Senior marketing expertise is critical for startups and small businesses to succeed but can be too expensive to hire full-time. An increasingly popular alternative is an on-demand or part-time Chief Marketing Officer (CMO) who can develop an integrated long-term marketing strategy and oversee its implementation at a fraction of the cost of full-time hiring or an agency. The on-demand CMO model provides flexible expert support tailored to the business's specific needs on an as-needed basis.
