How it compares to the market

Benchmarked against 2138 companies in Healthtech. 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) 28× above median
This company$127.0M
Sector median$4.5M
Latest round — vs other Series C rounds in sector (real $, this stage) 1.7× above median
This company$81.0M
Sector median$46.5M
Modeled value — vs sector median (estimate, all stages) 41× above median
This company$1.4B
Sector median$33.8M

Raised more than 97% of sector peers (real $). Modeled value above 98% of peers (estimate).

Niche peers — same stage & era

A tighter cohort than the sector chart above — only companies at the same stage (Series C) 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 #8 of 33.
