Software development in Cornwall
Why choose a software development agency in Cornwall?
What working with us gets you:
- Local team, high standards – a partner you can sit down with in Truro, building to the standards you’d expect from any big-city agency.
- Software that fits your organisation – custom software development shaped around how you work, not the other way round.
- The right tech, chosen carefully – modern tools picked because they suit your project and will still make sense in five years.
- Honest pricing – clear scoping and no surprise invoices. You’ll always know what you’re paying for and why.
- A partner beyond launch – ongoing support and retainers for continual improvement, so your software keeps pace with your ideas.
We’re really pleased with how the site turned out. We’re already seeing the impact of Hiyield’s work — we saw almost 4.5x more clicks and 67x more impressions from our site within a month. So far, we’ve only indexed 17% of our site’s pages, so we are expecting those numbers to still increase.

See our work in action
When The Wave – the UK’s first inland surf destination – launched their new glamping venture, they needed a microsite and a booking system built from scratch. We designed the whole journey around the user, making it effortless to explore the tents and book a stay.
The result? A bespoke booking system that took The Camp at The Wave from zero to thousands of users a month.
Our approach
Great software isn’t just about the code. Here’s what you also get with us:
- An agile way of working – short sprints and room to adapt as your needs become clearer
- Regular updates, no jargon – you’ll always know where your project’s at and what’s coming next
- User experience front and centre – we build software people find genuinely easy to use
A climate-conscious software development agency
As a certified B Corp, sustainability isn’t a side project for us – it’s built into how we work. Efficient code, lower-carbon hosting and clean design mean the software we make is kinder to the planet, and usually faster and cheaper to run too.
We measure the carbon impact of every project and offset it through tree planting and rewilding, so the things we build for you leave a lighter footprint from day one.

Questions? We’ve got answers!
What makes Hiyield different?
We’re a Cornwall software development company that pairs local, in-person collaboration with the standards you’d expect from any big-city agency – plus a genuine commitment to building sustainably. And as a B Corp, we’re held to account on it.
Can you handle complex, large-scale software projects?
Yes. We’ve built everything from bespoke booking systems for popular tourist attractions to the Hub of Hope – the UK’s largest mental health support finder, used as a signposting tool by the NHS and government. We’re comfortable with scale and complexity.
How long does custom software take to build?
It depends on what you’re building – a focused tool might take a few weeks, a complex platform several months. Book a call, and we’ll give you an honest estimate based on your actual project.
How much does custom software cost?
Every project’s priced on what it needs – features, complexity and scale all play a part. Our custom builds typically start from ÂŁ10,000. Book a call and we’ll give you a clear, honest quote for your specific requirements.
Do you offer ongoing support after launch?
We do. Most clients stay with us on a retainer for support, improvements and new ideas – because good software keeps evolving as your organisation grows.
