HubSpot has announced its acquisition of Cacheflow, a startup specializing in tools for closing software sales. This move aims to enhance HubSpot’s Commerce Hub suite, particularly in subscription billing management and configure, price, quote (CPQ) tools. Cacheflow, founded in 2021, will operate as a subsidiary, helping businesses automate revenue management. The acquisition follows Cacheflow's $16 million fundraising and positions HubSpot for growth in the B2B software market. HubSpot shares rose 1.3% post-announcement, reflecting investor optimism about the deal's potential.
