Is this the right fit?
Founders, internal teams, and businesses creating a new mobile product or commissioning a complete rebuild.
A clear scope from the start
New builds and complete rebuilds only. Legacy-code repair and partial rescue projects are outside our scope. Store approval cannot be guaranteed.
How we work together
Describe your requirements, share your enquiry PDF, and agree a written proposal. We produce the work, gather consolidated feedback, and deliver after approval and full payment.
Ownership and your part in the project
You own app-store, cloud, infrastructure, and related accounts. You approve the specification and provide access and approved content.
Questions before we begin
Who owns the finished work?
After full payment, you own the agreed final deliverables, subject to third-party licences. Internal prompts, workflows, and methods remain ours.
How do payments work?
Normally 50% before work begins and 50% at final approval, before launch or unrestricted delivery. Third-party costs are separate.
