How this compares to a £20,000+ agency build
| Route | Cost | Time | What that means |
|---|---|---|---|
| Traditional agency | £20,000 – £100,000+ | Months, before anything works | Discovery, design and development are quoted and paid for up front, and the first thing you can actually use arrives near the end. |
| Freelance developer | Quoted against your spec | Depends entirely on the spec | Usually cheaper than an agency, but it needs a detailed specification you probably do not have yet, and writing that is its own project. |
| A Bluprint Prototype Sprint | From £750 | 5 working days | The whole idea, fully working and testable, before you commit to either of the above. |
Frequently asked questions
How long does a prototype take to build?
Most prototypes are delivered within 5 working days of our initial define session. Complex projects may take slightly longer, and we'll always be upfront about timelines.
Is this just wireframes or mockups?
Neither. Every Bluprint prototype is fully working: your team can test every feature, every flow, and every interaction as if it's already live. This is not a demo.
What happens after the prototype?
That's up to you. You can take it to your own development team, we can introduce you to a trusted development partner, or we can stay involved and manage the build for you. We have options to suit every situation.
Do you work outside Northern Ireland?
Yes. We're based in Northern Ireland but work with businesses across the UK, Ireland and worldwide. Everything can be managed remotely.
How much does a Bluprint prototype cost?
The Prototype Sprint starts from £750 and delivers a fully working digital product in five working days. For more complex builds involving multiple user types, integrations, or AI features, we'll scope it with you before anything is agreed. There are no hidden costs and no surprise invoices.
Do I need a technical background to work with Bluprint?
Not at all. Most of our clients are business owners, founders, and team leaders who have a clear idea of the problem they want to solve but no technical expertise. That's exactly who we built Bluprint for. You bring the idea. We handle everything else.
What do I need to have ready before I get started?
Just a problem worth solving. You don't need a spec document, wireframes, or a technical brief. When you talk to Blu, our AI intake agent, it'll ask you the right questions to build a clear picture of what you need. Most briefs are ready within 24 hours of that first conversation.
How is Bluprint different from hiring a developer or a traditional agency?
A traditional agency will typically quote you months of discovery, design, and development before anything is built, often at a cost of £20,000 to £100,000+. A freelance developer will need a detailed spec you probably don't have yet. Bluprint is designed specifically for the stage before that: getting something real in your hands fast, at a fraction of the cost, so you can test whether the idea is worth the bigger investment.
Who owns the prototype when it's finished?
You do. Everything Bluprint builds for you is yours from day one: the code, the design, the data. There are no licensing fees, no lock-in, and no dependency on Bluprint to keep it running. You can hand it to any developer or agency to continue building.
What kinds of ideas work best with Bluprint?
We work best with ideas that have a clear user and a clear problem. Customer-facing apps, internal business tools, booking systems, AI-powered workflows, voice agents, data dashboards. If it's a digital product that solves a real problem, we can prototype it. The one thing we're not suited for is hardware or physical products.
How does the voice intake with Blu work?
Blu is Bluprint's AI intake agent. Instead of filling in a form or writing a brief, you have a short conversation, usually five to ten minutes, where Blu asks you about your idea, your users, your timeline, and your budget. From that conversation, it generates a structured brief that our team reviews and refines before work begins. It's faster, more natural, and produces better briefs than any form we've ever tried.
