Nicole Sithithavorn’s career turned at a deli counter. She was 21, not raised around business, the daughter of a security guard and a data-processing worker, and the first person in her immediate family to attend college. She was working two jobs to remain there. Then a conversation with a construction-company owner led to consumer financing, which led to operations, which eventually led back to school for accounting. It is the sort of origin story that makes career planners nervous: consequential, accidental, and impossible to reproduce with a worksheet.
The accidental opening did not produce an accidental career. Sithithavorn became an assistant controller, spent time at a venture capital firm, and returned to a home-improvement business when the chance came to buy in. As an owner and the company’s CFO and COO, she sat on both sides of the spreadsheet. A forecast might say one thing. The people, processes, customers, and cash account might answer with another.
She says the company reached $45 million in annual revenue with no debt before she and her partners sold it in 2021. The business, Remodel USA, joined Renovo Home Partners in a transaction announced early that year. Sithithavorn stayed for two more years. By the time she left, she had learned how to grow an operating company, how to prepare one for sale, and how peculiar it feels to remain after ownership has changed hands.
A CFO with one shoe on the factory floor
Finance is often treated as a room where the rest of the company’s decisions arrive to be translated into tidy columns. Sithithavorn’s experience ran in the opposite direction. Serving as both CFO and COO meant the columns walked back out of the room. Compensation became retention. A delivery bottleneck became cash pressure. A manager’s rough promotion surfaced later in the profit and loss statement. The work was less about admiring a model than using it to decide what happened next.
“Partners need to have trust, they need to have kind of an authentic relationship that's built on that trust.”Nicole Sithithavorn, Thriving Through podcast
That operating range became the premise of YC Partners. Sithithavorn did not want to remain a full-time corporate CFO. She wanted to bring the strategic finance available in a more mature, lower-middle-market company to smaller businesses that had real complexity but no career CFO at the table. The idea sounded personally useful and professionally fulfilling. In December 2023, she decided to go for it.
Two hundred connections and zero buyers
The first surprise was almost comic in its precision. Sithithavorn announced the new firm on LinkedIn to the roughly 200 people she knew there. They bought nothing. She had assumed she could tell the world what she did and people would hire her to do it. The assumption was, as she later put it, “very misguided.” Technical competence had carried her through operating work. Consulting required an entirely new front end.
She was a self-described natural introvert who suddenly needed to become a rainmaker. Around the Washington, D.C. region, she attended groups in person and online, scheduled one-to-one conversations, and learned the difference between industry networking and business-to-business networking. She also learned how difficult it was to explain strategic finance to owners who had never worked with a strategic CFO. In corporate rooms, the vocabulary had been free. Outside them, every useful sentence had to be earned.
“I was exhausted,” she recalled. The line carries no lacquer. She had become, in effect, a full-time networker who happened to own a finance firm.
The awkward months were not wasted. Lower-stakes rooms gave her somewhere to test the language. Early projects in operations and forecasting helped her understand what smaller organizations actually needed, rather than what a former corporate CFO imagined they needed. She refined the retainer offer. She noticed which businesses could use the work and which engagements merely happened to be work she could perform.
Then she treated marketing like an operating problem. In March 2024, YC Partners began working with a company on targeted outbound email. The first outbound-generated retainer started May 1. By Sithithavorn’s count, about 75 percent of the firm’s 2024 business came through outbound. Response rates later settled in the unromantic range of one to three percent positive replies. A few good clients began as people who received messages for months before agreeing to meet.
The lesson was not that outbound email is an enchanted tunnel. Sithithavorn is direct that the system is not perfectly predictable. Markets shift. Messages tire. Targets need adjustment. The deeper lesson is one an operator would appreciate: consistency matters more than a burst of enthusiasm. Switching prospecting off when delivery gets busy only schedules the next dry spell.
The solo firm that declined to stay solo
YC Partners was supposed to be simpler than all this. Sithithavorn imagined working alone with a manageable collection of clients. But the pipeline began creating a familiar capacity problem. If she served every client herself, business development would stop. When the engagements ended, she would need to restart the machine from cold. Feast, famine, networking breakfast, repeat.
So she hired before the calendar forced her hand. Someone she knew became available in the fall of 2024, and she persuaded him to join. By March 2026, the client team consisted of Sithithavorn plus four other CFOs, each carrying a different mix of industry and project experience. It was larger than she had expected before launch and smaller than she had wanted during a particularly optimistic stretch in late 2024. Her verdict was wonderfully balanced: “It is better and less good than I thought it would be at the same time.”

Her hiring criteria reveal what the firm believes a CFO is for. Candidates need technical ability, certainly, but also leadership, executive presence, confidence, and operating-company experience. A career spent only in finance firms or only in planning and analysis is not enough for her model. Nor does experience inside a giant enterprise necessarily prepare someone for smaller companies, where access to capital and management depth work differently.
The firm also refuses the temptation to become an everything shop. Sithithavorn expects YC Partners to keep adding CFO capacity, but she does not plan to bolt on bookkeeping, payroll, or tax. The boundary is strategic. Plenty of businesses sell financial chores. Her firm wants to sit closer to the moment when an owner decides whether to hire, price, expand, sell, or wait.
Read the people before prescribing the model
That work begins with discovery. The YC Partners onboarding process examines the finance team, responsibilities, internal controls, and recognition principles. It also examines the people. A fractional CFO needs to understand what the owner is trying to build, how the management team thinks, and which changes they can hear without shutting down. Asking questions is necessary. A questionnaire, Sithithavorn jokes, exists. It is not sufficient.
She borrows part of this posture from Viktor Frankl’s Man’s Search for Meaning, a book she recommended during a 2026 podcast interview. Her practical interpretation is controlled response. Pause. Avoid reacting too quickly. Give the client’s sentence enough room to become clear. It is a surprisingly human prescription from someone paid to mind the numbers, and perhaps the point of the entire practice.
“The goal isn't suspicion. It's structure.”Nicole Sithithavorn on internal controls
Her public writing repeatedly returns to structure: separating bill payment from bank reconciliation, measuring customer acquisition by segment, reducing dependence on the owner, and understanding why two companies with the same profit can carry different values. The argument is consistent. Revenue alone does not explain a business. Neither does net income. Value lives in the customer mix, the team, the controls, the ability to operate without one indispensable person, and the quality of the decisions beneath the report.
There is an echo here. Sithithavorn tells owners to build companies that do not require their hands in every decision. She also built YC Partners early enough that she would not have to remain in every client room. The operator’s advice became the founder’s constraint, and then her design brief.
The deli encounter supplied an opening. Accounting supplied a language. Ownership supplied stakes. The sale supplied perspective. YC Partners has supplied the newest education: a professional service is still a business, complete with a front end, a capacity limit, and a founder who must decide which work only she can do.
The career looks coherent now because the choices accumulated. At 21, Sithithavorn stepped through a door. Two decades of operating later, she is building doors for other owners - not exits exactly, and not guarantees, but clearer ways to see what their companies are worth, where the cash is going, and which decision deserves Monday morning.
