Seb now leads the pitch: a family workspace with specialist agents for contribution patterns, portfolio reviews and family learning that drafts review briefs for an institution's team. The collaborative child investment Nest, contributor invitations and white label apps would still work without it.

Education and planning support is Seb's stated role: it refuses and hands off requests for advice and works from approved content and institution context. Staff set each agent's scope and permissions and review its briefs before deciding next steps.

Deterministic calculations kept apart from the language models keep arithmetic out of generated text. Accuracy, evaluation and error analysis for Seb's briefs and portfolio review agent are unpublished.

Not one live institution is named, and no user, account or asset figure is published. Going live in weeks, compounding household assets and higher heir retention are promised without a number or deployment behind them.

Content will not train unrelated general purpose models without appropriate authorization and disclosure, a commitment qualified twice, with tenant separation between institutions. External AI providers sit under contractual controls but are not named, so whether one institution's family data improves models serving another stays open.

The August 16, 2026 privacy notice reaches the institutional service: processor role on documented instructions, retention and deletion under the customer agreement, and transfers outside the European Economic Area on adequacy or standard contractual clauses. Child facing features need verifiable parental consent under 13 in the United States, and children's data is barred from behavioral advertising, with no subprocessor list alongside.

Role based access, encryption and controlled administration are listed, with detailed evidence shared only with qualified institutions. Neither an attestation nor a certification is named, on a platform holding children's financial data under an institution's brand.

Investment recommendations, financial advice and credit decisions are all outside Seb's remit, according to the privacy notice. Brokerage, onboarding and identity checks sit with the institution and its regulated providers, none of whom is named.

Household asset growth and heir retention are what the firm sells, and the family experience includes learning for children, which places the bias surface in the objective and the audience. Approved use cases, visible assumptions and human escalation are described, but no evaluation of how guidance varies across families is published.

Review by the institution's team sits between the model and any decision. A family that acted on misread guidance has no published correction route, guarantee or indemnity behind it.

A choice of large language models powers Seb, and an in house model for family wealth is in development. Model providers, custody partners and hosting are not named.

An overlay or native integration brings bank account context into Seb's workspace, with cards and investing under the institution's brand. No core banking platform, custodian or card issuer is named, and developer documentation is not public.

Based in Ireland, the firm may use providers in the United States and elsewhere under adequacy decisions or standard contractual clauses. Hosting provider, region and residency are not stated for family and children's data held across both regimes.

Institutions are routed to a demo, and deployment steps from scoping through white label launch are described, but nothing is priced. Per member, per family or a platform fee could each apply.

Credit unions, community banks and wealth advisers each get homepage material, with a dedicated credit union solution page, across the United States and Europe. Registered investment advisers and platforms are also named buyers.
