Spread the cost
A third when you sign, a third at the end of week two, and the final third once your product is built and ready to go live, so your cash flow can breathe.
Go-to-market plan and campaigns
£5,000 + VATA brilliant product is only half the story. Our marketing team will build you a three-month launch plan and campaign, so the right people find you from launch day.
Hosting and maintenance
From £50 per monthKeep your product speedy, secure and up to date once it’s live. We’ll look after hosting, updates and small fixes, so you can focus on your customers.
Your launch date is in the contract. If we miss it for reasons on our side, we keep working at no extra cost until it's done.
Your big idea, with a brilliant team wrapped around it
Velocity is a four-week, fixed-price MVP development service for non-technical founders, from Hiyield, a B Corp certified digital product studio.
An MVP (minimum viable product) is the first version of your product, with just enough features for real customers to use, love and pay for.
AI tools make it super easy to knock up a demo, and that’s ace! Turning it into something people trust, pay for and keep coming back to is the tricky bit. That’s the bit we love, especially when it’s for founders who want to make the world a better place.
Avoid the pitfalls before you hit them
Our senior team has taken over 150 projects from idea to launch. Nothing’s offshored, so you get everything we’ve learned along the way.
Give your customers something they can trust
Security, reliability, accessibility and data protection are baked in from the very start by our Cyber Essentials certified team. Your first customers can sign up feeling safe.
A whole team in your corner
Strategy, design, development and marketing experts work side by side on your idea, and they bring you in on every decision that matters.
Stay in the driving seat
No confusing jargon and no guesswork. We’ll talk you through every choice in plain English, so you always know what’s happening and why.
A product that’s kinder to the planet
As a certified B Corp, we make clean, lean, efficient products that are low-carbon by design, and you’ll get a carbon report for your product too.
Find your first customers
Add our go-to-market package and our marketing team will help you plan a proper launch, so your product doesn’t just go live; it gets loved.
Which route is right for your MVP?
There’s no single right answer, and that’s totally fine! It all depends on where you are now and what you need next.
