Scala Biodesign

Scala Biodesign makes software that redesigns proteins to work better, and sells it both as a cloud platform and as a design service. It is based in Tel Aviv.

The platform, ScalaOS, aims to improve a protein in a single design round by introducing many beneficial mutations at once. It works across enzymes, therapeutic antibodies and antigens, targeting things like expression in simple organisms, thermostability, shelf life, catalytic activity, and antibody developability, manufacturability and humanization. The company describes the approach as powered by evolutionary data, atomistic physics and AI together, rather than by a model alone.

Scala names a set of industrial and pharmaceutical users, among them BASF, Boehringer Ingelheim, Teva, Repsol and the Weizmann Institute, and points to case results such as a sevenfold increase in the conversion rate of an enzyme in one design round. It was founded by chief executive Ravit Netzer, chief technology officer Adi Goldenzweig and chief scientist Sarel Fleishman.

The company sells access to ScalaOS or partners on a design project. It publishes case studies rather than peer reviewed papers on the platform itself, and no security or data handling documentation.

Capability Axes

An AI Health Index grade measures what a buyer can verify from public sources on the date shown. It is not a rating of how good the product is. A vendor can build an excellent system and grade low on an axis because it publishes nothing an outsider can check. How grades read

AI Capability
BB on AI CentralityThe model is the engine of a core module. The platform carries other value, but this capability does not exist without it.
Vendor Published

The design engine is the product. ScalaOS takes a protein and proposes a redesigned version, and selling or partnering on that is the whole business. The company is explicit that the engine runs on three things together, evolutionary data, atomistic physics and AI, so the learned model is one part of the method rather than all of it. The product does not exist without the engine, and the engine is not a model alone.

CC on Autonomy and Oversight ModelAutonomy is claimed and oversight is asserted without a mechanism. Human in the loop appears as a phrase rather than a described control.
Vendor Published

The platform proposes designs, and the customer then expresses and tests them in its own lab, which is where the checking happens. Inside the software itself there is no described control: where a person reviews or overrides a proposed design, what the system does when one fails at the bench, and which steps run without a human are not set out. The testing is real but it sits in the customer's workflow rather than being a control ScalaOS defines.

CC on Model and Technology TransparencyThe architecture is described in general terms with nothing identified. Proprietary is asserted rather than explained.
Vendor Published

The method is named and described in general terms. ScalaOS is said to combine evolutionary data, atomistic physics and AI to introduce many beneficial mutations in a single round, which conveys the approach without naming a model, giving an architecture or parameter count, or characterizing the training data. No version or update practice ties a given design to a dated system.

CC on Model Supply Chain DisclosureThe architecture is described and no model provider is named. Naming a hosting provider alone does not lift a record out of this band. Record the host in the note, because it matters for residency and breach scope, and grade on the model layer, which is the question this axis is named for.
Vendor Published

The platform is presented as the company's own cloud software, and no outside model provider is named as part of it. Beyond that nothing is established: no compute or hosting provider is named, no third party components are listed, there is no subprocessor list, and nothing describes what governs a customer's protein data once it enters ScalaOS.

BB on Clinical and Operational EvidenceNamed deployments with dated outcome figures and enough method to test them, or published research short of independent validation.
Vendor Published

There is industrial and academic validation, short of peer reviewed platform papers. Scala names users including BASF, Boehringer Ingelheim, Teva, Repsol and the Weizmann Institute, points to more than a hundred scientific publications associated with the underlying method, and publishes case results such as a sevenfold increase in an enzyme's conversion rate in one design round and a stabilized vaccine antigen.

What is missing is a peer reviewed evaluation cited directly for the platform and, for therapeutic uses, a clinical outcome: the evidence is named customers and case studies rather than a controlled result a reader can check in full.

DD on AI Safety and PHI StewardshipNothing published on how protected information moves through the system.
Vendor Published

A customer uploading its own proteins to ScalaOS would want to know what happens to them: whether the sequences and structures are retained, used to train the engine, or kept separate from other customers' data. Scala does not describe this. No patient records are involved, so protected health information is not in play, but the handling of a customer's uploaded proteins is left unstated.

Regulatory and Compliance
DD on HIPAA and BAA PostureNo statement of status and no privacy document that reaches the product. Both halves are absent at this grade: a service level privacy document on its own lifts a vendor to the band above even where no status is stated. A website privacy notice, including one that says it does not cover customer data, does not reach the product, so a vendor whose only document is that notice and who states no status grades here.
Vendor Published

ScalaOS takes in protein sequences and structures, not patient records, so United States health privacy rules do not apply to what it processes. Scala states no business associate position and publishes no privacy document reaching the platform service, so a customer uploading proteins has nothing on this to read.

DD on Security Certifications and Trust CenterControls are asserted with nothing independent behind them, or nothing is published. Read the note before concluding anything: this is the grade most often corrected on a second pass, because assurance material frequently sits on a parent domain or inside an old announcement rather than on the product pages.
Vendor Published

ScalaOS is a cloud platform that takes in customers' proprietary proteins, so a customer's security reviewer would look for an independent attestation: a SOC 2 report, an ISO 27001 or HITRUST certification, or a trust portal. Scala offers none, and there is no security page, so the way the hosted environment is secured is not attested anywhere public.

CC on FDA and Regulatory StatusNo device claim is made and the product is scoped accordingly. Most administrative and operational products sit here and are not penalized for it, because this axis grades the appropriateness of the positioning rather than possession of a clearance.
Vendor Published

No device claim is made, and the platform is scoped to match. ScalaOS redesigns proteins at the research and development stage across industrial and therapeutic uses, so any regulatory position belongs to the products its customers build rather than to the design software. There is no clearance to hold and none is claimed.

DD on AI Governance and Bias DisclosureNothing published on how model behavior is governed or tested. Multilingual operation with no subgroup performance sits here when the vendor markets recognition quality as a strength, because a caller the system failed to understand leaves no complaint and no record.
Vendor Published

What Scala shows about the engine is a set of successful redesigns in its case studies. Governance would call for something broader, an evaluation of how often the platform succeeds or fails across a range of proteins, a benchmark, an audit, or a responsible AI policy. A handful of wins is not that measure, and none of those governance artifacts is published.

DD on AI Liability and RecourseNothing published on what happens when the system is wrong.
Vendor Published

A customer that expresses and tests a ScalaOS design carries the cost when it does not work, so the natural questions are how often designs succeed and what the company stands behind. The case studies report wins rather than a success rate with a method and a denominator across attempts, and no guarantee, indemnity or correction route comes with a design, so the risk stays with the customer running the experiments.

Integration and Deployment
DD on EHR and Interoperability DepthNo integration evidence. A connector described as available on request grades here until one exists.
Vendor Published

The product is reached as its own cloud application, not something a customer folds into existing systems, so there is no clinical record surface, as a protein design tool would not need one. Nor is there a research side link: no electronic lab notebook, laboratory information management system or research data platform is named as connected, and no connector or application programming interface is offered.

CC on Deployment Model and Data ResidencyA single hosted option with location implied rather than committed.
Vendor Published

The software is offered as a single cloud platform, so there is a hosted model but no stated options or isolation to evaluate. Location is implied rather than committed: nothing published names the region a customer's protein data rests in or describes tenant separation between customers sharing the platform.

Commercial
CC on Commercial TransparencyNo price is published and the posture is discoverable: a buyer can establish how the product is sold and what drives the cost before contacting the vendor. Most of the index sits here.
Vendor Published

Scala sells in two ways, access to the ScalaOS software or a partnership on a design project, and points a buyer to a demo request or its scientists for either. What it does not carry is a number: no rate card, tier or unit of charge appears, so the routes to buy are clear while the cost of either is not.

BB on Setting and Specialty CoverageCoverage is named with validation behind part of it.
Vendor Published

Coverage is named across several protein classes, with case studies behind part of it. ScalaOS is applied to enzymes, therapeutic antibodies, other therapeutic proteins and antigens, and to specific properties within each, expression, stability, catalytic activity, developability and humanization, and the company shows worked examples such as an enzyme conversion improvement and a stabilized vaccine antigen. What is not established is validated breadth across every claimed class, since the examples cover a few cases rather than the full range.
