Casey Hill named several competitors that customers have migrated away from when joining ActiveCampaign, including Mailchimp, Brevo, and ConvertKit. These were cited as examples used in voice-of-customer LinkedIn campaigns, where ActiveCampaign asks customers to post about why they switched. No financial or operational metrics about any competitor were provided by Hill, and none of the competitor names carry company-confirmed data.
Hill also noted that when identifying podcast guesting opportunities, he looks at where executives from Mailchimp and HubSpot have appeared as guests, using their podcast footprint as a map for relevant shows. This was a tactical observation, not a statement about those companies' performance.
