Tendril Holdings, LLC looks under-valued against its niche peers and is quiet on financing cadence.

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

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

Under-valued
  • Modeled value is 0.40× the median modeled value of Series D+ Other Energy companies in 2025–2027 (7 peers) — value vs value, same stage and era.
Quiet
  • Last raise 16 mo ago; this sector typically re-raises about every 12 months.
  • Slightly overdue versus sector 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

Tendril Holdings, 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
4.7 yr record
Peak capital year was 2025 with $190.0M across 5 filings.
Market position
ahead of 98% of Other Energy peers
Capital scale is ahead of 98% of Other Energy peers; modeled value is above 95% 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Row-level filing totals differ from canonical totals, so amendment/superseded filtering should be checked.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 2025: $190.0M across 5 filings.
  • Largest single filing was $101.9M on 2021-12-13.
  • Filing rows sum to $378.3M, while canonical raised total is $246.3M; likely amendments/superseded rows are mixed into the detail view.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.
  • Canonical filtering should be tightened before using row-level totals for diligence.

How it compares to the market

Benchmarked against 2049 companies in Other Energy. 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) 72× above median
This company$246.3M
Sector median$3.4M
Latest round — vs other Series D+ rounds in sector (real $, this stage) 0.5× of median
This company$48.0M
Sector median$105.3M
Modeled value — vs sector median (estimate, all stages) 26× above median
This company$443.0M
Sector median$17.0M

Raised more than 98% of sector peers (real $). Modeled value above 95% of peers (estimate).

Niche peers — same stage & era

A tighter cohort than the sector chart above — only companies at the same stage (Series D+) 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 #7 of 7.
