OpenYield closes $6M Series A led by LeveL Markets to bring equity-style trading to bonds
What's the deal? OpenYieldDealroom has a profile for this one. Try Dealroom →, a bond marketplace that lets participants trade fixed income the way they trade equities — with firm prices in a live order book — has closed a $6M Series A led by LeveL MarketsDealroom has a profile for this one. Try Dealroom →. Draper Associates, Canapi VenturesDealroom has a profile for this one. Try Dealroom →, and Clocktower Ventures also participated.
The round comes bundled with a commercial partnership. LeveL Markets, an institutional equities venue backed by Nasdaq, BlackRock, CitiDealroom has a profile for this one. Try Dealroom →, and Bank of AmericaDealroom has a profile for this one. Try Dealroom →, will integrate OpenYield into its platform. That gives LeveL's institutional clients direct access to OpenYield's bond liquidity through the same connections they already use to trade stocks.
Founded in 2023, OpenYield is registered as an alternative trading system (ATS) and runs an all-to-all venue where any participant can trade with any other. It has executed nearly $2B in volume across corporate bonds, municipal bonds, and US Treasurys, signing more than 60 institutional clients representing over $5T in assets under management.
Why now? The $150T fixed-income market still runs largely on infrastructure built before modern automation. But dealers have developed algorithms that can quote bonds in milliseconds — creating the conditions for an equity-style order book to work in fixed income for the first time.
"Most of the technology that powers the bond market was designed for a world where a human picked up the phone," said Jonathan Birnbaum, founder and chief executive officer. "That world is gone."
Birnbaum ran fixed-income execution at Bridgewater Associates and was chief operating officer of US credit trading at Morgan Stanley before founding OpenYield. Co-founder and chief technology officer Hilton Lipschitz has built trading systems for hedge funds managing billions in fixed-income assets.
What could go wrong? Bond market incumbents are deeply entrenched, and OpenYield faces established electronic platforms like MarketAxess and Tradeweb that already serve institutional clients. Convincing large dealers and asset managers to shift meaningful volume to a young ATS is a formidable task, even with LeveL's distribution reach.
Liquidity begets liquidity — and at nearly $2B in total volume, OpenYield is still a speck in a $150T market.
The signal: Having an equity-venue operator lead the round — rather than a typical fintech VC — underscores that the convergence of equity and fixed-income market structure is becoming an active infrastructure bet, not just a thesis. Draper Associates' involvement alongside specialist investors like Canapi Ventures and Clocktower Technology VenturesDealroom has a profile for this one. Try Dealroom → suggests appetite across generalist and sector-focused funds for early-stage plays that tackle the $150T bond market's outdated plumbing.
