Who are we?
Co Yazılım is a technology company founded to close software gaps in the enterprise market, building scalable and secure software solutions.
Our Story
Co Yazılım was founded by a team who spotted a critical gap in the enterprise market. Existing CRM and communication solutions were either too expensive or too basic for small businesses.
We took a different approach: building enterprise-quality software that runs as both SaaS and on-premise. This gives our customers both flexibility and cost advantage.
Today, our three core products answer enterprise needs across different segments: Co CRM for 360° customer relationships, Co WebBuilder for web presence, and Co SIP Platform for enterprise communication.
Every product we build starts from real user needs and is tested to enterprise standards. GDPR, KVKK and CCPA compliance was built into the architecture from day one.
