How it compares to the market

Benchmarked against 2067 companies in AI / ML. 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) 31× above median
This company$148.5M
Sector median$4.7M
Latest round — vs other Series C rounds in sector (real $, this stage) 1.3× above median
This company$73.0M
Sector median$55.3M
Modeled value — vs sector median (estimate, all stages) 20× above median
This company$554.6M
Sector median$27.9M

Raised more than 98% of sector peers (real $). Modeled value above 96% 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 #5 of 16.
