Engineering acceleration
The deterministic exclusion rule that removes commits authored by automated accounts (Dependabot, Renovate, GitHub Actions, and any account name matching the substring 'bot') before any aggregation runs. Bot filtering is applied at the commit level, not the repository level, so a human-authored commit in a repo that also receives bot traffic is still counted. Without this filter the framework-migration signal type would be inflated by lockfile churn and the resulting ranking would be noise.
Metrics, signal types, and decision rules from the methodology.
The named mechanism behind VC Deal Flow Signal.
The total number of commits to a startup's most active public GitHub repository over a rolling 14-day window.

Any data-driven indicator that helps an investor identify a promising startup before traditional deal sourcing channels surface it.
The change in the number of unique contributors to a startup's GitHub repository over time.
A signal type indicating that a startup's contributor growth rate exceeds 50% in a short window.
