The State of Commercial Open Source 2025 report finds that venture-backed commercial open source software (COSS) startups had higher average exit valuations than closed-source peers: 7x at IPO and 14x at mergers and acquisitions (M&A), according to the Linux Foundation’s release. Those are report-level averages, not a promise that an open-source business will outperform any particular competitor.
Produced by Linux Foundation Research, the Commercial Open Source Startup Alliance (COSSA), and Serena, the report examines venture funding and exits alongside company-managed GitHub community indicators. Its figures offer a lens on startup finance—not a guarantee of returns for founders or investors.
What is the 2025 State of Commercial Open Source?
It is a research report about the financial outcomes of commercial open source companies and the relationship between community health and commercial performance. The report was produced collaboratively by Linux Foundation Research, COSSA, and Serena. Its named authors are Sam Boysel of The Linux Foundation, Matthieu Lavergne of Serena, and Matt Trifiro of COSSA.
The Linux Foundation’s public release, dated August 25, 2025, says the study focuses on venture-backed startups, with especially pronounced results in infrastructure software. A Japanese-language regional announcement followed on September 18, 2025.

What data does the report cover?
The report brings together two datasets with different time spans and purposes:
| Dataset | Coverage | What it measures |
|---|---|---|
| Financial | More than 800 VC-backed COSS companies globally, 2000–2024 | Funding and company outcomes over 25 years |
| Community | Public GitHub repositories managed by companies in the sample, June 2022–May 2025 | Community indicators assessed using OpenSSF’s Criticality Score |
The community observation period covers nearly three years, not the full 25-year financial history. The two datasets therefore should not be treated as if they measured the same companies’ financial and community outcomes continuously across the same period.
What are the report’s headline financial findings?
Funding
The Linux Foundation’s 2025 release reports $26.4 billion in aggregate funding for COSS startups in 2024. This is a total across the category, not a typical funding amount for an individual company.
IPO and M&A valuations
The release reports that average valuations for COSS startups were 7x greater at IPO and 14x greater at M&A than for closed-source peers. These comparisons describe the averages reported for the study’s groups; they do not establish that every COSS company receives a higher valuation than every proprietary-software company.

Other outcomes
The official summary also describes differences in funding speed and liquidity outcomes, and says the findings are especially pronounced in infrastructure software. The public source material does not provide detailed subgroup estimates for these comparisons, so it is not possible to quantify how large those differences were across particular software areas or company types.
Does commercial open source outperform closed-source companies?
The report’s reported averages favor COSS startups on the highlighted IPO and M&A valuation measures. That is evidence of a difference in the groups studied, not proof of universal outperformance or a prediction for a new company. The report’s comparison is with closed-source peers, but the public release does not explain enough about peer matching, valuation normalization, or the composition of each subgroup to evaluate how those choices affect the results.
For a founder or investor, the practical takeaway is to treat the findings as context for evaluating a business model, not as a substitute for company-specific analysis. The headline averages alone do not establish likely funding, exit timing, valuation, or liquidity for a particular startup.
What does the report say about community health?
The report summary says “strong community health is closely linked to higher company valuations.” Community indicators were assessed with OpenSSF’s Criticality Score using public GitHub repositories managed by companies in the sample during June 2022–May 2025.

“Linked” is important: the reported relationship is an association, not evidence that improving a repository’s score causes a company’s valuation to rise. The available summary does not establish the direction of influence or rule out other factors that could be related to both community activity and company value.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How should readers interpret the results?
- Keep the comparison in view: the valuation multiples compare average COSS outcomes with closed-source peers, not with every software company or investment.
- Separate the time windows: financial coverage runs from 2000 through 2024; GitHub indicators run from June 2022 through May 2025.
- Do not generalize from the infrastructure finding: the public summary says results are especially pronounced in infrastructure software, but does not provide detailed subgroup numbers.
- Distinguish association from cause: the community finding does not show that community health alone produces a higher valuation.
- Recognize what the public release leaves unspecified: it does not surface matching rules, confidence intervals, valuation-normalization details, or enough methodology to assess statistical uncertainty.
