Who Can Build Your MVP for a Fixed Price? 5 Agencies Compared
31 Aug 2026
Building an MVP is supposed to reduce startup risk. Yet the way software development is often purchased can introduce a different kind of uncertainty: an open-ended development budget.
An estimate of 500 or 700 development hours may help with planning, but it still leaves founders exposed if the project takes longer than expected. Fixed-price MVP development takes a different approach. Instead of buying engineering hours, the startup agrees on a defined scope, timeline, and price before the main development work begins.
For founders who value budget predictability, this can make planning an MVP considerably easier. Below, we compare five agencies offering fixed-price MVP development and explain when this model makes sense compared with more flexible approaches such as time and materials.
What Does Fixed-Price MVP Development Actually Mean?
In a fixed-price engagement, the agency and client agree on what will be delivered and how much it will cost before development begins. The agreement will typically define the core functionality, platforms, integrations, timeline, deliverables, and total project price.
This is different from time and materials (T&M), where the client pays according to the number of hours or days the development team works.
Importantly, choosing fixed price does not necessarily mean arriving with a complete technical specification. Some MVP agencies help founders turn an early product idea into a realistic first-release scope before locking the price.
That scoping stage is critical. A good fixed-price MVP is not simply a large software project squeezed into a predetermined budget. It is a deliberately limited first version designed to test the product's most important assumptions.
5 Fixed-Price MVP Development Agencies to Consider
There are many companies offering MVP development, so this is not intended as an exhaustive ranking. Instead, we selected five providers worth considering that represent different budgets, specializations, and approaches to fixed-price development.
Asper Brothers
Fixed price: $10,000
Typical timeline: 4–6 weeks
Best for: Early-stage founders
Website: asperbrothers.com
Asper Brothers offers a particularly straightforward model: a full MVP package for a fixed price of $10,000, typically delivered within 4–6 weeks. The company works with founders from the idea stage, helping define the MVP scope before moving through design, development, and deployment. This makes the offer particularly relevant for early-stage founders who want cost certainty but do not yet have a complete technical specification.
RaftLabs
Fixed price: $15,000–$35,000 for a Basic MVP
Typical timeline: 6–14 weeks
Best for: Technical and AI-enabled MVPs
Website: raftlabs.com
RaftLabs uses fixed-cost, milestone-based engagements, with Basic MVPs priced at $15,000–$35,000 and more advanced or AI-layered products at higher levels. The company locks the price once the scope is agreed, while additions become separately priced change requests. Its model can be a good fit for startups building products with greater technical complexity, integrations, or AI functionality.
Kinetico Agency
Fixed price: $15,000–$50,000
Typical timeline: 6–12 weeks
Best for: Funded startups wanting design and engineering from one team
Website: kinetico.agency
Kinetico Agency uses a tiered fixed-price structure ranging from $15,000 to $50,000. The final price depends on factors such as user roles, screens, workflows, and integrations rather than hours worked. Its model combines product design and engineering within the same team and is positioned primarily toward funded founders building a production-ready first version.
Inventiple
Typical fixed-price budget: $40,000–$70,000
Typical timeline: Around 8 weeks
Best for: Funded startups looking for senior-led engineering
Website: inventiple.com
Inventiple occupies the more premium end of this comparison. The company focuses on production startup MVPs built by senior engineers and states a typical fixed-price budget of $40,000–$70,000, with an average delivery time of around eight weeks. Its process includes discovery and scope lock-in before development, with architecture, engineering, deployment, and post-launch support forming part of the broader engagement.
The App Architect
Fixed price: From $18,000
Typical timeline: 2–4 weeks
Best for: Mobile-first MVPs
Website: theapparchitect.com
The App Architect specializes in mobile products and publishes an MVP starting price of $18,000, with delivery typically taking 2–4 weeks. The initial MVP package covers one platform — iPhone or Android — as well as the backend and database, store publication, and 30 days of post-launch bug fixing. The final binding quote fixes the price for the agreed scope before development begins
Fixed-Price MVP Agencies Compared
| Agency | Fixed Price | Timeline | Best For |
|---|---|---|---|
| Asper Brothers | $10,000 | 4–6 weeks | Early-stage founders |
| RaftLabs | $15k–$35k Basic | 6–14 weeks | Technical and AI MVPs |
| Kinetico Agency | $15k–$50k | 6–12 weeks | Funded startups |
| Inventiple | $40k–$70k typical | ~8 weeks | Senior-led development |
| The App Architect | From $18k | 2–4 weeks | Mobile-first MVPs |
Prices alone should not determine which agency is the best fit. The scope included in the price, technical complexity, platform, level of product support, and what happens after launch can be just as important as the headline number.
Why Choose a Fixed-Price Agency for Your MVP?
You Know Your Development Budget Upfront
For an early-stage company, predictability can be extremely valuable. Development is rarely the only expense associated with launching a startup. Founders may also need budget for marketing, customer acquisition, legal work, infrastructure, sales, and further product development.
Knowing that the first version will cost a defined amount makes it easier to allocate the remaining runway.
Instead of asking, “How many development hours will this take?”, the more useful question becomes: “How much will it cost to get this version of the product launched?”
The Agency Takes More Estimation Risk
With time and materials, additional development time generally means additional cost for the client.
A properly structured fixed-price engagement shifts more of the estimation risk toward the agency. If the vendor underestimates how much work is required to deliver the agreed scope, the startup should not automatically receive a larger invoice.
That creates an incentive for the development partner to understand the product, estimate carefully, and define the boundaries of the engagement before coding begins.
It is also why founders should pay close attention to how an agency handles scope changes. Fixed price should apply to the agreed scope; genuinely new functionality can reasonably require a new estimate.
Fixed Pricing Encourages MVP Prioritization
One of the biggest risks when building an MVP is turning it into a full product before anyone has validated the core idea.
A defined budget and scope force difficult but useful decisions. Which workflow actually demonstrates the product's value? Which features are essential for launch? Which integrations can wait until users prove they need them?
This constraint can be beneficial. The objective of an MVP is not to include every feature on the long-term roadmap. It is to build enough of the right product to learn from real users.
You Can Compare Outcomes Instead of Hourly Rates
Hourly rates can be misleading when comparing agencies.
A team charging $60 per hour but requiring 1,000 hours is not necessarily less expensive than a team charging a higher rate and completing the same outcome much faster.
Fixed-price proposals allow founders to compare vendors around a more useful unit: the deliverable.
What will be launched? When will it be ready? What is included? Who owns the code? And what will the total agreed investment be?
Fixed Price vs. Time and Materials for an MVP
Neither pricing model is automatically right for every software project.
Fixed price optimizes for predictability. Time and materials optimizes for flexibility.
With fixed price, the startup knows the expected cost and deliverables before committing to the build. The trade-off is that significant changes during development may require a new estimate or change request.
Time and materials provides greater freedom to change direction continuously. Features can be added, removed, or redesigned as the team learns. But because the client pays for the time consumed, the final development cost is inherently less certain.
For a clearly defined first release with a limited budget, fixed price can therefore be particularly attractive. For an existing product undergoing continuous experimentation, T&M may be more practical.
The two models can also be combined over a product's lifecycle: a startup might use fixed price to launch a clearly scoped MVP and move to a more flexible development model once real user feedback begins reshaping the roadmap.
What Should Be Included in a Fixed-Price MVP Proposal?
A fixed number on a proposal is not enough. The value of fixed pricing depends heavily on how clearly the underlying scope is defined.
Before signing, founders should understand what the agreement says about:
the core MVP features and user flows;
platforms and third-party integrations;
UX/UI design;
frontend and backend development;
testing and deployment;
project timeline and milestones;
payment structure;
source code and IP ownership;
post-launch support;
how scope changes are priced.
The clearer these points are, the easier it becomes to compare agencies and avoid disagreements later.
A useful rule is simple: fixed price works best when it is attached to a clearly defined outcome.
When Is Fixed Price the Right Choice for Your MVP?
Fixed-price MVP development is particularly worth considering when you have a defined budget ceiling, want to launch within a specific timeframe, understand the main problem your product needs to solve, and are willing to prioritize one focused first release rather than continuously expand the scope.
You do not necessarily need to know every feature before contacting an agency. In fact, product scoping can be one of the most valuable parts of the engagement.
What matters is that the startup and development partner eventually reach the same understanding of what version one needs to accomplish — and put that scope, timeline, and price in writing.
Final Thoughts
Choosing who should build your MVP is not only about comparing portfolios, technologies, or hourly development rates. The commercial model also determines how much financial uncertainty your startup accepts.
The right choice depends on your product, platform, scope, technical requirements, and available capital. But for founders working toward a clearly defined first release, fixed-price development offers an important advantage: it can turn software development from an open-ended expense into a planned investment with a defined outcome.
