Our History

Millennium S.I. was founded in 1987 to provide the beauty and wellness industries with forward-thinking, powerful management software and vital tools. It began more than three decades ago when John Harms built a company based on revolutionary technology, outstanding support, and more importantly, a strong passion to educate salon and spa owners on how to sustain success.

Meevo was built on a vision to not only help salons better manage their staff, clients, and inventory, but to ultimately help owners like you make the right decisions and continuously grow their business.

Today, Millennium S.I.'s software is utilized in thousands of salons and spas in over 36 countries and processes billions of transaction per year.
