MVP Development Services | Fixed Price
Your prototype proved the idea. An MVP that ships to real users is a different build. A demo from Lovable or Replit and production software are not the same thing, and the gap between them is where most launches stall.
RaftLabs turns a working prototype or a rough MVP into software real users can trust. We assess what you built, keep what's validated, and rebuild what won't scale. 20+ MVPs shipped in 24 months across SaaS, AI, healthcare, and loyalty platforms.
Pause or exit at any milestone, you're never locked in
Fixed-cost MVP development, know your spend before you commit
Minimum 8 weeks ongoing support post-launch. So you don't break a sweat after go-live
MVP development services for startups and enterprises, same process, scoped to your stage

Key takeaways
Trusted by


Picture the version you actually want. Six weeks from now, real users are clicking through working software, not a deck. The data coming back tells you, in plain numbers, whether the thing you believed is true. You still have runway left to change course if it isn't, or to raise on it if it is.
Now the version most founders get instead. 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?
Three terms get used interchangeably by agencies, and mixing them up is what makes founders pay for the wrong one.
If you already know your users, have validated demand, and have funding, you don't need an MVP. You need full product development (custom software development). An MVP is for the moment before that, when the one assumption underneath the business is still unproven.
The odds today
The number didn't move between 2021 and 2024. That's not because founders got careless. It's because most MVPs are still scoped to impress, not to test.
Clinkle raised roughly $30 million in seed and early funding, reportedly the largest seed round in Silicon Valley history at the time, and spent over a year building in secrecy before launching a mobile payment product in 2014. The market it was betting on, replacing the cards and PayPal people already trusted, was never tested until the money was already spent and the team had scaled up around it. The company collapsed later that year and formally shut down in 2016. The lesson isn't that the team was untalented. It's that an enormous amount of capital and engineering time can go into making something real before anyone checks whether the one assumption underneath it is true.
If you're reading this, you've likely taken a run at one of these. None of them are foolish. Each one stalls in a predictable place.
The thread through all four: the build itself was never the hard part. Deciding what not to build is, and that's the part each of these skips.
Every RaftLabs MVP starts the same way: we agree, in writing, on the one assumption the build has to test. The extra screens, the "while we're at it" features, the nice-to-haves, all of it gets deferred to a backlog for after you have real data. This is the same discipline behind RaftLabs' four-step model: understand the problem, prototype it so you see it before you commit, build the MVP that tests it for real, then grow what works. The MVP is not a smaller version of the eventual product. It's the fastest, most honest way to find out if the eventual product should exist at all.
Key Insight
Walk us through the idea and the assumption it needs to test. We scope the build and give you a fixed cost.
Everything on the left should already be true. Even one thing on the right, and full product development is the smarter spend right now.
A first-time founder with a validated idea and limited runway to test one core assumption.
A seed-funded startup that needs investor-ready software with real usage data, not just a pitch deck.
An established business validating a new line of business before committing internal resources to a full build.
What we build
We cover the full build, from discovery and architecture to launch and post-launch iteration.
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. A design decision resolved here, on a static screen, is far cheaper to change than the same decision found in week 8, after it's already built into working software.
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.
Clients include Vodafone, T-Mobile, Aldi, Nike, Cisco, and Lockheed Martin, across AI, SaaS, mobile, automation, and enterprise platforms.

01 / 08
MVP vendors have earned their skeptics too. Before you get on a call, here are the objections we hear most, answered plainly.
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.
Scoped to the one assumption you're testing. Live in 6-14 weeks, with 8 weeks of post-launch support included. Start with the basic build and add the AI layer or a second platform once you've validated it.
A short scoping session turns your idea into a priced build plan. Start with the smallest version that tests your assumption, then grow it once you have real users.
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.
Price locked at scope
Once we scope your MVP, that price is locked in writing. A scope change is a priced change request, never a surprise on the final invoice.
The parts that decide whether an MVP produces a real answer, not just a shipped product.
The core assumption, the minimum feature set, and the architecture, documented in week 1. It's yours whether or not you build with us.
Everything that doesn't test the core assumption gets deferred to a backlog, on purpose, so the build stays fast and the answer stays clear.
Working software you can click through early, not a status update. Bi-weekly demos after that, so drift gets caught in week 3, not week 12.
Covering the riskiest window for any new product: the first two months after launch, when real usage finds what a demo never could.
The repository, the infrastructure, the third-party subscriptions, all in your accounts from the start. No handoff cliff, because there's nothing to hand off.
Milestone-based payment means you're never locked into the full engagement. If the data changes your mind, you can stop and keep everything built so far.
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.
An MVP rarely stands alone. Before the build, product discovery turns a rough idea into a scoped plan. If the idea is AI-first, AI MVP development designs the model work in from day one. And once the market signals are clear, custom software development takes the validated MVP to a full product.

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.
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).
Basic MVP development starts at $15,000, for a version with one or two core features, a simple design, and a clearly defined scope. A standard MVP with a full feature set, an AI layer, or multi-platform delivery runs $30,000 to $60,000. We provide fixed-cost proposals after a scoping session, not hourly estimates that shift as scope changes.
The timeframe depends on scope and complexity. At RaftLabs, our lean process is designed to launch your web, mobile, or AI MVP within 6-14 weeks. We scope only what's needed to test your core assumption, which is how we avoid the 6-18 month timelines common elsewhere.
You don't have to become technical to evaluate this correctly, you have to ask for the right artifact. Ask for the written scope document before any code is written: the one assumption being tested, the minimum feature set, and the technical architecture. A vendor that can produce this on day one, in writing, before invoicing anything, is one you can evaluate on paper regardless of your technical background. A vendor that can only offer a demo or a vague timeline is the tell. At RaftLabs, the scope document from our discovery phase is yours to keep, whether or not you build with us, precisely so you have something concrete to judge, compare, or hand to a technical advisor.
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 $15,000-$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 keeps your concept 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.
