Independent software studio · Est. 2019

Software, distilled.
Built quietly, used daily.

Retroage Engineering is a small studio building tools for people who care about the small things — native Mac apps, attribution infrastructure, and the unglamorous pieces that make a product feel inevitable.

02 — How we work

Four convictions, repeated daily.

01

Native, when it matters.

We use the platform on purpose. SwiftUI on the Mac, edge runtimes on the web. Frameworks come and go — the operating system is the product.

02

Privacy as posture.

We don't collect what we don't need, and we don't need much. No analytics SDKs, no third-party fingerprinting, no quiet exfiltration. Default off.

03

Small, sharp, shipped.

One feature, done right, beats five half-built. We trim until what's left carries weight. The work shows up in what we choose not to add.

04

Cost is a craft.

Free-tier first. We architect on the assumption that every tenth-of-a-cent compounds. Your unit economics are a design constraint, not an afterthought.

03 — The studio

A studio, not a startup.

Retroage is independent and intends to stay that way. We take on a small number of engagements each year — usually one part product, one part infrastructure, and one part “we're not sure who else to ask.”

We work best with founders who treat software as a long game: people building instruments, not features. If that sounds like you, we'd like to hear from you.
