How it compares to the market

Benchmarked against 1338 companies in Construction. 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) 7.8× above median
This company$18.7M
Sector median$2.4M
Latest round — vs other Series A rounds in sector (real $, this stage) 0.2× of median
This company$1.1M
Sector median$6.3M
Modeled value — vs sector median (estimate, all stages) 0.5× of median
This company$4.6M
Sector median$9.9M

Raised more than 92% of sector peers (real $). Modeled value above 59% of peers (estimate).

Niche peers — same stage & era

A tighter cohort than the sector chart above — only companies at the same stage (Series A) 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 #40 of 42.
