Frequently Asked
Questions
Most startup MVPs across the agencies compared here range from $12K–$45K depending on platform scope (single vs. cross-platform), backend complexity and whether design is included. Fixed-scope quotes are more common below $30K; above that, agencies typically shift to time-and-materials.
Pre-seed teams validating an idea often start with a freelancer or small studio for speed and cost. Funded startups building a defensible product typically move to an agency with a dedicated team model, then transition to in-house hiring once product-market fit is established and iteration speed becomes the bottleneck.
Ask who owns the source code and IP post-payment, what the post-launch support window covers, whether the quoted team is dedicated or shared across projects, and for two references from startups at a similar funding stage.
Cross-platform frameworks like Flutter or React Native cover most startup MVPs at lower cost and faster timelines. Native is worth the premium only when the app depends on platform-specific performance (AR, heavy background processing, hardware access). No-code fits pure validation before any development spend.
