Agency Services


In 2009, Marcus Sheridan started writing his thoughts on Business, Sales, and Marketing on a simple blog he named “The Sales Lion.”

As The Sales Lion audience grew, more and more companies started asking Marcus to help them achieve success with Inbound and Content Marketing. By 2012, the little blog had become a small business with a global reach. Over the next five years TSL would work with hundreds of businesses and brands in an effort to help them reach their sales and marketing potential.

Early 2018 brought major growth and new opportunities for TSL as Marcus merged the company with IMPACT, HubSpot’s 2017 Partner of the Year. Marcus is now co-owner of this thriving 50+ person agency located in Wallingford, Connecticut. With this move, IMPACT has become the only agency in the Inbound space to provide such a comprehensive offering of educational training, conferences, and support.
