California Proton Treatment Center, LLC looks over-valued against its niche peers and is dormant on financing cadence.

Synthesized from the figures below est. — every claim rests on a number shown on this page. Valuation uses the health services sector profile.

Analyst read est. — computed against this company's niche peers in the same era. Inputs shown; not a quoted figure.

Over-valued
  • Modeled value is 1.99× the median modeled value of Seed Hospitals and Physicians companies in 2007–2009 (22 peers) — value vs value, same stage and era.
Dormant
  • Last raise 16.7 yr ago; this sector typically re-raises about every 12 months.
  • Only one round on record and long silent — often defunct, acquired, or gone quiet.

Procedural diagnosis est. — rule-based common-sense checks over the filing pattern, issuer name, activity cadence, and surfaced operating evidence.

Issuer-vehicle patternmedium confidence

California Proton Treatment Center, LLC behaves more like a recurring private-offering issuer than a conventional venture-backed operating company.

Issuer structure
Company-like
No recurring-offering pattern strong enough to override normal financing interpretation.
Lifecycle
16.8 yr record
Peak capital year was 2009 with $3.2M across 1 filings.
Market position
ahead of 63% of Hospitals and Physicians peers
Capital scale is ahead of 63% of Hospitals and Physicians peers; modeled value is above 79% of peers by modeled value. Large capital with mid-pack modeled value can signal an issuer/program profile rather than operating-company growth.
Valuation reliability
Normal applicability
Stage/dilution valuation models are weakest when the issuer is broad-sector, recurring, or vehicle-like.
Operating evidence
Sparse
No clear CEO/founder/principal role is surfaced, so operating-company confidence is lower.
Data quality
Consistent
Canonical totals and visible filing detail are broadly aligned.
What triggered this
  • Legal name looks like an issuer vehicle rather than a product company.
  • No clearly named CEO/founder/principal role in the public records surfaced here.
  • No verified homepage on the profile yet.
  • Capital program peaked in 2009: $3.2M across 1 filings.
  • Largest single filing was $3.2M on 2009-10-01.
How to read the page
  • Read this less like a startup funding journey and more like a capital-raising program.
  • Stage-based valuation and peer labels have lower applicability for this pattern.
  • The more important signal is lifecycle: repeated filings ended years ago, so current activity needs outside confirmation.

How it compares to the market

Benchmarked against 599 companies in Hospitals and Physicians. 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) 1.8× above median
This company$3.2M
Sector median$1.8M
Latest round — vs other Seed rounds in sector (real $, this stage) 1.9× above median
This company$3.2M
Sector median$1.6M
Modeled value — vs sector median (estimate, all stages) 3.2× above median
This company$73.8M
Sector median$22.9M

Raised more than 63% of sector peers (real $). Modeled value above 79% 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 #4 of 22.
