FAQ

Frequently Asked Questions

What is included in an MVP?

An MVP includes core user flows, backend API, database, authentication, and the specific features that validate your business hypothesis. We scope the minimum feature set that lets real users test real value — nothing more, nothing less.

How long does an MVP take?

We target 4–8 weeks for most MVPs. Simple single-feature products can launch in 4 weeks. More complex multi-sided platforms or AI-heavy products typically take 6–8 weeks. We define the scope clearly up front so you know the timeline before we start.

Do you offer fixed pricing?

Yes. We agree the scope and fixed price before any work begins. No surprise invoices. If you want to expand scope mid-project, we discuss it as a change order with a clear price.

Can you add AI features to an MVP?

Yes — and we recommend it for most products. We can integrate GPT-4 or Claude for text generation, AI chatbots, smart search, recommendation engines, or any AI workflow relevant to your product.

What tech stack do you use for MVPs?

Next.js + React for web, React Native for mobile, Node.js for APIs, PostgreSQL for data, and Vercel or AWS for hosting. We use TypeScript throughout for maintainable, scalable code from day one.

Do you help with post-launch growth?

Yes. After launch, we offer ongoing development retainers for feature additions, performance improvements, and scaling. Many MVP clients stay with us as their products grow into full businesses.
