Small apps for small teams.

Fifth Ace builds focused, private tools for libraries and small organizations. Each one does a single job clearly, and never asks for more data than it needs.

Ante

Small antes, not big blinds.

Short, plain-language security questionnaires your team can finish between meetings, plus a place to record incidents when they happen.

  • 18-question quick start
  • Import ready-made question sets
  • Keep a record of incidents

A preview of Ante: the quick-start questionnaire, here on question 3 of 18, asking whether everyone uses multi-factor authentication for work email, with answers Yes, No and Not sure, and an incident log that has nothing recorded yet.

Cardea

Count what matters. Nothing more.

Tap once when someone asks a question, in person or remote. Enter the gate count. Cardea turns it into charts and summaries, and never asks for patron information.

  • Tap-to-count questions
  • Gate counter entries
  • Charts and summaries, numbers only

CardeaPREVIEW

A preview of Cardea: today's reference desk with a tap button for questions asked in person and another for remote, a field to enter the gate count, and a note that no patron information is collected.

Private by design

Each app collects only what its job requires. Cardea never sees a patron's name.

Plain language

No jargon walls. If a question needs explaining, the explanation is right there.

Built small on purpose

One job per app, done well, so it's quick to learn and easy to trust.

Built in Fayetteville, Tennessee

Fifth Ace is run by William, who spent a decade in higher-education IT, from technician to CISO, before building the tools he wished he'd had.
