04 · About
Who you'll work with.
Aevori is led by Leon Franklin III, a full-stack and AI engineer in Detroit. He studied computer science at the University of Michigan and played football there, and the habits carried over: prepare the plan, run it the same way every time, review the film afterward.
Leon also worked on Chosn AI, a multi-agent orchestration system, so the AI work we do for clients comes from hands-on production experience.
The name comes from aevum, Latin for a lifetime or an age. It's the bar for every build: code you own outright, documentation the next developer can follow, and software that keeps working after we hand it over.

05 · FAQ
Questions, answered.
Get 20% off the project price for any new build booked by Thursday, November 26, 2026 at 11:59 p.m. ET. Booked means the proposal is accepted and the deposit is paid. The discount applies to every invoice for that project, including milestones billed after Thanksgiving.
50% deposit to book your start date, 50% at launch. Projects over $1,000 are split into milestones. Pay by card or bank transfer through Stripe; your payment details go straight to Stripe and never touch our servers.
You do. Code, accounts, and domains transfer to you when the final invoice is paid.
Every build ships with two weeks of fixes. When we work inside an existing codebase, anything we break along the way is fixed as part of the job. After that, pick a care plan of one month, three months, or longer for updates and monitoring, or hourly support when you need it.
Yes. We work remotely with clients anywhere and meet in person around Metro Detroit.
Usually within a week of the deposit. Your proposal lists the exact start date.
