Opportunities

The broad range of sleep-health products and services creates a plethora of entry points and investment theses for private equity firms to consider, ranging from potential roll- up strategies (e.g., mattresses and bedding) to building a holistic portfolio of sleep-health solutions (e.g., sleep labs, consultants, and monitoring tools).

Brand credibility is table stakes, as consumers are not looking for gimmicks but rather demanding products and services with proven results. The bedrock of brand credibility is a clear reason to believe (e.g., specific mattress foam, active ingredients, doctors’ endorsements) the company’s product will deliver on the promised benefit. Second, the business needs to have a clear point of differentiation to separate it from the abundance of competitors in the space.

Finally, the business needs to prove it has legs beyond one core hero product or service to ensure that there is a pathway to sustain long- term growth. The underlying implication is that sleep health is an attractive place for private equity investment, but the investment opportunities need to be filtered through these three lenses to ensure they have consumer permission to scale long term, according to McKinsey report titled “Investing in the growing sleep-health economy”.
