Rapamycin Holdings, Inc. looks fair 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 pharma sector profile.

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

Fair
  • Modeled value is 1.42× the median modeled value of Series A Pharmaceuticals companies in 2019–2021 (76 peers) — value vs value, same stage and era.
  • Within the normal band (142% of peer median) for its niche.
Dormant
  • Last raise 7.0 yr ago; this sector typically re-raises about every 13 months.
  • Silent for over 3× the sector's normal cadence.

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

Issuer-vehicle patternmedium confidence

Rapamycin Holdings, Inc. 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
13.0 yr record
Peak capital year was 2019 with $7.0M across 1 filings.
Market position
ahead of 64% of Pharmaceuticals peers
Capital scale is ahead of 64% of Pharmaceuticals peers; modeled value is above 69% 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 2019: $7.0M across 1 filings.
  • Largest single filing was $7.0M on 2019-07-01.
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 1613 companies in Pharmaceuticals. 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) 2.2× above median
This company$17.9M
Sector median$8.1M
Latest round — vs other Series A rounds in sector (real $, this stage) 1.3× above median
This company$7.0M
Sector median$5.2M
Modeled value — vs sector median (estimate, all stages) 2.8× above median
This company$216.8M
Sector median$76.1M

Raised more than 64% of sector peers (real $). Modeled value above 69% 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 #20 of 76.
