Hound your AI bill.
Before it hounds you.
CapHound brings FinOps governance to AI spend — real-time cost attribution, budget enforcement, and decision auditing for every LLM call your business makes.
01 · Enforce
Block runaway spend before it lands on the invoice
CapHound evaluates every request inline — before it hits your provider. When a budget is exceeded, the request is blocked. Not flagged for someone to review later. Blocked, in real time.
Hard budget caps
Set monthly limits per team, feature, customer, or environment. CapHound enforces them in real time — no human in the loop required.
Runaway protection
A retry loop fires 4,000 calls. CapHound catches the first 50, blocks the rest. The bug becomes a quiet incident — not a five-figure invoice line.
Tiered alerts
Get notified at 80% and 100% of budget over Slack or email. Finance and engineering see the same data at the same time.

}02 · Attribute
Every AI dollar mapped to a team, feature, or customer
When finance asks where the AI bill went, you have a real answer — broken down by the dimensions FinOps actually uses. No spreadsheets. No guesswork.
Feature
chat, search, summarization, classification
Team
product, growth, internal tools
Customer
per-customer cost allocation, chargeback
Environment
production, staging, dev
03 · Allocate
Finance sees Business Unit. Engineering sees Service.
CapHound maps AI spend to the dimensions your finance org actually uses — showback by cost center, chargeback by customer, custom groupings with no tagging mandate on engineering.
Custom dimensions
Define Business Unit, Product Line, or Cost Center. AI spend rolls up automatically. No changes to how engineers tag requests.
Showback & chargeback
Show each team their monthly AI spend. Export a clean chargeback report for finance in one click — no spreadsheet required.
Tag normalization
Engineers tag inconsistently. CapHound normalizes the variants — 'cs-chat', 'customer-support', and 'cust-support' all become the same canonical value.

04 · Govern
Define the rules. CapHound enforces them.
Write the policies that match your business. Dev should use cheap models. Free users get the cheaper tier. When the budget tightens, downgrade automatically. CapHound enforces it on every request.
Environment routing
Force cheaper models in dev and staging. Best models only in production. Zero application code changes — it's a server-side policy.
Tier-aware routing
Free users hit the efficient tier. Paid customers get full capability. Your business rules, enforced inline, never in app code.
Budget-pressure downgrade
When spend approaches the cap, CapHound automatically downgrades to a cheaper model. No human intervention. No production fire-drill.
One control layer. Every provider.
Cost attribution, budget enforcement, and policy governance — across every AI provider you use, from a single integration.

Enterprise-ready from day one
Every workspace is hard-isolated at the database layer — Postgres row-level security enforced on every query. Every enforcement decision is logged with full audit context. Role-based access means finance sees chargeback reports, not API keys.
SOC2 Type II in progress. Security architecture available on request.
