Spark· New York, New York, United States
Spark is the platform behind independent Medicare brokers — giving them the technology, services, and community to become true advocates for their clients.Since 2019, we've grown from 200 brokers to more than 10,000. We've driven 250,000 enrollments in 2025 and we're building toward 1 million by 2027. We're one of the fastest-growing Medicare NMAs in the country.The US healthcare system is the most expensive in the world, and one of the worst at helping people navigate it. The brokers on our platform are changing that — one enrollment at a time. For the people who build Spark: this is not a mature company running a playbook. You own real outcomes, hold a high bar, and work on something where the impact is measurable. If that's what you're looking for, we'd love to talk.
