Why develop an MVP
Validate your idea. Wow investors before you scale
MVP development for startups is the process of building a rapid prototype of your product, with the most basic features. Then the MVP is tested in the market to get feedback from users. In B2B SaaS, getting initial validation for your idea is crucial - the stakes are high for your business buyers.
Quick and low-cost validation for your product idea
Attract early funding
Learn what real users think about your SaaS
Get Insights on the potential next stages of your product
Why UX-first MVPs
Get Higher Adoption from Day One with UX-first
When MVP software development is done with a UX-first approach, you get a product that is less work down the line and delights your users from day one.
Building with AI?
We also design and build AI-powered MVPs from LLM integrations to custom model pipelines. Same 6–8 week sprint framework.

Our MVP development process
Build your MVP in 8 weeks
01. Research & Strategy
First, we'll discuss your target users, the key pain point you solve, your value proposition, and the feasibility.
Week 1-2
02. Planning & Design
Let's separate the must-haves, should-haves, and could-haves of the features you want to offer.
Then let's visualise the product with Information Architecture, wireframing, and prototyping.
Week 2-3
03. Development
Next, we'll build the core functionality with back-end APIs and the front-end UI. You now have a prototype ready for deployment.
Week 3-7
04. Testing & Launch
Before launching, let's make sure there are no errors or bugs with QA testing. Then your product is ready to go out to the real world for the first time!
Week 7-8
05. Learn & Iterate
Once we gather analytics and insights from the initial users, let's assess effectiveness and plan for the next iteration.

MVP vs Prototype
MVP vs prototype: what's the difference?
Once sentence: “A prototype testes an idea. An MVP proves it with real users. Here's when you need each”
Click-through design, not functional
Tests UX and concepts
Days to build, lower cost
Real, working software
Real users, real data
6-8 weeks, investment-grade

Our MVP services
What type of MVP do you need?
We tailor our build to your product goal, whether you're launching something new, automating a workflow, or validating a dashboard concept.
New Product MVP
Have an idea and want to develop a product?
We'll take your idea, refine it, and build an MVP that is good to go in 8 weeks.
A new product MVP is a minimum-risk method to gain feedback and trial your idea to see if it has potential. It can also help you impress investors with the results you gather with your new product MVP.
Automation MVP
In a rush to get an MVP out quickly?
We can use automation to speed up your MPV development if time is of the essence. We use AI tools for some tasks, such as accelerated development, generating synthetic data for testing, and analysing feedback.
While we use AI tools, human judgment is never removed from automation MVP building. Artificial intelligence is simply a way to speed up processes without compromising on quality.
Dashboard MVP
Just looking to test out your ideas or gather evidence that it is working?
We can develop a data visualization tool to validate core product concepts, gather feedback, and prove value.
Dashboard MVPs are a great way to learn quickly and incorporate learnings into later iterations of the product.

FAQs
Answering your MVP software development questions
What's the difference between an MVP and a prototype?
A prototype is a clickable design used to test an idea, and it looks like a product but has no working code behind it. An MVP (minimum viable product) is real, functioning software that actual users can sign up for, interact with, and give you data from. A prototype answers "does this make sense?" An MVP answers "will people use this and pay for it?" Most of our clients start with a short prototype sprint to validate the UX concept, then move straight into the MVP build.
How much does MVP development cost in the UK?
Most UK MVP projects fall between £10,000 and £80,000 depending on complexity, feature scope, and whether the product includes mobile, AI, or third-party integrations. A lean MVP with a single core workflow typically starts at £10,000–£30,000. A full investor-ready product with auth, dashboard, and integrations is usually £30,000–£60,000. Complex builds involving AI features or multi-platform delivery can exceed £60,000. We give a detailed cost estimate in our first scoping call and no obligation.
How long does it take to build an MVP?
Most MVPs we build ship within 6 - 8 weeks from the start of the project. The first 1 - 2 weeks cover discovery and UX design, weeks 2 - 7 are the build, and the final week is testing, QA, and launch preparation. More complex products with AI features or multiple platforms can take 10 - 12 weeks. We work in focused sprints so you're seeing real progress, not waiting months to see anything. If speed is critical, we can discuss what's achievable in your specific timeline in the scoping call.
How do I know the 'minimum' that will work?
We can help you define the core problem your software needs to solve and prioritise features using the MoSCoW method (Must have, Should have, Could have, Won't have).
Why do investors want to see an MVP?
They like products that have a clear solution for a problem, proven market demand, and numbers and feedback to validate potential. An MVP is the easiest way to demonstrate these.
Do you support MVPs designed for investor pitches?
Yes - we specialize in building investor-ready MVPs that showcase traction, usability, and product potential. Our designs focus on clear user flows, measurable outcomes, and visual polish to help you impress early-stage investors.
Can you build an AI-powered MVP?
Yes. AI-powered MVPs are one of our fastest-growing service areas. We build products that integrate large language models (LLMs), custom AI pipelines, intelligent automation, and AI-assisted features into working MVPs. We use the same 6-8 week sprint framework, scoped around the AI capabilities your product actually needs, not a bloated feature list. If you're building with OpenAI, Anthropic, or custom models, we can scope what's viable and deliverable within your timeline and budget.
Can you help validate product-market fit during MVP development?
Absolutely. Our MVP process includes early-stage market research, user interviews, and live feedback loops to ensure your product aligns with real customer needs. We prioritize features that deliver the most value from day one.
Do you offer post-launch support after MVP delivery?
Yes. We offer flexible support packages for bug fixes, minor updates, performance monitoring, and scaling the MVP into a full product. Our goal is to be your long-term development partner, not just a launch vendor.
