testimonials
What clients say
We've recently completed Phase 1 of a bespoke business valuation tool with James at Code23, and I've been extremely impressed. He has taken the time to understand both the commercial and technical requirements, communicated clearly throughout, and delivered a well-thought-out system with a high level of flexibility. The admin dashboard, in particular, gives us full control over the scoring and valuation logic, which was a key requirement. I'm looking forward to working with James on Phase 2 and would have no hesitation in recommending him to anyone looking for bespoke software development – Jason Atkins, Director, Lansley Commercial

Code23 undertook a large redevelopment project for us, including the rollout of over 100 individually branded websites. The overarching goals of the project were to improve: 1. Our Flexibility & Control 2. Customer Experience 3. Transparency Around Pricing All of which were delivered to an excellent standard, especially the new custom quote builder, which is industry leading! We look forward to continuing to develop these websites and build on the relationship with Code23 in future. Great work team!

James and his team are very talented, energetic and ambitious ... as much in supporting our business as in also developing their own. Very clever, very quick, on the front-foot, spot-on detail. No smoke nor mirrors, but straightforward and honest. We are delighted to have found them and very grateful for their help in making our new business flourish. Very, very, very highly recommended.

I have worked with Code23 and their team for over 5 years across 3 different projects ranging from mobile app development to custom WordPress websites. Together the team bring a level of expertise and professionalism I have not seen anywhere else... The results achieved have really helped to grow our business. I highly recommend their services to anyone looking for a custom project to be completed on time and in budget.

We have been working with James and the team at Code 23 for about 18 months now on a lengthy and sometimes complicated app development. At all times we have found Code 23 to be calm, competent, and their advice has been invaluable. The app is now live and we are extremely pleased with the results and are happy to continue our relationship with Code 23 for enhancements and hosting. We would be pleased to recommend Code 23.

Can't recommend these guys enough... really great service with expert advice. The technology they managed to integrate into our self service kiosk was outstanding and went the extra mile to make sure everything was as we wanted. Great job guys, i'll be engaging with Code23 for any future upgrades and add ons required TAN

Questions about SaaS & Platforms
What is a SaaS company?
A SaaS company delivers software on subscription rather than one-off licences. Building one means product, billing, admin and support paths from the first release - not just screens.
How much does SaaS development cost?
MVP cut, integrations and how much admin and billing you need in version one set the band. Blueprint defines the first release and we confirm current pricing against that agreed scope before Build begins.
How long does it take to build a SaaS MVP?
Blueprint locks the timeline against a defined MVP cut. Map and Blueprint come first so Build does not discover the product mid-sprint. Agents compress build; integrations usually set the critical path.
Do you build internal tools as well as customer-facing SaaS?
Yes. Business systems, portals and ops platforms are core work here - OI Group's Business OS replaced five SaaS tools and 30+ weekly admin hours.
Can agents really run SaaS operations after launch?
Yes, inside a clear remit. Agents handle onboarding nudges, support triage, usage outreach and billing recovery while seniors set policy and own risk - so the platform runs lean.
How much does a SaaS MVP cost in the UK?
UK SaaS MVP cost depends on the MVP cut, billing depth and integrations required in version one. Map and Blueprint define the first release, then current pricing is confirmed against that agreed scope before Build begins.
Can I hire a SaaS development agency for a UK startup?
Yes. Startups hire us for an honest MVP cut - paying users, billing edges and roles - scoped in Blueprint so you learn before surface area explodes. You work with the architects on the build; agents compress delivery so a small senior team ships like a larger one.
