The
Bond Market Powering Retail

Making it easy for broker-dealers, advisors and asset managers to offer attractive bond investing solutions to retail clients.

Simplifying
Fixed Income Investing

Buying bonds can be as easy as buying stocks. That’s why we’ve built a modern marketplace that makes it simple for institutions to provide their retail clients with the income, growth and reliability of fixed income.

Unique Liquidity

We’re algo dealer-enabled, eliminating “last look” privileges and requiring dealers to offer only firm, live quotes. We’re also simplifying bond selection by offering investors a curated set of the most liquid corporates, municipals and Treasurys. With OpenYield, what investors see is what they get.

No Minimums

There are no minimum order sizes on our marketplace, enabling you to satisfy the needs of all your retail clients, whether they want to purchase one bond or hundreds.

Flexible Technology

Our flexible APIs, modern tech stack and data services – including price history, yields and cash flows – give you everything you need to enter the bond market or enhance your current offerings.

A Low Cost Marketplace

With an aggressive pricing schedule and the ability to optimize post-trade fees through batch settlement, OpenYield is on a mission to minimize costs for small tickets.

In Pursuit of Innovation

Our team has successfully built and scaled both retail and institutional fixed income investing platforms in the past. Today, we’re combining modern technology with an innovative market model to deliver the industry’s biggest transformation yet.
