A-Alpha Bio

A-Alpha Bio measures how proteins bind to each other at enormous scale and uses that data to train AI that designs antibodies. It is based in Seattle and works with large pharmaceutical partners.

Two things sit at the center. AlphaSeq is a laboratory method that measures protein to protein interactions by the million, which the company says has produced the largest repository of such data in the world, more than a billion measurements across antibody and antigen pairs and other interaction types. AlphaBind is a set of machine learning models trained on that data to predict binding from a protein's sequence, with the designs it proposes then measured on AlphaSeq to check and sharpen the models.

The company applies this to discovering antibodies, finding degradable targets and engineering protein interfaces, and names blue chip collaborators including Bristol Myers Squibb, Amgen, Gilead and the Gates Foundation, alongside work funded by the United States Department of Defense on antibodies against biological threats. It raised a $22.4 million Series A2 to scale the data platform and its own pipeline.

What A-Alpha does not publish is a clinical program, a peer reviewed evaluation of how well AlphaBind designs, or any 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 work is done by a model. AlphaBind is trained on the company's interaction data to predict binding from sequence and to propose antibodies, and that prediction and design is the capability a partner comes for. It sits on top of AlphaSeq, the measurement platform, which is real value in its own right and the source of the data, so the company is not only its models. But the thing that turns measurements into a designed antibody is the learned model, and that half of the business does not exist without it.

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

A-Alpha runs a loop a partner can follow: the model proposes a design, AlphaSeq measures it, and the measurement feeds back to validate and refine. What the loop does not come with is a stated control, when a prediction is trusted or set aside, what a contradicting measurement does to a program, and which calls a person makes. The experiment is the oversight, which works in practice but is not written down as a rule.

BB on Model and Technology TransparencyThe approach or the suppliers are named without the version and update discipline behind them. Naming a supplier is the entry to this band both here and on Model Supply Chain Disclosure, which ask different questions of the same disclosure: who receives the data, and what produces the output.
Vendor Published

The model is named and its approach is clear. AlphaBind is a set of models trained on the company's own protein interaction data to predict binding from sequence, and the relationship to AlphaSeq, which generates that training data, is described. What is not published is the layer beneath: no architecture, parameter count or training data size is given, and no version or update practice ties a design to a dated model.

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 models and the measurement platform are the company's own, and no outside model provider is named as sitting between data and a design. 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 partner's data once it enters the system.

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

The evidence is a roster of serious partners and a large measured dataset, with no clinical result yet. A-Alpha names collaborators including Bristol Myers Squibb, Amgen, Gilead and the Gates Foundation, work funded by the United States Department of Defense on antibodies against biological threats, and more than a billion protein interactions measured on AlphaSeq.

What is missing is a program from the platform named in a clinical trial and a peer reviewed evaluation of how well AlphaBind designs, so the checkable signal is who works with the company and how much data it holds, not an outcome in a patient.

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

The inputs are protein and interaction data rather than patient records, so no protected health information is involved. What a collaborator would want settled is the fate of its own data on a platform whose value is a shared pool of measurements: whether that data is retained, used in training, or kept apart from other work. A-Alpha does not describe how any of that is handled.

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

A-Alpha works with protein interaction data rather than patient records, so United States health privacy rules do not touch what it handles. No business associate position and no platform level privacy document are published, which a pharmaceutical partner's data review would note even though no patient data is in play.

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

Large pharmaceutical partners hand A-Alpha their data, the kind of relationship where a security team expects an attestation it can open: a SOC 2 report, an ISO 27001 or HITRUST certification, or at least a trust portal. The company names none of these and runs no security page, so there is no outside account of how that data is protected.

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. A-Alpha works at the discovery stage, measuring interactions and designing antibodies, so any regulatory position belongs to the molecules and the partners that develop them. 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

The company's account of its model is a method, that measured data from AlphaSeq validates and refines the models. A buyer judging governance needs the next thing, an evaluation of how reliably those models predict and where they fail, a benchmark, an audit, or a responsible AI policy. The method of refining on measured data is not that evaluation, and none of those governance artifacts appears.

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

When an AlphaBind prediction does not pan out, a partner wants a sense of how often that happens and what recourse exists. No success or error rate with a method and a denominator is published, so there is no figure to plan against, and no guarantee, indemnity or correction route travels with a design. That risk is settled inside the private collaboration agreements.

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 platform is a measurement method paired with a set of models, not software a buyer wires into a stack, so there is no clinical record surface involved, as a discovery platform would not have one. The research side is just as self contained: no electronic lab notebook, laboratory information management system or research data platform is named as connected, and no connector is offered.

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

The platform runs for A-Alpha and its partners rather than being deployed to anyone, so there is no tenancy or hosting model to evaluate. Location is implied by the company's base in Seattle rather than committed, and nothing published names where partner data rests or how one collaboration's data is kept apart from another's on the shared data 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

A-Alpha earns through partnerships and funded programs rather than selling access, so no price is posted. The public figures, a $22.4 million Series A2 and a $14.5 million Department of Defense award, are money raised rather than a price a buyer could pay, so the way the company funds itself is visible while the cost of engaging it is not.

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

Coverage is named by interaction type, with the measured data behind part of it. A-Alpha works on antibody and antigen pairs, on degrader targets described as E3 ligase and neo-substrate interactions, and on engineering protein interfaces generally, and reports having measured those interaction types at scale.

What is not established is therapeutic reach: no disease area, indication or clinical program is named, so the coverage is described in terms of the biology it measures rather than the conditions a drug would treat.
