4 Day Week operates as a marketplace connecting job seekers with employers looking to fill positions that offer a four-day workweek. This job board acts as a centralized platform where companies can post job listings and job seekers can apply directly through them. The marketplace model is pivotal for this business as it enables them to bring together demand (job seekers) and supply (companies offering four-day workweeks). This model is efficient and scalable because it focuses on creating a platform that can facilitate interactions and transactions between employers and potential employees. Since Phil McParlane is also utilizing a subscription model where companies pay to have their job listings featured, it maximizes the company's visibility to potential applicants and monetizes the platform effectively.

In addition to operating the job board, the narrative suggests potential offering of consulting services focusing on transitioning companies to a four-day workweek model. Phil McParlane discusses the broader industry trends and the value of autonomous work. Consulting services would likely involve providing expertise, strategies, and potentially conducting workshops or providing materials to aid companies in understanding and implementing the four-day workweek. The consulting aspect allows the business not just to provide a job marketplace but to also be seen as thought leaders and experts in the cultural transition towards more flexible work arrangements. This adds another dimension to the business model, creating multiple revenue streams and further establishing authority in the niche of work-life balance and new work norms.
