AI integration and advisory, London

Bring AI into the work
your firm already does.

Forthen helps small, white-collar firms put AI to work where it genuinely helps. We map your business into its workflows, identify the functions worth automating, and build the tools around how you already operate. Nothing is automated without your say.

The idea

Every business is a set of workflows. Every workflow is a set of functions.

Product. Hiring. Marketing. Client communications. Internal communications. Each of these is a workflow, and each workflow breaks down into the smaller functions that make it run. Some of those functions are a natural fit for AI. Many are not, and should stay exactly as they are. Our work is telling the difference, and then doing something about it.

01

Workflow

The broad areas of your firm, from how you win clients to how your team talks to each other.

02

Function

The concrete, repeatable jobs inside each workflow. Drafting, summarising, researching, reviewing, scheduling.

03

Automated, with your consent

Only the functions you choose. We build the tool, you keep control of where AI does and does not touch your business.

What we do

Custom integration, built around your firm.

We are not a software product you log into and figure out alone. We sit with you, learn how your firm works, and build AI into the functions you want help with. Then we teach your people to use it and extend it themselves.

We listen first

We work closely with you to map your workflows and decide, function by function, where AI belongs and where it does not.

We build the integration

We implement the right AI tools into the exact functions you have chosen, configured for your firm rather than off the shelf.

We hand over the keys

We train your management and staff on how the tools work and how to apply them, so the capability stays inside your firm.

The full toolkit, applied with judgement.

Questions

Frequently asked

Do you replace our staff with AI?

No. We automate functions you choose, and we train your people to use the tools. The aim is to make your team faster and free them for higher-value work, not to remove them.

What size of firm do you work with?

We focus on small, white-collar firms in and around London. If you are a professional services or knowledge-led business, we are likely a good fit.

Which AI tools do you use?

We work across Claude and ChatGPT and their wider ecosystems, alongside careful prompt engineering. We choose the tool that fits the function.
