Retrieval-Augmented Generation (RAG) is a technology that is changing the way companies approach the use of artificial intelligence. By combining large language models with current, verified data, RAG enables faster, more accurate, and fact-based decision-making. It is no surprise that more and more organizations - from FoodTech to fintech to the public sector - are looking for partners capable of creating enterprise-level RAG solutions.

Top RAG Development Companies: Who Leads the Market in 2025?
Retrieval-Augmented Generation (RAG) is reshaping how organizations use artificial intelligence. While traditional AI models often lack access to up-to-date and verified information, RAG bridges this gap - enabling leaders to make faster, more reliable, and fact-based decisions. For C-level executives, this means not only eliminating inefficiencies but also unlocking new revenue opportunities and reducing risks tied to inaccurate or outdated data.
On this blog, we regularly share our experiences and analyses related to RAG, and our previous publications have been met with great interest from managers and business owners. Continuing this series, we decided to prepare a ranking of companies that stand out on the market in 2025 as the most reliable partners in the area of RAG development.
This ranking was created based on key criteria important from a leadership perspective: documented production implementations, domain specialization, security and compliance practices, as well as experience in working with open and commercial AI models. We have included both global players and European software houses that have proven their effectiveness in real-world projects.
1. Railwaymen - Pioneering RAG Development with FoodTech Roots
Placing Railwaymen at the top of this ranking is not an act of self-promotion - it is the result of recognizing the measurable value we deliver through RAG-based solutions. Unlike firms that limit themselves to proof-of-concept pilots, we focus on implementations that directly address business challenges and bring visible ROI for decision-makers.
We are a software house with over 15 years of experience in implementing projects for many industries: from FinTech and retail, through construction, to social and FoodTech. Regardless of the sector, our projects have one thing in common - we always start by understanding the real needs of the business, and only then do we select the technologies that can best meet them.
One of our flagship initiatives is the AI Assistant for FoodTech - a RAG-based solution co-created with restaurateurs in the GCC region. It integrates data from POS, e-Wallet, and delivery platforms into actionable insights. Managers can ask simple questions like “Which product had the highest margin last month?” and immediately approve an action such as launching a promotion or updating the menu. This isn’t a concept on paper — it’s a working demo that shows how RAG can transform everyday decision-making.
Although FoodTech is one of the areas where RAG shows its strength, its application goes much further. As we wrote in our last article, RAG works well wherever quick access to verified data is important: in finance, retail, or infrastructure management. This universal approach makes Railwaymen a partner ready to support businesses from many sectors.
What truly sets us apart, however, is our focus on building solutions that respond to real market needs. This is why we launched the FoodTech Institute - an initiative that engages business owners and managers to co-create future-ready AI solutions. Instead of building technological “fireworks” with no business impact, we design tools shaped by real-world input. For participants, joining the Institute can be a game changer: an opportunity to influence product development, gain early access to innovations, and be part of a community shaping the future of FoodTech.
For participants in the initiative, joining the FoodTech Institute can be a game changer - it is an opportunity to co-create modern AI standards, gain a competitive advantage, and be part of a community that is truly shaping the future of the industry.

Which RAG development partner is right for you?
A ranking of ten companies that stand out in the field of RAG development in 2025 shows how diverse the approach to this technology is today. Some providers focus on ready-made SaaS platforms that can be implemented almost immediately, others focus on strategic consulting and integration in large organizations, and still others focus on solutions tailored to specific industries.
For decision makers, the key question is not so much “which company is the best?” as “which company best addresses my company's challenges?” It is precisely these different models of cooperation and specializations that make each of the companies described a valuable choice in a different context.
At the same time, it is worth noting that partners who not only implement technologies but also co-create them with customers and respond to real business needs are gaining increasing importance in the market. This approach is beginning to set new standards - this is particularly evident in the activities of software companies that develop their own research initiatives and RAG-based products.
