About Ledger Investing

Ledger Investing is a Y Combinator backed insure-tech startup that is transforming the way insurance risks are financed. Today, Ledger is an online marketplace connecting insurance risk to capital, focusing on securitization. Insurance risk originators are able to source capital more efficiently vs. the traditional value-chain. Capital providers gain access to an asset class that is highly diversified vs. most asset classes. Insurance securitization has quickly grown to be a $100 billion market but is limited in scope due to opacity and complexity. Ledger is expanding this market to $1 trillion by building a seamless data pipeline from the policyholder to the capital markets, enabling transparency, and bringing best-in-class analytics and real-time insights to the table. Our recent $75 million Series B round of investment funding has set us up for exponential growth. We are on our way to disrupting the industry by serving as an unparalleled, advantageous marketplace for virtually all types of insurance risks and capital, including traditional reinsurers, institutional investors, and accredited investors.
