What companies are currently in Black Diamond Capital Management’s active portfolio and who sits on their boards?

1. What Black Diamond publishes: named portfolio companies and claimed board links

Black Diamond’s corporate site lists a set of portfolio companies by example, naming Consumer Portfolio Services, ION Media, Werner Ladder, White Birch, Bayou Steel, SmarteCarte, Sun World and PTC Alliance as companies on which founder Stephen Deckoff "has held or currently holds board seats" ^[1]. That same firm biography also states that other senior principals carry board roles: Yair Tanna is said to serve on the boards of Bakelite, Pangea (GST AutoLeather), Polynt, PTC Alliance, Running Aces and White Birch, and a Walker (described as President and Senior Managing Director) is noted as a board member for Starwood REIT and Consumer Portfolio Services, Inc. ^[1]. Those statements are firm-supplied claims and should be treated as the most direct public evidence of who the firm says it places on corporate boards ^[1].

2. What external databases and regulators show (and where they fall short)

Commercial data providers and regulatory indexes that typically catalogue private-equity portfolios—PitchBook, Fintel, Bloomberg, SEC adviser summaries and Tracxn—carry profiles of Black Diamond but either summarize holdings without comprehensive, current board lists or restrict full details behind subscriptions ^{[2] [5] [3] [4] [6]}. For example, Fintel lists a "Portfolio Holdings" entry for the firm but does not provide an immediate public master list in the snippet available ^[2], and PitchBook and Bloomberg host firm profiles that require logins for full investment and governance roll calls ^{[3] [5]}. Regulatory adviser pages exist but are summary-level and do not enumerate portfolio company boards in public extracts ^[4].

3. How to read the available evidence and its limits

The most concrete, attributable evidence for "who sits on the boards" comes from Black Diamond’s own executive bios, which mix past and present language ("has held or currently holds")—an important distinction because boards turn over and portfolio companies are bought, sold or restructured ^[1]. Publicly available, independent confirmation of current board memberships across all named portfolio firms is not present in the provided sources; therefore any definitive, up-to-the-minute list of active holdings and sitting directors would require access to company filings, current board minutes, state corporate records, or subscription databases not reproduced here ^{[2] [3]}. That gap creates room for both outdated lists and omission of private or recently exited investments.

4. Alternative viewpoints and potential agendas

Black Diamond’s website is an investor-relations document intended to showcase track record and management involvement, which creates an implicit incentive to highlight favorable board roles—past or ongoing—without providing exhaustive, timestamped disclosure ^[1]. Data vendors have commercial incentives to aggregate and sell up-to-date governance data but often gate that information; consequently, narratives derived solely from either side can be incomplete ^{[2] [3]}. Independent reporting or corporate filings would be the neutral corroboration; the sources supplied do not include such third-party confirmations on current board rosters ^[4].

5. Bottom line and next steps for verification

The public-facing evidence identifies several portfolio companies associated with Black Diamond and cites specific principals—Stephen Deckoff, Yair Tanna and Walker—as having board roles at named firms ^[1]; however, the provided sources do not supply a comprehensive, current portfolio list or a verified, contemporaneous board roster for each company ^{[2] [3] [4]}. To convert this summary into a definitive, current directory would require targeted checks of each named company’s filings or board listings, or access to subscription databases that maintain live governance records ^{[2] [3]}.
