Financial infrastructure · the account operating system

The operating system for financial accounts.

A8 Core™ is the unified account operating system for fintech, wealthtech, retirement, private markets, digital assets, and private funds — an API-driven platform that powers the complete account lifecycle, from investor onboarding and account opening to funding, investing, custody, administration, compliance, reporting, and settlement, across every account type.

Live API console: opening a self-directed Roth account, funding it in real time, and receiving an account.funded webhook.

The core, not another app

Most platforms sit on top of a core.
A8 Core™ is the core.

Fintech and wealthtech teams burn months stitching together account opening, ledgering, funding, and compliance. A8 Core™ delivers all of it as one API-driven, composable system — so you ship products in weeks, branded as your own, on infrastructure built for regulated workloads.

API-led connectivity

Every capability is an endpoint. Integrate account, client, and financial operations directly into your app, with webhooks for real-time, event-driven updates.

Composable services

Create, Manage, Update, Financial, and Utility services compose into whatever you're building — adopt the whole core or just the modules you need.

Real-time processing

Open, fund, and transact accounts through synchronous API calls rather than batch files. Rule- and profile-based push alerting keeps every system in sync.

Compliance controls

BSA, KYC, AML, OFAC, PCI and IRS control points are modelled in the platform, and create, read, update and delete operations are recorded to an audit trail.

One core · 45 account types documented

From demand deposit to private fund — natively supported.

Banking cores do banking. Wealth platforms do wealth. A8 Core™ does both, plus retirement and entity structures, so a single integration covers the full account spectrum for individuals and entities.

Demand Deposit Accounts
Checking, Savings & Time Deposits
Retirement Accounts
Individual & Separately Managed — IRA, Coverdell ESA, HSA, 401(k), and more
Taxable Accounts
For individuals and entities
Trust Accounts
For benefit of a 3rd party (individual or entity)
Private Fund Accounts

Beyond the account

Operational capabilities, built into the core.

The account core does more than hold balances. A8 Core™ folds in the operational machinery wealthtech and private-market teams normally stitch together from five vendors — identity, automation, signing, documents, and permissioned access — on one connected ledger.

Verified Identity Passport

Onboard once, reuse everywhere. A verified identity profile carries KYC, KYB, AML, and accreditation across every account and offering — no re-verification per product.

Investment & capital-call automation

Account holders connect funding sources once; contributions, investments, and capital calls settle and reconcile to the ledger automatically.

Built-in e-sign & subscription docs

A DocuSign-class signing flow is built in — generate, send, and execute subscription and account documents without leaving the platform.

Auto-filing secure data room

A permissioned document vault auto-files statements, tax forms, and agreements to the right account and party — your own secure, audit-ready document room.

White-labeled permissioned portals

Stand up management, account-holder, and representative/advisor portals under your brand — each with role-scoped, least-privilege access.

One connected source of truth

Every directive, document, balance, and party lives on one ledger. Connect fund admins, auditors, and counsel to the same data instead of reconciling silos.

Integrated payments & settlement

Connected banking, funding, and settlement close the transaction loop — payments and transfers settle and reconcile to the account without leaving the platform.

Investor relations & messaging

A lightweight CRM, in-app messaging, and automated status updates keep account holders and their representatives informed without back-office chase.

Tokenization module contract-dependent

For regulated digital-asset use cases, a separately contracted module supports the transfer-restriction standards used for regulated offerings (ERC-1404/3643) alongside the traditional ledger. Stablecoin accounts are reserved and not enabled.

Multi-tenant by design

Built to be white-labeled and resold.

A8 Core™ runs multiple financial institutions, custodians, administrators, and providers on one platform. Each provider's accounts are isolated, while a single client can hold accounts across many providers — multi-currency, including cash and digital — all under your brand.

  • Provider separation — an account is accessible to exactly one provider
  • Clients hold multiple accounts, including multiples of the same type
  • Multi-currency: cash, digital, and currency conversion
  • Flexible fee management and rule-based push subscriptions
For developers

A documented API surface, ready to integrate.

Security & compliance
