Our Story
In 2007, our co-founders, Michael and Shirin, recognized the limitations of relying on a single firm’s one-size-fits-all solutions when approaching complex problems. To truly serve their clients and achieve digital transformation, they knew they needed to forge partnerships with a diverse range of service providers across various technology platforms.
By 2010, our dedication and expertise had earned the trust of larger firms we had previously worked with. They entrusted us with significant projects that propelled our business growth and scalability.
In 2020, we found ourselves enabling remote work solutions that surpassed the quality and efficiency of traditional office setups.
By 2023, we realized that our name, ColoAdvisor, no longer reflected our comprehensive expertise in cloud services, CCaaS, connectivity, collaboration, unified communication, security, telecom, and IT services. Consequently, we underwent a rebranding process, adopting the name “515 Engine.”
Today, at 515 Engine, our primary focus lies in assisting organizations with their unique digital transformation journeys. We firmly believe that in an era marked by numerous constraints imposed on businesses, there is no one-size-fits-all best practice. We strive to tailor our solutions to the specific needs and circumstances of our clients.
