From compliance filings to identifying investors to preparing for a bond sale, we help our issuer-partners lower their costs and stand out in a very crowded bond market.
"More and more of the bond market is moving online every day, and it's incredible to see issuers adopt new, digital-first strategies to advance their departments."
Colin MacNaught
CEO & Co-Founder

Led by Experience. Driven by Results.

BondLink CEO Colin MacNaught spent seven years issuing nearly $25 billion in bonds on behalf of the Commonwealth of Massachusetts. During his tenure he was struck by the limited technological resources available to him. Investor outreach, financial disclosure, and analytics were simply too time-consuming and too inefficient. After leaving the Treasurer’s office in 2015, Colin decided to found a company that would provide issuers with the tools they need and the edge they seek. He joined up with Carl Query, a successful entrepreneur with a deep understanding of the tech startup space, Carl was the perfect complement to Colin’s municipal market acumen. BondLink was born.

Carl and a team of engineers began to build out a turnkey investor relations website to Colin’s specifications, creating the very tool he dreamed of during his years as an issuer. In January 2018, BondLink completed a Series A financing of $10 million, led by Franklin Templeton, one of the single largest holders of muni bonds. Intercontinental Exchange, a global provider of data, technology and market infrastructure, then made a strategic investment in BondLink for their Series B. BondLink continued to grow, building a client list that includes the City of Chicago, the University of Texas and the State of California, some of the biggest issuers of municipal bonds in the United States. Since 2018, BondLink clients have issued more than $115 billion in bonds, and our client investor relation sites have been visited more than 2 million times.
