Engineering Studio · California

We build the quiet software people keep for years.

Sunspire Tech US LIMITED is an engineering studio in City of Industry, California. We design, ship and operate consumer applications — reading, kitchen planning, listening — and we stay with them after launch.

01 / The Studio

Engineers first. Everything else follows.

Sunspire Tech US LIMITED is registered in the State of California and works out of City of Industry, east of Los Angeles. We are an engineering studio rather than an agency: we own what we build, we run it in production, and the same people who wrote a feature are the ones who answer for it when something breaks.

A spire is built one course at a time, and that is roughly how we work — narrow foundations, no shortcuts underneath, and height that comes from patience rather than from a launch campaign. It makes us slower at the start and considerably harder to knock over later.

We take on few products on purpose. Each one gets a real maintenance budget, a support address a person actually reads, and a roadmap measured in years rather than quarters.

02 / Practice

Four things we do, and nothing we don't.

01

Application Engineering

Native iOS and Android written by a small team that reads its own code six months later. Modest binaries, fast starts, and behaviour that does not change under a weak connection.

02

Interface Systems

Typography, motion and component libraries built once and reused across a product family, so a screen added in year three still looks like it belongs.

03

Platform & Operations

The unglamorous half: build pipelines, staged releases, crash triage, capacity planning and the on-call rotation that turns a launch into a service.

04

Store & Policy Readiness

Listings, age ratings, permissions review, data-handling disclosures and regional requirements — prepared before submission rather than argued afterwards.

03 / Work

A short catalogue, kept on purpose.

Sift

Reading

Follow the writers and publications you choose, in the order they were published, with no recommendation engine deciding what you meant to read.

Pantry

Kitchen Planning

Plan a week of meals, keep the recipes you actually cook, and walk into the shop with one list instead of five open tabs.

Verso

Listening

A player for long audio — lectures, audiobooks, interviews — that remembers where you stopped and never loses a chapter between devices.

04 / Contact

Write to us and a person replies.

Partnerships, publishing, press or a question about something we made — one address, read by the studio.
