About Caribou

Caribou is building the engagement infrastructure for the home care workforce and the agentic layer for home care operations.

The home care workforce is the largest and fastest-growing workforce in America. We need more caregivers, more durable home care businesses, and higher-quality care delivered in the home.

The global population is aging, and the need for home care is growing each year. Unfortunately, at a time when care is needed more than ever, the home care industry is facing a crisis a shortage of care workers.

At Caribou, we're on a mission to solve the caregiver crisis. When caregivers feel valued, recognized, and financially secure, they stay longer, deliver better care, and strengthen our communities.

Our platform helps care organizations attract, engage, and retain staff through data-driven recognition, rewards, and coordination tools that make caregivers' lives better and agencies more successful. On average, our customers grow their staff by 25% in year one and reduce turnover dramatically.

Now, we're expanding what's possible. Caribou is deploying AI-powered agentic systems that work alongside agency coordinators handling routine coordination, outreach, and administrative workflows so that staff can spend more time on what matters most: building and maintaining relationships with the caregivers and patients they serve. Better agency operations lead to a more stable caregiver workforce.

Caribou was recently recognized as one of The Globe and Mail's Top Growing Companies #10 in technology and we're just getting started. Join us as we transform how care organizations recognize and retain the people who make care possible.
