Pillar 01 | Network
Card-Agnostic Overlay
Heimdall issues nothing. It taps the Amex and Chase cards your treasury already runs, listening on low-latency global network webhooks. The swipe reaches our decision engine before the terminal prints.
Autonomous spend enforcement
The All-Seeing Eye of Corporate Finance.
Heimdall taps the Amex and Chase cards your company already carries. Vision-AI intercepts swipes, splits personal spend, and verifies physical assets in real-time.

01 | The four pillars
Enforcement at the swipe, not the audit.
Expense reports reconstruct what happened weeks later. Heimdall decides inside the transaction window, while the card is warm and the asset is in hand.
Pillar 02 | Lifecycle
Milestone-Bound Spend Tokens
Spending authority is tied to active project milestones in Jira, Asana, and Procore, never to arbitrary calendar dates. Milestone marked complete: the virtual card authorization terminates that instant.
Pillar 03 | Vision
Multimodal Vision-AI Audit
Vision models cross-examine receipt line items against the physical unboxed item in the same submission: extracting manufacturer data and serial numbers, and flagging unapproved goods before they reach a ledger.
Pillar 04 | Ledger
Personal-Corporate Split Engine
A jacket on the same receipt as the drill is not an expense-report argument. The AI itemizes the receipt, bills approved goods to the corporate ledger, and charges the personal remainder to the employee's pre-linked personal debit card. Automatically.
02 | The post-swipe validation loop
Four phases. One swipe.
From authorization to a locked, split, asset-twinned ledger entry in under five minutes. Select a phase to inspect its record.
Phase 01 of 04 | The Trigger
A swipe on Apple Pay opens a case file.
The employee pays exactly as they always have. Authorization clears the network and the Fidel / Mastercard notification reaches Heimdall inside 100ms: merchant, amount, issuer, and the active milestone the card is bound to, all attached before the terminal finishes printing.

03 — Industry telemetry
Built for spend that leaves the office.
Field-heavy industries lose the most to unverifiable spend. Select an operating environment to inspect its telemetry.
Site pours don't wait for finance.
Field crews buy what the job needs when the job needs it. Heimdall binds every card to the pour schedule in Procore, registers every tool serial at the register, and kills subcontractor spend the second their phase closes.
