Langan Management Aggregator LLC has raised $5.1M over 4 rounds; too few niche peers to rank its valuation yet.

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

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

Active
  • Last raise 5 mo ago; this sector typically re-raises about every 11 months.
  • Raising on or ahead of the sector's normal rhythm.

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

Issuer-vehicle patternmedium confidence

Langan Management Aggregator 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
2.5 yr record
Peak capital year was 2025 with $2.7M across 2 filings.
Market position
ahead of 67% of Environmental Services peers
Capital scale is ahead of 67% of Environmental Services peers; modeled value is above 2% 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 2025: $2.7M across 2 filings.
  • Largest single filing was $2.5M on 2025-04-15.
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.

How it compares to the market

Benchmarked against 242 companies in Environmental Services. 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.

Raised more than 67% of sector peers (real $). Modeled value above 2% 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.
