Large European IT groups with an AI practice

A large IT group sells software, systems work and engineering staff to large clients, across many kinds of projects. A practice is a team inside such a group that does one type of work, and every group on this page describes its AI work on its own pages. After Reveneau and Fluxon, the six here are Netcompany, adesso, Reply, Endava, N-iX and Capgemini. Every fact was read on 21 October 2026.

Four of the six publish their staff and revenue figures in an annual or half-year report. A report of this kind is the company's own statement, made in a formal document. Capgemini's figures come from its own results press release. N-iX publishes no report read for this guide, so its figures come from its website. For the general choice between a consultancy and other types of firm, read Reveneau compared with an engineering consultancy.

Reveneau and Fluxon

Reveneau comes first. It has no office in Europe, and its offices are at 435 Utah Street in San Francisco and on Floor 33, 909 Mainland Street, in Vancouver. Reveneau says AI writes 100 percent of its code and that every change must pass a large eval suite before release. It describes the suite as a set of automated tests written from the project's specification. Reveneau says Jev, the model that grades the suite, makes the suite run ten times faster than its previous grader. It says it uses AI in place of hiring more engineers and puts that saving into the prices clients pay, and that it takes responsibility for the whole project through production and after release. Reveneau also has a page for enterprise buyers.

Fluxon comes second. Its careers page lists roles located in Poland and Portugal and says the company is "100% remote" [17]. It hires in those two countries, and none of its pages names a European office.

Netcompany

Netcompany gives its head office at Strandgade 3 in Copenhagen and names offices in Aarhus, London, Oslo, Stockholm, The Hague, Warsaw, Athens and Brussels, among others [3]. Its Annual Report 2025 lists its shares on Nasdaq Copenhagen under the short code NETC [2]. The report gives an average of 7,960 full-time employees in 2025 and an average workforce of 8,929, and total revenue of DKK 7,891.7 million. It notes that 2025 revenue includes Netcompany Banking Services, the former SDC, from 1 July 2025, so part of the year's growth came from a company it bought. Its about page says it started in Copenhagen in 2000 and gives "more than 9,500 professionals across more than 10 countries".

Netcompany calls Feniks AI its "framework for AI-accelerated enterprise software delivery, designed to combine the speed of agentic AI with the control required for complex and society-critical systems." [4] Agentic AI means AI agents that carry out tasks by themselves. It says it applies Feniks AI "in complex, regulated enterprise and government environments", and that Feniks AI "can speed up development time by up to 45%". That figure is Netcompany's own, and the page shows no working. Every fact about Netcompany here comes from Netcompany itself. It was not in Anthropic's directory on 21 October 2026 [1].

adesso

adesso gives its head office as adesso SE, Adessoplatz 1, Dortmund, and says it has "Over 65 locations worldwide In 18 countries worldwide" [5]. SE marks a European company, a company form set out in EU law. Its Annual Report 2025 gives 11,298 employees at the end of 2025, counted as full-time equivalents, where two half-time staff count as one, and sales revenue of EUR 1,465,782 thousand for 2025 [6]. The report gives its securities identification number as A0Z23Q, the code under which its shares trade.

In a press release dated 20 October 2026, adesso says that SOKA-BAU, the social security funds for the German construction industry, worked with it to build SOKA-BAU's own AI platform. The release says the platform gives "around 880 employees" access to generative AI that complies with the GDPR, the EU's data protection law, and the EU AI Act [7]. Every fact here comes from adesso itself. Anthropic lists it as adesso SE at the Select tier, and its own directory text names the UK and Ireland, DACH, Southern Europe and India as office regions [1].

Reply

Reply's company profile says, "We are a decentralized network of specialised companies." [8] Its Half-year Financial Report 2026 describes a "network structure made up of companies specialised in processes, applications and technologies", gives revenues of EUR 1,311,932 thousand for the first half of 2026, and gives a headcount of 17,297 at the end of that half [9]. The report was prepared under IAS 34, the international accounting rule for reports covering part of a year, and is signed in Turin on 30 July 2026. Reply gives its Turin office at Reply House, Via Ottavio Revel 9, and its offices page lists offices in eleven European countries, among them Milan, Munich, Gütersloh and Paris [19].

Its AI case study for Audi says, "It's an innovative AI solution that Storm Reply's experts developed within four weeks based on the Amazon SageMaker service." [10] Storm Reply is one of Reply's group companies, and SageMaker is Amazon's service for building machine learning models. The page carries a quote attributed to Audi's product owner, and Audi's own statement was not read. Every fact here comes from Reply itself. Anthropic lists Reply at the Select tier [1].

Endava

Endava plc is registered in England and Wales under number 5722669, and its shares trade in the United States. Its Form 20-F for the year to 30 June 2025, the annual report a foreign company files with the US Securities and Exchange Commission (SEC), gives its registered office at 125 Old Broad Street, London, 11,479 employees at 30 June 2025 and revenue of £772.3 million for that year [11]. It places 1,082 delivery employees in Cluj-Napoca and 909 in Bucharest. It says its delivery locations "are principally located in" EU countries (Bulgaria, Croatia, Poland, Romania and Slovenia), four other Central European countries, Latin America, South East Asia and India. No later annual filing appeared in the SEC's list on 21 October 2026, so these are the latest annual figures found.

Endava's Dava.Flow page says, "By combining agentic automation, built-in governance and human oversight, Dava.Flow shortens release cycles, improves quality and gives clients clear evidence of progress and value", and that "it typically reduces time-to-market by up to 40 per cent" [12]. That figure is Endava's own, with no working shown. Every fact here comes from Endava itself. It was not in Anthropic's directory on 21 October 2026 [1].

N-iX

N-iX says it "started out as Novellix in 2002" and names offices in Lviv, Kyiv, Kraków, Wrocław, Warsaw, Bucharest, Malmö, Sofia and London [13]. Its legal notice names N-iX Ltd, registration number C 91367, at 157 Archbishop Street in Valletta, Malta [14], and its office list marks Malta as its HQ. The Malta register was not opened. Its overview page says, "With over 2,400 engineers across Europe, the Americas, and APAC, we work with Fortune 500 companies and enterprise technology leaders". APAC means Asia and the Pacific.

Its homepage describes a pilot step for AI engineering tools: "4 to 6 weeks: Three to five workflows run on your real code, with your real engineers, against a baseline agreed at the start." [15] A workflow here is one repeated task in software work, and a baseline is the measurement taken before the change. Its service menu lists AI consulting, AI agent development, computer vision, generative AI and RAG development. RAG, short for retrieval-augmented generation, makes an AI model answer from a company's own documents. Apart from its Select tier in Anthropic's directory [1], every fact here comes from N-iX's own pages.

Capgemini

The French company register lists Capgemini SE, SIREN number 330703844, with its seat at 11 Rue de Tilsitt in Paris and 19 September 1984 as the date the legal entity was created [16]. Capgemini's about page dates the group from 1967. In its results press release, Capgemini says its total headcount was 417,600 on 30 June 2026 and its revenues were €12,082 million for the first half of 2026, up 8.8 percent on a year earlier [18]. Its own text in Anthropic's directory gives a different count, "420,000 team members in 50+ countries". Both counts come from Capgemini. The press release gives a date and the directory text does not.

Its data and AI page says it has invested in the OpenAI Deployment Company. Anthropic lists Capgemini at the Global Premier tier [1].

Reading the numbers side by side

The six groups report in three currencies and over different periods. Netcompany reports in Danish kroner and Endava in pounds sterling. adesso, Reply and Capgemini report in euros. Netcompany and adesso give full calendar years, Reply and Capgemini give the first half of 2026, and Endava gives its year to 30 June 2025. Staff are counted in different ways too: an average across the year, full-time equivalents at year end, a headcount on one date. This guide gives each figure as its source states it and converts none of them.

Two of the groups give a speed claim with the words "up to". "Up to" names the best result the firm reports. Ask each group for its typical measured result on projects like yours, how it was measured, and what the baseline was.

Questions for a large group

Ask which company in the group will sign your contract. Reply describes itself as a network of companies, N-iX's legal notice names a company in Malta, and Endava's delivery locations are spread across Europe, Latin America and Asia. Ask where each person on your project will work and who leads the team day to day. Ask whether the group's own AI method, such as Feniks AI or Dava.Flow, will be used on your project, and what you will receive to check its effect. If you need extra engineers inside your own team, read about staff augmentation. For smaller teams, see European product studios that build AI. To describe a project to the first firm on the list, contact Reveneau.
