As batteries become the marginal grid asset, the software that decides when to charge, discharge, and which market to bid into is becoming a distinct, asset-light business from the battery hardware itself -- real, but still small and financially fragile at its one public pure-play.

| Indicator | Score | Reading |
|---|---|---|
| Maturity higher is better · high confidence | 47/100 | Software-driven dispatch is live and revenue-generating at real scale, but the standalone business model is unproven -- Stem's distress is the cautionary data point. |
| Evidence Strength higher is better · high confidence | 69/100 | SEC filings and a CAISO regulator report anchor the evidence, but most vendor performance claims remain self-reported or only trade-press corroborated. |
| Commercial Proximity higher is better · high confidence | 62/100 | Real contracted revenue exists today at several private platforms and the near-term wedge (grid-services revenue capture) is proven, but the one public-market vehicle (Stem) is financially fragile. |
| Capital & Policy Support higher is better · medium confidence | 33/100 | Market-design changes (ERCOT RTC+B, CAISO ancillary-services evolution) are a real structural tailwind, but there is no dedicated public funding programme for optimization software itself. |
| Crowding Risk lower is better · high confidence | 22/100 | The theme is under-owned and thinly covered; Stem's distress and the mostly-private cohort keep positioning and valuation low, not crowded. |
| Reflexivity Risk lower is better · high confidence | 68/100 | The one listed pure-play (Stem) is acutely capital-markets dependent; private platforms depend on VC funding rounds rather than public-market sentiment. |
