About Sisnex
Sisnex LLC is a privately owned software company registered in the State of Wyoming. We build mobile applications for clients and publish our own.
What we believe
Good mobile software is fast, predictable and quiet. It works offline when it should, respects the battery and the user's data, and keeps working after the next OS update. We would rather ship fewer features that hold up than many that don't.
We keep our team small and senior on purpose. The person who scopes your project is the person who builds it.
Leadership
