ReadBuyer’s guide
Most industrial AI in pharma is analytics with a chat box. The separating questions are simple: does it perceive the crystal, does it act, and can quality approve what it did?
Landscape
A simplified view of the categories teams compare us against.
| Category | Perceives the crystal | Acts on the plant | GMP record |
|---|---|---|---|
| DCS / automation platforms | No | Yes (fixed logic) | Partial |
| PAT software suites | Yes (single modality) | No | Partial |
| Industrial AI analytics | No | No | No |
| MES / eBR systems | No | No | Yes |
| Polymorra | Yes (fused) | Yes (bounded) | Yes (Part 11) |
The autonomous loop
Polymorra closes the loop around the reaction mass and the crystal — the two things a conventional DCS cannot actually see.
Fuse Raman, FBRM, PVM in-situ imaging, NIR, and reactor telemetry into a live picture of the reaction mass, slurry, and solids.
Plan the react-and-charge, crystallize-and-seed, and isolate-and-dry moves for this batch against the target polymorph, particle size, and purity.
Run with adaptive control: cooling and antisolvent profile, seeding, supersaturation, agitation, addition rate, and endpoint.
Predict polymorph, particle size and habit, impurity profile, and yield in-line — before offline XRPD and HPLC confirm it.
Optimize yield, solvent use, cycle time, and reprocessing risk across the campaign, then flag off-spec and polymorph risk early.
Write an immutable Part 11 record; every chemist correction trains the site model and compounds the data moat.
Plant-edge console
Supersaturation, particle size distribution, predicted polymorph, impurity trajectory, and the next control move — with the evidence behind each number.
Polymorra plant-edge console showing live supersaturation, particle size distribution, predicted polymorphic form, and impurity trajectory for a running crystallization, with the recommended next control move.
Integrations
Polymorra reads and writes through the reactor DCS, PAT instruments, crystallizer and isolation skids, historians, and MES you already validated.
Trust & compliance
Polymorra is engineered for regulated drug-substance production: grounded outputs, immutable audit trails, graduated autonomy, and validation documentation from day one.
Immutable, validated audit log for every agent perception, recommendation, and control action, with e-signature-ready review flows.
Change control, validated model versioning, and deployment documentation designed for drug-substance manufacturing.
SOC 2 Type I in progress, Type II on the roadmap; SSO/RBAC, encryption in transit and at rest. [ASPIRATIONAL]
Per-tenant isolation of routes, recipes, spectra, and crystal images. No cross-tenant training. On-prem option.
Shadow → assist → bounded auto-control. Every autonomy level is explicitly configured, bounded, and revocable.
Every recommendation cites the spectra, images, telemetry, SOP, or specification it was derived from.
Inference runs on-site so control loops survive network loss; cloud is for training, fleet, and analytics.
Chemist and QA checkpoints are first-class: approve, correct, or reject — and every correction trains the models.
Voices from the plant
Composite quotes from design-partner discovery interviews. [PLACEHOLDER — to be replaced with named references post-pilot]
“The crystallization step is where our campaigns live or die. Seeing supersaturation, particle size, and predicted polymorph in one place — and having the profile adjust itself — is what we have wanted for twenty years.”
“We do not want another dashboard. We want the batch to come out right and the record to be reviewable by exception. That is the only pitch that gets past QA.”
“Tech transfer is our bottleneck. If the twin can predict the plant crystal from the lab crystal, that is worth more than the software costs.”
Start with one crystallizer or reactor train. Prove polymorph, yield, and reprocessing ROI in a validation-friendly pilot. Then expand across the plant.
