How to Pick the Right Development Partner
Begin with a clear definition of your goals, target users, and budget. Review each agency's portfolio for projects similar in scope and industry. Ask how they handle discovery, design validation, and testing. Clarify ownership of source code and intellectual property in writing. Understand their communication cadence and project management tools. Finally, plan for life after launch; the best partners offer ongoing maintenance, analytics, and iterative improvements so your app continues to evolve with user needs.
Frequently Asked Questions
Should I build a native app or a cross-platform app?
Native development offers the best performance and access to device features, while cross-platform frameworks reduce cost and time to market. Many San Mateo startups launch cross-platform first and invest in native code once usage grows.
How long does it take to build an app?
A focused minimum viable product often takes a few months, while complex platforms with integrations, compliance requirements, and multiple user roles can take considerably longer. Clear scope is the biggest factor in keeping timelines predictable.
Who owns the code when working with an agency?
Reputable agencies transfer full ownership of source code and design assets to the client. Confirm this in your contract before work begins, along with access to repositories and cloud accounts.
