Receipts beat reassurance.
Banks already know your model is a black box. BLKBXS gives AI startups a way to stop selling trust as a claim and start shipping receipts.
Primitive
INK Receipts
The open specification for signed, portable evidence receipts. Vendor-neutral. Verifiable without a platform.
Developer surface
BLKBXS
Free SDK, paid Evidence Bundle API, and enterprise control plane. The path from receipt to bank-review packet.
Institutional parent
Bankabil
The evidence-infrastructure doctrine for regulated finance. Sets the standard the packets speak to.
The bottleneck was never the model.
AI startups selling into banks lose months to diligence: vendor risk, model risk, security, procurement, legal, audit. Every bank asks the same questions in a slightly different form. Every answer is a custom deck.
The evidence already exists inside your stack. Traces, evals, policy checks, approvals. What doesn't exist is a way to hand a bank reviewer one packet and get on with the pilot.
BLKBXS is that packet.
