Lightyear Capital announced a strategic investment in Corestream. Corestream is a voluntary benefits and employee savings technology platform focused on serving employers, employees, brokers, carriers, and partners.
Founded in 2006, Corestream automates the full voluntary benefits lifecycle. Its platform supports selection, enrollment, billing, reconciliation, and ongoing administration through integrations with HRIS, payroll, and carrier systems.
Corestream serves more than 6 million employees. The company also reconciled more than $500 million in payroll premiums in 2025.
Lightyear’s investment will support continued product innovation, technology infrastructure development, and partner connectivity. The goal is to help Corestream deliver a more connected benefits experience and make it easier for employees to access, understand, and enroll in voluntary benefits.
Corestream said the investment will also help the company move beyond transactional benefits distribution. The company plans to build longer-term relationships with employees by helping them understand their options and make more confident benefits decisions.
LLR Partners, Corestream’s existing investor, will continue supporting the company alongside Lightyear and Corestream’s management team. Together, the investors plan to help accelerate Corestream’s next phase of growth.
Davis Polk & Wardwell served as legal counsel to Lightyear. TripleTree served as Corestream’s exclusive financial advisor, and Dechert served as legal counsel to Corestream.
Terms of the transaction were not disclosed.
KEY QUOTES:
“We are excited to partner with Neil and the Corestream team. 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. Lightyear’s experience across healthcare, insurance, brokerage, fintech, payments and enterprise technology aligns directly with Corestream’s opportunity to simplify a complex ecosystem and scale a market-leading platform.”
Mark Vassallo, Managing Partner at Lightyear Capital
“In Lightyear, we found a partner that understands the complexity of our market and the scale of the opportunity ahead. 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. We also want to create better outcomes for every participant in the ecosystem, from employers and employees to brokers, carriers and partners. If every stakeholder wins, the ecosystem scales. I am excited to combine Lightyear’s deep domain expertise with the continued partnership and support of LLR Partners. Having two incredible investors by our side gives us a powerful platform to take Corestream to the next level.”
Neil Vaswani, Co-Founder and CEO of Corestream
“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. The Company has the technology, relationships and management team to take the category to the next level. We are excited to support Corestream as it continues to invest in innovation and expand its leadership position.”
Michael Langer, Partner at Lightyear Capital
“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 better understand and access the benefits that matter most to them. We are excited to continue supporting Corestream alongside Lightyear as they further strengthen the Company’s leadership position.”
Sasank Aleti, Partner at LLR Partners
