How it compares to the market

Benchmarked against 207 companies in Climate / Cleantech. Each bar is a median (the middle company, not an average — outliers don't skew it). Two yardsticks: real money raised (reported on Form D) and modeled value (our estimate est.). These are whole-sector medians across all stages, except the per-stage row.

Total raised — vs sector median (real $, all stages) 37× above median
This company$294.4M
Sector median$8.1M
Latest round — vs other Series D+ rounds in sector (real $, this stage) 1.5× above median
This company$194.4M
Sector median$126.1M
Modeled value — vs sector median (estimate, all stages) 58× above median
This company$3.5B
Sector median$59.8M

Raised more than 91% of sector peers (real $). Modeled value above 93% of peers (estimate).

Niche peers — same stage & era

A tighter cohort than the sector chart above — only companies at the same stage (Series D+) that last raised in the same ~3-year era, ranked by modeled value est. (not money raised). This is the exact set the analyst read compares against, so a like-for-like cohort is what makes "over/under-valued" meaningful.
