ABOUT AJAX SYSTEM
Ajax Systems was founded in 2011 in Kyiv by Oleksandr Konotopskyi, with the ambition of creating a reliable wireless security system positioned between low-cost Chinese products and high-end Western brands. In 2015, the company received its first investment of $1 million from the SMRK fund. Four years later, in 2019, Horizon Capital injected $10 million, enabling Ajax to grow to around 800 employees and produce 200,000 devices a month, up from 100,000 four years earlier.
In 2022, despite a difficult context marked by the invasion of Ukraine, Ajax doubled its production capacity, opened a factory in Turkey and saw its sales increase by 35%. The team now numbers 2,620 employees, including over 600 R&D engineers, and the range exceeds 70 products.
Today, in 2025, Ajax employs around 1,940 people and achieves estimated sales of $665 million, with headcount growth of almost 26% on the previous year. In the space of fourteen years, Ajax has grown from a Ukrainian start-up to a world leader in wireless security systems, present in 169 countries and recognized for its innovation and reliability.
