09FAQ
Questions, answered.
What happens in an AI app rescue audit?
Placeholder answer (partners to confirm). We review the code, security, data access and deployment, then hand you a written report with a prioritised fix list.
Who owns the code and designs?
Placeholder answer (partners to confirm). You do. Once invoices are paid, the code, designs and accounts are transferred to you.
Will you sign an NDA?
Placeholder answer (partners to confirm). Yes, we're happy to sign your NDA before you share anything sensitive.
Do you support the product after launch?
Placeholder answer (partners to confirm). Yes, through a support retainer covering fixes, updates and monitoring.
How do you price projects?
Placeholder answer (partners to confirm). Fixed scope, monthly retainer, dedicated team or hourly. We recommend one after the discovery call.
How does a project with you work?
Placeholder answer (partners to confirm). Discovery call, written scope and estimate, then short sprints with a demo at the end of each. You see working software early and often.
