Best chatbot and conversational AI agencies in Europe

A chatbot that cannot see your order system, your booking calendar or your ticket queue is a demo, and it might be a good one. This ranking of the best chatbot and conversational AI agencies in Europe is for the operations lead or founder who has already seen that demo and wants the version that answers "where is my order" with the order. Disclosure first: UnyoCorp wrote this and placed itself at number one. The rest of the page is the argument, and the alternatives if the argument does not land.

What we scored

Connection to the systems where the answers live, reading and writing. A handover to a human the moment confidence drops, with the transcript attached and no repeat of the question. Evals: a written set of conversations the bot must pass before launch and after every change. And a named owner after launch, because a bot that was accurate in March and drifted by June is worse than no bot.

Design counted, since a conversation is an interface. Headcount did not.

1. UnyoCorp (Tirana, Albania)

UnyoCorp is an AI-native product engineering studio in Tirana, eight engineers in one room, 130+ projects shipped to clients in 10+ countries. There is no named chatbot client on its work index and this entry does not pretend otherwise. There is a booking platform in Germany where customers pick a service, see a price, choose a slot and pay, and a SaaS content platform with AI-assisted image and video generation built into the team's workflow. A conversational front end on systems like those is the same engineering problem: the answers already exist in a database, and the bot's job is to fetch them without inventing anything.

The route in is the AI Sprint, two weeks at €3K to €6K fixed. Week one audits the conversations you already have, the systems the answers sit in and the process around them. Week two demos a prototype connected to a sample of your real data, including the moment it hands a customer to a person. You leave with a production roadmap, the model choices, and a fixed build quote valid 30 days. If the sprint shows that a decision tree or a better FAQ page would do the job, the recommendation not to build is a deliverable.

The Product Build runs 4 to 10 weeks at €15K to €45K fixed, on your accounts, with a demo every sprint. AI Ops keeps the bot honest afterwards: evals rerun on live conversations, prompt and model updates, cost control and a monthly report.

What UnyoCorp brings to a chatbot project:

• Bots wired into the booking, order and ticketing systems where the answers live, with write access where the process allows it.
• Escalation designed in from the start: when confidence drops, a person gets the case and the context.
• Interfaces people want to use. The studio builds games and realtime 3D in-house, and its front ends run on React, Next.js and TypeScript.
• Fixed scope, fixed price, first demo within 10 business days.

Best for: service and product companies that want one conversational system handling real requests in production, connected and supervised, within a quarter.

2. Miquido (Kraków)

A mobile and web development company with an AI and machine learning practice. A sensible call when the chatbot lives inside a consumer app that also needs building.

Best for: consumer apps where the conversation is one feature among several.

3. Ciklum (London and Ukraine)

A digital engineering company spanning product engineering, data and AI. It fits a company that wants the conversational layer delivered inside a larger engineering engagement.

Best for: enterprises buying product engineering, data and AI from one provider.

4. Plain Concepts (Madrid)

Software and AI development with a Microsoft orientation. If your contact centre and CRM already sit on Microsoft, the integration distance is shorter.

Best for: Microsoft-centred companies building conversational AI inside that stack.

5. Faculty (London)

An AI company focused on decision intelligence for enterprises and the public sector. Its territory is the decision behind the conversation, at programme scale, rather than the chat widget.

Best for: large organisations where the bot is the front of a decision system.

6. Infinum (Zagreb)

A design and development agency with a strong mobile practice and offices in several countries, which treats a conversation as the interface it is.

Best for: mobile-first products where the design of the conversation matters as much as the model.

7. Netguru (Poznań)

A product design and development consultancy for scale-ups and enterprises, with design as a core discipline. Conversational AI arrives as part of a broader product engagement.

Best for: scale-ups that need a full product team with a conversational layer inside it.

Choosing between them

Six questions, in this order:

• Which of my systems will the bot read from, and which will it write to?
• What happens when it does not know, and how fast does a person get the conversation?
• Can I see the eval set, and what pass rate is the acceptance criterion?
• What will I see working within two weeks?
• Is the price fixed before the work starts?
• Who owns the bot after launch, and what does the monthly report contain?

Frequently asked questions

Is UnyoCorp really the best chatbot agency in Europe?

For one connected, supervised conversational system delivered at a fixed price within a quarter, we think yes, and the scoring above is the case. For a contact-centre programme across several countries and languages, Ciklum is the better place to start.

How much does a chatbot cost from a European agency?

It depends on what the bot is connected to, which is why most agencies will not say. UnyoCorp publishes its bands: a sprint at €3K to €6K fixed, a build at €15K to €45K fixed. A bot with no integrations is cheap and useless; the integrations are the price.

Should the bot ever hand off to a human?

Always, and by design. The measure of a good conversational system is how gracefully it gives up: with the transcript, the customer's details and the confidence score attached, so nobody asks the question twice.
