Founded2021

Cylinder Health is a healthcare technology company focused on streamlining and automating the burdensome prior authorization process for medical providers. Their platform is designed to handle the end-to-end workflow, from initial eligibility checks and submission of requests to tracking their status. By leveraging technology, Cylinder Health aims to reduce administrative overhead, minimize delays in patient care, and allow healthcare professionals to dedicate more time to patients rather than paperwork. The company was founded in 2022 to address a significant pain point in the US healthcare system, making it easier and faster for patients to get the care they need.

Where is Cylinder's Headquarters?

HQ Function

Serves as the official registered address and a central point for administrative and strategic operations. Given the Private Mailbox (PMB) nature of the address, day-to-day operations are likely managed through a distributed or remote-first team structure.

Notable Features:

The listed headquarters address is a Private Mailbox (PMB), indicating a flexible operational model rather than a traditional office building with specific architectural features. This approach is common for modern tech startups prioritizing agility and remote talent.

Work Culture:

Cylinder Health likely fosters a dynamic, innovative, and mission-driven work culture typical of tech startups. There is likely a strong emphasis on collaboration, agility, problem-solving, and leveraging technology to impact healthcare positively. A remote-first or hybrid model is probable, promoting work-life balance and access to a broader talent pool.

HQ Significance:

The San Francisco Bay Area registration places Cylinder Health in a leading global hub for technology, innovation, and venture capital. This provides strategic advantages in terms of talent acquisition, investment opportunities, and networking within the health-tech ecosystem.

Values Reflected in HQ: The use of a PMB and likely remote/hybrid operations reflects values such as operational efficiency, resourcefulness, flexibility, and a focus on talent over geographical constraints.

Location:

Cylinder Health is primarily focused on the U.S. healthcare market. Its operational model supports a geographically distributed team, with employees and collaborators potentially working from various locations across the United States. The company's services are delivered digitally, enabling them to serve healthcare providers nationwide. While not having physical international offices, their technology-driven approach allows for scalable operations.
