Choose the Right Engagement Model

Staff Augmentation

Need a couple of extra engineers on your team?

Get senior mobile developers who join your internal team. They work your hours, join your standups and follow your workflows, just like any full-time mobile developer.

Dedicated Team

Need a few teams to deliver several products at once?

Get a self-managed team of engineers, QA and a tech lead dedicated to your roadmap. Ship several products in parallel without stretching your in-house staff.

Project outsourcing

Want to hand over the whole project, from scope to launch?

We own delivery end to end: discovery, architecture, build, testing and launch, with fixed milestones and regular demos so you always see progress.

You Ask We Answer

Frequently Asked Questions

How long does a typical implementation take?
-
Most engagements move from kickoff to a working first release in six to ten weeks, depending on scope and how much discovery is needed up front. We give you a realistic range after the first conversation rather than an optimistic one.
What level of support can our team expect?
+
We provide comprehensive, high-touch onboarding and 24/7 dedicated support. During the first 30 days, a dedicated success manager will guide your team through setup, custom integrations, and workflow training to ensure seamless adoption.
Can we integrate this with our existing software stack?
+
Yes. We work with the tools you already run — CRMs, data warehouses, payment providers, internal APIs — and map the integration surface during discovery so there are no surprises later.
Is there a limit to the number of active users?
+
No. What we build is yours, and it scales with your business. We size the infrastructure to your expected load and leave you with the documentation to grow it further.
How do you handle data security and regional compliance?
+
Security review is part of every engagement, not an add-on. We handle data residency, encryption at rest and in transit, access control, and audit logging, and we work to the compliance regime your industry requires.
Can we change or cancel our plan at any time?
+
Yes. Engagements run in monthly cycles, and you can change scope or stop at the end of any cycle. We hand over code, credentials, and documentation either way.
Do you offer custom training sessions for larger teams?
+
We do. Handover usually includes live sessions for your engineers and a recorded walkthrough your team can come back to, tailored to the parts of the system they will own.
