Anthropic

Claude, working alongside the people who know your brand.

Anthropic builds Claude, a family of AI models known for careful reasoning, strong writing and handling long documents well. For marketing teams, that makes Claude well suited to analysis, planning and drafting. The value comes from building it into how work actually happens. We design agents and workflows on Claude that connect to your data, follow your brand and keep experienced people in charge of the decisions, the same approach behind our agentic marketing platform.

Every part of Claude, designed and working together

Your AI starting point

We start by understanding how your team uses AI today, which tasks take the most time and where judgement matters most. You see clearly where Claude can help, where it should not be used and a prioritised plan for what to build first.

An AI agent built on Claude

Every AI programme we build comes with agents that work from your live marketing data and documents. Ask what customers are saying, what is performing or where to focus, and get a considered answer grounded in your own information.

They read, analyse and draft in minutes. Our team reviews every recommendation before it is acted on, so no budget, campaign or customer message changes without an experienced person checking it and signing it off.

You
What are customers saying about the new product range?
Across recent reviews and support conversations, customers like the quality but find sizing unclear. I have grouped the main themes and drafted copy changes for the product pages for your team to review.
You
Which channels should get more budget next month?
Search and email are both ahead of last month on return, while one social campaign is slowing. I have outlined a reallocation with the reasoning, for your team to approve before anything changes.

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.

Anthropic and Claude questions, answered

What is Claude and how is it different?

Claude is a family of AI models built by Anthropic. It is widely used for writing, analysis, research and coding, and is known for careful reasoning, a natural writing style and handling long documents well. Teams can use Claude directly through its apps or build it into their own systems through the API. For marketing, those strengths suit tasks such as analysing feedback, planning campaigns, reviewing copy and drafting content that needs to sound considered.

What does an Anthropic agency do?

An Anthropic agency helps you put Claude to work in your business. At Vertical that covers AI audits, agent design, workflow integration, analysis tools, governance and training. Because we also run paid media, email, CRM and content, we understand the work these tools are meant to support. We are an independent agency, and we build with Claude where it is the right fit for the task in hand.

How can marketing teams use Claude?

Marketing teams use Claude to analyse campaign performance, read and summarise customer reviews and research, plan campaigns, draft and edit emails, ads and product copy, review content against brand guidelines and prepare reports. The biggest gains come when Claude is built into structured workflows and agents rather than used occasionally. That keeps outputs consistent, grounded in your data and reviewed by the right people before anything goes out.

Can Claude connect to our marketing tools and data?

Yes. Through the API, automation platforms such as Make, n8n and Zapier, or protocols that let models use external tools securely, Claude can work with your CRM, analytics, ad accounts, email platform and documents. That means agents can analyse real performance and draft content based on current information. Our <a href="/services/agentic-automation" class="vb-inline-link">agentic automation</a> team designs these connections with clear permissions and review steps.

How do you keep Claude content on brand?

We ground every workflow in your tone of voice, brand guidelines, product information and approved claims, so Claude starts from the right context each time. It drafts, and experienced writers and editors review, refine and approve before anything is published. We also check for invented facts and claims you cannot support. The result is content produced faster that still sounds like you and stands up to scrutiny.

Is it safe to use our business data with Claude?

It can be, with the right setup. We help you decide what data should and should not be shared, review the relevant workspace and API data settings and configure access so only the right people and systems use it. Sensitive information can be excluded or anonymised. We document clear policies, so your team knows what is appropriate and AI use stays consistent and accountable across the business.

Should we use Claude or OpenAI models?

Both offer excellent models with different strengths, and the right choice often depends on the task, your existing tools and how your team prefers to work. Some businesses standardise on one, while others use different models for different jobs. We work with both, test them on your real tasks and recommend what performs best. Our <a href="/services/ai-solutions-development" class="vb-inline-link">AI solutions development</a> work is model-agnostic by design.

How do you help our team adopt Claude?

We run practical training built around your team's actual work, showing how to brief Claude well, review its output critically and build it into daily routines. We pair that with shared guidelines, reusable prompts and well-organised project knowledge, so good habits are easy to follow. Our <a href="/services/ai-training-and-adoption" class="vb-inline-link">AI training and adoption</a> programmes focus on lasting, confident use rather than one-off sessions.

How do we get started with Vertical?

Start with a conversation about how your team uses AI today and where time is being lost. We usually begin with a short audit of current tools, tasks and data, then share a prioritised plan covering quick wins and larger builds. We will tell you plainly where Claude will make a real difference to your marketing and where another approach would serve you better.

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