Netflix started as a simple idea: let people stream video instead of renting discs. That idea grew into a platform used by hundreds of millions of people worldwide. Spotify did the same thing for music. Neither started as a finished product—they started as an idea someone decided to actually build. If you’ve got a concept for a streaming, subscription, or content platform, the gap between “idea” and “working app” is smaller than most people think—provided you build it the right way.
You don’t need to be technical. You don’t need a co-founder who codes. You need a partner who can turn your idea into real, working software without disappearing halfway through or charging you agency-sized invoices for a project that drags on for a year. That’s where By Design UK comes in.
Strip away the branding and a platform like Netflix is built from a handful of core components: user accounts and subscriptions, secure payment handling, a content or video library, a recommendation system, and an admin backend to manage everything. Whether you’re building a full streaming service, a niche subscription platform, or a content-led membership app, the underlying architecture follows the same proven pattern—it’s the scope and polish that scale with your budget.
Costs vary hugely depending on how ambitious your idea is. A focused first version—enough to test your concept with real users—typically starts around £18,000, while a fully-featured, scalable platform with custom video infrastructure, recommendation engines, and multi-device apps can run well beyond £650,000+. Our platform development service is priced fixed and scoped around what your idea actually needs, not a generic package. If your idea is closer to a content-driven online store or membership shop rather than a full streaming service, a Shopify-based build starting from £499 might get you to market faster and cheaper.
Freelancers are often affordable but risky—one person juggling multiple clients, disappearing mid-project, or leaving you with code only they understand. Traditional agencies swing the other way: slow timelines, opaque pricing that creeps upward, and a habit of retaining control over your own codebase. Neither model fits someone with a genuine idea and a realistic budget. By Design UK sits deliberately between the two: agency-level structure and reliability, freelancer-level speed and directness, with fixed pricing agreed upfront and full source code ownership handed to you—not licensed, not held hostage.
We also build faster than a traditional agency because we use AI-accelerated development throughout our process—for scaffolding, testing, and repetitive engineering work—so more of the budget goes into the parts of your platform that actually differentiate it.
We’re not a design studio pitching mockups. Tackly.co.uk is a live, multi-toolkit platform we built and continue to run ourselves—real users, real subscriptions, real infrastructure, built and maintained by our own team. It’s the clearest evidence of what we can deliver: a UK-based team that designs, builds, ships, and supports software under a fixed-price, full-ownership model, rather than disappearing after handover.
A streaming or subscription platform isn’t a one-off build—it needs monitoring, updates, and improvements as your user base grows. Our support plans start from £797/month for platform builds (or £299/month for Shopify-based stores), covering hosting oversight, bug fixes, and ongoing feature development so your platform keeps improving after day one.
Every project starts with a straightforward conversation about your idea, your budget, and what a realistic first version looks like. There’s no pitch deck theatre and no obligation. Learn more about how we work on our about page, or reach out directly via our contact page to talk through your idea with our team.
No. Most of our clients start with just an idea and no coding background. We handle the technical planning, design, and development, and explain everything in plain language throughout the process.
Yes. Unlike many agencies that retain rights or lock you into their infrastructure, By Design UK hands over full source code ownership once your project is delivered.
A first working version typically takes a few months depending on scope. Using AI-accelerated development, we’re often able to move faster than traditional agencies without cutting corners on quality.
That’s fine—many great platforms start focused and grow. We’ll help you define a realistic first version, whether that’s a full custom build or a Shopify-based solution if your idea is more product-led.
