The cost and revenue of each service, measured — never rounded.
Commitment made on 2026-08-22 (decision): publish a lifetime-cumulative cost/revenue ratio for every E3 service sold, gated on the ledger's own verifiability alone — never on how the number looks. A service with no data renders honest gray, never zero; a service not yet wired for sale is shown as such, not as "€0".
The 5 E3 services
| Service | Sale status | Revenue |
|---|---|---|
aiame-red |
offered_sandbox_only | gray — no real revenue exists yet (no production payment key has ever been configured, for any AIAME service) |
aiame-sov |
offered_sandbox_only | gray — same reason |
aiame-auth |
not_offered | not yet wired for sale |
aiame-optaplanner |
not_offered | not yet wired for sale |
aiame-fin |
not_offered | not yet wired for sale |
How to read this table
Three possible states, never a blank. not_offered: no offer exists in the catalog — different from "€0", confusing the two would already be a small dishonesty. gray: measurable in principle, nothing to measure today, with the reason written out in plain language. A third state, measured, appears the day a real order (not sandbox) exists for a service — none is today.
The founder's time is excluded from this calculation, explicitly — no measurement source exists for it yet, and omitting it silently would have been simpler but less honest.
The ledger itself (source code) traces every figure back down to a supporting document — no displayed amount can exist without a verifiable derivation path. This page is a hand-regenerated snapshot (no cron updates it); its freshness is verified by a mutation-tested guardrail (ADR-LEDGER-003) rather than simply promised.
