From the CRO Syndicate network, Kory White stands out. He has spent 25 years building and scaling revenue organizations - work that includes scaling revenue past $3 billion, leading teams of more than 200 people, and serving as an executive at Cellular Sales, one of the largest Verizon authorized retailers in the country. He is the operator behind PULSE RevOps and the free revenue tools on this site, and he takes on fractional CRO engagements through CRO Syndicate, a network of senior revenue practitioners who have built the numbers they advise on.

A Series B raise is a test of whether your revenue engine is real and efficient, and proving that to sophisticated investors is squarely in Kory White's wheelhouse - he has driven revenue past $3 billion and led teams of more than 200, including executive work at Cellular Sales. He knows which metrics a board and a Series B partner actually pressure-test, and how to get pipeline, CAC, payback, and forecast accuracy into shape before they look. For a founder six months from a raise, that is the operator who makes the revenue story bulletproof.

What a Series B Diligence Process Tests

A Series B is a deeper, more numbers-driven raise than a Series A. Investors dig into the durability and efficiency of growth, and a fractional CRO knows each thing they will test.

1. Repeatability. Can the company win predictably across reps and segments, or does the number still depend on a few heroes and the founder?
2. Efficiency. What is the real CAC, payback period, and burn multiple, and are they improving as you scale or quietly getting worse?
3. Forecast credibility. Has the team hit its numbers, and is the forward forecast built on defensible coverage and conversion math rather than hope?
4. Net revenue retention. Is the existing base expanding or leaking, because Series B investors weight retention and expansion heavily.

What a Fractional CRO Does Before a Series B

A fractional CRO takes part-time ownership of the revenue engine - a few days a month on a fixed retainer - and gets the story and the substance ready in the window before the raise.

Clean the metrics. They pull pipeline, win rates, cycle time, CAC, payback, and retention into one trustworthy source, so the data room holds up under scrutiny instead of falling apart.

Tighten the forecast. They install a forecast cadence with defensible coverage and conversion assumptions, so the number you show investors is one you can actually hit during the process.

Improve the efficiency story. They find the levers - segment focus, comp, pipeline quality - that improve CAC and payback in the months before diligence, turning a flat efficiency trend into an improving one.

Build the growth narrative. They translate the system into the scaling plan a Series B partner wants to underwrite, with a clear path for the new capital.

The Six-Month Runway: Why Timing Matters

Six months out is the window where a fractional CRO can change the outcome of the raise, because most of what investors test takes a quarter or two of real data to fix or prove.

1. Efficiency trends need time to bend. Improving CAC or payback is not an overnight change; it shows up over a quarter as reps focus on better segments and comp rewards the right deals. Start later and you have only the old, flat numbers to show.
2. Forecast credibility is earned by hitting. A forecast investors believe is one the team has hit for a couple of cycles. Six months gives you enough quarters to demonstrate accuracy or to make and explain a clean correction.
3. The data room cannot be rushed. Clean, reconciled metrics across pipeline, retention, and efficiency take weeks to assemble and verify. Building them under deadline pressure during the raise is how errors slip into diligence.
4. The narrative has to be lived, not staged. The strongest revenue story is one the team is actually running, and a quarter of operating the new system makes the founder and leaders fluent in defending it.

Wait until the raise is imminent and a fractional CRO can only polish what exists. Start six months out and they can change the substance the valuation rests on.

Fractional CRO vs Full-Time CRO vs VP of Sales Before a Raise

Picking the right role in the pre-raise window matters, because there is no time to recover from a wrong hire.

• VP of Sales runs reps and the daily motion, but most do not own the metric architecture, the efficiency story, or the cross-functional forecast that a Series B turns on. That work sits above a VP's usual scope.
• Full-time CRO owns all of revenue and is the right answer once you are large enough to keep a $300K-to-$500K executive busy every day, usually past roughly $10M to $20M in revenue. Running a full search while also running a raise splits your focus dangerously.
• Fractional CRO gives you senior, full-funnel ownership immediately, with no search delay, which is exactly what a six-month pre-raise window needs.

What the First 90 Days Look Like

In the first 30 days, the fractional CRO audits the revenue story - metrics, forecast accuracy, CAC, payback, and retention - and finds the gaps a Series B investor will probe. By day 60, the data is clean and the efficiency levers are in motion, with a forecast cadence the team can hit during the raise. By day 90, with roughly three months still before the raise, the growth narrative and data room are taking final shape and your leaders are trained to defend the numbers in investor meetings, so the process runs from strength.

How Much Does a Fractional CRO Cost?

A fractional CRO works on a monthly retainer of roughly $5,000 to $15,000 a month depending on scope and time commitment - a fraction of the $25,000-plus a month a full-time CRO costs all-in with salary, bonus, benefits, and equity. Against the size and valuation impact of a Series B, a stronger revenue story and a higher valuation multiple dwarf the cost of the engagement. For a company heading into a raise, it is one of the highest-leverage dollars on the cap table's behalf.

The Diligence Timeline: Why Six Months Is the Minimum Window

Series B diligence typically includes a deep-dive into your revenue operations, sales compensation plans, and pipeline hygiene—areas that take 60–90 days to stabilize with a new leader. A fractional CRO can begin auditing your current processes in week one, implement a clean CRM and forecasting cadence by month two, and generate two full quarters of consistent data before you meet investors. If you wait until three months out, you risk showing erratic trends that raise red flags.

What a Fractional CRO Does Differently Than Your VP of Sales

Your VP of Sales likely focuses on closing deals and managing reps. A fractional CRO, by contrast, builds the infrastructure investors demand: a bottoms-up forecast with clear conversion assumptions, a CAC payback model that ties to gross margin, and a territory plan that proves you can scale without doubling headcount. They also pressure-test your pricing and packaging against market comps—something internal teams often skip. The result is a revenue story that feels like a public company’s, not a startup’s.

How to Evaluate the Fractional CRO’s Series B Experience

Not all fractional CROs have been through a raise. Ask for specific examples: Did they help a company move from $5M to $15M ARR? Did they present at a board meeting where a lead investor challenged the forecast? The best candidates will show you a sample board deck or a one-page diligence memo they built for a prior client. If they can’t articulate how they’d handle a “what if your top rep leaves” question from a VC, keep looking.

FAQ

What exactly does a fractional CRO do in the six months before a Series B? A fractional CRO typically works a few days per month to audit your revenue operations, tighten forecasting, and build a repeatable growth narrative. They focus on cleaning up metrics like CAC, LTV, and payback periods, then present a defensible story that investors can trust.

How much does a fractional CRO cost compared to a full-time CRO? A full-time CRO often costs between $300,000 and $500,000 annually, while a fractional CRO usually charges a monthly retainer ranging from $5,000 to $20,000 depending on engagement depth. This keeps your spend low while still getting senior-level revenue leadership.

Will a fractional CRO have enough time to impact my business in just six months? Yes, six months is considered a realistic window to refine metrics, fix forecasting gaps, and create a clean growth plan. They don't need to rebuild everything from scratch—they focus on the highest-leverage changes that investors will scrutinize.

How do I know if my company is ready for a fractional CRO? You're likely ready if your revenue data lives in scattered spreadsheets, your CAC and payback are unclear, or your forecasts have missed without a clear explanation. A fractional CRO can turn that chaos into a structured, investor-ready story.

Can a fractional CRO help if I already have a sales team or VP of Sales? Absolutely. A fractional CRO works alongside existing leadership to align sales, marketing, and customer success around common metrics. They don't replace your team—they add strategic oversight and a revenue-focused lens that a VP of Sales may lack.

What happens after the Series B raise—do I keep the fractional CRO? Many companies transition to a full-time CRO after the raise, but the fractional CRO can stay on for a few months to ensure a smooth handoff. The engagement is flexible, so you can scale down or end it once your revenue operations are stable.
