed alpha.
Glasshouse rehearses decisions against a simulated public. M&A, capex announcements, crisis responses, policy packages, activist plays, GTM repricings, anything where the cost of being wrong arrives faster than the time it takes to course-correct. Today it opens to a small cohort of design partners.
Creative Human AI · 1 May 2026
We have been running Glasshouse internally for eighteen months. Every public decision Creative Human itself has made: pricing, positioning, two leadership pivots, went through it before it went out the door. The platform is also the engine behind five public-record rehearsals already on file: Alphabet's Q4 capex framing, the UnitedHealth crisis response, Seven & i / Couche-Tard, Broadcom-VMware, and the German Kraftstoffmaßnahmenpaket. Each was constructed from material available before the event being rehearsed; each output is canonically pinned.
Closed alpha means: ten teams, hands-on co-design, named-partner support. The product is not waitlisted-and-forgotten: every alpha team gets a Creative Human engineer attached for the duration, and every run feeds the calibration loop that the next batch inherits.
What a rehearsal produces
One Glasshouse run is five stages. Each stage produces an artifact the next stage depends on, and each artifact is inspectable in the report.
- 01
Seeds
The decision document is parsed and typeset, the inputs the rest of the run will be evaluated against.
- 02
Graph
Stakeholders, their relationships, their leverage points. Built from the decision and the public record.
- 03
Personas
Each stakeholder is given an inspectable persona: disclosure, priors, constraints, vocabulary.
- 04
Simulation
Reactions are sampled across the cohort. Narrative-share bands form; minority views surface.
- 05
Report
Verdict, confidence band, pre- and post-decision matrix, pushback phrases, and the cohort coverage audit.
The report is the deliverable. Five surface tile types make it readable: here is what each one looks like, drawn from one of the rehearsals on file.
Decision Matrix
The first tile a decision-maker sees. Three to five framings, each scored against the simulated cohort, ranked by confidence band. The recommended option is not always the highest-confidence one: sometimes the answer is "the second-best option, because the highest-confidence one has a minority view we cannot afford to ignore."
How should the Q4 capex increase be framed?

Persona pull-quote
Each tile drills down. Tap a persona, get the verbatim: the line that persona would write, in their voice, about the option in front of them. Useful when the decision-maker needs to sense-check the simulation's read against a stakeholder they actually know.
If they cannot point to which workloads the spend underwrites by Q3, this is going to read as discretionary. The market has a tolerance for ambition; it does not have a tolerance for vagueness about return on it.
Confidence verdict
The headline output. One sentence, one confidence value, the exact sample size that produced it. Glasshouse refuses to round. If a verdict is HIGH at 0.71, it says 0.71.
"Reinvesting through the cycle" is the option the simulated cohort accepts as a credible framing of a costly decision.

Pushback phrases
The other half of the report. The simulated cohort produces real-language objections, the specific sentences the most adversarial readers would write. Useful for IR scripts, prep documents, and pre-mortems. If a phrase shows up here, it is going to show up on the call.

What closed alpha includes
- One named Creative Human engineer attached for the duration of the engagement, not a support queue.
- Up to twelve scenario rehearsals over the alpha window, with custom persona libraries per cohort.
- Methodology disclosure on every run: calibration history, persona provenance, confidence-band inputs, written for the security and audit reviews enterprise buyers actually run.
- Direct pipeline into the platform roadmap. What alpha partners need next is what we ship next.
Who it is for
Three kinds of decision-makers, mapped to the buyer archetypes Glasshouse was built around. CFOs and IR leads stress-testing announcement framings. CCOs and General Counsels war-gaming crisis response language. Hedge-fund event desks and policy ministries rehearsing decisions where the public record is the adversarial reader.
The methodology disclosure stays. The output is post-cutoff. The personas are inspectable. If you cannot show the work, do not show the answer.
Alpha is by application. The gate is fit, not seniority: we want decisions that are unambiguous, time-boxed, and recordable. Apply via the contact form and reference "alpha"; we will reply within two business days.
