About Us
Making Business Planning Accessible for Small Businesses and SMEs
Square One Advisors is a small team of passionate business professionals with combined decades of experience in financial markets.
Having worked for some of the world’s top business services organizations, we wanted to create a company that would allow us to provide the same services as the Big 4, but more affordably, more targeted, more focused, and more client-centric.
We realized that for any business to succeed, a quality business plan was essential. However, when completed by a big company, the deliverables often fall short, offering a generic, high-level report that lacks personalization.
We bring deep knowledge, experience, and expertise in many industry niches and specialties. We can really help companies add value in a targeted, flexible, and significantly more affordable way than larger advisor firms.
Our singular focus is your success at any stage of business maturity. Whether you are launching a new venture, selling the business, restructuring, or preparing for an equity raise, a Square One business plan provides you with the insight and strategy you need to achieve your goals.
