MarginPing watches your AI cost per customer and pings you the second an account costs more than it pays. The damage is usually 2–3 customers — meet them today, not on the invoice.
Helicone and Langfuse show total spend. That won’t tell you Northwind is bleeding you. MarginPing shows cost per customer against what they pay — and pings you the second one flips.
Upload an LLM usage export (or connect a provider read-only) and type your plan prices — no Stripe or billing access. Nothing sensitive leaves your side. Stripe stays optional, for later.
It matches cost to revenue and ranks every account by its real gross margin — updated live, so you never build another spreadsheet.
When a customer starts costing more than they pay, you get a Slack or email alert that names the account — so you catch it on the 3rd, not the 31st.
One caught leak pays for it — an upside-down account bleeds ~$43/mo, every month, until you find it. Both plans start with a free Margin Teardown.
Drop your email — send a usage export and we’ll show you exactly where the margin’s going.
