Castle Island Brewing Company, LLC 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.

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

Fair
  • Modeled value is 0.74× the median modeled value of Pre-Seed Food & Beverage companies in 2016–2018 (72 peers) — value vs value, same stage and era.
  • Within the normal band (74% of peer median) for its niche.
Dormant
  • Last raise 9.5 yr ago; this sector typically re-raises about every 15 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

Castle Island Brewing Company, 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
11.3 yr record
Peak capital year was 2017 with $526K across 2 filings.
Market position
ahead of 57% of Food & Beverage peers
Capital scale is ahead of 57% of Food & Beverage peers; modeled value is above 58% 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
Needs review
Row-level filing totals differ from canonical totals, so amendment/superseded filtering should be checked.
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 2017: $526K across 2 filings.
  • Largest single filing was $355K on 2015-03-21.
  • Filing rows sum to $881K, while canonical raised total is $618K; likely amendments/superseded rows are mixed into the detail view.
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.
  • Canonical filtering should be tightened before using row-level totals for diligence.

How it compares to the market

Benchmarked against 567 companies in Food & Beverage. 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.

Latest round — vs other Pre-Seed rounds in sector (real $, this stage) 0.6× of median

Raised more than 57% of sector peers (real $). Modeled value above 58% of peers (estimate).

Niche peers — same stage & era

A tighter cohort than the sector chart above — only companies at the same stage (Pre-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 #46 of 72.
