How it compares to the market

Benchmarked against 701 companies in Mining & Resources. 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) 1.9× above median
This company$4.3M
Sector median$2.3M
Latest round — vs other Seed rounds in sector (real $, this stage) 0.2× of median
This company$220K
Sector median$1.1M
Modeled value — vs sector median (estimate, all stages) 0.3× of median
This company$648K
Sector median$2.5M

Raised more than 66% of sector peers (real $). Modeled value above 21% of peers (estimate).

Niche peers — same stage & era

A tighter cohort than the sector chart above — only companies at the same stage (Seed) 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. This company ranks #54 of 63.
