What we build
MVP Development Services
01
Rapid Prototyping
Interactive Figma prototypes delivered in 1-2 weeks that simulate your core user experience. Cheap to change, and it catches confusing flows before anyone writes code.
02
Market Validation
Data-driven validation through user testing, analytics integration, and feedback loops. We integrate Mixpanel and Firebase Analytics from day one to track the metrics that matter: activation rate, retention, and feature adoption.
03
Lean MVP Development
Core-feature MVPs built with Flutter and Firebase. Most take about 6–12 weeks depending on scope; you get a timeline after the brief. We build the one job the product must do well, plus only what that job needs, prioritized with RICE scoring.
04
Scalable Architecture
A foundation you keep: Firebase and Cloud Functions scale with usage, and modular code with clean separation of concerns lets the MVP grow into the full product instead of being thrown away.
05
Investor-Ready Demos
Polished demo builds with analytics dashboards showing key metrics that investors care about: user growth, engagement, retention, and revenue.
06
Growth Strategy
Post-MVP growth planning including monetization strategy (subscription, freemium, or transaction-based), user acquisition channels, A/B testing framework, and technical roadmap for scaling. We integrate RevenueCat for subscription management and Stripe for payment processing.
How it works
Our process
Idea Validation & Scoping
We workshop your business hypothesis, identify the core value proposition, prioritize MVP features using RICE scoring, and define success metrics to validate product-market fit.
Rapid Prototyping
Interactive Figma prototypes that simulate the core user flow, allowing you to test with potential customers and gather feedback before writing a single line of code.
Sprint-Based Development
Two-week agile sprints building core features with Flutter and Firebase. Each sprint delivers a working increment that you can demo to users and investors.
User Testing & Iteration
Real user testing after each sprint with Mixpanel analytics tracking engagement, retention, and feature adoption. We iterate based on data rather than assumptions.
Launch & Distribution
We handle App Store and Play Store submissions, set up TestFlight and beta channels for early adopters, configure crash reporting and analytics, and prepare investor-ready demos.
Growth Strategy & Scaling
Post-launch support with weekly analytics reviews, A/B testing of key features, infrastructure scaling, and roadmap planning for the transition from MVP to full product.
Scoping
What goes in an MVP, and what waits
The checklist we use when scoping a brief. If a feature doesn't help a first user finish the core job, or help you learn whether they want to, it waits.
Build now
- Sign-in (email, Apple and Google) and a basic profile
- The one core workflow, end to end, on the platform your users actually use
- The data model behind that workflow, with security rules from day one
- Analytics events on every step of the core workflow, plus crash reporting
- Payments, only if charging is part of what you are testing
- A feedback channel: in-app form, email or chat
Cut or fake for now
- Admin dashboards: use the Firebase console or a spreadsheet export at first
- Roles, teams and granular permissions
- A second platform, if one platform can prove the idea
- Multiple languages, themes and heavy custom animation
- Offline mode and complex sync
- Integrations that a manual step can stand in for during the first months

Questions
Frequently asked questions
What is an MVP in app development?
A minimum viable product is the smallest version of your app that real users can use for the core job, built so you learn whether they want it before paying for everything else. Eric Ries popularized the term in The Lean Startup. In practice that means one core workflow, sign-in, the data it needs, analytics, and a way to collect feedback.
How much does MVP development cost?
It depends on the core workflow, the number of screens, integrations such as payments, and whether you need an admin panel. Our free app cost calculator gives a range for an MVP-sized scope with every assumption listed, and after the brief we send a fixed quote by milestone.
How long does it take to build an MVP?
Most MVPs take about 6–12 weeks depending on scope; you get a timeline after the brief. The biggest lever is scope: every integration, role or admin screen adds time, so the brief decides what waits for version two.
Which features should an MVP include?
Sign-in, the one core workflow, the data model behind it, basic settings, analytics events on each step of the core workflow, crash reporting, and a feedback channel. Payments only if charging is part of what you are testing. Admin dashboards, roles and permissions, multiple languages, offline mode and deep integrations usually wait.
When should I scale beyond the MVP?
When the numbers you set before launch say people keep coming back: retention that holds week over week, users asking for more, and ideally someone paying. Until then, spend on learning, not on features.
Why hire MVP developers instead of using no-code?
No-code is fine for testing demand with a landing page or a simple internal tool. A custom MVP makes sense when the core job needs native device features, real-time data, payments or logic a no-code tool can't express, or when you want a codebase that grows into the full product. Our custom vs no-code comparison covers the trade-offs.
Fixed-price services
Prefer a fixed price?
Fixed scope, fixed price, paid upfront. The work happens in writing; no call needed.
