AI Agency in London

Mismi is a custom AI agency serving London businesses. We design and ship AI systems tailored to how London companies actually run: private internal assistants, customer-facing AI products, bespoke conversion-focused websites, and AI discoverability so you get cited when a customer asks ChatGPT or Google for a recommendation.

Every project is scoped in writing, priced up front and owned outright by you when it ships. No day rates that drift, no licence you rent forever, no black box. You work directly with the specialist building it.

London AI, questions answered

Are you a London-based AI agency?

We serve London clients constantly and are based a short train ride away in the South East, which keeps rates sensible without losing face-to-face time. Discovery workshops and key meetings happen in person in London; the build runs remotely with weekly updates.

What kinds of AI projects do you take on for London businesses?

Private internal assistants trained on your own documents and workflows, customer-facing AI products and agents, bespoke AI-powered websites, and AI discoverability so you rank on Google and get cited by ChatGPT, Claude and Perplexity.

How much does a custom AI project cost?

Every project is priced against a written scope after a free intro call, so you see a fixed figure before anything is built. Pricing depends on the system, not an hourly meter.

Will our data stay private and stay ours?

Yes. Internal assistants are built on your knowledge and permissions, and your data never trains anyone else's model. The finished system is owned outright by you, not licensed back to you.
