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. He worked on the testing and design of Micro Air Vehicles used in surveillance and Battle Damage Assessment. After graduation, he moved back home 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 Graduate Consulting Club (HGCC) while he was earning a Masters in Finance from Harvard University. What will eventually become Sigma Ridge, started as a spinoff of the HGCC. Since then, he has consulted or been employed by startups and billion dollar organizations and has managed operations as large as 13 different countries with 125 direct reports. This diverse background has enabled him to gather abundant experience, which has made Sigma Ridge so successful

"Most SMBs (Small and Medium Size Business) are created with a service or product that has enormous potential, but only under the right business strategy and execution. SMB’s CEOs and Business Owners are usually very smart and driven: engineers, inventors, business owners and leaders, but they often lack the necessary knowledge to take their business to the next level. This business expertise is hard and expensive to find. And, while experience can help, the right background and education can be far more effective and efficient in developing and executing a growth, or turnaround strategy.

Most SMBs lack a formal and measurable business strategy for the short and long term. And, nearly all of them could use some guidance with their strategic, tactical and marketing initiatives. This is where Sigma Ridge thrives: Complementing the potential of our select clients to take their business to the next level."

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!
