Aderant

MADDI supplies model-based capabilities within Aderant's established law-firm business systems. askMADDI answers plain-language questions in Stridyn Analytics and the cloud general ledger, assists with guideline rules in Onyx and suggests time narratives in iTimekeep. Agent Center adds seven specialist agents that prepare billing appeals, prioritize collections, draft evaluations, recommend codes, explain rates and build forecasts.

Its early access program began in August 2026 and uses data from the products a firm licenses. Expert Sierra still runs accounting, matters, billing and expense workflows without those agents. The models therefore power important operational capabilities within a wider platform, rather than replacing the system of records or constituting the entire product.

The Compliance Agent identifies requirements in outside counsel guidelines and cites the underlying language when helping create and test billing rules. Other agents keep a record of the information used and work prepared, while askMADDI answers from the firm's financial and operational data. Aderant describes safeguards, validation and performance monitoring, but does not supply an error rate, test set or worked example that demonstrates how a reviewer opens every supporting source.

The relevant failures include an incorrect ledger answer, an unsuitable billing code or a misread client requirement. These are financial and contractual assertions rather than case-law citations. Source grounding is claimed for specific tasks, without enough detail to independently assess its reliability across the agent suite.

Agent Center prepares, prioritizes and drafts work for the firm's team to review and decide. Agents use authorized data from licensed products and follow existing product permissions and firm controls. Their record of source information and prepared work gives reviewers context for accepting or changing a result. The Harvey integration provides a concrete approval path: completed legal work becomes a draft iTimekeep entry, then a lawyer reviews, edits and submits it through the firm's normal process.

The agent descriptions stop at recommendations, draft messages and forecasts. They do not specify escalation thresholds, mandatory stops for uncertain answers or recovery after an incorrect recommendation. The firm's reviewers make the final operational decisions.

Chartwell Law's June 2026 customer story describes moving a nearly 300-attorney firm from internal infrastructure to Expert Sierra. Chief Information and Operations Officer Maor Levy explains the consolidation of billing, timekeeping and matter information, with Aderant managing the underlying cloud environment. That account supplies a named deployment and practical changes, without a measured before-and-after study.

Separate Expert Sierra testimonials attribute a reduction of more than half in prebill time to Holland & Knight and halved receipt-processing time to Kostelanetz. Those figures have no stated measurement period or method. Chartwell's AI discussion concerns evaluation and future adoption, so its migration results say nothing about how Agent Center or askMADDI perform.

Aderant states that confidential, intellectual property, personal and sensitive information is excluded from machine-learning training. Its data strategy instead uses aggregated, synthetic or customer-partnered material with masking and filtering. The API terms give Aderant a perpetual license to submitted content for providing, securing and improving the APIs and related services, without an express model-training exclusion.

That permission applies to API content and is not a complete confidentiality agreement for the cloud suite. The privacy notice separately excludes personal data processed on customers' behalf. Agents follow product permissions, but the specific matter-wall configuration and model-provider handling are not explained. These statements leave important contractual and segregation questions unresolved for privileged client material.

The AI supports business operations inside law firms: time narratives, billing appeals, collections, pricing, financial forecasts and associate evaluations. The product audience is finance, operations, talent and legal staff within a firm. Human review is part of the agent workflow and the Harvey time-entry integration. Neither those descriptions nor the API terms establish a specific boundary between software assistance and regulated legal advice.

The API terms require lawful use and respect for third-party rights, without connecting the AI features to lawyer competence, professional supervision or jurisdiction-specific duties. A firm's approval of a generated time narrative or interpretation of a client's billing guideline remains a professional decision; the product supplies no separate ethics or advice framework for it.

Aderant organizes its AI position around four principles: firm-centered design, responsible development, legal expertise and trust. It describes controlled orchestration, validation, quality monitoring and a data strategy using masking, anonymization and filtering. Lisa Erickson is identified as the executive responsible for product management and AI, but that title is not accompanied by a formal governance responsibility matrix or release approval process.

No assessment results show how the Talent Agent performs across different employee groups, despite its use of performance history and feedback to draft associate evaluations. Aderant publishes no bias test protocols or assessment results.

Agent access follows the permissions and controls in the firm's licensed Aderant products. Expert Sierra uses AWS hosting, security monitoring and auditing, while product-specific SOC 2 examinations cover security, availability and confidentiality. The trust center offers security whitepapers, penetration test reports, diagrams and subprocessor material through an access process. The open product material gives no specific deadlines for prompt retention, agent-log deletion, customer-data return or incident notice.

The privacy notice gives general retention and individual-rights provisions for data Aderant controls, while excluding its processing on customers' behalf. API users must protect their own end users and report unauthorized access as law requires; that obligation does not supply a cloud-service notification commitment from Aderant.

Aderant's API terms allocate losses for use of the Expert APIs and related developer services. They supply the APIs as is, disclaim reliability and content warranties, exclude consequential losses and cap liability at the amount paid for the applicable APIs during the preceding year. Business users indemnify Aderant for misuse, terms violations and content routed through their integration. The terms expressly recognize separate licenses and other product agreements, which can control conflicts.

They therefore provide a standard limitation for integration exposure rather than a warranty on MADDI output across the suite. No equivalent open subscription clause establishes AI accuracy remedies, an AI indemnity or insurance available to the customer for a wrong billing recommendation.

The Harvey connection moves completed work into iTimekeep as draft entries containing matter context, duration and a generated narrative. Lawyers can edit the draft before submitting it through their existing billing approvals. It became generally available in August 2026. A separate First AML connection brings due-diligence checks into Expert and Expert Sierra through Aderant's professional services team. Expert Sierra also connects practice and financial records within the Stridyn platform, allowing workflows to use those shared records.

The Expert API terms describe credentials, usage limits and permission to build client integrations, but do not serve as an endpoint reference or installation guide. Aderant does not document installation steps or permission mappings for these connections.

Expert Sierra is Aderant's AWS-hosted cloud practice and financial system. The self-hosted Expert product remains a distinct deployment, while Sierra adds Stridyn, newer financial applications and AI capabilities. Its cloud service includes infrastructure maintenance, security monitoring and platform upgrades, allowing customers to retain existing customizations and integrations during migration. The product page identifies AWS but does not specify a tenant-isolation model, available countries or where MADDI inference occurs relative to stored firm data.

Aderant's worldwide offices and the privacy notice's treatment of website information say nothing about where cloud customer data resides. The hosting provider and delivery model are clear; the regional and tenancy details required for a sensitive matter deployment remain unsettled.

Schellman & Company examined Expert Sierra, vi by Aderant and iTimekeep for SOC 2 Type 2 covering October 2024 through September 2025. A separate Onyx examination covers November 2025 through January 2026. Both announcements identify the security, availability and confidentiality criteria. Aderant's trust center offers the reports, security whitepapers, penetration test reports, network diagrams and a Cyber Essentials Plus item through an access process.

The underlying report contents are not openly available, and the announced examination scopes do not separately identify the suite-wide AI layer. The named auditor, dates and product boundaries provide more substance than a badge, while access restrictions limit independent review of the detailed controls and exceptions.

MADDI combines Aderant's domain-specific technology with enterprise model platforms. Its current description does not name those platforms, a model family or a version. askMADDI and the operational agents use the firm's data from licensed Aderant products, but Aderant does not name the processing provider or the inference location. AWS hosts Expert Sierra; that infrastructure fact alone does not identify the model serving its AI requests.

Harvey is a separately named integration partner that sends completed legal work into iTimekeep, not an identified foundation-model provider for MADDI. The trust center offers subprocessor material through an access process. No open commitment states when customers would be notified about a change of model or AI provider.

Expert Sierra is sold through a custom subscription proposal. Aderant's current cost explanation separates a fixed cloud subscription from one-time migration, implementation and training, with hosting and infrastructure maintenance included. Its product matrix distinguishes self-hosted Expert from Sierra's newer financial applications, Stridyn platform and AI capabilities. Neither that comparison nor the Agent Center material gives a starting figure, user allowance, usage charge or surcharge for particular agents.

Agent eligibility depends on the products already licensed. A historical Sierra FAQ described monthly subscriptions for small and midsize firms, which may not reflect today's rates or terms. The commercial shape is visible, while a buyer still needs a proposal to calculate current cost.

Law firms get practice finance, billing, collections, timekeeping, docketing and people management from Aderant. Expert Sierra includes client and matter records, conflict checks, trust accounting, tax, disbursements and financial reporting. Its customer examples include Chartwell Law, Holland & Knight, Kostelanetz and Meridian Lawyers, while separate tools address outside counsel guidelines and associate development.

That breadth concerns running a firm across practice groups, rather than supplying jurisdiction-specific legal analysis. The corporate legal department paying an outside firm is not the main buyer of these systems. No current minimum firm size or detailed eligibility matrix maps each agent to a license and customer segment. Product coverage is substantial, with some commercial and audience boundaries left to the proposal.
