Early-stage AI and deep tech companies face complex financial decisions long before they can justify a full-time CFO. Nelson CFO provides board-level financial leadership to companies navigating growth, capital planning, and investor expectations.

Expertise Without the Full-Time Overhead
Most early-stage technology companies reach a point where financial decisions become too complex to manage alone.
Fundraising, runway planning, and investor reporting all require experienced financial leadership.
Yet hiring a full-time CFO too early can introduce cost and structure before the company is ready.
A fractional CFO provides the same senior-level perspective on a part-time basis — helping founders build financial models, manage runway, prepare for fundraising, and establish the reporting discipline expected by investors and boards.
The goal is simple: give the company the financial structure it needs to scale, without introducing executive overhead before the business requires it.

About Jason Nelson
I founded Nelson CFO to provide early-stage technology companies with the financial leadership they need before they are ready to hire a full-time CFO. Many founders build remarkable technology but lack the financial structure required to support disciplined growth and investor expectations.
With more than 20 years of experience in the financial industry and an MBA from Columbia Business School, I work with founders to build financial models, plan capital requirements, and bring clarity to financial decision-making as their companies grow.
I am also an advisor to Loyal VC, a global venture fund investing in early-stage technology companies.
Through Nelson CFO, I support companies building AI and deep technology by helping founders strengthen their financial foundations and prepare their businesses for the increasing financial complexity that comes with growth.

Is It Time to Bring in a Fractional CFO?
Many early-stage technology companies reach a point where financial decisions become too complex to manage informally. A fractional CFO provides the financial structure and guidance needed to navigate this stage of growth.
Founders often begin exploring fractional CFO support when:
• You are preparing for an investor fundraising round and need credible financial models and forecasts
• Your financial model no longer reflects the realities of the business
• Hiring decisions are significantly affecting burn rate and runway
• Investors or advisors are asking for clearer financial reporting and forward planning
• Strategic decisions around pricing, growth, or capital allocation are becoming more complex
• You need experienced financial leadership but are not ready to hire a full-time CFO
A fractional CFO provides the financial structure, discipline, and insight needed to navigate this stage of growth with confidence.
If these challenges sound familiar, a conversation can help clarify the right financial structure for the next stage of growth.
