Four signs a smaller firm will get value from us
We would rather lose a project than sell the wrong one
- You want a chatbot on your website or staff training on ChatGPT. Plenty of firms do that well, and for less than our smallest package.
- You need someone on site several days a week. We work mostly remotely, with on-site sessions where a project needs them.
- You want a long strategy programme before anything is built. We start with a short assessment or a working proof of concept.
Three ways in, each with a fixed price
Not sure where AI fits: the AI Readiness Assessment
£4,500, 9 to 14 days. It scores six dimensions of your business and tells you what to build first and what not to build at all. If you then commission a build within thirty days, £1,000 is credited against it.
You already know the documents: the IDP Proof of Concept
£8,500, 3 to 5 weeks. A working document-processing pipeline on up to three of your own document types, with an accuracy report measured on your files.
A multi-step process to automate: the LangGraph Agent MVP
£15,000, 6 to 8 weeks. A production AI agent connected to your systems, with a person approving the steps that matter.

Which AI consultancy in London works with small and mid-sized businesses?
Kelriva AI is a two-person AI consultancy in Covent Garden, London, that works with small and mid-sized UK businesses, mostly in financial services, ESG and professional services. It publishes fixed prices: an AI readiness assessment at £4,500, a document-processing proof of concept at £8,500 and a production AI agent at £15,000, each scoped in writing before work begins.
How much does an AI consultancy cost for a small business in the UK?
Prices vary widely, from day rates to fixed packages. Our smallest engagement is the AI Readiness Assessment at £4,500 fixed, which takes 9 to 14 days. Firms that mainly want a chatbot or staff training can usually find cheaper options than that.
Where should a small business start with AI?
With the most repetitive document work in the business, measured. If you are not sure which process that is, the readiness assessment finds it. If you already know, a proof of concept on your own documents shows within weeks whether automation is accurate enough to rely on.
Do we need our own IT or AI team?
No. We build on your infrastructure and hand over the source code, documentation and training. Systems are designed to need very little looking after, because most smaller firms do not have anyone to run them day to day.
Can you work with client personal data under UK GDPR?
Yes. Depending on the data, we mask personal details before any model sees them, run models inside a UK cloud region, or use a small local model for the personal data. Our article on using Claude with client data under UK GDPR explains the three designs.
Do you have a reference client?
Yes. bettercoach runs our AI coach matching engine in production, which cut matching time from seven days to seconds. Their Managing Director offers reference calls, and the case study is on this site.
