Let’s talk

  • One team, end to end

    Design, engineering and QA work as one team in Mohali, so nothing gets lost between hand-offs. You talk directly to the people building your product.

  • Clear scope and budget

    Before any code is written we agree on the scope, deliverables and budget, and we tell you about any risk to the timeline as soon as we see it.

  • Working software every week

    You see a demo every week, not a big reveal at the end, so your feedback shapes the product while it is still cheap to change.

  • We stay after launch

    Launch is where most of our partnerships begin. We stay on for fixes, updates and new features, and keep the code documented so it is easy to hand over.

Callsy

Android app · CRM calling

Callsy connects a team’s phones to Zyvo CRM. Each handset is paired once; from then on, calls placed from the CRM ring on the agent’s phone, and every call is synced to the lead’s timeline automatically.

We built an Android app that pairs a handset to a Zyvo user with a QR code and listens for call commands. Calls dial on tap, or automatically when an agent claims a new lead, and each call syncs back to the lead. A fleet screen shows every handset’s live status.

Frequently asked questions

It depends on your requirements. Cross-platform (React Native) is cost-effective for most business apps. Native is preferred when platform-specific performance or deep hardware integration is critical.
