TREES has closed 2025 with a turnover of 22.5 million euros24% more than the previous year, and nearly 200 professionals on staff, consolidating twelve years of continued expansion based on organic growth. The Spanish consulting firm, one of the main partners of Microsoft in business applications, thus reinforces its position in the upper mid-market and the corporate segment, with a strategy that combines sector specialization, its own Artificial Intelligence platform and a talent model capable of maintaining turnover below 5% for more than five years.
What in 2014 was a structure of barely 20 people is today an organization that has almost 200 specialistswith presence in Madrid, Galicia, the Canary Islands, Cantabria and the Basque Country. During this time, ARBENTIA has opted for an expansion model without acquisitions, focused on developing internal capabilities and delving deeper into sectors where it can build differential value propositions.
In 2025, this approach has translated into growth in all industries where the company operates, with special traction in distribution and manufacturing, as well as retail, industry and food. The firm has also strengthened its position in construction, renewables and engineering, while consolidating its presence in process-intensive services (hotels, health, real estate, insurance) and in verticals such as automotive and machinery rental.
ERP as a pillar, AI and data as a lever
From a portfolio point of view, the bulk of the income continues to come from the ERP practicewhere ARBENTIA relies on the Microsoft business application stack. It is followed by the division of customer engagementwhich brings together CRM, sales, marketing and contact center capabilities, configuring an end-to-end service offering on the transactional and customer relationship layer.
The areas of modern workplace, data e Artificial intelligence They have also experienced growth, although in a more moderate way, maintaining a weight aligned with the business as a whole. The common thread is a pattern of increasingly integrated projects, in which the company expands the functional scope on existing clients (especially in high mid-market and corporate accounts) and adds advanced analytics and AI components on top of the core systems already deployed.
“Client zero”: internal agentic AI laboratory
The big news in 2025 has been the institutionalization of the “ARBENTIA client zero” strategy, through which the consulting firm becomes a test bed for AI solutions that it will later take to its installed base. To this end, it has set up a team specialized in AI and advanced analytics, responsible for identifying use cases, developing prototypes and validating their real impact on internal operations before packaging them as a commercial offer.
On this basis, ARBENTIA has developed ARBENTIA AI Knowledgea proprietary platform aimed at processing large volumes of documentation in controlled environments, capable of connecting multiple sources, interpreting them in natural language and generating configurable responses or outputs, relying on different AI engines. The tool allows you to narrow down a corpus of information and parameterize the behavior of agents according to each process, a key requirement for transferring generative models and autonomous agents to regulated business scenarios.
The company is already using this infrastructure to deploy internal agents aimed at operational efficiency, support and project management. In the support area, the agents who assist the teams have allowed reduce the average case resolution time by 73% during the last three months, an improvement that, when transferred to clients, could transform SLAs and service quality in critical environments.
In parallel, the use of assisted programming tools with Copilot has increased the productivity of the technical team by 95%according to internal ARBENTIA metrics. The cross-functional AI practice that articulates these deployments serves all sector divisions and is complemented by a formal change management plan to drive effective adoption of Microsoft Copilot among employees.
Talent: rotation less than 5% and structured career
The growth of the business has been sustained by a deliberate policy of attracting and retaining talent, which has made it possible to maintain turnover below 5% for more than five years, well below the usual levels of technology consulting specializing in Microsoft platforms. The company attributes this data to a structured professional career model, implemented more than seven years ago with external advice and documented for the entire organization.
This model includes differentiated itineraries by responsibility, vertical and horizontal promotion options, annual reviews and variable remuneration linked to individual objectives and continuous training. The stated objective is to offer visibility on professional progression and avoid the feeling of stagnation, one of the factors that weighs most in the flight of qualified talent in the sector.
Added to this structure is a sustained internal “quarry” strategy, articulated through the internship program which in 2026 reaches its eighth edition. Between March and July, ARBENTIA plans to recruit 35 final-year students—mainly STEM profiles and business degrees—from Spanish universities, who will undergo an initial month of intensive training before joining the different divisions with the accompaniment of a mentor.
Historically, more than 80% of the participants in this program have ended up joining the company on a stable basis, which turns the model into a strategic way to attract junior talent aligned from the first moment with the culture and sectoral specialization of the firm.
Position in the Microsoft ecosystem and prospects
With more than two decades of experience, ARBENTIA has established itself as one of Microsoft’s leading partners in Spain in the field of business applications, combining experience in ERP, CRM and data solutions with in-depth knowledge of sectors such as industry, distribution, services and automotive. Its diversified geographical presence and commitment to 100% organic growth reinforce a unique positioning in a market marked by concentration processes and inorganic operations.
Looking to 2026, the roadmap involves continuing to deepen the industries where it already has critical mass, expanding solutions on the installed base and industrializing the combination of business cloud, data and Artificial Intelligence (including agentic AI) both in its own operation and in that of its clients. In a context where the digital maturity of the Spanish mid-market is accelerating and AI is beginning to form part of the structural layer of information systems, ARBENTIA aspires to convert its status as a “zero customer” into a clear competitive advantage within the Microsoft ecosystem.
