Financial Reporter

With over 10 years of selling technology to hundreds of SMB and Enterprise companies across multiple sectors, I have begun to wrap my head around the art of sales. 

I've been a part of 3 exits - one as a founder and two as a founding sales lead. I'm a people person, who loves to connect, lead, share experiences, coach, strategize and implement. I enjoy writing and sharing ideas and look to work with sales leaders and founders who are creating the impossible.

I have built and scaled full cycle business units and as an individual contributor, I have signed large enterprise deals with over 500 companies. 

I take that knowledge into Whistle, a revenue generation company supports over 150 customers through best practice sales and marketing. We offer the best people, processes and full transparency and are proud to work with leading B2B brands worldwide. To learn more, head to www.whistle.ltd
