about The founder

Sales and Marketing Consultant

Alexander Sierra has a diverse background. He started his career at an early age, in Sales. He continued to work while going to school until he obtained his Bachelor in Aerospace Engineering from the University of Florida. Alex landed a job at the university doing research for NASA and the U.S. Military working on testing and design of Micro Air Vehicles. He then moved to Boston where he worked at an MIT startup where he was quickly promoted to sales and operations manager. He then obtained his MBA at the University of Massachusetts -Dartmouth-, while working as a manufacturing Industry Consultant with the world’s largest Machine Manufacturer. In 2010 he joined the Harvard University Consulting Club while earning a Masters in Finance from Harvard University.
This diverse background has enabled him to gather a lot of experience, which has made him successful in his consulting career.

NASA Researcher
Harvard Business School

"We see a gap for Medium and Small businesses that need Business Strategy, Tactical and Marketing guidance. We find that most businesses are born with a service or product that has a huge potential, under the right business strategy and execution. This business expertise is hard to find, and while experience can help, the right background and education can be far more effective and efficient. In most cases, this type of Business and Marketing expertise is not known by Medium and Small Business owners and CEOs. These individuals are usually very smart and driven: engineers, inventors, business owners and leaders, but they lack the necessary knowledge to take their business to the next level. That is the gap where we are a perfect fit for our clients."

Team of experts combining marketing, management, and consulting

Who we are

We are a team of individuals with over a hundred years of combined marketing, management and consulting experience. We have helped many of our clients increase revenue, profits, and to obtain a competitive advantage in their market.

We are a selective team and unfortunately we do not take all client engagements. We only work with organizations where we truly believe we can make a difference. We work by doing a free exploratory call or site visit. We, then make a decision on whether or not to take on a project or engagement. If we cannot help you, we can usually recommend someone that can.

We look forward to working with you and your team!
