AI Solutions Development

Built around your business, not someone else’s template.

Off-the-shelf tools go a long way, but some problems are too specific for them. A recommendation engine that understands your catalogue. An assistant trained on your knowledge base. A system that turns your data into decisions your team can act on. We design and build AI solutions for the challenges that matter most to your business, then make sure they keep performing as you grow.

Solutions shaped by the problem

Custom Assistants

Assistants for customers or staff that draw on your own products, policies and knowledge, answer accurately in your brand voice and know when to hand over to a person.

From a question to a working tool

The solutions we build sit inside the tools your team already uses, so insight turns into action without another dashboard to check.

Every model is tested against your own data before launch, monitored once it is live and reviewed by our team, so you can trust what it tells you and see why.

You
Which customers are likely to stop buying?
A group of previously regular customers has gone quiet over recent months, mostly in two product categories. I have listed them with their purchase history and suggested a tailored win-back offer for each segment.
You
Can that run automatically?
Yes, once approved. The model would refresh weekly and pass each new group to your email platform, with performance reported back so the offers can be refined over time.

Why build with Vertical

We combine AI engineering with deep experience in brand, marketing and customer journeys, so what we build is useful from day one and fits how your business works.

Problem first

We start with the business challenge and only build when a custom solution is clearly better than an existing tool.

Designed for people

Our designers make sure every solution is clear, usable and on brand, whether it faces customers or your own team.

Proven before scaled

We prototype quickly, test with real users and data, then scale what works, so investment follows evidence.

Secure and responsible

Data protection, access controls and responsible AI practices are built into every project from the start.

Yours to own

Clear documentation and sensible architecture mean you are never locked into a black box you cannot understand.

Supported for the long run

We monitor, maintain and improve what we build as models, platforms and your business change.

View case study

A powerhouse in a Power Station.

Vertical is a small, senior team of strategists, creatives and performance marketers based at Battersea Power Station in London, with clients and colleagues around the world. Strategy, creative and performance come from one team, with AI built into how we plan, make and measure.

The building has stood on the Thames for the best part of a century, and for fifty years it kept London’s lights on. We like the precedent.

AI solutions questions, answered

What is AI solutions development?

AI solutions development is the design and build of custom software that uses artificial intelligence to solve a specific business problem. That might be a customer-facing assistant, a personalisation engine, a predictive model, a knowledge search tool or a content production system. Unlike off-the-shelf products, these solutions are shaped around your data, processes and customers, which makes them more accurate and more useful for the task at hand.

When should we build rather than buy?

Buy when an existing tool solves the problem well enough, because it will be faster and cheaper. Build when your needs are specific to your business, when the solution needs to draw on your own data in ways standard tools cannot, or when the capability is a genuine source of competitive advantage. We help you make that call honestly, and we often recommend combining existing platforms with custom elements rather than building everything from scratch.

What kinds of solutions do you build?

Common projects include customer and staff assistants trained on company knowledge, product recommendation and personalisation engines, churn and lifetime value models, lead scoring, demand forecasting, automated content pipelines and internal search tools. Most connect to platforms such as Shopify, HubSpot, Klaviyo, Google Analytics and data warehouses, so results flow straight into the tools your team already uses.

How long does a project take?

It depends on the scope, but we work in stages. A working prototype is often possible within a few weeks, which lets you test the idea with real data and users before committing further. A production-ready solution typically follows over the next one to three months. Larger systems are delivered incrementally so value arrives early and the build stays aligned with what users actually need.

How do you make sure the AI is accurate?

We test every solution against your own data and real scenarios before launch, define what acceptable accuracy looks like for the task and build in checks such as source citations, confidence thresholds and human review where the stakes are higher. Once live, we monitor performance and retrain or adjust when results drift. You can always see how the system reached its answer.

Is our data safe?

Data protection is designed in from the start. We use secure, reputable infrastructure, apply strict access controls, keep data within agreed regions and avoid sending sensitive information to services that would use it for training. We work within UK GDPR and your own security requirements, and we document how data flows through every solution we build.

Which technologies do you use?

We choose technology to suit the problem rather than favouring one vendor. That typically includes leading language models from providers such as Anthropic, OpenAI and Google, alongside established cloud platforms, vector databases and the APIs of the marketing and ecommerce tools you already use. We favour proven, maintainable components so your solution remains supportable for years, not months.

Who owns what you build?

You do. We agree ownership of code, models and data at the start of the project, and we document everything clearly. If you later want to bring the solution in house or move it to another partner, you can. We would rather earn ongoing work by keeping your solution performing well than by making it hard to leave.

Do you support solutions after launch?

Yes. Most clients choose an ongoing support arrangement covering hosting, monitoring, maintenance and improvements. AI models and connected platforms change frequently, so regular care keeps the solution accurate, secure and useful. We also review performance with you and suggest improvements as usage grows and new opportunities appear.

How do we get started?

Start by telling us about the problem you want to solve. We will explore it with you, look at the data and tools involved and give you a straight view on whether a custom solution makes sense. If it does, we usually propose a short prototype phase so you can see results quickly before deciding on the full build.

Bring us the ambition. We’ll build the system behind it.
