Why I’m pivoting my budget from a b2b lead gen agency to automation.

Last year we spent $50k on a b2b lead gen agency and the ROI was just fine. It wasn't life-changing. I’ve realized that the special sauce these agencies have is just a combination of data scraping and automated sequences. This year, I’m moving that budget into building a more robust internal stack. Has anyone else made the jump from agency-managed to platform-managed lead gen? What were the biggest hurdles?
