Client FAQ

Frequently asked questions.

Everything you need to know about our sprints, pricing, tech stack, and post-launch support.

Most standard marketing websites and Shopify storefronts launch within 2 to 4 weeks. Custom FlutterFlow mobile/web apps, SaaS dashboards, or complex booking platforms typically take 4 to 8 weeks across structured weekly agile sprints.
We specialize in modern, high-velocity tech stacks: FlutterFlow & Flutter for iOS/Android native mobile apps, Next.js 14, React & Tailwind CSS for web apps, and Shopify Plus/Liquid for e-commerce. All user interfaces are crafted natively in Figma and backed by scalable cloud backends (Firebase, Supabase, Node.js).
Yes, absolutely. Upon project completion and final payment, you retain 100% full ownership of all source code, Figma design files, domain configurations, and assets. We never lock clients into proprietary systems.
All project builds come with a complimentary 30-day post-launch warranty to handle any refinements or bugs. We also offer ongoing monthly Growth Retainers covering maintenance, technical SEO, feature development, and ad campaign management.
We run asynchronous communication via Slack, WhatsApp, or email, supplemented by weekly live screen-share walkthroughs. You review real working prototypes every week, ensuring you are 100% aligned with progress.
