Crossbeam, a collaborative data platform that allows companies to find overlapping customers and prospects with their partners, has raised $12.5M in a Series A financing led by FirstMark Capital with participation from its existing investors First Round Capital, Uncork Capital, and Slack Fund.

The company also brought on HubSpot Ventures and Salesforce Ventures as new investors.

“These iconic B2B brands are not only key tech integrations for our platform, but also partnership supernodes whose partner ecosystems — which encompass thousands of partner companies — represent the magnitude of the opportunity at hand,” said CEO and Co-Founder of Crossbeam Bob Moore in a blog post on the company’s website.

With this new funding, Crossbeam will continue to grow its network and customer value.
