AI for the deal that cannot be exposed.
Private AI for wealth advisors, family offices, CFOs, accountants, and the teams handling material non-public information every day.
AI is genuinely useful in finance — for portfolio analysis, deal modeling, tax planning, and audit work — but every prompt worth writing contains material non-public information. ArcaKey is the only AI environment built to be used on actual client portfolios, deal models, and tax returns: end-to-end encrypted, post-quantum, with keys you hold and a session that disappears the moment you close it.
Five ways finance uses Arca · Key every day.
01
The wealth advisor's quarterly review.
An RIA preparing for a meeting with a $20M client wants AI to surface tax-loss-harvesting opportunities by lot, model rebalancing against family liquidity needs, and draft talking points. Every prompt names the client, lists their holdings, references their tax bracket and family dynamics. ArcaKey is the entire prep workflow without ever exposing who the client is.
02
Estate planning for HNW and UHNW families.
Designing or stress-testing an estate plan involves successor trustees, GST considerations, business succession, philanthropic structures, and family-conflict patterns. AI is genuinely useful for modeling outcomes and surfacing missed issues. With a commercial LLM, that becomes training data; with ArcaKey, it's processed in TEE and gone.
03
The CPA in tax season.
A boutique tax practice running 200 returns. Each contains SSNs, dependents, asset schedules, foreign-disclosure flags. AI dramatically speeds up unusual-item review, K-1 reconciliation, and entity-structure analysis. ArcaKey makes that a 4× productivity win without putting a client's tax data on a third-party server.
04
CFO and corporate development.
Pre-announcement M&A modeling, board-prep with non-public financials, debt-covenant stress tests, activist-defense scenario planning. Every prompt is material non-public information. ArcaKey is the AI workspace for everything that would be a Reg FD problem if it surfaced in someone else's logs.
05
AML, KYC, and compliance investigations.
Investigating suspicious-activity reports, sanctions hits, KYC discrepancies on PEPs. The work itself names names — sometimes powerful ones. ArcaKey gives the team AI capability without the operational risk of those names sitting in a vendor's audit trail.
Built for.
Wealth advisors & RIAs
A 6-advisor RIA uses Teams Executive for client-portfolio analysis, financial-plan drafting, and meeting prep — with named CSM, SSO, and a signed data-handling addendum for client data.
Family offices & multi-family offices
A single-family office for a $250M+ family uses Sovereign for the principal and key advisors, with dedicated single-tenant infrastructure and a concierge implementation engineer.
CPAs, tax practices & boutique accounting firms
An 8-CPA tax practice uses Teams Professional during the season for unusual-item flagging, K-1 reconciliation, and complex-return drafting — encrypted memory across the engagement.
CFOs, treasurers, and corporate development teams
A pre-IPO company's CFO and corp dev team use Executive seats for board-prep, M&A modeling, and debt-covenant work, with role-based memory and Ghost Mode for the most sensitive sessions.
Boutique investment banks & M&A advisors
A 25-banker boutique uses Teams Executive for deal modeling, CIM drafting, and buyer outreach work, with dedicated infrastructure and SSO.
Compliance, AML, and internal audit teams
Bank compliance teams use Executive or Teams Executive for AML investigations and internal audit work — with exportable signed audit logs that withstand regulatory scrutiny.
Estate planners (financial side)
Estate-planning advisors collaborate with the family's attorneys using Teams Executive — encrypted memory across complex multi-generational planning engagements.
Knowledge Pack & Secure Search.
The Finance Knowledge Pack
Curated, pre-ingested reference content, queryable without ever leaving the vault:
- IRS Publications (selected — Pub 17, Pub 525, Pub 535, Pub 590, etc.)
- AICPA guidance and ethics opinions
- SEC/EDGAR filings feed (10-K, 10-Q, 8-K, S-1, proxy statements — searchable)
- Reg FD guidance and enforcement examples
- FINRA rules and regulatory notices
- State CPA ethics opinions and IRS Section 7216 guidance
- Selected tax-law updates (current year + prior two)
Zero external egress. Your queries against these references stay inside the encrypted environment. Current, relevant, and never exfiltrated.
Secure Search — Executive, Sovereign, Teams Executive, Enterprise
When you need information beyond the Knowledge Pack, — a recent enforcement action, a market event, an unusual security — Secure Search handles the outbound query privately:
- Scrubs email, phone, SSN, credit card, DOB, titled-person, and street-address patterns from the query before anything leaves the vault.
- Routes the scrubbed query through a sandboxed Brave Search integration — tenant-isolated, never pooled with other search traffic.
- Returns results with inline citations; raw query is not persisted beyond the request.
- Emits an Ed25519-signed proof-of-purge record (hashed scrubbed query + categories redacted + counts; never the values) usable for discovery-response attestation or internal audit.
- Self-hosted SearXNG variant for privacy-absolute workflows is on the Q2 2026 roadmap — Brave-backed path is live today for Executive+ accounts with a Brave API credential.
Google with the receipts — and none of the surveillance.
