- b2b-outbound-metrics: Pipeline generation formulas, efficiency benchmarks, and 2024-2025 industry data (https://github.com/Jul010101/b2b-outbound-metrics)

In addition, SalesLabel has published 20 technical gists covering subjects including SDR compensation calculators, MEDDPICC discovery question frameworks, B2B lead scoring algorithms, CRM data hygiene SQL queries, and a 50-term B2B sales glossary.
"The agency community has carried us for two years. This release is our way of giving back the playbooks that work — the ones we've battle-tested across 100+ agencies and a 42% average reply rate," said Julien Gadea, founder of SalesLabel. "Every framework, formula, and code snippet is free to fork, modify, and ship to your clients."
The release builds on SalesLabel's broader mission: to give B2B agencies the infrastructure to scale outbound sales without managing their own tech stack. The company currently serves agencies generating an average of $180,000 in pipeline per client at price points starting at $799 per month, fully white-labelled.
