Case studies
What Reserver finds in real AWS accounts.
Every study here reads a real account end to end: its own reservation ledger, usage history, and fleet, priced at the rates it actually pays. All are anonymized at the customer's request. Fleets of every size, from a six-instance startup to an AWS Organizations footprint spanning dozens of accounts.

Real account40 AWS accounts, one blind spot: $250k/yr found
A real AWS Organizations footprint across 40 member accounts, the size where every account looks fine alone and the money hides in the seams between them. Priced at the accounts' own rates: an org-wide renewal lapse, coverage drift nobody could see whole, and reservations stranded by a re-org.

Real accountThe $2.4M account that did everything right, and still leaked $60k a year
A multi-region SaaS platform with twelve years of reservation discipline: 550 reservations bought since 2014, coverage most teams would envy. We read the whole ledger. The money leaked in the seams between manual reviews, and in a purchasing habit nobody ever re-derived from the data. Not ignorance.

Real accountSix instances, one missed renewal: $2,195 found
A real, lean, single-account fleet, the size a founder or a small platform team actually runs. Priced at the account's own AWS on-demand and Reserved Instance rates for the exact classes named, anonymized at the customer's request. A missed renewal and a never-reserved tier, both quantified.
