Up to 5x faster where implementation work compresses

For comparable AI agent implementation work, our senior team can move up to 5x faster than our own pre-agent baseline.

The multiplier applies to compressible build work such as code, tests and repeatable production tasks. Discovery, decisions, content and third-party waits still take the time they take.

“We're a property maintenance business, not a tech company. We came to Code23 with 30 years of industry knowledge, a head full of ideas and a spreadsheet-and-whiteboard operation, and asked them to turn it into a proper platform. A year on, our office runs on it daily: clients, contracts, jobs, quoting against schedule of rates, planning, and a full audit trail on every job from first survey through to invoice.”

In their own words.

“We're a property maintenance business, not a tech company. We came to Code23 with 30 years of industry knowledge, a head full of ideas and a spreadsheet-and-whiteboard operation, and asked them to turn it into a proper platform. A year on, our office runs on it daily: clients, contracts, jobs, quoting against schedule of rates, planning, and a full audit trail on every job from first survey through to invoice.

What sets James and the team apart is how they work with you. Every founder call gets turned into something concrete within days - we'd describe how a job actually runs on site, and the next review we'd be clicking through a prototype of exactly that. They don't just take instructions either. When we asked for something that would have caused problems down the line, they said so and explained why, and they were usually right. You're getting a thinking partner, not an order-taker.

The bit that's impressed us most is the field app. They sat with us, pulled apart how our operatives really work - van checks, materials, RAMS, evidence photos, resident sign-off - and designed an app around the reality of the job, not a generic form-filler. Our engineers are not app people, and it's built so they don't need to be.

Responsive, straight-talking, and they genuinely understand how a trades business operates, which is rare in software people. We're now taking the platform to market as a product in its own right, which tells you what we think of the build quality. Couldn't recommend them more highly.”

What needs to be solved before an AI product goes live

Plastor's carriage model was trained on 13,371 real orders and now supports live operations. Every AI product we build has to meet the same standard: useful, secure and reliable enough for people to depend on.

[ 01 ]

A good demo that never becomes a useful product

An early prototype can look impressive without being secure, reliable or ready for the people who need to use it.

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

We couldn’t be happier with the service from Code23. They were a pleasure to work with—friendly, professional, and really took the time to understand our needs. They met our brief perfectly, delivering a website that looks great and performs exactly as we envisioned, all at excellent value for money. What sets Code23 apart is their aftercare. Knowing they are on hand to monitor and maintain our website means we never have to worry about its performance. Their ongoing support gives us complete peace of mind, and we’d highly recommend them to anyone looking for a reliable and skilled web development team

It has truly been a fantastic experience working with the Code23 team. Every part of the process from the scoping and onboarding down to the design and implementation of our website was handled excellently. The quality of service delivered by the team is globally top standard and I couldn't be more satisfied with the final outcome.

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.

Excellent customer service and quality throughout and the build they have now completed is fantastic - exceeded all expectations across the board. Fantastic company with a dynamic and motivated team who are great to work with. Would highly recommend!

AI development questions

How do we choose an AI development company?

Look for working examples, direct access to experienced developers and a clear approach to testing, privacy and support after launch. We are based in Reading, have more than 60 five-star Google reviews and can show AI work for Plastor, Opsko, Oditable, OI Group and ESHP.

What does a custom AI build include?

It normally includes product design, the AI model or agent, connections to your data and systems, user permissions, quality testing, security, monitoring and support after launch. The exact scope depends on the problem you need to solve.

How much does AI development cost, and how long does it take?

The cost and timeline depend on the data, integrations, product complexity and level of testing required. A Discovery Sprint gives you a fixed scope, price and delivery plan for the first release before the main build begins.

How do you handle privacy and quality?

We agree permissions and UK GDPR requirements at the start, test answers against known examples, review security and monitor the product after launch. Important actions can require human approval, and the system can be paused safely if something goes wrong.

Can you integrate AI into our existing product?

Yes. We can add AI agents, document search or predictive tools to software you already use. You don't need to replace the whole product. If your main aim is to improve a repetitive business process, AI automation may be a better fit.

What support do we get after launch?

Every milestone build includes a 90-day warranty from launch covering defects against the agreed specification. Ongoing Support & Growth subscriptions are available when you want a senior team on the product after warranty.
