MVP development for startups, from $2,500
Turn your idea into a working product that real users can sign up to and use, built by an experienced team at a fixed price agreed before we start.
A minimum viable product (MVP) is the smallest version of your product that proves people want it. SixSol builds MVPs for founders in the United States, United Kingdom, Europe and the Middle East: web apps, mobile apps, AI-powered tools and connected devices. You get a live product in weeks, not a slide deck.
What you get for $2,500
- One core user journey, built end to end: the main thing your product does, working properly.
- A web app or a cross-platform mobile app: Next.js/React for web, or Flutter for iOS and Android.
- Sign-up and login, with user accounts and secure sessions.
- Backend, API and database, built to grow beyond the MVP.
- A simple admin panel to see users and manage content.
- One integration, such as Stripe payments, email or an AI model API.
- Launch on your domain, with the code in your own GitHub repository.
- 30 days of bug fixes after launch.
MVP scope and price
| MVP scope | Price |
|---|---|
| Lean MVP: one platform (web or mobile), one core user journey, login, admin and one integration | $2,500 fixed |
| Web and mobile apps together, or several user roles | Quoted after a free scoping call |
| AI MVP: chatbot on your documents, AI agent, document or image AI | Quoted after a free scoping call |
| Hardware or IoT MVP: device, firmware and companion app | Quoted after a free scoping call |
Every quote is a fixed price for an agreed scope, with payments split into milestones tied to working demos.
How we build your MVP in 4–6 weeks
- Week 1: scope and design. We agree the core journey, the screens and what success looks like, and show you a clickable design.
- Weeks 2–4: build. You see a working demo every week and can change priorities as you learn.
- Weeks 5–6: test and launch. We test on real devices, fix issues, deploy and hand over everything in your name.
Typical technology stack
Next.js and React, Flutter, Node.js and Python, PostgreSQL, Stripe, Firebase or Supabase where they fit, OpenAI and Anthropic APIs for AI features, and hosting on Vercel, AWS or Google Cloud.

We have shipped mobile apps, SaaS platforms, AI assistants and connected hardware for clients worldwide, so your MVP can grow into a full product without a rewrite. See our work, or read about our mobile app, backend and web app and AI agent services.
How much does it cost to develop an MVP?
A lean MVP with one platform and one core user journey costs $2,500 at SixSol, as a fixed price agreed before work starts. Products that need web and mobile apps, AI features or hardware are quoted after a free scoping call, so you know the full price up front.
How long does it take to develop an MVP?
A lean MVP usually takes 4–6 weeks: about one week for scope and design, three weeks of building with a demo every week, and a final week for testing and launch.
Which AI is best for building an MVP?
AI coding assistants speed up prototyping, but a product real users will pay for still needs proper architecture, security and testing. We use AI tools to move faster, and when your product itself needs AI we build on OpenAI, Anthropic Claude or Google Gemini APIs, choosing by cost, quality and data rules.
How do I choose a tech stack for a lean product launch?
Pick proven tools that let you change quickly and hire easily later. For most startups that means Next.js or React for web, Flutter for iOS and Android from one codebase, Node.js or Python for the backend and PostgreSQL for data. We recommend a stack in the first week and explain why.
Do I own the code?
Yes. The source code, cloud accounts, domain and app-store listings are set up in your name, and the code is handed over in your own GitHub repository.
What happens after the MVP launches?
You test with real users, then decide what to build next. We can continue in monthly sprints, help you add payments, analytics or AI features, or hand over to your own team with documentation.
