CaaS can also be referred to as a CTO that is outsourced or hired from a third party. In such cases, the costs of hiring CTO services are reduced, along with many other benefits. Companies often tend to outsource a virtual CTO, because they have experience working in diverse industries. A CaaS is also responsible for looking at the research and development since it helps to prepare a better framework for the company's technical aspect. A CaaS can also be a part of the in-house team, which subsequently increases the expense. A CaaS is also responsible for strategizing trendy ideas that fit the brand's needs.
