Polly

Polly runs a mortgage capital markets platform for United States banks, credit unions and mortgage lenders, built around a cloud native product, pricing and eligibility engine, alongside a loan trading exchange, a lender analytics product and a partner platform. The pricing engine carries loan products from hundreds of investors across conforming, government, construction, housing finance authority, non conforming, non qualified mortgage and portfolio categories, automates lock desk workflows including locks, extensions, relocks, repricing, price exceptions and float downs, and maps standard and custom fields into a lender's loan origination system through its interfaces.

Polly AI, launched in May 2024, sits on top of that engine. Its first application is a loan officer agent reachable by instant message or voice on web and mobile that examines near miss eligibility and near miss pricing, interprets the mathematical and logic based statements explaining why a loan is ineligible, and returns specific suggested actions, so an officer can find the closest qualifying product rather than simply learning that the loan does not fit.

The company reports that more than 1,250 employees at New American Funding actively use the platform and that it has provided clarity on over 7,200 ineligible products there, and that ResiCentral tripled year on year volume in 2024 without adding secondary, capital markets or lock desk staff. American Financial Resources adopted the pricing engine in 2025. Founded in 2019 and headquartered in San Francisco, Polly raised a 37 million dollar Series B in 2022 and a further 25 million dollars in 2024, and employs a dedicated team of AI engineers. It publishes no security certification, no model documentation and no pricing.

AI Capability
AI Centrality
CC on AI CentralityArtificial intelligence is present but peripheral: a feature layer on a product whose value stands without it.
Vendor Published

The removal test leaves the whole business standing. Strip the artificial intelligence and the pricing and eligibility engine still carries hundreds of investors' products, still runs automated lock desk workflows, still maps into the lender's origination system, and the loan trading exchange and analytics products are untouched. That engine is rules and eligibility logic evaluated against loan attributes, which is deterministic work, and it is what customers buy.

The intelligence line is genuine and sits inside the operation rather than beside it, since the loan officer agent reasons over the engine's own ineligibility logic to surface the closest qualifying product and directly changes what a borrower is quoted, but it arrived in 2024 on top of a platform that already worked. That is a real embedded intelligence line in a platform whose core is not learned, which this index builds at this grade.

Autonomy and Oversight Model
CC on Autonomy and Oversight ModelAutonomy is claimed and oversight is asserted without a mechanism, or full automation is presented as the entire disclosure. Human in the loop appears as a phrase rather than a described control.
Vendor Published

No control is described at any point, and the material asserts an outcome instead. The agent examines near miss eligibility, interprets ineligibility logic and proactively articulates specific recommended actions, and the only assurance offered about its operation is a customer's observation that it enhances rather than replaces the human connection, which is a description of intent rather than a mechanism.

Nothing states a confidence threshold below which the agent declines to recommend, what happens when it misreads an eligibility rule, whether a recommended price is verified against the engine before an officer repeats it to a borrower, or whether any category of recommendation requires review. The stakes make the silence conspicuous: the output is a price and a product recommendation that reaches a consumer through a loan officer.

Model Risk Management and Transparency
CC on Model Risk Management and TransparencyTransparency is claimed in general terms with no mechanism a model validator could interrogate.
Vendor Published

Nothing measurable is published about how the models behave. The material describes the technology in category terms, citing artificial intelligence, machine learning and natural language processing alongside proprietary technology and data, and offers no accuracy rate for eligibility interpretation, no error rate on near miss identification, no evaluation results, no retraining cadence, no artificial intelligence management system certification and no validation documentation.

The contrast within this pocket is instructive rather than incidental: competitors in loan level mortgage analytics compete substantially on documentation, published back testing and validation resources, and this vendor publishes none of it while making the strongest artificial intelligence claims of the group.

Operational and Outcome Evidence
AA on Operational and Outcome EvidenceNamed customers with hard performance figures and enough method to test them.
Vendor Published

Named institutions appear beside specific measured results, which is the bar. ResiCentral, a wholesale mortgage company, is reported to have tripled year on year volume in 2024 without adding secondary, capital markets or lock desk staff, which is an outcome stated in a form that would be visible to the customer and awkward to overstate.

At New American Funding, a large national lender, more than 1,250 employees are stated to be actively engaged with the platform and it is credited with providing clarity on more than 7,200 ineligible products, and a named manager at the company is quoted describing the change in how officers quote. A third lender, American Financial Resources, is named as adopting the pricing engine in 2025.

Venture backing adds parties with money at stake, with a 37 million dollar Series B and a further 25 million dollars raised. The residual weakness is that every figure reaches the reader through the vendor's own announcements rather than a channel the customer is accountable for.

AI Safety and Data Stewardship
CC on AI Safety and Data StewardshipGeneral assurances that do not answer the question this axis asks, which is whether one customer’s data trains models serving its competitors. Unbounded cross client learning stated with no boundary grades here too.
Vendor Published

No safety practice, output screening, red teaming or data boundary is described. The multi client question is unusually pointed here because of what the platform holds: pricing strategy, margin settings and lock behaviour for lenders who compete directly with one another, alongside product and pricing data from hundreds of investors.

Nothing states whether one lender's pricing behaviour informs recommendations produced for another, whether a lender's configured strategy is isolated from the models, or what happens to that data when a lender leaves. A vendor in this same pocket answers precisely this question by stating its agent is trained only on its own materials, so the question is answerable and this vendor has not answered it.

Regulatory and Compliance
GLBA and Data Privacy Posture
CC on GLBA and Data Privacy PostureA standard privacy policy that covers the website rather than the service, or silence on a product that touches limited consumer data.
Vendor Published

No privacy policy detail, processing agreement, subprocessor list or retention schedule was located. The engine evaluates loan level borrower attributes to determine eligibility and price, which places credit, income and property characteristics inside the system for consumers who never chose this vendor and will never know it was involved.

Nothing states how long pricing scenarios and lock records are retained, what a lender can require to be deleted, or whether borrower attributes submitted for a quotation that never becomes a loan are kept at all.

Security Certifications and Trust Center
CC on Security Certifications and Trust CenterA single footer line, or certifications asserted without being enumerated, which is weaker than naming them because it invites an assumption a buyer cannot check.
Vendor Published

No certification, attestation, trust centre or security page was located, and the absence is recorded as unlocated rather than proven. The data position makes it a live question rather than a formality: the platform holds borrower eligibility attributes and lock positions for national lenders, and separately holds the pricing and margin behaviour of institutions that compete with one another.

Buyers here include banks and credit unions whose own third party risk processes require documented evidence before onboarding, so this is a gap a purchasing committee would raise immediately. Worth one targeted check.

Regulatory Status and Licensure
CC on Regulatory Status and LicensureThe regulatory position is unstated. Most vendors in this index are technology suppliers and being unlicensed is the correct posture, so this grade records silence about the posture, not a missing licence.
Vendor Published

The company is a technology provider to licensed mortgage lenders and holds no licence, registration or supervisory standing of its own in anything located, which is the ordinary and unpenalised posture for this shape. No regulator engagement, examination or industry accreditation was found.

Its position sits adjacent to supervised activity, since pricing, eligibility determination and lock desk practice are all subject to examination at the lender, and the vendor supplies the mechanism without being examined itself.

AI Governance and Bias Disclosure
CC on AI Governance and Bias DisclosureResponsible artificial intelligence committed to in policy language with no evaluation behind it, on a product whose bias surface is modest.
Vendor Published

No fairness evaluation, differential outcome analysis or governance disclosure appears, and the exposure here is as direct as this index encounters. The agent recommends which product a borrower should be offered and at what price, and near miss reasoning specifically identifies borrowers who fall just outside a product's criteria and suggests actions to bring them inside it.

Which near misses the system surfaces, and which it does not, is a determination about who gets offered a better product. Fair lending is the most closely supervised area of United States mortgage and nothing published examines whether recommendations, near miss identification or suggested actions distribute evenly across borrower characteristics, geographies or channels.

AI Liability and Recourse
CC on AI Liability and RecourseMechanisms that enable challenge, such as audit trails and source traceability, with nothing standing behind the output and no route for the person affected.
Vendor Published

No liability position, error rate, remediation commitment or correction route is published. The consequence path is short and concrete: the agent generates a price and product recommendation, a loan officer relays it to a borrower, and a wrong eligibility interpretation means a consumer is quoted a product they cannot have or is not shown one they could.

Nothing states who bears that, whether the lender or the vendor stands behind a quoted price the engine produced, or by what route an error is identified and corrected once a borrower has acted on it. The borrower has no relationship with the vendor and no way to know it was involved.

Integration and Deployment
Model Supply Chain Disclosure
CC on Model Supply Chain DisclosureThe architecture is described and no provider is named.
Vendor Published

No model provider, family, version or hosting arrangement is named. The description consistently pairs artificial intelligence and machine learning with proprietary technology and data, which is the pattern this index has recorded repeatedly, where vendors that license their model capability name suppliers and vendors that call it proprietary name nobody.

The natural language and voice interaction the agent offers is exactly the kind of capability a company of this size would ordinarily license, and a lender cannot tell from published material whether borrower scenarios typed or spoken into the agent pass through a third party.

Core Systems and Integration Depth
BB on Core Systems and Integration DepthNamed systems or a documented public API, with the depth or the production evidence left open.
Vendor Published

The right system of record is named as a category and the specific products are not. The engine maps both standard and custom fields directly into the lender's loan origination system through published interfaces, which is the correct integration target for pricing and lock workflows and is more than a generic connectivity claim, and a separate partner platform extends the ecosystem.

On the supply side the engine ingests and maintains product and pricing data from hundreds of investors, which is a substantial integration burden in its own right and is quantified. Held off the top grade because no origination system, servicing platform or investor system is identified by name, no integration count or certified partner directory was located, and no public interface documentation was found.

Deployment Model and Data Residency
CC on Deployment Model and Data ResidencyCloud only with nothing stated, which is the category norm.
Vendor Published

Cloud native is the only deployment statement, repeated throughout as a differentiator against older on premises pricing engines, and it describes an architecture rather than a location. No hosting region, residency commitment, tenancy model or single tenant option is published, and nothing states whether lenders competing in the same markets share infrastructure. Availability on web and mobile is described as a user convenience with no accompanying statement about how data is handled on a device.

Commercial
Commercial Transparency
CC on Commercial TransparencyNo price is published and engagement runs through a demo form, which is the norm in this index.
Vendor Published

No price, tier, minimum or billing basis was located. The platform is described as offering near infinite configurability and unlimited flexibility through customisable options, which signals a configured enterprise sale and leaves a buyer unable to tell whether charging is per user, per lock, per loan, by volume or by subscription. Those imply materially different economics for a lender whose volume swings with rates, and the implementation effort implied by that configurability is never sized either.

Institution and Segment Coverage
BB on Institution and Segment CoverageNamed segments with dedicated material behind part of the coverage.
Vendor Published

The buyer set is genuinely varied within its market and the market is narrow. Banks, credit unions, independent mortgage lenders, wholesale operations and the brokers they serve all appear, and the named references span a large national retail lender, a wholesale company and a further national lender, which is three distinct operating models rather than one described three ways. Hundreds of investors have products carried on the engine, which is a distinct form of reach on the supply side.

Held off the top grade because coverage is bounded to a single asset class and a single country, with nothing outside United States residential mortgage, and because no client count, volume figure or market share is published to size the adoption.
