The problem
MVP that took 8 months and $80K to build, tested the wrong assumption, and now needs a rebuild before you can raise the next round?
Development agency that built exactly what you specified, invoiced in full, and left you with a product real users do not use, because nobody asked the hard product questions before the build started?
Short answer
RaftLabs builds MVPs for startups and enterprise teams across the US, UK, Europe, Canada, GCC, South Africa, and Southeast Asia. Fixed price, 8-14 week delivery, milestone payments. 20+ products shipped in 24 months across SaaS, AI, and healthcare. 8 weeks of post-launch support included in every engagement.
Key takeaways
Trusted by


A founder spends eight months and $80K building the full product. Every feature they imagined a user might want is in there. It launches. Then the data comes in: the one assumption the whole thing rested on was never true, and now it needs a rebuild before the next round.
Nothing was wrong with the engineering. The scope was wrong, decided before anyone wrote a brief, with features added because they seemed useful rather than because they tested the right thing.
An MVP exists to answer one question before the budget is spent: does anyone actually want this?
Launching an MVP isn't the hard part. Building one that tests the right assumption, fast enough and solid enough to learn from, is where most builds fall apart. We start every engagement by agreeing on the one assumption the build must validate. Everything else waits.
According to CB Insights' analysis of failed VC-backed startups, 42% of startup failures are caused by building a product with no market need, not by poor execution or running out of money. An MVP exists specifically to answer that question before the budget is spent.

Everything on the left should already be true. Even one thing on the right, and full product development is the smarter spend right now.
What we build
We cover the full build, from discovery and architecture to launch and post-launch iteration.
Walk us through the idea and the assumption it needs to test. We scope the build and give you a fixed cost.
How it works
Every MVP follows four phases. Scope is locked and price is fixed before development starts.
We map the core assumption your MVP must validate, identify the minimum feature set, and define the technical architecture. You leave week 1 with a written scope document and a fixed-price quote. Nothing starts without your sign-off.
Wireframes and a clickable prototype before production code. Design decisions made here cost ten times less than the same decisions made in week 8. Founders who test at this stage typically save 20-30% of their development budget by resolving ambiguity early.
Working software at a staging URL by the end of sprint one. Bi-weekly demos. QA runs in parallel with every sprint. Auth, billing, API layer, and core feature logic all land in this phase.
Production deployment with monitoring activated on launch day. 8 weeks of post-launch support included in every engagement. The riskiest window for any new product is the first two months. You are not on your own during them.
What clients say
Three-year average engagement. Founders and operators describing the work in their own words. No marketing varnish.

Working with RaftLabs has been amazing. The team is super responsive and quick to address our needs. They built a booking platform that's been a game changer for our team and our guests.
01 / 08
We price by project, not by the hour. After a scoping session you get a fixed-cost proposal with a defined scope, timeline, and price, so you know the number before development starts. Where you land depends on scope, not negotiation:
What it costs
A defined scope, a timeline, and a price, agreed before development starts.
Fixed cost, by project not by the hour. 8-14 weeks to live. 8 weeks of post-launch support included.
We give you fixed-cost proposals after a scoping session, not hourly estimates that shift as scope changes. The number you approve is the number you pay.
Ownership
You own the code, the repository, and all third-party service accounts from day one. No platform lock-in, nothing stopping you from moving the work to an internal team or another agency.
Fixed price
Scope and price are locked in writing before development starts. A scope change is a priced change request, never a surprise on the final invoice.
The architecture changes with the domain. Compliance-heavy sectors need audit trails and access controls designed in from sprint one, while consumer platforms need the flow validated with real users before anything else. We build MVPs for:
FinTech and financial services: compliance controls, payment rails, and fraud logic scoped from the first sprint, not retrofitted after users go live.
Healthcare and life sciences: HIPAA-ready MVPs with PHI handling and audit trails built in before the first release.
Retail and e-commerce: storefront, checkout, and inventory MVPs that test demand before a full platform build.
Real estate and property: listing, management, and tenant-facing MVPs with the integrations that follow.
eLearning and EdTech: course, content, and engagement MVPs that validate the learning model before scale.
SaaS products: multi-tenant MVPs with billing and role management, built to scale without a rewrite.
AI MVP Development
AI-first MVPs with LLM integration, RAG pipelines, and intelligent workflows.
Web Application Development
Browser-based MVPs on React, Next.js, and Node.js.
Mobile App Development
Native and cross-platform MVPs for iOS and Android.
SaaS Application Development
Multi-tenant SaaS MVPs built to scale without a rewrite.
Product Discovery Phase
Structured discovery before committing to a full MVP build.
UI/UX Design
Wireframes and prototypes to test the flow before code.
Custom Software Development
Post-MVP product development and scaling.

Read moreA Minimum Viable Product (MVP) is the smallest version of your product that tests your core assumption with real users. It is production software that runs on real infrastructure, handles real users, and generates real data. At RaftLabs, every MVP engagement starts by defining the one assumption the build must validate - everything else is deferred to a later sprint.
The timeframe depends on scope and complexity. At RaftLabs, our lean process is designed to launch your web, mobile, or AI MVP within 8-14 weeks. We scope only what's needed to test your core assumption, which is how we avoid the 6-18 month timelines common elsewhere.
A prototype is a clickable simulation - it shows how a product looks and flows, but doesn't run on real infrastructure or handle real users. An MVP is production software that does. RaftLabs builds both. Which you need depends on your current goal: investor validation before committing to a build (prototype) or user validation with working software (MVP).
Our MVP development starts at $10,000 for a basic version with 1-2 core features, a simple design, and a clearly defined scope and timeline. More complex products with AI, multi-platform delivery, or advanced integrations run $25,000 to $75,000. We provide fixed-cost proposals after a scoping session, not hourly estimates that shift as scope changes.
For early-stage founders, MVP development needs to account for limited runway, fast iteration, and the need to prove a business model, not just ship features. Our startup-focused MVP development services include fixed-cost engagements, milestone-based payment, 8-week post-launch support, and scoping that forces the right decisions early. We've helped founders who came to us after spending $80K elsewhere with nothing to show for it.
The most common mistakes: building too many features before validating the core assumption, skipping real-user testing, starting development before the scope is defined in writing, and choosing a tech stack optimized for scale before you have a single paying user. RaftLabs runs a structured scoping session before every build specifically to surface and resolve these decisions before a line of code is written.
The MoSCoW method categorizes features by priority: Must Have (critical for the MVP to function), Should Have (important but not launch-blocking), Could Have (desirable but deferrable), and Won't Have (out of scope for this build). We use a version of this in every scoping session to separate what needs to be in the first release from what can wait.
Yes, with scope discipline. The two biggest cost levers are feature scope and technology choice. A Flutter cross-platform build costs significantly less than native iOS + Android. A well-scoped single-feature MVP at $10,000-$20,000 tests your core assumption faster than a $60,000 full-featured product. RaftLabs' scoping session identifies the minimum build that produces real answers - so budget goes toward validation, not features that may never matter.
An MVP is scoped to test one core assumption with the minimum features required. Full product development builds out the complete feature set. The right approach depends on your certainty. If you know your users, have validated demand, and have funding, full product development makes sense. If you're testing whether people want the product at all, start with the MVP. Most of our clients start with an MVP and move to full product development once the market signals are clear.
Yes, we sign an NDA before beginning any project to safeguard your idea. This ensures your concept remains confidential as we scope and build your MVP.
Frontend: React, Next.js, TypeScript, Tailwind CSS. Backend: Node.js, NestJS, PostgreSQL, Hasura, GraphQL. Mobile: Flutter for cross-platform, Swift for iOS, Kotlin for Android. AI: Python, AWS Bedrock, OpenAI, Anthropic APIs. Infrastructure: AWS, Firebase, Vercel. The stack for your project is chosen based on your users, your team, and what the product needs to do at scale.
Yes. You own the code, the repository, and all third-party service accounts from day one. There is no platform lock-in to RaftLabs infrastructure after launch. On the final day of the project, we transfer the codebase to your version control organization, all credentials to your accounts, and all subscriptions to your ownership.
A scope change is a change request: we scope it, price it, and add it only if you approve. It does not absorb into the project and appear on the final invoice. This is how we keep the price fixed. In practice, small clarifications that do not change the feature set are handled as part of the sprint. Changes that add new features or alter the architecture are priced separately before work begins.
Eight weeks of post-launch support is included in every project at no extra cost. This covers bug fixes for issues that emerge in production, performance tuning based on monitoring data, and minor UX adjustments from early user feedback. Support is via a dedicated Slack channel with a 4-hour response time during business hours and same-day response for production-down incidents.
Work with us
We scope MVP Development Services Company in 30 minutes. You walk away with a clear cost, timeline, and approach. No commitment required.
