Cost audits for AI-built apps

Your app is making money.
It's also leaking it.

$0.0000

What a typical leaky AI-built app wastes while you read this page — retry loops, bloated prompts, unindexed queries, oversized servers. Illustrative, but uncomfortably realistic.

Apps built with Lovable, Bolt, Replit, and v0 are optimized to ship fast — not to run cheap. Plumb reads your real usage like a utility meter, finds every leak, and fixes it. Most audits pay for themselves in the first quarter.

An itemized bill of waste, from real AI-built apps

These aren't hypotheticals. They're the patterns builders report — and the ones we find in nearly every audit.

How a meter reading works

01 · Free, 10 min

Leak check

Connect your app and billing dashboards read-only. We flag the obvious leaks — exposed keys, retry patterns, prompt bloat — and estimate what they cost you per month.

02 · The audit

Full meter reading

A senior infrastructure engineer traces every dollar: AI tokens, database, hosting, third-party APIs. You get a line-by-line map of where money goes and which lines shouldn't exist.

03 · The fix

Leaks, plugged

We ship the fixes — caching, right-sizing, prompt trims, indexes, spend alerts — and set up a meter you can actually read, so the bill never surprises you again.

The Plumb guarantee: if our audit doesn't find annualized savings of at least the audit fee, the audit is free. We've never had to honor it — leaks are that common.
