If you’re a Series A founder reading job descriptions for finance leaders and finding that “controller,” “VP Finance,” and “CFO” all sound like roughly the same job, you’re not wrong to be confused. The titles are used loosely across startups. But they describe genuinely different jobs at genuinely different stages — and hiring the wrong one first is one of the most common, expensive mistakes Series A companies make.
The short version: most Series A startups need a controller plus a fractional CFO, not a full-time VP Finance or CFO. The rest of this post explains why, and how to know when each role becomes the right next hire.
Three roles, three jobs
Controller. A controller closes the books. They own accounting accuracy: making sure transactions are recorded correctly, accruals are right, the trial balance ties, the monthly financial package is produced on schedule, and audit support is in place. They live in the accounting platform (QuickBooks, NetSuite) every day. They manage AP, AR, payroll integration, and the bookkeeper if there is one. They are not strategists — their job is to produce reliable financial truth. A Series A controller in the US in 2026 costs $120,000–$180,000 in base salary, plus equity. A senior controller at a Series B or C company can run $180,000–$250,000.
VP Finance. A VP Finance builds the finance team and runs FP&A. They sit on top of the controller and own forward-looking finance: planning, forecasting, budgeting, scenario analysis, and increasingly, board-level reporting. They typically manage the controller and FP&A analysts. They have an opinion on systems, financial policy, and team design. A Series B VP Finance costs $200,000–$280,000 in base salary, plus equity, and they generally come from a finance org background (Big Four → senior finance role at a Series C company, or similar). VP Finance is not a substitute for a controller — they need a controller working underneath them to be effective.
CFO. A CFO owns the entire finance function: strategy, board, investor relationships, fundraise execution, capital allocation, and increasingly, M&A and corporate development. They speak for the company financially. A full-time CFO at a Series B or C startup costs $300,000–$450,000 in base salary, plus typically 0.5–1.5% in equity. Below Series B, a true CFO is usually overkill — you’re paying for capacity you can’t use, and the right person won’t take the job.
Fractional CFO. A fractional CFO does the strategic part of the CFO job — board reporting, investor relations, fundraise prep, scenario planning, and high-level strategic input — without the full-time cost or commitment. They are not a controller, and they do not close your books. They cost $5,000–$20,000 per month depending on intensity. They are how most Series A and B startups get CFO-level strategic input before they’re ready to hire a full-time CFO.
Who do I hire first?
The answer depends on what’s broken right now. Here’s the decision tree we use with Series A founders.
If your books are unreliable or close late, hire a controller first. This is the single most common situation. The bookkeeper is fine at AP/AR but the close takes 30+ days, the trial balance has unexplained variances, and you don’t trust the numbers in your dashboards. A controller will fix this. A fractional CFO will not — they can identify the problem but they will not close your books for you.
If your books are clean but your board doesn’t have visibility, hire a fractional CFO. This is the second-most-common situation, often emerging right after a Series A close. The bookkeeper or controller produces accurate financials, but nobody is building the narrative: KPI dashboards, variance analysis, runway scenarios, board memos. A fractional CFO owns this. A controller will not — it’s outside their lane.
If both are broken, hire the controller first, then add a fractional CFO three to six months later. Trying to do both at once usually means neither gets done well. A controller stabilizes the data; once the data is reliable, a CFO can build a useful narrative on top of it.
You almost certainly do not need a full-time VP Finance yet. A VP Finance is the right hire when (a) you have a controller already, (b) you’re heading into a Series B or C, and (c) the FP&A workload exceeds what a fractional CFO can absorb. For most Series A companies, a controller plus a fractional CFO is structurally what a VP Finance would do anyway, at a fraction of the cost.
You almost certainly do not need a full-time CFO yet. A full-time CFO becomes worth it when you have full-time finance team to lead (a VP Finance, a controller, FP&A analysts), when board and investor activity is too constant for a fractional engagement to handle, and when you have the capital allocation problems that justify CFO-level decision-making. That’s usually Series C+ — and we’d argue most companies should wait even longer than they think.
The most common mistakes
Three patterns we see repeatedly:
-
Hiring a “CFO” who is actually a controller. A Series A founder posts a CFO job description, gets candidates with controller backgrounds, hires one, and is surprised six months later that they don’t have an investor narrative or a Series B model. The candidate did exactly what their experience prepared them to do — close books accurately. The founder needed strategy. The title was wrong.
-
Expecting a controller to do strategy. A Series A controller who’s good at their job is producing reliable financials by business day 10 every month and managing the auditor relationship. Asking them to also build a Series B model and present at board meetings is asking for two jobs. Either you’ll get a mediocre version of both, or the controller will leave for a role that matches their actual skillset.
-
Expecting a fractional CFO to fix bad books. A fractional CFO at $7,500/month is a CFO with maybe four days of bandwidth per month. They will not spend those four days cleaning up your QuickBooks file. If the underlying accounting is broken, the strategic work on top of it will be wrong. Fix the data first, then layer strategy on top.
What Pegacorn does and doesn’t
Pegacorn provides fractional CFO services for Series A and B startups. We also provide accounting and bookkeeping when companies need it — including the controller-level work of monthly close, GAAP compliance, and audit prep. For full-time hires (controller, VP Finance, CFO), we don’t recruit, but we can help you scope the role properly, write a defensible job description, and review candidates’ finalists if you’d like a second opinion on whether their skills match what you actually need.
If you’re not sure which role you need first, tell us what’s broken and we’ll tell you honestly whether we’re the right fit — or which kind of hire you should be making instead.
