Switched from HubSpot to Keap about 18 months ago - it’s been solid for agency work. White labeling’s decent (not perfect), and multi-client management through their partner program works well. What sold us was their automation builder - way more intuitive than other platforms we tested. Pricing fits smaller clients better than HubSpot, and we can resell without jumping through sales hoops. SOC2 compliance is handled. Integrates with most tools we need, though complex setups sometimes need Zapier. Heads up on the learning curve when migrating client campaigns. Took us two months to fully transition everything, but the workflow efficiency boost was worth it. Support team actually responds fast - nice change from other platforms.
