Mike Monaghan is the owner of Total Hearth, an e-commerce parts business for wood stoves and fireplaces that grew from 3 sheets of ceramic glass into a $2.5 million brand. He explains why he puts his phone number front and centre, how asking for a photo of the stove’s plate stops wrong part orders, and why he uses AI as a watchdog but never lets go of the wheel. He also shares how he plans to smooth a brutal seasonal cash roller coaster with RV, pool and HVAC lines. Listen to hear how a niche parts brand keeps growing.
