Methodology

This hub aggregates 18 quantitative benchmarks published between 2022 and 2024. Primary sources include published analyst research, industry state-of-marketing and state-of-sales reports, and recognized B2B demand generation benchmark studies. Each stat includes the number, source category, and date.

The Starr Conspiracy proprietary benchmarks (MQL Cost to Pipeline Dollar Conversion and Nurture Track Completion Rate) are drawn from anonymized client data across 42 B2B technology companies between Q1 2023 and Q4 2023, with company revenue ranging from $10M to $500M ARR. Values are reported as medians. Limitations: proprietary benchmarks are directional and vary by industry mix, geography, and marketing automation tooling. Geographic scope is primarily North America. Sample is weighted toward enterprise software and HR technology.

Where multiple credible sources publish conflicting values, we report the most recent primary source figure. Values are replaced when the source publisher releases updated research; the URL remains stable across refreshes.

Frequently Asked Questions

What is a good MQL-to-SQL conversion rate for B2B SaaS?

Published industry research puts the average at 25.9%, with best-in-class teams reaching 35%. In our client data, mid-market SaaS typically runs 2 to 4 points below enterprise averages due to thinner behavioral signal density. For threshold tuning, see our lead scoring calibration guide.

How often should B2B lead scoring models be refreshed?

Published analyst research recommends a 90-day refresh cadence at minimum. Models older than 6 months drift toward prior-quarter buying patterns and miss shifts in intent signal weight. In high-velocity SaaS with weekly campaign changes, monthly recalibration of behavioral weights pays off.

What is the benchmark for B2B lead response time?

Best-in-class response time for inbound MQLs is under 5 minutes per published lead response research. The actual median across B2B is 42 hours per the 2023 industry lead response report, a gap of more than 500x.

How do MQL, SQL, and SAL definitions vary across studies?

Definitions differ by publisher. Industry research typically defines SAL as a marketing-passed lead formally accepted by sales within an agreed SLA, with 56% as the cross-industry average. Automation-system stage transitions tend to inflate MQL-to-SQL conversion versus CRM-based measurement by roughly 3 to 5 points. Review our demand generation strategy framework for definition reconciliation.

How were these benchmarks sourced and verified?

Each of the 18 benchmarks names a specific source category and publication date. Primary sources were preferred; secondary citations were included only when they explicitly named the original research. Two benchmarks are proprietary to The Starr Conspiracy and reflect anonymized data from 42 B2B technology clients between Q1 and Q4 2023.
