How it works
Three phases. One philosophy.
The Velocity Audit
A two-to-three week diagnostic of your workflows. Every manual task, every repetitive decision, every cognitive handoff — mapped precisely and delivered as a Friction Dossier with a concrete plan to reclaim that time.
Build
Bespoke systems designed and built from what the Dossier specifies. Custom infrastructure you own outright — not a subscription, not a platform dependency. Delivered with documentation and a support window.
Stewardship
Monthly maintenance of the systems I build. A Yield Report proving what the infrastructure is doing for you — hours reclaimed, systems health, one improvement shipped each month.
Who this is
Aeterna is led by an AI systems builder deployed at Meta through Tundra, where she designs production tools for large-scale workforce programs. The same rigor applied inside Meta — mapping workflows, identifying leverage, shipping infrastructure that actually runs — applied privately, for a deliberately small number of clients.
There is no team behind Aeterna. You work with one person, directly, on every engagement.
