Go-To-Market Index

The Go-to-Market Index (GTM Index) is our commercial readiness score for an open source project. We measure how suitable the project is for use in production products or services

Evaluation Criteria

License & IP Clarity (20%)

  • Are patents or trademarks clearly addressed?
    • Is it OSHW-certified or under a permissive license?

      Design Documentation Quality (20%)

      • Are full schematics, PCB layouts, BOMs, and mechanical drawings available?
        • Are files in open formats (KiCad, STEP, Gerber) rather than proprietary only?

          Manufacturability (20%)

          • Are parts available from multiple suppliers?
            • Is there a tested reference design or build guide?
              • Are there known manufacturing partners or open tooling?

                Technical Maturity (15%)

                • Is the design tested and validated?
                  • Are there reference builds in the wild?
                    • Does it have stable revisions or frequent breaking changes?

                      Community & Ecosystem (15%)

                      • Are there contributors or companies already building with it?
                        • Are there forks, derivative products, or adoption by real users?

                          Support & Longevity (10%)

                          • Are maintainers active and responsive?
                            • Are there commercial support or consulting options available?

                              Scoring System

                              1 = risky / experimental (concept only, no builds yet)

                              3 = usable but needs work (prototype exists, limited docs)

                              5 = production-grade (validated design, manufacturing data ready, active community)

                              Weight each category as shown above → calculate a 0–100 readiness score.

                              Calculate the Overall Score

                              Add up weighted scores → final score out of 100. Convert into a readiness band:

                              0–40: Experimental

                              41–70: Commercially usable with caution

                              71–100: Production-ready / enterprise grade
