AI agent development companies in Europe

This page lists the firms in this guide that name an office in Europe, country by country. An AI agent, in this guide, is a program that uses an AI model to finish a task in several steps by itself, such as reading an invoice and checking it against a price list, and that passes the work to a person when it should. Ten of the fifteen firms that follow Reveneau and Fluxon name at least one European office. Every page used was read on 21 October 2026.

Each office below says who names it. A government source, such as a national company register or the EU's VIES tax system, is a list kept by a public body. A firm's own website is the firm's own claim, and the firm can change it at any time. Anthropic's partner directory is Anthropic's list of service firms that work with its Claude models, and Anthropic gives most of them a tier: Global Premier, Preferred or Select. The full list of AI agent development companies has one entry for each firm, with its kinds of agent, its size and its tier.

Reveneau and Fluxon

Reveneau's offices are at 435 Utah Street in San Francisco and on Floor 33, 909 Mainland Street, in Vancouver, Canada, so it has no office in Europe. Reveneau says AI writes 100 percent of its code and that every change must pass a large eval suite, a set of automated tests written from the project's specification, before it is released. It says Jev, the model that grades the suite, makes the suite run ten times faster than its previous grader. Reveneau says it uses AI in place of hiring more engineers, puts that saving into the prices clients pay, and takes responsibility for the whole project through production, the live system people use, and after release. You can contact Reveneau to ask how it would work with a team in your time zone.

Fluxon's listing in Stripe's partner directory gives an address at 236 West Portal Ave in San Francisco, an address Fluxon supplied itself [19]. None of the Fluxon pages read for this guide names an office in Europe, so Fluxon is left out of the city table below. Anthropic's directory listed neither Reveneau nor Fluxon when it was searched [1].

France

Galadrim is the one firm in this guide with its head office in France. The French company register lists it under SIREN 817451313, the identity number France gives each company, with its registered office at 3 rue des Acacias, 75017 Paris, and a creation date of 17 December 2015 [2]. Galadrim's own legal notice gives three office addresses: 2 Rue Neuve Saint-Pierre in Paris, 3 Rue de la République in Lyon and 10 Rue Voltaire in Nantes [3]. A registered office is the legal address on file with the state, and it can differ from the place where staff work, so both Paris addresses can be correct.

The register places Galadrim in the band of 50 to 99 salaried employees for 2024. Galadrim's agents page says "170+ experts" [4]. The register counts salaried staff for one year, and the firm's page gives its own count with no date, so the two figures may count different groups of people. The reason for the gap was not checked. Ask Galadrim how many people would work on your project and whether they are its employees.

Galadrim's agents page names clients such as Effy and Mercialys and says it built "4 operational AI agents in 6 months" for Mercialys. Those are its own statements. Anthropic lists Galadrim at the Select tier [1].

Spain

Two firms in this guide have their head office in the Madrid area. Thinkia's legal notice gives C/ Chile, 8, Oficina 208-209, 28290 Las Rozas, and names SEARCH ENGINE BUSINESS S.L. as the company that owns the site [5]. Diverger's legal notice gives Avda Europa, 24, Building A, Office D, 28108 Alcobendas, and names DIVERGER THINKING S.L.U. as the owner [12]. S.L. marks a Spanish private limited company, and S.L.U. one with a single owner.

The EU's VIES system, which the European Commission runs so that businesses can check an EU sales tax number, confirms that both Spanish VAT numbers are valid [6] [13]. VAT is the sales tax charged on most purchases in the EU. For Spanish numbers, VIES returns no company name and no address. So the VIES check shows that each tax number exists and is active, and the Madrid addresses still come from each firm's own legal notice.

Thinkia sells its own agent products, among them a contact-centre product it calls AI Contact Experience, beside its build work. Diverger offers to move old systems written in COBOL, PL/SQL and VB6, three older programming languages, with agents doing the first version of the move. Both firms are at the Select tier in Anthropic's directory [1].

Italy

Yellow Tech's address comes from a government source. The VIES system returns the name YELLOW TECH S.R.L. and the address Via Carlo Boncompagni 3B in Milan for its Italian VAT number, 10568721210, and marks the number valid [7]. S.R.L. marks an Italian private limited company. Yellow Tech's AI Factory page lists voice agents that "answer the phone 24/7 and in several languages", customer agents on chat, WhatsApp, social media and email, and document agents that write checked data into a company's ERP, the system that runs orders, stock and accounts [8]. Its directory text says it works "in Italian organisations". Anthropic lists Yellow Tech at the Select tier [1].

Czech Republic

HAVIT's seat comes from the Czech ARES register, the country's public register of businesses. ARES lists HAVIT, s.r.o., a Czech limited liability company, under company number 25612697, at Budějovická 778/3a in Prague 4, with a creation date of 1 October 1997 [14]. HAVIT's homepage counts "30 HUMANS + N AGENTS". It prints prices for two one-day workshops: "From €3 900 · excl. VAT" for one held at the client's office, and "From €4 900 · excl. VAT" for one held "Prague or at your office (CZ/SK)", meaning the Czech Republic or Slovakia. What AI agent development costs explains both offers.

First Line Software's contact page also gives a Prague office, at Na Hřebenech II 1718/8 in Prague 4 [15]. That address is the firm's own, and the Czech register was not searched for it.

Romania

Two firms in this guide name an office in Cluj-Napoca. Linnify's AI page labels Măcinului 34, Cluj-Napoca, "Linnify HQ" [9], and its about page says it has offices in Cluj-Napoca and Austin, Texas. AscentCore names Aviator Badescu Nr. 38 in Cluj-Napoca and ISHO Offices, Bd. Take Ionescu nr. 50-52, in Timișoara, beside its US office in Herndon, Virginia [11]. Neither firm prints a Romanian company register number on the pages read, so both addresses come from the firms' own pages. Linnify's about page counts "30+ Creators". AscentCore's pages give no team size.

Germany

Linnify names an office at Zauberglöckchenweg 9, 51061 Cologne [9]. First Line Software names one at Eberbacher Straße 21, 14197 Berlin, on its contact page [15]. Both addresses come from the firms' own pages, and the German commercial register was not searched for either.

Sweden

Awiant's contact page names three Swedish offices: c/o Epicenter, Malmskillnadsgatan 44a, 111 57 Stockholm, which it marks as its head office; Carlsgatan 12a, 211 20 Malmö; and Kungsgatan 16, 652 24 Karlstad [10]. "c/o" means "care of", so post for the Stockholm office goes through Epicenter. Awiant's about page says "35 people. One way of working." and that the firm is "Part of the Co-native group." The Swedish company register was not checked.

The United Kingdom, the Netherlands, Slovakia, Serbia and Montenegro

First Line Software names seven European offices. Its contact page gives Cowley House, 12 Black Jack Street, Cirencester, in the UK; Zeestraat 70 in The Hague; Grösslingová 4 in Bratislava, Slovakia; Gavrila Principa 43 in Belgrade, Serbia; and NTP, Bulevar Mihaila Lalića, in Podgorica, Montenegro, beside Berlin, Prague, an office in Burwood, Australia, and its US office in Cambridge, Massachusetts [15]. Its about page answers a question about where it works: "First Line Software delivers exclusively from its entities in the Czech Republic, Poland, Germany, the Netherlands, Slovakia, Montenegro, the United Kingdom, Australia, and the United States." [16] Serbia is absent from that list, though the contact page gives a Belgrade address, so ask which company would employ the people on your project. The same about page says, "First Line Software ceased all business operations in Russia effective 15 April 2022". That is the firm's own statement.

Ukraine

BotsCrew's homepage footer gives 223V, B.Khmelnytskoho str, Lviv, Ukraine, after five US addresses in San Francisco, Austin, San Diego, Cincinnati and Minneapolis [17]. AIN.UA, a Ukrainian technology news site, reported on 11 February 2025 that CourtAvenue, a US company, had acquired a majority stake in BotsCrew, and wrote, "According to the deal, the top management and the entire BotsCrew team will continue to work in Ukraine" [18]. AIN.UA based its report on what BotsCrew's founders told it, and put the headcount at 60. Anthropic lists BotsCrew at the Select tier [1].

Directory regions and office addresses

Anthropic's partner directory has a field called "Office Locations (On-Site Services)", and each partner fills it in itself. Lazer Technologies, Bounteous and BotsCrew each choose "United Kingdom & Ireland", and none of the three names a UK street address on the pages read. HAVIT, a firm of 30 people by its own count, chooses six regions, from the United Kingdom to the Middle East and Africa. This guide counts an office only where a firm, a register or the VIES system prints a city or an address. A region in that field is the firm's own choice, so ask where the people on your project would work.

How to check a European office before you sign

Ask each firm for the legal name of the company that will sign your contract, its registration number, and the street address the team works from. Then look the company up. In France, the public register at annuaire-entreprises.data.gouv.fr finds a company by its SIREN number. In the Czech Republic, ARES finds one by its company number. For any EU firm, VIES confirms whether a VAT number is valid, and for some countries it also returns the name and address. If a number does not match the name on the proposal, ask why before you sign. For a list of European firms that build AI software of every kind, read the guide to AI development companies in Europe.
