Castanet
Mac Martine founded Castanet, a LinkedIn outreach automation tool, in August 2018. The tool catered to consultants, freelancers, and lead generation agencies, growing to $61,000 MRR before being sold in February 2021. This success followed several failed attempts in SaaS development. Martine’s approach involved extensive market research, networking, and continuous iteration based on customer feedback, which proved crucial in achieving Castanet’s eventual success.
