Experience with Leading Technology Companies

<blockquote>
&quot;Being ranked among the Top 20 in Runet Rating confirms that Doubletapp&#39;s AI expertise is recognized by the market. We started working with machine learning and artificial intelligence technologies long before generative AI became mainstream, and today we help companies not only implement LLMs but also adapt them to solve specific business challenges.

Training and fine-tuning LLMs always involves working with the customer&#39;s data, infrastructure, and business processes. Success is measured not only by model quality but also by how seamlessly the model integrates into existing products and delivers measurable business value. That is exactly where we focus our efforts in every project.

Recognition in the ranking is certainly rewarding, but what matters most to us is our clients&#39; trust and the successful projects that move into production and continue evolving alongside their businesses.&quot;
