Partnering with Devzuno from the United States
How does Devzuno handle time zone differences for US website & app projects?
We provide dedicated 4 to 6 hours daily working overlap across Eastern Standard Time (EST) and Pacific Standard Time (PST). Our engineering leads participate in your daily standups, Slack channels, and weekly sprint demos during your standard business hours.
How fast can you build and launch a custom website or mobile app MVP?
A high-converting custom business website or landing page typically takes 2 to 4 weeks. A full-featured mobile app MVP (iOS & Android) typically ships within 6 to 10 weeks across agile milestone sprints with continuous demo builds.
How do IP ownership and NDAs work under US legal standards?
We execute comprehensive mutual Non-Disclosure Agreements (NDAs) before discussing project details. Upon milestone delivery, 100% full intellectual property (IP), source code repositories, and design assets are transferred directly to your company.
Why choose Devzuno over hiring high-cost US local agencies or unreliable freelancers?
US agencies often charge steep agency retainers with large overhead, while freelancer marketplaces suffer from high churn, missed deadlines, and inconsistent code. Devzuno offers structured milestone-based delivery, dedicated senior developers, and strict quality assurance at predictable rates.
What payment methods and currencies do you support for US clients?
We invoice cleanly in US Dollars (USD). Payments are accepted via US Bank Wire (ACH/SWIFT), Stripe (Credit/Debit cards), and Wise with proper corporate tax invoicing.
