Incubator by the Numbers (2015–2025) - A concise, data-driven view of how incubation has shifted over a decade
This brief summarises ten years of Incubator data (2015–2025) covering podling lifecycles, releases, community growth, governance activity, and system behaviour. The aim is to highlight observable trends using consistent, decade-long signals. This is a summary of 10 years of the Incubator.
Intake has declined, and long-running stalled podlings from the mid-2010s have largely been resolved. A smaller Incubator naturally produces fewer graduations, fewer release votes, fewer governance threads, and fewer problem cases.
Graduation timing tracks podling population:
Modern podlings progress through early milestones sooner, due to both:
Fully matured cohorts (2015–2020) show stable outcomes:
Retirement typically occurs 40–60 months after entry. Cohorts entering after 2019 have not yet reached this window, so apparent declines in retirements are age-based, not behavioural.
Release attempts now occur earlier and more consistently.
Normalised release votes:
Technical issues (LICENSE/NOTICE/DISCLAIMER, naming, packaging) are significantly less common than in the mid-2010s. Most modern release issues are behavioural rather than technical.
Across all cohorts, the timing of the first release is the strongest early indicator of long-term trajectory.
Podlings that release sooner tend to:
Podlings that substantially delay their first release show the same early-stall patterns seen in most historical retirees.
Graduating podlings consistently reach key milestones earlier:
Retiring podlings show opposite patterns: late or absent releases, no governance additions, long quiet periods, and work concentrated in 1–2 individuals.
Using the earliest of the first committer or first PPMC addition (excluding bootstrap), modern podlings add their first new governance participant significantly sooner than mid-2010s cohorts.
Across the decade, first governance additions occur earlier, with less variance and far fewer long delays. This aligns with earlier releases, more consistent progression, and fewer stalled podlings.
Successful podlings show regular dev@ governance activity and fewer extended quiet phases than in the mid-2010s. Normalised dev@ governance load remains stable across the decade and aligns with expectations for project-level decision-making.
Vote threads form a slightly larger share of general@ activity in recent years. Non-vote governance threads per podling are slightly lower in later years, while vote-related threads have increased. Oversight per podling remains stable once podling count is normalised.
Show full life cycles: early graduates and late retirees.
Show early graduates, but few/no retirements due solely to cohort age. Only time-to-graduation has changed significantly; historically, retirement patterns remain consistent.
Taken together, the data shows a program that is smaller, more consistent, and more predictable than a decade ago, operating with stable oversight in a context of clearer expectations and earlier podling progress.
