Corestream Receives Investment From Lightyear Capital

The company will use the funding to expand its operations and support product development.

Corestream provides a single platform that simplifies the entire voluntary benefits process, from enrollment to billing, reconciliation, and ongoing administration. The platform integrates with HR, payroll, and insurance systems, serves more than 6 million employees, and processes over $500 million in payroll premiums in 2025.

Michael Langer, Partner at Lightyear, said, “Voluntary benefits have become an increasingly important part of the modern employee value proposition, but the market remains fragmented and difficult to navigate. Corestream is the only privately owned, pure-play voluntary benefits technology company to achieve this level of scale.

“It has been a privilege to support Neil and the Corestream team and we are grateful for their partnership. Since LLR’s investment in 2019, Corestream has grown significantly and established itself as a market leader, enabling employers to offer voluntary benefits at scale and employees to understand better and access the benefits that matter most to them,” said Sasank Aleti, Partner at LLR.

“We are excited to partner with Neil and the Corestream team,” said Mark Vassallo, Managing Partner at Lightyear. “Corestream has built a differentiated platform in a category that continues to grow as employers seek better ways to support employees, expand benefits choice and address gaps in core insurance coverage.

“In Lightyear, we found a partner that understands the complexity of our market and the scale of the opportunity ahead,” said Neil Vaswani, Co-Founder and Chief Executive Officer of Corestream. “This investment is about much more than capital. It is a strategic investment in our product, our platform, our people and our vision for what voluntary benefits can become. Our ambition is to move beyond transactional benefits distribution and build a trusted, long-term relationship with employees. We want to help them understand their options, make more confident decisions and access benefits that are relevant to their lives.
