“Before Volca, referrals at Zoom Drain were tracked manually, with paper checks and missed payments. It was clunky and inefficient. Volca changed everything—automating the process, expanding it beyond B2B, and letting technicians enroll customers on-site. Now every customer becomes a referral partner, and the program runs hands-free. In just one month, referrals more than doubled and drove over 30% of revenue. Volca didn’t just improve referrals—it made them a growth engine.”
