What does Mare + Co. do?

Mare + Co. gives small and midsize businesses the financial leadership of a seasoned CFO without the full-time hire. That means fractional CFO work, revenue strategy, financial modeling, dashboards, and benchmarking, plus hands-on AI and financial literacy training so your team can use the numbers. Founder Tina Sawtelle has 25 years as a CFO and CEO.

Who is Mare + Co. for?

Owner-led and founder-led businesses, typically $1 million to $20 million in revenue, that have outgrown bookkeeping alone but are not ready for a full-time CFO. We work often with restaurants, live entertainment and arts organizations, professional services, higher education and small manufacturers amongst other businesses.

Where is Mare + Co. located?

Mare + Co. is based in Dover, New Hampshire. We serve clients across New England and into greater New York, work remotely with businesses anywhere in the United States, and travel to clients in other states. The Virtual CFO Founding Program starts with owner-run businesses in New Hampshire and New York.

What is the difference between a fractional CFO and a virtual CFO at Mare + Co.?

Fractional CFO is a monthly retainer with Tina as your part-time finance lead, working with your whole team. The Virtual CFO, launching January 1, 2027, is a lower-cost subscription for small businesses: a free diagnostic, a Financial Clarity Report, and a monthly read on what to do next.
