B2B Inbound Demand Engine Assessment Suite

The B2B Inbound Demand Engine Assessment Suite by The Starr Conspiracy scores your readiness across five inbound channels (content, email, SEO, social, syndication), calculates pipeline ROI, and benchmarks your performance against named B2B datasets. It is built for marketing leaders under board-level ROI pressure. Roughly 68% of B2B teams that complete the suite score under 60 out of 100 on integrated channel maturity, per our 2024 sample of 312 mid-market assessments.

How the Suite Scores Your Engine

Four tools. One methodology. You can run them in any order, but the sequence below matches how most marketing leaders rebuild under pressure.

1. Inbound Demand Engine Readiness Assessment. Scores nine maturity dimensions across Strategy and Vision, Data and Infrastructure, and Talent and Organization on a 0-100 scale.
2. B2B Pipeline ROI Calculator. Translates traffic, conversion rate, MQL-to-SQL ratio, average deal size, and sales cycle length into projected pipeline and payback period.
3. Inbound Channel Mix Benchmarking Comparator. Compares your channel-level cost-per-qualified-lead and win rate against segmented benchmarks from HubSpot's 2024 State of Marketing, Salesforce's State of Marketing 7th Edition, Parse.ly's content benchmark data, and Mailchimp's B2B email benchmark report.
4. Demand Engine Archetype Diagnostic Quiz. Routes you to one of four rebuild archetypes (Foundation, Optimization, Acceleration, Transformation) based on weighted scoring of your gaps.

Every formula, rubric, and benchmark range is published on the tool's companion page. No hidden math. No platform-lock bias. If you can read the page, you can defend the score to your board.

What Each Tool Actually Produces

The Readiness Assessment produces a 0-100 maturity score plus dimension-level subscores. The ROI Calculator produces a 12-month pipeline projection with sensitivity ranges at plus or minus 20%. The Benchmarking Comparator produces a side-by-side table of your metrics against industry medians by company size and ICP segment. The Diagnostic Quiz produces an archetype assignment and a prioritized rebuild sequence.

Gated outputs are personalized only. The methodology stays public.

Methodology Sources and Transparency

Benchmark inputs are drawn from publicly cited B2B datasets, including HubSpot's annual marketing benchmark (2024), Salesforce's State of Marketing report, Parse.ly's content engagement dataset, and Mailchimp's B2B email performance benchmarks. Static checklist methodologies referenced from agency audit frameworks at 42dm.net and aira.net informed our gap analysis criteria but were rebuilt with weighted scoring rather than yes/no checklists. Sample size for our internal calibration dataset is 312 mid-market B2B technology companies assessed between January 2023 and October 2024. Limitations: the suite assumes a defined ICP and an active CRM. Companies with neither should run the Readiness Assessment first and skip the ROI Calculator until ICP and attribution are stable.

How to Interpret Your Score

A Readiness score of 0-39 means your inbound engine is unstructured and channel-fragmented. A score of 40-69 means you have functional channels but no integrated measurement. A score of 70-89 means you have integrated measurement but unrealized scale. A score of 90-100 means you are operating at a level that justifies aggressive AI-native expansion. The Diagnostic Quiz maps these ranges to the four archetypes so you do not have to guess what to do next.

Who Should Run the Suite

VP and CMO-level marketing leaders at B2B technology companies between $10M and $500M in revenue who are accountable for pipeline contribution and who are being asked to defend marketing spend with attribution math their CFO will accept. If you are running fewer than three inbound channels or your team is under five marketers, start with the Readiness Assessment alone.

The Bottom Line

Your board does not want a marketing maturity slide. It wants a number, a benchmark, and a rebuild plan. Run the suite, expose the methodology, and walk into the next QBR with a defensible diagnosis instead of a defensive narrative. Start with the Readiness Assessment, then layer in the ROI Calculator once you know where the gaps are.
