B2B Marketing Efficiency Assessment Suite

What This Suite Does and Who It Is For

The B2B Marketing Efficiency Assessment Suite by The Starr Conspiracy takes your real CAC, CPL, funnel conversion rates, and pipeline ROI and returns a personalized diagnosis against segmented industry benchmarks. It is built for B2B SaaS and tech marketing leaders under budget pressure who need board-defensible performance baselines, not generic averages. Most mid-market B2B marketing teams score below the 50th percentile on at least two of four core efficiency metrics, per aggregated 2024 benchmark data from Gartner CMO Spend Survey and HubSpot State of Marketing.

Four tools, one diagnostic stack. Each one targets a distinct moment when a CMO or VP Marketing has to answer the question every board eventually asks. Are these numbers good?

How the Suite Scores Your Performance

Every tool in this suite runs on the same methodology spine. You input your actual numbers. We segment by company stage (seed through growth, growth through scale, scale through enterprise), industry vertical (B2B SaaS, HR tech, fintech, martech, broader B2B services), and ACV band (under 10k, 10k to 50k, 50k to 250k, 250k plus). Your inputs get scored against the corresponding percentile distribution.

Benchmark data is sourced from Gartner CMO Spend Survey 2024, Forrester B2B Revenue Waterfall reporting, HubSpot State of Marketing 2024, and proprietary buyer research conducted by The Starr Conspiracy across 200-plus B2B tech marketing leaders in the past 18 months. Data vintage is disclosed on every tool. Benchmark refresh runs every six months for the Benchmarking Comparator and every 12 months for the ROI Calculator.

Here is what gets exposed publicly and what gets gated. Methodology, formulas, scoring thresholds, percentile bands, and interpretation rules are all readable on this page. Your personalized output (the health score, the gap analysis, the dollar-figure ROI projection, the efficiency grade) is delivered via email after you run the tool. That is the trade. You give us a real email; we give you a board-ready diagnosis.

The Four Tools

B2B CAC Health Diagnostic

What it does. Takes your blended CAC, paid CAC, sales-assisted CAC, payback period, and LTV, then returns a CAC-to-LTV ratio health score segmented by ACV band and growth stage.

Why it matters. A 3-to-1 LTV-to-CAC ratio is the lazy benchmark everyone cites. The real picture depends on payback period and gross margin. A growth-stage B2B SaaS company with a 24-month payback and 75% gross margin needs a very different LTV-to-CAC ratio than a scale-stage company with 14-month payback. The diagnostic does that math for you.

Key input thresholds and what they mean live on the CAC benchmarks page and in our unit economics glossary entry.

Marketing Funnel Conversion Benchmarking Comparator

What it does. You input your conversion rates at each demand state (visitor to lead, lead to MQL, MQL to SQL, SQL to opportunity, opportunity to closed-won). We return percentile rankings against B2B SaaS benchmarks segmented by ACV and source mix (inbound, outbound, partner, paid).

Benchmark anchors. Median B2B SaaS visitor-to-lead conversion sits at 2.1%, MQL-to-SQL conversion at 13%, and SQL-to-opportunity at 47%, per HubSpot State of Marketing 2024 data normalized for ACV. Hitting median is not the goal. Understanding which stage is starving your pipeline is.

B2B Marketing ROI Calculator

What it does. Takes your total marketing spend (program plus headcount plus tech stack), pipeline sourced, pipeline influenced, closed-won revenue, and sales cycle length. Returns marketing-sourced ROI, marketing-influenced ROI, pipeline coverage ratio, and a 12-month projection at your current efficiency.

The formula is exposed. Marketing-sourced ROI equals (closed-won revenue attributed to marketing-sourced pipeline minus total marketing investment) divided by total marketing investment. Pipeline coverage ratio equals open pipeline divided by quarterly revenue target. Default coverage benchmark is 3x for inbound-heavy motions and 4x to 5x for outbound-heavy motions, per Forrester B2B Revenue Waterfall 2024 guidance.

Demand Generation Efficiency Scorecard

What it does. A 12-dimension scorecard across strategy, channel mix, content economics, MarTech stack ROI, attribution maturity, sales alignment, and brand-demand integration. You self-rate each dimension on a 1-to-5 scale. The scorecard returns a weighted composite grade (A through F) and identifies the two dimensions with the highest leverage for improvement.

This one is the most strategic of the four. It works best for marketing leaders building a 90-day plan or preparing a budget defense.

How to Use the Output

Run all four. Or run the one tied to the question your board is actually asking. If finance is challenging your CAC, run the CAC Health Diagnostic first. If the CEO wants to know why pipeline is light, the Funnel Comparator tells you which stage is leaking. If you are heading into budget season, the ROI Calculator and the Efficiency Scorecard together give you a defensible narrative with numbers behind it.

The output is built to be screenshotted into a board deck. That is intentional. Every chart includes data source attribution and vintage so you can defend the comparison if anyone asks.

Methodology Limitations You Should Know

Three honest caveats. First, benchmarks are directional, not prescriptive. A company outside the median is not automatically broken; a company at median is not automatically healthy. Context (stage, motion, market) matters more than the number. Second, attribution models bias every ROI calculation. Our calculator uses first-touch and multi-touch options; results vary by 15 to 40% depending on which you choose, per Ruler Analytics 2023 attribution research. Third, self-reported scorecard inputs are subject to optimism bias. Pair the scorecard with an external review when stakes are high.

Frequently Asked Questions

What is a good CAC for B2B SaaS?

A healthy CAC depends on your ACV, payback period, and gross margin, not a universal number. For B2B SaaS at growth stage with 70%-plus gross margin, an LTV-to-CAC ratio of 3:1 with under 18-month payback is the working benchmark. Scale-stage companies should target 4:1 or better. Our CAC Health Diagnostic does this math against your specific ACV band.

What is a good marketing ROI for B2B?

Marketing-sourced ROI in B2B SaaS typically lands between 5:1 and 10:1 for healthy growth-stage companies, per Gartner CMO Spend Survey 2024. Influenced ROI runs higher because more pipeline gets credit. The number that matters is your pipeline coverage ratio against quarterly target, which should sit at 3x to 5x depending on motion.

How often should I benchmark marketing performance?

Quarterly for funnel conversion and CAC. Annually for full efficiency scorecard and ROI calibration. Benchmark data itself shifts every 6 to 12 months, which is why this suite refreshes its benchmark sets on that cadence.

Are these tools free?

Yes. Methodology is fully public on this page. Personalized output is delivered via email after you run the tool. There is no payment, no sales call required, and no upsell embedded in the output.

The Bottom Line

Stop defending marketing spend with anecdotes. Run the diagnostic that maps to your board's actual question, get a segmented benchmark comparison with sourced data, and walk into the next budget conversation with numbers that hold up under scrutiny. The Starr Conspiracy built this suite because the alternative (static benchmark tables and vendor-perspective ROI narratives) is exactly why most marketing leaders lose the budget fight before it starts.
