Independent software studio

We build the whole stack and run it.

Run by two brothers. Design, code, infrastructure, and support all sit with the same two people, start to finish.

01 / About

Four products, one two-person team, no handoffs.

Zrionix Technology is a small, independent software studio built around two brothers who would rather run the stack than manage a vendor list. There is no dev agency in the middle and no outsourced support queue. The people who write the code are the people who get paged when it breaks. We build focused products, price them plainly, and keep shipping after launch day.

Pillar 01

Full-stack ownership

Schema, API, infrastructure, and the deploy pipeline: one team, no handoffs, no vendor telephone game.

Pillar 02

Published pricing

No revenue share and no surprise invoice once you scale, whether that's one flat rate or a few usage tiers.

Pillar 03

Privacy by default

We collect what a product needs to run and nothing else. Export or delete your data in one action.

Pillar 04

Ship, then iterate

Everything below is in active daily use. We maintain what we release: uptime, patches, and features included.

02 / Products

Two problems we know well.

Revenue recovery for subscription businesses, and a couple of focused apps for iPhone. No sprawling suite: four products, maintained on purpose.
